ID: ANH14130S110

MEDICAL ANIMATION TRANSCRIPT: An intrauterine device, or IUD, is one of the most effective methods of birth control. IUDs are over 99% effective at preventing pregnancy. This means that less than one out of 100 women will become pregnant each year if they use an IUD and check it regularly for correct placement. However, IUDs are only about 97% effective if not checked for correct placement.
