Cetrorelix acetate is primarily used in the field of reproductive medicine as a gonadotropin-releasing hormone (GnRH) antagonist. It is administered to prevent premature ovulation in women undergoing controlled ovarian stimulation for assisted reproductive technologies, such as in vitro fertilization (IVF). By inhibiting the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), it helps to control the timing of egg maturation and retrieval, improving the chances of successful fertilization. Additionally, it is sometimes used in the treatment of hormone-dependent conditions, such as endometriosis or uterine fibroids, by suppressing the production of sex hormones. Its application ensures better management of fertility treatments and hormonal disorders.
