How does Follistim® AQ Cartridge (follitropin beta injection) work?
Follistim® AQ Cartridge (follitropin beta injection) acts like naturally produced follicle-stimulating hormone (FSH), the hormone that stimulates the ovaries. It binds to the surface of the immature follicle to trigger a series of events that lead to the growth of the follicle and the maturation of the egg. Follistim® AQ Cartridge (follitropin beta injection) (or other drugs containing FSH) will not induce ovulation. For ovulation to occur, a second hormone called human chorionic gonadotropin, available as Pregnyl® (chorionic gonadotropin for injection, USP), is administered.
