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 females and sperm in males. LHRH is released in a pulsatile manner, meaning it is secreted in bursts rather than continuously. This pattern is important for maintaining proper hormonal balance and reproductive function. Abnormal levels of LHRH can lead to various reproductive disorders, affecting fertility and overall health.
