An intrauterine device or IUD is a tiny, T-shaped birth control device. It is basically a plastic device, which is wrapped in copper. It also contains certain hormones. An IUD is inserted into the uterus by a doctor. There is a plastic string tied to the end of the IUD and it hangs down through the cervix into the vagina. To ensure that the IUD is in place, one can feel for this string through the vagina.
