This panel includes: Total and Free Testosterone (LC/MS), Luteinizing Hormone (LH), and Follicle Stimulating Hormone (FSH) at substantial savings that buying each test separately.

This panel includes: Testosterone, Total, LC/MS and Free (Equilibrium Dialysis), and 17-OH-progesterone, a metabolite that has been correlated with sperm production.

Testosterone Replacement Therapy (TRT) shuts down upstream hormones like LH and FSH required for sperm production, so men on TRT generally have a difficult time fathering a child. Some studies show that adding hCG to a TRT protocol may improve sperm production since hCG is an analog of LH that could stimulate sperm production. But optimizing hCG dose and frequency based on sperm count can be a time consuming process since it takes at least 8 weeks to see changes in sperm tests. Fortunately, there is an easier way by measuring 17-OH-progesterone to predict the efficacy of the hCG+TRT protocol without having to wait for 8 weeks between hCG dose/frequency changes. 

The most economical lab test panel with 4 tests for men on TRT:

1. Total Testosterone, Liquid Chromatography/ Mass Spectrometry
2. Free Testosterone, Equilibrium Dialysis
3. Ultrasensitive Estradiol, Liquid Chromatography/ Mass Spectrometry
4. Hematocrit

The most complete of all blood test panels for men that include: Total and Free Testosterone, Ultra Sensitive Estradiol, IGF-1, Prolactin, DHT, DHEA-S, PSA, SHBG, Lipids, CBC, CMP, and Thyroid Function (TSH, Free T3, Free T4).
