Follitropin alfa is a hormone identical to follicle-stimulating hormone (FSH) produced by the pituitary gland. FSH helps to develop eggs in the ovaries. Follitropin alfa is used as a fertility medicine to develop eggs in women who have not been able to become pregnant because of problems in ovulation. Also, many women wanting to become pregnant will use this medicine while enrolled in a fertility program (assisted reproductive technology [ART]) that uses procedures such as in vitro fertilization (IVF) or embryo transfer (ET). Follitropin alfa may be used with other medicines for these purposes.
