Leutinizing Hormone (LH) Test

The Leutinizing Hormone (LH) Test is used to measure the amount of LH hormone present in the blood. LH is an essential hormone produced by the pituitary gland and plays a key role in regulating the reproductive system in both men and women.

In women, LH controls:

• Menstrual cycle regulation

• Ovulation (release of egg)

• Formation of the corpus luteum

• Estrogen and progesterone balance

A sudden increase in LH levels, known as the LH surge, triggers ovulation. Abnormal LH levels may indicate:

• Polycystic Ovary Syndrome (PCOS)

• Ovarian failure

• Infertility

• Pituitary disorders

In men, LH stimulates the production of testosterone in the testes, which is essential for:

• Sperm production

• Sex drive

• Muscle mass and bone strength

• Male sexual development

Low LH levels may indicate pituitary gland disorders, while high LH levels may point toward testicular failure or hormonal imbalance. The LH test is widely used for fertility evaluation, puberty disorders, and endocrine system assessment.

This is a serum blood hormone test used to measure the Leutinizing Hormone (LH) produced by the pituitary gland.
