LH (Luteinizing Hormone)
LH is a pituitary hormone that triggers ovulation in women and stimulates testosterone production by Leydig cells in men. The mid-cycle LH surge drives ovulation, and persistent elevation of LH relative to FSH can suggest polycystic ovary syndrome. Elevated LH in postmenopausal women reflects ovarian failure, while low LH suggests hypothalamic or pituitary dysfunction.
