Deciding about an IUD

Contraception - IUD; Birth control - IUD; Intrauterine - deciding; Mirena - deciding; ParaGard - deciding

An intrauterine device (IUD) is a small, plastic, T-shaped device used for birth control. It is inserted into the uterus where it stays to prevent pregnancy.

Intrauterine device

The intrauterine device shown uses copper as the active contraceptive, others use progesterone in a plastic device. IUDs are very effective at preventing pregnancy (less than 2% chance per year for the progesterone IUD, less than 1% chance per year for the copper IUD). IUDs come with increased risk of ectopic pregnancy and perforation of the uterus and do not protect against sexually transmitted disease. IUDs are prescribed and placed by health care providers.
