About FSH
Binds FSH receptors on Sertoli cells in testes to support sperm maturation and inhibin B production. In women, binds granulosa cell FSH receptors to drive follicular growth and estradiol production.
A pituitary gonadotropin essential for spermatogenesis in men and follicular development in women. Used in fertility treatment and studied for male hypogonadism, azoospermia, and ovarian stimulation protocols.

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.
