Urofollitropin

Urofollitropin (brand names Bravelle®, Fertinex®, Follistim®, and Gonal-F®)is a purified form of follicle-stimulating hormone (FSH). FSH is important in the development of follicles (eggs) produced by the ovaries. Given by subcutaneous injection, it is used in combination with human chorionic gonadotropin (hCG) to assist in ovulation and fertility. It is also used with in vitro fertilization methods. The dosage is adjusted to each individual's response.

Its side effects include breast tenderness, mild diarrhea, nausea, or vomiting.
