Luteinizing Hormone-Releasing Hormone (LHRH), also known as gonadotropin-releasing hormone (GnRH), is a hormone produced in the hypothalamus of the brain. It plays a crucial role in regulating the reproductive system by stimulating the pituitary gland to release luteinizing hormone (LH) and follicle-stimulating hormone (FSH). These hormones are essential for the development of eggs in ovaries and sperm in testes. LHRH is released in a pulsatile manner, meaning it is secreted in bursts rather than continuously. This pattern is important for maintaining proper reproductive function. Abnormal levels of LHRH can lead to various reproductive disorders, affecting fertility and hormonal balance in both males and females.
