Full Form of LH

What is LH?

Luteinizing Hormone (LH) is a glycoprotein hormone secreted by the anterior pituitary gland. In both males and females, it plays a pivotal role in the reproductive system. In women, LH triggers ovulation and supports the production of estrogen and progesterone; in men, it stimulates testosterone production from Leydig cells in the testes. In India, LH levels are commonly measured through blood tests to assess fertility issues, menstrual irregularities, and conditions such as polycystic ovary syndrome (PCOS) or hypogonadism. These tests are widely available in diagnostic labs across urban and rural areas. LH is also tested as part of routine hormonal panels for couples undergoing assisted reproductive technologies like IVF. For students preparing for medical entrance exams such as NEET or nursing exams, understanding LH's function and regulation by gonadotropin-releasing hormone (GnRH) is essential. The hormone's cyclical pattern during the menstrual month is a key concept in reproductive physiology. Clinicians use LH surge detection kits for timing ovulation, making it a practical tool for family planning. Overall, LH is a cornerstone hormone in endocrinology and reproductive medicine.
