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 Kisspeptin-54
Full-length kisspeptin (54 amino acids); binds KISS1R on GnRH neurons with higher receptor occupancy and longer duration than KP-10; induces more sustained GnRH/LH pulses
