It is synthesised and secreted by the gonadotropic cells located in the anterior pituitary gland. LH is classified as a gonadotropin, meaning it acts on the gonads (testes in males and ovaries in females) to regulate reproductive functions. A luteinizing hormone (LH) test is a blood or urine test that measures the levels of LH in a person's blood. This hormone plays a key role in the reproductive system of both males and females.
