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.

About Gonadorelin

Synthetic GnRH that binds pituitary GnRH receptors; pulsatile dosing stimulates LH/FSH release; used to maintain HPG axis during TRT
