Gonadotropin-releasing hormone (GnRH) agonists are a class of medications used in the treatment of various hormonal conditions such as infertility, endometriosis, and certain types of cancer. These medications work by binding to and activating the GnRH receptors in the pituitary gland, which results in the suppression of the production of certain hormones such as luteinizing hormone (LH) and follicle-stimulating hormone (FSH). This suppression can help regulate hormonal imbalances and control the growth of certain hormone-dependent tumors. GnRH agonists are commonly used in combination with other treatments to manage hormonal conditions effectively.
