Luteinizing Hormone (LH)

Luteinizing Hormone (LH) is a crucial hormone produced by the pituitary gland, playing a key role in regulating the reproductive system. In females, LH triggers ovulation and supports the production of progesterone, essential for maintaining pregnancy. In males, it stimulates testosterone production, which is vital for sperm production and overall reproductive health.

An LH test is commonly conducted to diagnose conditions such as polycystic ovary syndrome (PCOS), irregular menstrual cycles, and infertility in women. In men, it helps assess testicular function and low testosterone levels. The test is also useful in diagnosing pituitary disorders that may impact hormone production.

Abnormal LH levels can indicate various health concerns. High levels in women may suggest menopause, ovarian failure, or PCOS, while low levels may indicate pituitary gland dysfunction. In men, low LH can be associated with testosterone deficiency, affecting fertility and overall well-being.

Doctors often recommend LH tests alongside follicle-stimulating hormone (FSH) and testosterone or estrogen tests to get a complete picture of hormonal balance. The test involves a simple blood sample and is usually conducted on specific days of the menstrual cycle for women. Early detection of hormonal imbalances can aid in timely medical intervention and better reproductive health management.
