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.
Testing LH levels can benefit individuals facing fertility issues, irregular menstrual cycles, or symptoms of hormonal imbalances. It’s also helpful for those undergoing fertility treatments or suspecting conditions like polycystic ovary syndrome (PCOS) in women or low testosterone levels in men.

Low LH:
Yes, elevated LH levels can be an indicator of menopause or perimenopause, as the body tries to stimulate the ovaries which are less responsive.
In women, LH surges mid-cycle to trigger ovulation, releasing an egg from the ovary, and is crucial for maintaining the menstrual cycle’s regularity.
