Urofollitropin is a purified form of follicle-stimulating hormone (FSH) that is manufactured by extraction from human urine and then purified[1] to remove various proteins and other substances. 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.[2] It is also used with in vitro fertilization methods. The dosage is adjusted to each individual's response.[2]
The most common side effects are abdominal or pelvic pain, bloating, as well as redness, pain or swelling at the injection site. Follitropin is possibly associated with increased risk of endometrial carcinoma. It is not for use during pregnancy, as there is evidence for birth defects under follitropin treatment.[2]
