luteinizing hormone
controls production of testosterone by interstitial cells
Luteinizing hormone (LH) is a hormone that is produced and secreted by the anterior pituitary gland. It plays a crucial role in the regulation of the reproductive system in both males and females. In women, LH is responsible for triggering ovulation and the development of the corpus luteum after ovulation to produce progesterone. In men, LH stimulates the production of testosterone by the testes.
LH is regulated by a hormone called gonadotropin-releasing hormone (GnRH) that is released by the hypothalamus in the brain. GnRH stimulates the anterior pituitary gland to release LH and follicle-stimulating hormone (FSH). LH levels are highest in the middle of the menstrual cycle in women, just prior to ovulation. In men, LH levels remain relatively constant, but can be affected by conditions such as hypogonadism, a condition where the testes do not produce enough testosterone.
LH levels can be tested through a blood test, which is often used to diagnose and monitor conditions affecting the reproductive system, such as infertility, PCOS (polycystic ovary syndrome), and pituitary disorders.
In summary, LH plays a critical role in the regulation of the reproductive system in both men and women, stimulating the production of testosterone in men and triggering ovulation in women. It is regulated by the hypothalamus and can be tested through a blood test to identify potential issues.
