Detailed Description
The Luteinizing Hormone (LH) Serum Test is a vital diagnostic investigation used to evaluate reproductive health and hormonal balance in both men and women. LH is a key hormone produced by the pituitary gland that plays a crucial role in ovulation in females and testosterone production in males. This test helps in assessing fertility status, menstrual irregularities, and endocrine disorders.
About the Test & Biomarker
Luteinizing Hormone (LH) works in coordination with Follicle-Stimulating Hormone (FSH) to regulate the reproductive system. In women, LH surge triggers ovulation, while in men it stimulates the testes to produce testosterone. Abnormal LH levels may indicate hormonal imbalances, pituitary disorders, or reproductive health issues.
