    GlossaryGonadotropin-Releasing Hormone Agonists (GnRH analogs)

    medications that initially boost, then suppress, sex hormone production

    Gonadotropin-Releasing Hormone Agonists (GnRH agonists) are medications that mimic the natural hormone GnRH, which regulates the release of other hormones like luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the pituitary gland. Initially, they increase the production of these hormones, but with continuous use, they suppress their release, leading to reduced levels of sex hormones such as testosterone and estrogen. This makes them useful in treating hormone-sensitive conditions like prostate cancer, endometriosis, and certain types of breast cancer.
