An intrauterine device (IUD), also known as intrauterine contraceptive device or coil, is a small, often T-shaped birth control device that is inserted into the uterus to prevent pregnancy. IUDs are one form of long-acting reversible birth control (LARC). One study found that female family planning providers choose LARC methods more often (41.7%) than the general public (12.1%). Among birth control methods, IUDs, along with other contraceptive implants, result in the greatest satisfaction among users.
