Female Hormone Test List

Essential Female Hormone Test List

What are the common hormones included in a female hormone test?

Common hormones included in a female hormone test are estrogen, progesterone, testosterone, follicle-stimulating hormone (FSH), luteinizing hormone (LH), and thyroid hormones like T3 and T4. These hormones play crucial roles in regulating female reproductive health, menstrual cycles, and overall well-being.

Hormones play a pivotal role in regulating numerous biological processes in women, including reproductive health, mood swings, and metabolism. As such, hormonal imbalances can lead to a myriad of health issues, from infertility and menstrual irregularities to thyroid disease and other disorders. In this comprehensive guide, we delve into the key hormone tests essential for diagnosing and managing various endocrine and reproductive health concerns. We'll also discuss how testosterone fits into the hormonal landscape for women.

Testosterone's Understated Importance for Women

Contrary to popular belief, testosterone is not exclusively a "male hormone." It plays a significant role in women's health too, impacting libido, mood, and even bone health. While it's not typically included in the standard array of female hormone tests, understanding its levels and its impact on sex drive can offer a more comprehensive overview of a woman's hormonal profile.

Follicle-Stimulating Hormone (FSH) Test

The anterior pituitary gland produces the hormone FSH, which controls ovarian follicle growth and maturation in women. An FSH test gauges the concentration of this hormone in the bloodstream, offering key insights into conditions like menstrual abnormalities, infertility, Polycystic Ovary Syndrome (PCOS), premature ovarian failure, and menopause. FSH concentrations oscillate throughout the menstrual cycle, peaking in the early follicular phase at high levels.

Luteinizing Hormone (LH) Test

Luteinizing hormone (LH) is another important hormone that the anterior pituitary gland produces. This hormone is instrumental in inducing ovulation and encouraging progesterone production by the corpus luteum. Like FSH, LH levels vary across the menstrual cycle, with a mid-cycle surge triggering ovulation. An LH test can help diagnose menstrual disorders, infertility, PCOS, and pituitary gland anomalies, making it an essential part of testing for the main sex hormones in women, including the pregnancy test.

Estradiol (E2) Test

Estradiol is the main estrogen hormone and is very important for the development of a woman's reproductive organs, secondary sexual traits, and the timing of her periods. An Estradiol test quantifies this hormone in the blood, aiding in the diagnosis of menstrual disorders, menopause, infertility, and ovarian cysts. Levels of estradiol, also known as estrogen levels, also fluctuate throughout the menstrual cycle, peaking just before ovulation and playing a crucial role in regulating various physiological and psychological functions such as bone density, brain function, cardiovascular system, central nervous system, and immune system.

Progesterone Test

Produced post-ovulation by the corpus luteum and during pregnancy by the placenta, progesterone prepares the uterine lining for a potential pregnancy. A Progesterone test is essential for assessing ovulation, menstrual irregularities, infertility, and complications in early pregnancy. The hormone's levels rise after ovulation and stay elevated throughout the luteal phase.

Prolactin Test

Another hormone that the anterior pituitary gland secretes is prolactin, which primarily controls lactation after childbirth. A prolactin test helps in diagnosing conditions like hyperprolactinemia, which can result in menstrual irregularities, infertility, and inappropriate lactation (galactorrhea). Elevated levels may also suggest the presence of a pituitary tumor, known as a prolactinoma.

Anti-Müllerian Hormone (AMH) Test

The granulosa cells of ovarian follicles produce AMH, which is a reliable indicator of ovarian reserve. This test can assess a woman's fertility potential, help diagnose PCOS, and predict menopausal onset. Unlike other hormones, AMH levels remain relatively consistent throughout the menstrual cycle.

Thyroid Function Tests (TFTs)

Thyroid hormones, including T4 and T3, impact various physiological functions, including reproductive health. TFTs measure thyroid stimulating hormone (TSH), free T4, and free T3 levels to diagnose and manage thyroid disorders that can affect fertility and menstrual health. These tests are invaluable for individuals experiencing menstrual irregularities, infertility, and pregnancy complications due to thyroid imbalances. Additionally, thyroid tests can also include thyroid antibodies such as thyroglobulin and thyroid peroxidase, which can help diagnose autoimmune thyroid disorders. Understanding the role of thyroid hormones and the importance of thyroid stimulating hormone (TSH) tests is crucial for maintaining overall hormonal balance and reproductive health.

   • A meta-analysis and a Position Statement on testosterone therapy for hypoactive sexual desire disorder in menopausal women have begun to close the gender gap. Testosterone deficiency and replacement in women are still debated, but non-oral short-term testosterone therapy has been shown to be effective and safe for postmenopausal women with hypoactive sexual desire disorder¹.
