Copper-T is an intrauterine device that some women use for birth control. It is a barrier. It is inserted high in the uterus by a physician, and provides enhanced contraceptive protection for up to ten years. Copper IUDs actually prevent fertilization by reducing the number and viability of sperms reaching the egg, and by impeding the number and movement of eggs into the uterus. It is believed that the continuous release of copper from the coils and sleeves of the Copper T 380A into the uterine cavity enhances the contraceptive effect of the IUD.
