Luteinizing Hormone

Luteinizing Hormone (LH) is a hormone produced by the anterior pituitary gland that plays a key role in reproductive health for both men and women. In women, LH triggers ovulation and supports the menstrual cycle by stimulating progesterone production. In men, it promotes testosterone production in the testes. Maintaining balanced LH levels is important for proper hormonal regulation and reproductive function.
