About hCG
Glycoprotein hormone binding LH receptor on Leydig cells; stimulates testosterone production; prevents testicular atrophy during TRT; maintains spermatogenesis via FSH-like activity
The most widely used adjunct in testosterone replacement therapy. Maintains testicular size and function, preserves fertility, and stimulates endogenous testosterone production by mimicking LH.

About Leuprolide
Continuous GnRH receptor stimulation causes receptor desensitization and downregulation. This suppresses LH/FSH → testosterone/estrogen to castrate levels. Short-term pulsatile use can transiently stimulate the axis before suppression occurs.
A synthetic GnRH agonist that paradoxically suppresses gonadotropin release with continuous administration via receptor downregulation. FDA-approved for prostate cancer, endometriosis, and uterine fibroids. Used off-label in men's health for HPG axis restart protocols.
