Urofollitropin For Injection BP is a medication used in assisted reproductive technology (ART) to stimulate the development of multiple eggs (follicles) in the ovaries. Urofollitropin is a purified form of follicle-stimulating hormone (FSH), which is a hormone naturally produced by the pituitary gland in the brain. In ART, urofollitropin is used to help women who are undergoing fertility treatments, such as in vitro fertilization (IVF) or intrauterine insemination (IUI), to increase the number of mature eggs available for fertilization. Urofollitropin For Injection BP is usually used in combination with other fertility medications, such as human chorionic gonadotropin (hCG), to trigger ovulation and prepare for egg retrieval or insemination.
