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.
