The Luteinizing Hormone (LH) Test is a blood test that measures the level of LH, a hormone produced by the pituitary gland that plays a key role in regulating the reproductive system.

In women, LH is responsible for triggering ovulation and supporting the menstrual cycle. In men, LH stimulates the production of testosterone in the testes. Abnormal LH levels may indicate conditions such as infertility, polycystic ovary syndrome (PCOS), pituitary disorders, or hormonal imbalances.

This test is commonly used in fertility evaluations, assessment of menstrual irregularities, and diagnosis of endocrine disorders. It is often performed along with other hormone tests such as FSH, estrogen, or testosterone for a comprehensive evaluation.

The purpose of this test is to:

• Measure LH levels in the blood
• Assess ovulation and menstrual cycle function
• Evaluate fertility and reproductive health
• Diagnose hormonal and pituitary disorders
