Table of Contents What are Estradiol and Aromatase? When aromatase is unbalanced, estradiol becomes an issue Low estrogen levels in men, not testosterone increases risk of heart disease Androgen deprivation therapy can cause cognitive decline Does estradiol restore cognitive function during ADT? Should high estradiol levels be treated? What are Estradiol and Aromatase? Estradiol is a form of the female hormone estrogen. Although estradiol production is typically considered a female concern, men also need to maintain healthy levels of this hormone for optimal health. Since men lack ovaries (where most estradiol is produced in women), estradiol in men is created by a process that uses an enzyme called aromatase (1) in testicles, liver and fat cells. Aromatase converts a very small portion of testosterone levels into estradiol, and health problems can arise when aromatase levels are too high or too low (1). When aromatase is unbalanced, estradiol becomes an issue As men age, they can experience excess aromatase activity, raising estradiol levels and reducing testosterone to unhealthy levels. Low T levels will adversely impact quality of life by reducing libido, ability to maintain an erection, mood, and muscle mass, among other health factors (2). However, when the body produces too little aromatase, men can experience other, potentially serious health problems. Men with diminished aromatase levels will have an estradiol deficit, which can create problems similar to low-T; diminished sex drive, loss of bone mass, and increased body fat (3). Men on testosterone replacement therapy (TRT) taking higher doses of aromatase inhibitors can also experience estradiol deficit. Let’s look at recent studies finding that low estradiol can play a critical role in increasing the risk of cognitive decline and increase the odds of experiencing cardiovascular disease. Low estrogen levels in men, not testosterone increases risk of heart disease A study led by Elaine Yu, MD, MSc, addresses the suspicion held by many medical professionals that testosterone can promote cardiovascular disease in men, and that estradiol provides protection against it (4). The researchers sought to determine whether it was estradiol or testosterone that regulated men’s cardiovascular risk factors by comparing two groups whose hormone levels were changed using a combination of medications (4). They looked at 400 healthy men, between the ages of 20 and 50. Study participants were weighed, had fasting blood tests for markers of heart disease and diabetes, and also had a thigh scan using quantitative computed tomography (CT scan) to measure muscle fat content before and after the study (4). Yu’s team found that while higher levels of testosterone reduced these men’s levels of healthy (HDL) cholesterol, changes in estradiol levels had no effect at all on HDL(4). However, they also discovered that low estradiol levels did increase the markers for diabetes, like increased insulin resistance, increased fat in the muscles, and higher fasting blood sugar levels(4). Diabetes is a major risk factor for heart disease (5). Additionally, the study found that neither estradiol nor testosterone affected the levels of LDL (unhealthy) cholesterol. According to Yu, these findings indicate that in men, it’s higher testosterone levels combined with lower estradiol levels that can worsen cardiovascular risk factors, somewhat explaining differences in the incidence of heart disease between men and women. Some studies have shown that it is the ratio of testosterone to estradiol that is important, not just the level of each of those hormones. As testosterone increases with TRT, so does estradiol to balance the effects of testosterone on lipids, mood and insulin action. Androgen deprivation therapy can cause cognitive decline Androgen deprivation therapy (ADT) is an often used method to slow the growth of prostate cancer. It’s also used for men transitioning to women (6, 7). ADT is typically prescribed on an open-ended (no fixed period) basis to help treat advanced prostate cancer. An estimated 44 percent of men with prostate cancer will undergo ADT at some point as part of a strategy to slow tumor growth (6). ADT therapy is used specifically to block the male hormones, particularly testosterone, from stimulating prostate cancer cell growth. Research has confirmed that ADT can cause significant cognitive decline in women with breast cancer (8), but few studies have investigated cognitive impairment following ADT for men being treated for prostate cancer. Using formal tests, scientists recently compared the cognitive ability of 58 prostate cancer patients receiving androgen deprivation therapy to 84 prostate cancer patients who did not receive ADT, and 88 cancer-free men (9). They found that those treated with ADT were 70 percent more likely to develop cognitive impairment after six months, and over twice as likely to have significant cognitive impairment after one year(9).   Does estradiol restore cognitive function during ADT? A 2018 study published in Current Neuropharmacology has examined whether estradiol supplementation is an effective way to prevent this side effect (9). Researchers performed a literature search using PubMed and Google Scholar to identify studies on this topic and discover any evidence that estradiol supplementation has a cognitive benefit for men on ADT. They examined studies involving the effects of estradiol treatment on cognitive function in three androgen-deprived male populations; prostate cancer patients, male-to-female transsexuals, and castrated male animals (9). A review of the literature found that while some studies show that estradiol supplementation resulted in cognitive improvement (especially in spatial ability), They couldn’t determine (9): Whether estradiol will improve cognition after long-term ADT How early or delayed estradiol treatment post-castration will affect cognition If estradiol affects memory retention They conclude that for androgen-deprived males, there is some evidence that estradiol supplementation may improve both verbal and visual memory (9). However the variability between the reviewed studies resulted in significant inconsistencies, making further study necessary to determine what estradiol treatment protocol can best maximize cognitive improvement for men using ADT (9). Should high estradiol levels be treated? Men on testosterone replacement therapy can experience an increase in estradiol that can sometimes reach clinically elevated levels (10). A study published in the Journal of Sexual Medicine (11) looks at the phenomenon of increased estradiol levels in men undergoing TRT to discover whether high estradiol levels in this population should be treated. Researchers comprehensively reviewed the published literature on the role of estradiols in male sexual function and testosterone deficiency to answer this question. The study findings reveal that (11): Although estradiol have been used at pharmacologic doses to suppress serum testosterone, there is no evidence that naturally occurring elevations of estradiol will cause a reduction in testosterone levels Absent testosterone deficiency, study findings suggest that elevated estradiol levels don’t seem to be harmful. Once again, monitoring and treating the ratio of testosterone to estradiol may be more important than either hormone alone. Estradiol could help maintain some sexual function in castrated men Given the evidence uncovered by this review study, researchers report that, although further research is needed, the existing evidence doesn’t support the treatment of elevated estradiol for men on testosterone therapy (11).

Estradiol in Men: What is the Most Accurate Blood Test? Table of Contents Estradiol in Men: What is the Most Accurate Blood Test? Comparisons of Immunoassay and Mass Spectrometry Measurements of Serum Estradiol Levels and Their Influence on Clinical Association Studies in Men Objective: Design and Setting: Main Outcome Measures: Results: Conclusions: BUY SENSITIVE ESTRADIOL TEST HERE  Recent studies show the importance of estradiol in men and how low estradiol can be detrimental for not only for bone but also for sex drive. Low estradiol has also been linked to fat gain. So, physicians should be careful about treating men who are obviously being over diagnosed with high estradiol due to the use of the wrong test. This study compares the old estradiol blood test assay (ECLIA) to the more accurate sensitive one (LC/MS/MS). The sensitive estradiol test is a method for measuring estradiol levels in men (and children) using a sensitive liquid chromatography-tandem mass spectrometry (LC/MS)-based assay[2]. It is considered more accurate for men because it provides better sensitivity and accuracy at lower estradiol concentrations, which are typically found in men, as opposed to higher concentrations found in adult females[1][2]. Immunoassay-based estradiol tests, on the other hand, perform best at higher concentrations of estradiol, making them more suitable for individuals with levels in the adult-female range[2]. The sensitive estradiol test, with its greater sensitivity at lower levels, is more appropriate for men who generally have lower levels of estradiol compared to adult females[3]. Comparisons of Immunoassay and Mass Spectrometry Measurements of Serum Estradiol Levels and Their Influence on Clinical Association Studies in Men  (Source: The Journal of Clinical Endocrinology & Metabolism, Volume 98, Issue 6, 1 June 2013, Pages E1097–E110)   Immunoassay-based techniques, routinely used to measure serum estradiol (E2), are known to have reduced specificity, especially at lower concentrations, when compared with the gold standard technique of mass spectrometry (MS). Different measurement techniques may be responsible for the conflicting results of associations between serum E2 and clinical phenotypes in men. Objective: Our objective was to compare immunoassay and MS measurements of E2 levels in men and evaluate associations with clinical phenotypes. Design and Setting: Middle-aged and older male subjects participating in the population-based Osteoporotic Fractures in Men (MrOS) Sweden study (n = 2599), MrOS US (n = 688), and the European Male Aging Study (n = 2908) were included. Main Outcome Measures: Immunoassay and MS measurements of serum E2 were compared and related to bone mineral density (BMD; measured by dual energy x-ray absorptiometry) and ankle-brachial index. Results: Within each cohort, serum E2 levels obtained by immunoassay and MS correlated moderately (Spearman rank correlation coefficient rS 0.53–0.76). Serum C-reactive protein (CRP) levels associated significantly (albeit to a low extent, rS = 0.29) with immunoassay E2 but not with MS E2 levels. Similar associations of immunoassay E2 and MS E2 were seen with lumbar spine and total hip BMD, independent of serum CRP. However, immunoassay E2, but not MS E2, associated inversely with ankle-brachial index, and this correlation was lost after adjustment for CRP (C Reactive Protein- An Inflammatory marker). Conclusions: Our findings suggest interference in the immunoassay E2 analyses, possibly by CRP or a CRP-associated factor. Although associations with BMD remain unaffected, this might imply for a reevaluation of previous association studies between immunoassay E2 levels and inflammation-related outcomes.

Are estrogen tests accurate? Can estradiol test wrong? What is the best estradiol test? What day is best to test estradiol? Conclusion Importance of Accurate Estradiol Testing in Males Measuring estradiol levels accurately is crucial for men's health, as low estradiol can negatively impact bone health, sex drive, and may lead to fat gain. It is essential for physicians not to overdiagnose high estradiol due to using an inaccurate test. In recent years, the importance of accurate estradiol testing has become more apparent with increasing awareness about its role in various aspects of male reproductive health. The Role of Estradiol in Men's Health Bone Health: Low estradiol levels have been linked to a higher risk of osteoporosis and fractures in men. Maintaining optimal serum estradiol levels helps preserve bone mineral density and prevent age-related bone loss. Sex Drive: Although testosterone plays a significant role in regulating libido, adequate estradiol concentrations are also necessary for maintaining healthy sexual function. Fat Gain: Studies have shown that low estrogen levels can contribute to increased abdominal fat accumulation and reduced insulin sensitivity in males. To ensure proper diagnosis and treatment strategies for patients experiencing symptoms related to imbalanced hormones like estrogen (estradiol), healthcare professionals must use the most accurate methods available when measuring these critical biomarkers. One such method gaining popularity among practitioners is the sensitive liquid chromatography-tandem mass spectrometry (LC/MS) assay - a highly precise technique capable of detecting even minute amounts present within blood samples taken from individuals being assessed during routine checkups or follow-up visits following initiation onto hormone replacement therapy regimens (source). Why Traditional Estradiol Tests May Not Be Sufficient for Men Immunoassays like ECLIA (Electrochemiluminescence Immunoassay) are frequently used to measure female estradiol levels. However, these tests may not be suitable for accurately determining low estradiol levels typically found in men due to their limited sensitivity and specificity at lower concentration ranges. Inaccurate test results can lead physicians to misdiagnose patients with high or low estradiol concentrations, potentially resulting in unnecessary treatments or interventions that could further exacerbate existing health issues rather than alleviate them. As a result, it becomes increasingly important for healthcare providers working within this field - particularly those specializing specifically within male reproductive medicine - adopt more advanced testing methodologies capable of providing accurate assessments regardless of whether someone has too much/too little circulating throughout their system (source). Immunoassay-based estradiol tests should be employed with caution, as their accuracy can be compromised by various factors. Understanding these limitations is critical for ensuring reliable results in male health monitoring. By better understanding potential interference from C-reactive protein (CRP) as well as the inaccuracy at lower concentration ranges, we can better assess our risk factors and make informed decisions about our health.   Key Takeaway:  Discounted Labs offers low-cost lab tests without a doctor's visit in many U.S. cities, and the topic of accurate estradiol testing is being discussed. Limitations of Immunoassay-Based Estradiol Tests Traditional immunoassay-based techniques, such as ECLIA (Electrochemiluminescence Immunoassay), have been widely used for measuring estradiol levels in the past. Immunoassay-based techniques, like ECLIA, are not as precise when detecting estradiol levels at lower concentrations that are more common in men. This can lead to misleading results and incorrect diagnoses or treatment plans. Inaccuracy at Lower Concentration Ranges Immunoassays perform best at higher concentrations suitable for adult females but struggle with precision and accuracy at the lower ranges commonly seen in males. As a result, they may overestimate or underestimate estradiol levels in men due to their limited sensitivity within this range (source). Consequently, healthcare professionals relying on these tests might not be able to make informed decisions about hormone management or monitoring testosterone replacement therapy. Potential Interference from C-Reactive Protein (CRP) Besides being inaccurate at lower concentration ranges, immunoassays can also be influenced by other factors present in blood samples that could interfere with test results. One such factor is C-reactive protein (CRP), an inflammation marker associated with various health conditions like obesity and cardiovascular disease. Interference: CRP has been shown to bind non-specifically with antibodies used in some immunoassays, leading to falsely elevated estradiol levels in men (source). Inflammation-related outcomes: Previous association studies between immunoassay E2 levels and inflammation-related outcomes might need reevaluation due to this potential interference. In light of these limitations, it becomes essential for healthcare professionals conducting hormone assessments on their patients' behalf - especially if they're trying accurately determine whether someone has too much or too little circulating throughout their system - opt instead for highly precise LC/MS technology rather than relying solely upon outdated methods employed previously via standard assays alone so as to ensure optimal results every time without fail. C-reactive protein (CRP) may have an impact on immunoassay-based estradiol tests, which can be inaccurate at lower concentration ranges. However, a more sensitive LC/MS test offers improved accuracy with reduced interference from CRP or associated factors.   Key Takeaway:  Discounted Labs offers lab tests without a doctor's visit in most U.S. cities, and the topic of accurate estradiol testing is being discussed. Advantages of Sensitive LC/MS Estradiol Test for Males The LC/MS assay offers greater sensitivity and specificity than traditional immunoassay-based techniques, such as ECLIA, for measuring estradiol levels in men at the lower concentrations typically found. These benefits include better sensitivity and accuracy at the lower concentrations of estradiol typically found in males, ensuring precise measurements without potential interference from other factors. Improved Sensitivity and Specificity One significant advantage of using the sensitive LC/MS estradiol test is its ability to accurately measure lower concentrations of this hormone. This is particularly important for men since their normal range falls within these low concentration levels. Healthcare professionals are better equipped to make decisions about potential treatments or lifestyle adjustments when they have access to more precise measurements. Reduced Influence from CRP or Associated Factors A study published in The Journal of Clinical Endocrinology & Metabolism revealed that immunoassay-based tests could be influenced by C-reactive protein (CRP) or associated factors, which might cause interference during analysis. The sensitive LC/MS assay significantly lessens this influence, allowing for more accurate results that are independent of outside factors. In addition to these advantages, the use of sensitive LC/MS technology ensures consistent results across different laboratories and testing facilities due to its standardized methodology. As a result, patients and healthcare providers can trust the accuracy and reliability provided by this advanced method of estradiol testing. The advantages of the sensitive LC/MS estradiol test for males are clear: improved sensitivity and specificity, as well as reduced influence from CRP or associated factors. It is critical to assess how these tests stack up when measuring inflammation-related results by looking into a comparison between immunoassay and mass spectrometry evaluations. "Get accurate and reliable estradiol testing with the sensitive LC/MS assay. Say goodbye to potential interference from external factors. #healthcare #hormonalimbalance" Click to Tweet Study Comparing Immunoassay and Mass Spectrometry Measurements A study published in The Journal of Clinical Endocrinology & Metabolism aimed to compare the accuracy of immunoassay-based estradiol tests with mass spectrometry measurements among middle-aged and older male subjects participating in various population-based studies. This comparison was essential for understanding the limitations of traditional methods like ECLIA when measuring serum estradiol levels, particularly in men. Moderate Correlation Between Testing Methods The study found that, within each cohort, serum E2 levels obtained by immunoassay correlated moderately with those measured by mass spectrometry (MS). However, this moderate correlation does not guarantee equal accuracy between the two methods, especially when measuring low estradiol levels typically found in men, which may influence inflammation-related outcomes. Instead, it highlights a potential discrepancy when using immunoassays for measuring low estradiol levels typically found in men. Influence on Inflammation-Related Outcomes The researchers uncovered a potential issue when utilizing immunoassays to gauge low estradiol concentrations normally found in men - the measurements were affected by C-reactive protein (CRP) or CRP-related components, potentially interfering with analysis. This means that previous association studies between immunoassay E2 levels and inflammation-related outcomes might need reevaluation due to this potential interference. This discovery further emphasizes the importance of using sensitive liquid chromatography-tandem mass spectrometry (LC/MS)-based assays for accurate measurement of serum estradiol levels in males. By opting for LC/MS technology over outdated methods like standard assays alone, healthcare professionals can ensure optimal results without fail while monitoring hormone management or testosterone replacement therapy among their patients experiencing issues like fatigue or erectile dysfunction resulting from imbalanced hormones like estrogen (estradiol). This research has revealed a moderate association between immunoassay and mass spectrometry measurements, with potential ramifications for inflammatory effects. Moving on to the next heading, we will explore how these findings can be used to improve hormone management and testosterone replacement therapy monitoring.

The most accurate method for testing estrogen levels, specifically estradiol, is liquid chromatography-tandem mass spectrometry (LC/MS). This technique offers improved sensitivity and specificity compared to immunoassay-based tests. Studies have shown that LC/MS provides more reliable results in both males and females. Are estrogen tests accurate? Estrogen tests can be accurate, depending on the method used. At lower concentration ranges, immunoassay-based tests are less reliable and may be subject to interference from C-reactive protein (CRP). However, sensitive LC/MS methods offer greater accuracy due to their enhanced sensitivity and reduced influence from CRP or associated factors. Can estradiol test wrong? Estradiol tests can sometimes produce inaccurate results if using an immunoassay-based method, especially in males with low concentrations of estradiol. The presence of CRP or other interfering substances may also affect the accuracy of these tests. Opting for a sensitive LC/MS test reduces the likelihood of erroneous results. What is the best estradiol test? The best estradiol test is one that uses liquid chromatography-tandem mass spectrometry (LC/MS), as it offers superior sensitivity and specificity compared to traditional immunoassays. This makes it particularly suitable for accurately measuring low concentrations of estradiol in males undergoing hormone management or testosterone replacement therapy monitoring. What day is best to test estradiol? For women, the best day to test estradiol depends on their menstrual cycle. In general, it is recommended to test estradiol levels during the follicular phase of the cycle (days 2-4). For men and postmenopausal women, there are no specific days for testing; however, consistency in timing can help monitor changes over time. Conclusion Accurate estradiol testing is essential for monitoring hormone management and testosterone replacement therapy in males. The results of a recent study comparing immunoassay-based tests to LC/MS measurements demonstrate that the latter are far more sensitive, reliable, and accurate. Therefore, it is recommended that all men undergoing hormone management or testosterone replacement therapy use an LC/MS test when checking their estradiol levels. Accurate data is essential to enable informed decisions regarding medical care, so LC/MS testing should be employed when evaluating estradiol levels in men undergoing hormone therapy or testosterone replacement.

According to the National Institute of Health, gynecomastia can affect more than 50% of adolescent boys during puberty. At the same time, gynecomastia can also affect up to 65% of men between 27 and 92 years, depending on their lifestyle, habits, drug intake, and other factors. But what is gynecomastia and why so many men get it? Is it dangerous? And what can you do to treat it effectively and safely? Keep reading this article to find out everything you need to know about gynecomastia, its types, causes, and treatment options. Table of Contents What is Gynecomastia? What Kinds of Gynecomastia Are There? Physiological Gynecomastia Neonatal Gynecomastia Pubertal Gynecomastia Aging Gynecomastia What Hormone Inbalances Can Cause Gynecomastia? Pharmacological Gynecomastia Caused by Medications How to Treat Gynecomastia Gynecomastia FAQ What is Gynecomastia? In simplest terms, gynecomastia is commonly known as “man boobs.” It’s a health issue characterized by an increase of the breast tissue in adolescent boys as well as adult males. Although this type of condition doesn’t usually pose serious health risks, it can have profound psychological consequences. Men simply don’t like having breasts which look like those of women. The prevalence of gynecomastia in seniors over 50 years of age is approximately 70%. In rare cases, untreated gynecomastia can lead to different types of diseases, including breast cancer, so that’s why it’s essential to accurately diagnose and treat them. Gynecomastia can also be referred to as male breast enlargement, and it splits into three main categories - physiological, pathological, and pharmacological. Let’s take a closer look at each one.   What Kinds of Gynecomastia Are There? Physiological Gynecomastia This type of gynecomastia is usually caused by an imbalance in the testosterone and estrogen ratio in the body. As you probably know, these two are the essential sex hormones, and they need to be present in specific quantities in the bloodstream in both males and females. For example, men have 40 times more testosterone than females, but they also have small amounts of estrogen. This estrogen helps with libido, bone density, and other critical bodily functions. Women have higher quantities of estrogen, but small amounts of testosterone for libido, muscle mass, mood, etc. Men who have relatively more estrogen than necessary to balance testosterone tend to develop gynecomastia. This can be caused by various factors. Neonatal Gynecomastia It usually happens at birth when the ratio of estrogen to testosterone is imbalanced. It should resolve itself after a few weeks. Parents must seek a doctor's help if the gynecomastia persists after one year. Pubertal Gynecomastia This type of gynecomastia usually happens among teenagers who reach puberty. The balance of estrogen to testosterone goes out of whack, and the breasts of adolescent boys grow more than usual. The issue should get resolved automatically in less than two years. If it doesn’t more investigations are required to determine the cause of this type of gynecomastia. Aging Gynecomastia Adult males who get old will also experience mild gynecomastia, which is caused by advanced age. This process happens as a result of an increase in aromatase activity. In other words, the brain, fat tissue, liver and testicles convert a larger portion of testosterone into estrogen. The resulting higher estrogen to testosterone ratio causes aging gynecomastia.   What Hormone Inbalances Can Cause Gynecomastia?   This type of gynecomastia is usually caused by an increase in estrogen hormones, a decrease in androgen hormones or a combination of both. Here are a few hormone inbalances that can cause gynecomastia: 1. Androgen deficiency Gynecomastia can be caused by a testosterone deficiency in males of all ages. When testosterone levels drop, estrogens become more prevalent and might dictate a breast enlargement in men. In such cases, gynecomastia acts as a symptom of testosterone deficiency and it helps individuals become aware of this health issue. Testosterone deficiency is usually associated with a higher aromatization rate (which converts more testosterone to estrogen) and a decrease in the production of luteinizing hormone (LH). The Klinefelter Syndrome is usually associated with hypogonadism in those patients. Unfortunately, this health issue can increase the likelihood of developing breast cancer; that’s why it’s crucial to test the testosterone levels as soon as possible if gynecomastia is observed in patients. Breast enlargement caused by androgen deficiency can be treated with testosterone replacement therapy (TRT). In these cases, testosterone is administered in an exogenous manner by using injections, creams, pills, gels, etc. 2. Hyperprolactinemia Hyperprolactinemia is a health condition in which a male has higher levels of the hormone prolactin in his bloodstream. Prolactin is a hormone present in all mammals which allows them to produce milk. Hyperprolactinemia might be caused by a type of growth on the pituitary gland, a condition known as a prolactinoma. This growth triggers an increase in the production of prolactin, which causes hyperprolactinemia. Certain medications can cause increased prolactin. One side effect of this condition is gynecomastia. 3. Estrogen Excess Different types of estrogens cause an increase in breast development in both males and females. However, males tend to have a much smaller amount of estrogen in their bodies, so the breast enlargement stops after a while. In some cases, an excessive amount of estrogen can be produced, which leads to gynecomastia. Tumors tend to cause excess estrogen production, which in turn leads to gynecomastia. The administration of exogenous estrogens can also trigger gynecomastia in males of all ages. Patients who develop tumors also experience other symptoms such as Cushing's syndrome, weight loss, and an accumulation of fat in the abdominal area. In some cases, gynecomastia can also be a symptom of more severe disease such as testicular cancer. People who have gynecomastia should also receive a thorough investigation of the testicles to see if more serious health issues are present. 4. Thyroid Problems The thyroid gland is a vital contributor to the healthy development of a male. Conditions such as hypothyroidism or hyperthyroidism can lead to abnormal secretion of testosterone, decreasing the levels of this hormone in the bloodstream. As a result, estrogens become more prevalent, and they cause gynecomastia in most patients. If patients are assessed, and their gynecomastia is caused by thyroid issues, receiving thyroid treatment is the most appropriate solution. After the thyroid hormonal balance is restored, gynecomastia usually goes away on its own. 5. Obesity People who are obese usually have gynecomastia as well. This happens because the aromatization of testosterone into estrogen occurs in the adipose tissue. As a result, having more fat around the body allows more testosterone to be converted into estrogen, which results in breast enlargement. 6. Growth Hormone Excess Another cause of gynecomastia might be represented by an excessive amount of growth hormone and IGF-1 in the bloodstream. These hormones are responsible for growing muscle mass and bones. Studies show a correlation between gynecomastia in pubertal boys and a high amount of growth hormone and IGF-1 in the blood. Men using growth hormone or growth hormone releasing hormones should be aware of this issue. 7. Other Causes Gynecomastia might also be caused by different other health conditions. For example, chronic liver disease can significantly decrease testosterone production, which leads to breast enlargement and gynecomastia. Resuming a healthy diet after a long period of starvation can also cause gynecomastia. That's because, during periods of food scarcity, the production of testosterone is reduced. Testicular damage might also trigger enlargement of breasts in men.   Pharmacological Gynecomastia Caused by Medications   It has been discovered as a result of numerous studies that gynecomastia can also be caused by various drugs. For example, some medications can reduce testosterone production; others might cause an increase in estrogen hormones or disrupt the sensitivity of androgen receptors. Opioids can also cause gynecomastia. 1. Performance-Enhancing Drugs (PEDs) in Athletes It is a well-known fact that various performance-enhancing drugs are taken by athletes and non-athletes to increase their sports performance. Anabolic-androgenic steroids (AAS) are usually used to increase muscle mass, reduce recovery time, and improve sports performance. One side effect of abusing such drugs is the development of gynecomastia since most anabolic steroids shut down the body’s own testosterone production, which increases the estrogen to testosterone ratio. Abusing PEDs cause breast enlargement in men because it increases the aromatization process. This converts more testosterone into estrogen and gynecomastia appears as a result.  After a prolonged period of abuse, other health complications can arise, such as erectile dysfunction and infertility. 2. Getting Exogenous Estrogen The estrogen hormone can be absorbed into the bloodstream in various ways and usually accidentally. For example, animals who are treated with estrogen-rich food or drugs are eaten by men who absorb some of these hormones. Similarly, some creams which are used to treat baldness can cause an increase in estrogen production, which leads to gynecomastia. Similarly, soy-based products tend to contain estrogens (known as phytoestrogens), which can get into the bloodstream. Lavender and tea tree oil also contain phytoestrogens and are commonly found in food and cosmetics. 3. Using Recreational Drugs Different types of drugs, such as marijuana can also cause gynecomastia if abused. The experts are not yet aware of why this process happens, but there is a health condition known as marijuana-induced gynecomastia. It is believed that this drug can reduce the production of testicular testosterone, which leads to hypogonadism and gynecomastia.   How to Treat Gynecomastia As you probably have figured it out, there's no one-size-fits-all treatment for gynecomastia in men. This condition can be a problem by itself, or it can be a symptom of a more severe health issue which needs to be investigated immediately. As a general rule of thumb, gynecomastia can be caused by an increased aromatization of testosterone to estrogen, increased IGF-1, decrease thyroid function with or without a decrease in testosterone production. These two conditions can be triggered by drug abuse, organ damage, genetics, or other factors. Once the first physical symptoms are observed, the patient needs to visit his healthcare provider immediately to do more investigations. Gynecomastia is characterized by an increase of the hard to the touch breast tissue, especially under the nipple area. Therefore, it shouldn’t be confused with fat mass. The doctor can perform various investigations such as doing a blood test for testosterone and/or for estrogen levels. Depending on these results, the doctor might recommend other tests to discover why the testosterone to estrogen ratios are unbalanced. If testosterone blood levels are low, doctors prescribe testosterone replacement therapy.  If estrogen is high while testosterone is normal, doctors usually prescribe tamoxifen.  However, certain more advanced gynecomastia cases require surgery to extract breast gland tissue. In some cases, gynecomastia is caused by other underlying issues. For example, if it's caused by thyroid problems, the thyroid gland must be treated with appropriate medication. If gynecomastia is caused by liver damage, addressing the liver might help to fix gynecomastia for good. Those who are obese should consider losing weight to alleviate their gynecomastia symptoms. Entering a weight loss program and eating healthier foods can facilitate the process of losing weight.   Gynecomastia FAQ Here are a few answers to some of the questions you might have about gynecomastia. 1. Is Gynecomastia Painful? Some patients might experience mild pain in their chest area as well as tenderness, especially when gynecomastia gets into an advanced state. However, the pain is not sharp or intense, and it usually goes away once proper treatment for gynecomastia is administered. 2. Does the Breast Tissue Subside Once Gynecomastia Is Treated? One of the main concerns of patients with gynecomastia is whether the breast tissue will continue to "hang" after the condition is treated. Unfortunately, the tissue will not subside on its own in most cases, but there are solutions to this problem. Once the underlying cause of gynecomastia is treated, patients can perform small surgeries to remove the excess breast tissue and achieve a more "manly" chest. 3. Does Scarring Occur After Removing the Breast Tissue? Luckily, the scarring is minimal around the nipple area and almost invisible. Patients can go to the beach and not worry that someone will see that they had gynecomastia surgery because the scarring is virtually non-existent. 4. Are There Any Other Drugs or Substances Which Cause Gynecomastia? Certain drugs or substances might cause gynecomastia such as marijuana, steroids, or other performance-enhancing drugs. However, men might develop breast tissue enlargement as a result of consuming high amounts of alcohol too. Alcohol can damage the liver, which in turn decreases the production of testosterone. At the same time, certain drugs such as spironolactone, ketoconazole, and others can also trigger the development of gynecomastia. Cimetidine, which is a drug used to treat ulcer, is also associated with this type of health issue. Conclusions Treating gynecomastia can be done with relative ease these days, as long as you are aware of its existence. For a complete and thorough test which helps you diagnose this condition quickly, check out the Gynecomastia Test Panel. This lab test panel provided by Discounted Labs can be done using a blood sample, and you get the results in just a few business days. The results can help your doctor decide what therapies are best for you to eliminate your gynecomastia.   Reference: Sansone A, et al. Gynecomastia and hormones. Endocrine.

The bound testosterone is attached to either sex hormone-binding globulin or albumin. The free testosterone is available in small quantities in comparison with the bound testosterone. A small portion of it is converted to estrogen using the enzyme called “aromatase”. Although estrogen is a female sex hormone, it plays an important role in a male’s body too. For example, estradiol, a type of estrogen, is vital for proper sexual functioning and libido in men. However, too much estrogen can be detrimental, leading to poor sexual functioning, poor erections, accumulation of fat in the abdominal area and male boobs (gynecomastia). During testosterone replacement therapy (TRT), some men take drugs to inhibit aromatase and prevent it to convert too much testosterone into estrogen. these drugs inhibit the aromatase enzyme. Although this might sound like a good idea at first, altering the normal production of aromatase can lead to brain inflammation, studies suggest. The levels of aromatase and estrogen have been measured in injured brains and it has been discovered that the aromatase enzyme increased to protect the damaged neurons and the connections between them. Evidence concludes that inhibiting the normal levels of aromatase can lead to inflammation in healthy brains and more injury to already damaged brains. This happens because the aromatase/estrogen expression is moved from neurons to astrocytes which are a different type of brain cells. Astrocytes act as a cushion for neurons and they are usually more active when brain injury is detected. These cells can help with the healing process, but if they stay active for too long, this can lead to further damage to the brain. Studies also show that an insufficient amount of brain aromatase can indicate neurodegenerative diseases such as Alzheimer's. Low amounts of aromatase can increase plaque development which damages the brain. That’s why it is recommended to be careful when taking an aromataseinhibitor during testosterone replacement therapy as this drug might mess with the normal levels of aromatase and lead to brain complications.   Estrogen and its beneficial effects in bodybuilding Estrogen, one of the most important female sex hormone, is vital for professional athletes who aim at increasing their muscle mass. For example, estrogen can increase the anabolic response by modifying the way glucose is processed in muscle tissue. This hormone can influence the amounts of glucose 6-phosphate dehydrogenase which is directly correlated to muscle growth and repair. In other words, having adequate amounts of estrogen can maximize muscle gains and strength. In studies performed on rats, estrogen has also been correlated with a whopping 480% increase in methyltrienolone which is an androgen connected to the levator ani muscle. The production of growth hormone and IGF-1 (insulin-like growth factor) are also influenced by estrogen. This female sex hormone can increase the proliferation of IGF-1 in body tissues and liver which leads to greater muscle gains and protein synthesis. Estrogen also plays an important role when it comes to serotonin production. Serotonin is known for regulating the sleep/waking cycle. Bodybuilders who take aromatase inhibitors as drugs might have low levels of estrogen in the body. This can alter the serotonin production and lead to a thing called “steroid fatigue”. This is usually characterized by a general feeling of tiredness which can interfere with training regimes and prevent the athlete from performing at his peak. Maximizing muscle gains can be difficult in this case. Estrogen function in men and why inhibiting its production can be detrimental.  The aforementioned aromatase inhibitors are taken orally while one of them can be injected. There haven’t been studies assessing the short-term symptoms of these drugs on the physiology of an athlete. However, although drugs which inhibit aromatase and subsequently reduce estrogen levels are not usually used for a long period of time, they can cause problems when the estrogen drops under the normal range limit. Estrogen, particularly estradiol, is a powerful hormone which influences multiple body processes in both men and women. For example, estrogen can be anabolic in certain tissues such as bone and fat. It directly impacts bone density and can influence how much fat the body accumulates, particularly in the abdominal area. Estrogen can also have a stimulatory role and it influences protein production in the liver. It has a metabolic effect in the endocrine system and influences the binding globulins for vitamin D. Estrogen is also a neurosteroid influencing neurotransmitters in the brain. This can have an effect on emotions, motivation, and other functions. Since estrogen is so important in the human body, it is safe to assume that reducing it to dangerously low levels using drugs can have negative consequences on health. Similarly, having estrogen levels above the normal limit can also be detrimental for a male’s body. The key is to maintain balance when it comes to estrogen levels and make sure that estradiol E2 doesn’t drop below 20pg/mL.   The effects of aromatase inhibition on bone mineral density in older men A study was conducted at a tertiary care academic center in Boston, MA, measuring the levels of testosterone and estradiol of 69 men over 60 years of age. The participants had borderline or low testosterone levels and the study included a placebo group. The purpose of the study was to determine the effect of aromatase inhibition on bone mineral density and bone turnover. Each participant received 1 mg of an aromatase inhibitor daily or a placebo drug. At the end of the study, the serum testosterone increased from 319 ± 93 ng/dl at baseline to 524 ± 139 ng/dl in month 3 and dropped slightly after one year. The estradiol levels also decreased from 15 at baseline to 12 after 3 months and remained there. The bone mineral density decreased in the aromatase inhibitor group in comparison with the placebo group. Taking aromatase inhibitors reduce the amount of testosterone which is converted to estradiol and because participants had less estradiol in their bloodstream, their bone mineral density also dropped. This concludes that estradiol is important for bone mineral density, particularly in older men. Is anastrazole for men a good idea?   High estrogen levels and prostate cancer Some studies conclude that high levels of estrogen might help develop prostate cancer cells, but men who already have prostate cancer don’t have high levels of estrogen in the bloodstream. Other studies show that a sharp increase in estrogen levels might lead to prostate cancer, but more information is required to reach a definitive conclusion. A small part of the free testosterone which circulates through the bloodstream is converted into estrogen. This hormone is required for maintaining proper health and avoiding cardiovascular diseases as well as diabetes type 2. On the other hand, low testosterone levels have also been associated with an increase in prostate cancer cells. A significant body of evidence indicates that high estrogen levels might be dangerous for men and affect their prostate only when testosterone levels are too low. Increasing testosterone levels through TRT (testosterone replacement therapy) will also increase estrogen levels in a natural way, but this doesn't automatically mean that the risk of prostate cancer will be higher. Approximately 50 years of studies show that testosterone administration alone doesn’t lead to prostate cancer.   Testosterone’s conversion to estrogen is important to eliminate anxiety and depression It is estimated that approximately 20 million adults in the United States are affected by depression each year. Many of these people receive antidepressants and anti-anxiety drugs, but this medicine can have different effects on certain people and they don’t come without side effects. Testosterone plays an important role in reducing anxiety and depression feelings in men, while estrogen and progesterone also act together as a protective mechanism against depression in women. Women, in particular, are 70 percent more predisposed to depression during their lifetimes, in comparison with men. However, certain low-testosterone males also develop depression and antidepressants seem to be inefficient for them. New evidence suggests that the conversion of testosterone to estrogen is necessary to reap the antidepressant effects of testosterone. Professor Mohamed Kabbaj reached this conclusion during his studies which were promoted by the National Institute of Mental Health. It has been discovered that there is a link between testosterone conversion to estrogen and depression in animal studies, but this link might be valid in human studies as well. This might lead to new antidepressants which impact the brain differently and are more efficient for low-testosterone men. Testosterone influences a plethora of pathways in the brain and it can have multiple side effects. That’s why it is important to develop a drug which acts only on the pathways responsible with anxiety and depression. Some of the side effects caused by antidepressants include heart problems and these should be avoided. Better drugs are necessary to impact the brain differently and safely treat anxiety and depression feelings. Dr. Kabbaj discovered that the antidepressant effects of testosterone happen only after this hormone has been converted to estrogen. The conversion process is regulated by a special enzyme in the brain. Dr. Kabbaj inhibited this enzyme in the hippocampus area of the brain. This area is responsible for mood regulation and has a strong influence on how a person feels. When this enzyme has been inhibited, the antidepressant effects of testosterone weren’t present. This leads to the conclusion that the conversion of testosterone to estrogen is very important. Testosterone impacts the MAPK pathway in the brain to produce these positive and beneficial antidepressant effects. However, this pathway is also implicated in multiple other body processes, including cell growth and cancer. More work is required to find out ways to get the antidepressant effects of testosterone without increasing the risk of cancer. Testosterone activity in the brain Tests have been done on rats to discover the behavior of testosterone when it enters the brain. Castrated rats have been injected with estradiol instead of testosterone and the recovery process of intromission and ejaculation worked normally. The estradiol was injected into the hypothalamus. However, when DHT was injected instead of testosterone (DHT is a powerful androgen which doesn’t convert to estrogen), no recovery process was detected. This concludes that testosterone converts to estrogen when it is injected into the hypothalamus and facilitates sexual behavior. The aromatase enzyme is present in this part of the brain as well as estrogen receptors. It has also been discovered that injecting drugs which block the aromatization process of testosterone to estrogen can change the behavioral effects of testosterone and significantly influence sexual function. This means that testosterone must convert to estrogen to enable proper male sexual behavior. Further studies show that inhibiting the aromatization process in monkeys can interfere with their sexual behavior. Men who have a congenital deficiency of aromatase also have a low sex drive and they can benefit greatly from small doses of estradiol to improve sexual functioning. The testosterone’s effects on male sexuality are twofold. This hormone influences libido directly with the help of androgen receptors and indirectly using estrogen receptors. However, more work is necessary to determine the exact differences between these effects.   High estradiol levels are not correlated with erectile dysfunction Contrary to the popular belief, high estradiol levels are not associated with poor sexual function in males. A study was conducted on low testosterone centers in the United States, comprising more than 34,000 men. The participants had different ages, some of them being younger than 25 while others being older than 65. Estradiol levels were measured using electro-chemiluminescence immunoassay and it has been discovered that having too much estradiol in the bloodstream doesn’t lead to poor sex drive and erectile dysfunction. It has also been discovered that those with low or normal estradiol levels have a higher incidence of poor sex drive and potential erectile dysfunction.   Estradiol improve endothelial function in healthy men Studies show that estradiol (sometimes written as oestradiol) can improve endothelial function in healthy men. The endothelium is a very thin membrane which lines up the insides of your blood vessels and heart. It can also be found on lymph vessels. Its role is to release substances which help relax or constrict the blood vessels, depending on various factors. The endothelium is also important for controlling platelets, blood clotting and to regulate immune function in men and women. It is already known that supplementing with estrogen (particularly estradiol) is linked to a reduced incidence of cardiovascular disease in women who are deficient in this hormone. The purpose of the study is to determine if estrogen can also be beneficial for the endothelial function in healthy men. The study included 23 men aged 32 years, give or take up to 8 years. They were split into three groups. One group was given testosterone supplements alone, one group received a combination of testosterone and 10mg of estradiol and the third group received testosterone and 20mg of estradiol. These participants were measured one month and six months after multiple tests were performed to determine the influence of estradiol on their health. The study concluded that those who received estradiol supplementation had a better endothelial function. This means that administering estradiol to healthy men can improve their cardiovascular system.   Estradiol and libido, erectile function and reproduction Estradiol impacts multiple processes in a human body and it can have a strong influence on the brain. This hormone can directly influence the brain and dictate the sexual behavior of mammals, creating arousal states and moods which are conducive to reproduction. This is done by the release of pheromones. These substances can increase activity in the area anterior to the hypothalamus. Neurons play an important role in converting testosterone to estrogen using the aromatase enzyme. There are billions of neurons in the brain and they transmit electrical information 24/7, helping humans function correctly. Another important brain cell is the astrocyte. These cells help the neurons transfer information from one part of the brain to the other. They are star-shaped cells which play an important role, particularly when the brain is injured and they also use the aromatase enzyme to convert testosterone to estrogen. The anterior area of the hypothalamus contains numerous estrogen receptors. These receptors work similarly to selective serotonin reuptake inhibitors which are known for lowering sex drive. This might indicate that estrogen can significantly influence sexual functioning and behaviors in men.   How estradiol works when testosterone levels are low Having low testosterone levels can definitely lead to poor sexual functioning and lack of libido. To determine the efficacy of estradiol in men and what influences it has, it is important to analyze it in people who have normal as well as low testosterone levels. Studies have been done on men with low testosterone. They received doses of estradiol and reported an increased sexual drive. These human studies are supported by the ones performed on rats. Castrated rodents were given estrogen and it has been discovered that this increased their sexual activity. Another important finding consists of patients who had prostate cancer and received androgen deprivation therapy. This type of therapy is known to slow down or completely stop the advancing of prostate cancer since the cancerous cells require testosterone to grow. When the androgen levels reached a critical point, the patients reported symptoms which are commonly found in people who have a low sex drive and erectile dysfunction such as hot flashes and other adverse effects. It has also been discovered that androgen receptor blockers are more efficient in maintaining sexual activity in comparison with castration. This might happen as a result of testosterone conversion to estrogen. It is possible that supplementing with estradiol might make patients who undertake androgen deprivation therapy have increased brain activity in those areas responsible with sexual behavior.   Estradiol and its influence in eugonadal men (men with normal testosterone levels.) Eugonadal means men with healthy testosterone levels. Estradiol has been proven beneficial for people with low testosterone levels, increasing libido, and sexual desire. However, some studies show that the same positive results don't apply to eugonadal men. One study was performed on men with healthy testosterone levels. They received estradiol on a regular basis and they reported a decrease in sexual functioning, libido, masturbation, and erections. On the other hand, another study reported that administering estradiol to 50 men aged between 20 and 40 years didn’t influence their sexual function and libido at all. More research is required to understand how estradiol affects eugonadal men, but administering this hormone exogenously can be beneficial for people who have testosterone levels, increasing their libido and sexual desire.   Analyzing the role of estradiol on hypogonadal men who undertake testosterone replacement therapy Testosterone supplementation therapy aims to improve the quality of life of hypogonadal men as well as increase the levels of circulating testosterone in their bloodstream. This therapy also tries to increase the number of testosterone metabolites such as estradiol which is known for playing a vital role in sexual desire. In a test performed on men with secondary hypogonadism, c l o mi phene was used to increase the levels of testosterone by influencing the estrogen receptors directly. Secondary hypogonadism means that the testicles function correctly, but there is a scarcity of luteinizing hormone produced by the pituitary gland and this translates into low testosterone levels. The clomiphene citrate managed to increase testosterone levels in men with secondary hypogonadism as well as increasing the conversion of testosterone to estrogen. Other studies show that clomiphene citrate can increase sexual desire and libido. Another study performed in 2013 looked at the role of testosterone in healthy men and how it can influence sexual behavior. Some of the study participants received testosterone in combination with aromatase inhibitors, while others received testosterone without aromatase inhibitors. As a result, the sexual function was impaired when aromatization was inhibited. Other studies show that sexual desire increased significantly when men received testosterone supplementation therapy and had estradiol levels above 5 ng/dl. Even when testosterone levels were below 300 ng/dl and the estradiol levels were higher than 5 ng/dl, the sexual desire was increased. Yet another study looked at the sexual behavior of men who received l etr ozole which is a powerful aromatase inhibitor. These men had low testosterone levels and after being given le tro zole, their estradiol level dropped even lower. The result was that libido was significantly decreased. This means that both testosterone and estradiol are important in people who have testosterone deficiency to achieve and maintain healthy sexual desire and libido.   Aromatase inhibition can decrease insulin sensitivity Insulin sensitivity is extremely important when it comes to diseases such as diabetes type 2. Those who have low insulin sensitivity are more predisposed to become diabetic in the future. Inhibiting the aromatase enzyme through different types of drugs can have a significant influence on insulin sensitivity in both humans and rats. A study conducted at a clinical research facility tested 17 healthy men with ages between 18 and 50 years. This was a double-blind, controlled study. Each participant received an aromatase inhibitor, or a placebo drug for 6 weeks. The study concluded that inhibiting aromatase can lead to poor insulin sensitivity, particularly when it comes to peripheral glucose disposal.   The relationship between estrogen and bodybuilding It is well known that estrogen gives you a feeling of wellbeing and the lack of it can lead to depression, mood swings, emotional instability, and even depressive thoughts. Aromatase inhibitors can reduce the amount of estrogen the body produces and it usually makes a person feel lethargic and unhappy. For example, menopausal women seem to become more emotionally unstable and being haunted by feelings of anxiety and depression. Studies show that this can also be the case for bodybuilders and top athletes who regularly take aromatase inhibitors to convert less testosterone to estrogen. Estrogen is vital when it comes to sexual drive and libido as well and it is a well-known fact that aromatase inhibitors can negatively impact sex drive. A study on two groups of men reached the conclusion that estrogen is very important for libido. The first group received testosterone treatment alone while the second group received testosterone and an anti-estrogenic agent. At the end of the test, the group who received only testosterone treatment had better sexual drive and libido. Researchers also believe that lowering the estrogen levels too much in healthy men can lead to anxiety feelings, depression and even osteoporosis.   Estradiol and DHT can make you age more slowly Another study performed in Australia looked at the link between telomere length and the amount of serum estradiol and DHT in men. Telomeres are sequences of nucleotides at the end of each chromosome. They are used as a biomarker for aging. Having shorter telomeres means that the biological age is higher, regardless of the actual age of the person. Having longer telomeres correlated with a smaller biological age which basically means that the person is younger than his or her real age. The study performed in Australia looked at the telomere lengths of men aged 53, give or take approximately 15 years. The conclusion of the study was that estradiol and DHT correlate with telomere length and a small reduction in estradiol can amount to an approximate age increase of a decade. Estradiol alone can influence telomere length and that’s why it is important not to reduce it too much using aromatase inhibitors.   Symptoms of low estradiol in men A study performed in a medical center on several hundred men concluded that lack of estradiol can give certain vasomotor symptoms similar to those menopausal women have. These symptoms include hot flashes, sweats and flushes. The study participants were healthy men with ages between 20 and 50 years. They had normal serum testosterone levels and were split into two groups The first group of men was administered goserelin acetate which stops gonadal steroids. After 4 weeks, they received placebo drugs or different doses of testosterone gels. The second group of men received a treatment similar to those in the first group, but they also received an inhibitor of the aromatization of testosterone to estrogen. The study concluded that those who received aromatase inhibitors and had low estradiol levels experienced vasomotor symptoms such as night sweats and hot flashes. Similarly, those who received high doses of testosterone gel (approx 10 grams daily), as well as aromatase inhibitors, didn't experience the same symptoms. This means that when high amounts of testosterone are administered, it can suppress the effect of the aromatase inhibitor and leave estrogen levels intact.   Estradiol and reproductive function in men The sexual function in males is directly influenced by a mix of multiple substances and organs including testosterone, estradiol, estrogen receptors, testes, penis, and brain. The aromatase enzyme and estrogen receptors have a similar location in the brain and they are important in the development of sexual function early in life. They also influence sexual behavior in adulthood in combination with other substances called pheromones. Estrogen influences the mood and libido of a man, enabling him to alter his cognition for a mental state conducive to reproduction. Spermatogenesis is another important part of male reproduction. The creation of sperm cells relies on estradiol and these cells contain estrogen receptors and the aromatase enzyme. Men who undertake testosterone supplementation therapy should also be monitored for their estrogen levels. This is because an estradiol level below 5ng/dl can cause a significant drop in sex drive and libido.   Conclusion The role of estrogen in the male body is unquestionably important. Bodybuilders, professional athletes, and patients who undertake testosterone replacement therapy should be careful when it comes to managing estradiol levels since this hormone can significantly impact their wellbeing, sex drive, and bone density.   Get Your Estradiol Blood Test and Find Out More!

Estradiol is the most important female sex hormone, and it plays a significant role in developing female secondary sexual characteristics. It also plays a vital role in maintaining proper bone density, regulating body fat, and ensuring a strong erection in men. This type of hormone is one of the three estrogens found in the human body. The other two are called estrone and estriol. Estradiol is the most important and strongest of the estrogen hormones, and it is primarily made in testicles, fat cells, and liver. Approximately 80% of the estradiol found in a man's body comes from the aromatization of testosterone. A small amount of testosterone is converted to estradiol to maintain healthy reproductive and cognitive systems in men, among other body functions. Why is estradiol in men important? Because maintaining proper estradiol levels is paramount for ensuring the correct functioning of various body processes. For example, estradiol is involved in: · Maintaining correct HDL cholesterol levels · Improving penile sensitivity · Maintaining an emotional balance in men · Promoting high bone density There are numerous myths that circulate online when it comes to estradiol. Since this is a female sex hormone, some say that too much estradiol can give one "man boobs" or make him asexual. Although having very high estradiol levels can lead to various health issues, reducing the amount of estradiol in the body can also have negative consequences such as losing bone mass, having joint pains or having a decreased libido. Keep reading this article to learn more about estradiol and how it can negatively affect the body if it circulates in the blood in sub-optimal quantities.   Estradiol in Men Studies Maintaining optimum estradiol levels is key to flourishing health and enhanced fitness performance. There are several causes or factors which might disrupt proper estradiol balance and lead to very high or very low estradiol levels. · Various medications such as HIV meds, etc · Toxins from the environment · Various foods · Age · High Body Mass Index (BMI) To achieve correct estradiol levels in the organism, one needs to learn more about this type of hormone and find out how it influences the body. The following study analyzes how testosterone and estradiol can influence muscle development, strength and sexual function in men aged 20-50. Gonadal Steroids and Body Composition, Strength, and Sexual Function in Men Study Purpose This study aims to identify a direct relationship between testosterone and estradiol in men and various body functions and processes such as fat accumulation, muscle development, and fitness performance, libido, and sex drive, etc. Approximately 80% of the estradiol currently found in men results from the aromatization of testosterone. When if the levels of testosterone go down, estradiol levels will also be reduced, and this might lead to changes in body composition. Study methods Two groups of 198 and 202 men participated in this study. They were healthy men aged 20-50 who were carefully monitored for over 16 weeks to find differences in body composition and fitness performance. The first 198 men were given goserelin acetate which is a substance that suppresses natural testosterone and estradiol levels. They were also given a placebo gel as well as testosterone gel in different concentrations such as 1.25 g, 2.5 g, 5 g, or 10 g. The gel was administered daily. The second group received the same treatment, but they were also given an aromatase inhibitor which is a substance that prevents the aromatization of testosterone into estradiol. Study conclusions Key factors were monitored in these 400 men to determine the influence of testosterone and estradiol on muscle performance and strength, sex drive, and fat development. The study concluded that the body fat percentage increased in men who received a placebo testosterone gel or 1.25 g or 2.5 g of testosterone gel without getting anastrozole. Lean muscle mass also decreased in these men, and leg-press strength showed a significant decrease only in men who received the placebo gel. The significant increases in body fat are attributed to estrogen deficiency (suppression of the aromatization process of testosterone). Both androgen and estrogen deficiency caused a significant decrease in sexual function which was represented by sexual desire and erectile function. Men who received the placebo gel or 1.25 g of testosterone gel experienced the most significant decrease in sexual function, as opposed to those who received a higher concentration of testosterone gel. The study was funded by the National Institutes of Health and determined that decreases in testosterone levels primarily influence muscle strength and performance, decreases in estradiol can lead to a higher subcutaneous and intraabdominal fat percentages, and both androgen and estrogen deficiencies can lead to poor sexual function. Let's take a look at more negative consequences which can appear as a result of having too little estradiol in the body. Why low estrogen levels are dangerous for health and decrease fitness performance As mentioned earlier, having less-than-optimal amounts of estrogen in the body can lead to multiple health problems in men of all ages. Let's discover how low estradiol levels can hinder fitness goals or affect health. 1. Low estrogen levels prevent the translocation of Glut-4. Muscle hypertrophy is essential for fitness professionals and the protein carrier Glut-4 can help with recovery and growth by transporting nutrients from the surface to the core of the cells. However, this protein can sometimes become stubborn and remain inactive for long periods of time. As a result, insufficient amounts of nutrients are carried from the surface to the interior of the cells which might make the muscle recovery process less efficient. The role of estrogen, in this case, is to make the translocation of the Glut-4 possible which leads to a higher amount of nutrients being delivered to muscle tissues for repair and growth. Having very low amounts of estrogen can prevent the activation of this protein carrier which is a significant loss for any fitness professional or bodybuilder. 2. Low estrogen levels allow myostatin to interfere with the muscle-building process. As you probably already know, myostatin is an important suppressor of muscle growth in both males and females. It can be extremely powerful as presented in various studies and experiments performed on animals. For example, animals which had their myostatin gene removed experienced dramatic increases in muscle mass, sometimes reaching up to 100% more muscle in comparison with animals which haven’t been genetically altered. Studies show that the elevated estrogen levels in women can prevent myostatin from interfering with the muscle-building process. By having very low levels of estrogen, the myostatin substance is free to suppress muscle growth which is something all fitness professionals want to avoid. 3. Low estrogen levels can worsen insulin resistance. Insulin, a substance produced by the pancreas, is essential for "unlocking" cells in the bloodstream, allowing them to absorb the existing glucose – a process which gives the human body energy to survive and to perform daily tasks. When cells develop insulin resistance (as a result of a sedentary lifestyle, among other factors), type 2 diabetes can result. Doctor Evelyn Yu, M.D., an endocrinologist at the Harvard University, concluded that estrogen deficiency could lead to a poor glycemic index as well as an increased resistance to insulin. Men and women of all ages can be affected by this, and that’s why it's important never to reduce the estrogen hormone to a dangerous level. Another study conducted on men aged 40-74 years determined the important role of high aromatase activity in the body. Let's take a closer look at its findings. High Aromatase Activity in Men with Low Testosterone Is Associated with Higher Spine BMD, Increased Truncal Fat Mass and Reduced Lean Mass Study Purpose This study strives to determine a relationship between spine BMD (bone mineral density) and aromatase activity in patients with low testosterone levels. Study Methods 90 men aged 40-74 years were carefully monitored during a genetic study on the effects of the aromatase enzyme on the bone mineral density. These men underwent testosterone replacement therapy as a result of low testosterone levels. Their body composition was analyzed using advanced tools such as dual-energy x-ray machines and enzyme immunoassay, among other medical equipment. Study Conclusions The study concluded that men who had the highest estradiol levels in comparison with testosterone also registered the highest spine bone mineral density. At the same time, their high aromatase activity leads to an increase in truncal fat as well as a significant decrease in lean body mass. The most important finding of this study is that despite having low circulating testosterone levels, high aromatase activity can lead to healthy musculoskeletal health in men over 40 years old. The direct relationship between estradiol and high bone density is visible in this study. Summary The role of estradiol in men's health cannot be denied. There are numerous benefits this hormone can provide to men of all ages if it circulates in the blood in optimal quantities. This article is part of a series of documents which outline important findings of scientific studies on estradiol. The more information one accumulates on estradiol, the better decisions he can make when it comes to achieving healthy estrogen levels in the body. One of the best ways to determine how much estradiol one has in his body is by using blood tests. This is an inexpensive and highly efficient method of knowing the exact estrogen and testosterone levels. Do you have any questions? Do you know more about estradiol or want to provide feedback?
