Intrauterine Device

Picture of an intrauterine device (IUD)

An intrauterine device (IUD) is a small, plastic, T-shaped device that is inserted into the uterus to prevent pregnancy. IUDs contain copper or the hormone levonorgestrel (LNg). Plastic strings tied to the end of the IUD hang down through the opening of the uterus (cervix) into the vagina.
