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.
Research Areas
About LH
Binds LH receptors on testicular Leydig cells, stimulating the cholesterol → testosterone biosynthetic pathway. In women, the LH surge triggers ovulation and supports luteal phase progesterone production.
A pituitary gonadotropin that drives testosterone production in men by stimulating Leydig cells, and triggers ovulation in women. Used in fertility protocols and studied for natural HPG axis support alongside FSH and hCG.
