IUD contraceptive. This intrauterine device (IUD),or coil,is composed of plastic and copper. It is inserted through the cervix,into the womb to prevent pregnancy. It is thought to work by inhibiting the implantation of a fertilised egg. IUDs are not as effective as the pill. IUDs that contain copper need to be changed every 3 to 5 years | |
