The letters IUD stand for “intrauterine device.” IUDs are small, “T-shaped” devices made of flexible plastic. A health care provider inserts an IUD into a woman’s uterus to prevent pregnancy. There are two brands of IUD available in the United States — ParaGard and Mirena. The ParaGard IUD contains copper. It is effective for 12 years. The Mirena IUD releases a small amount of progestin, a hormone. It is effective for five years. Both the ParaGard and the Mirena IUDs work mainly by affecting the way sperm move so they can’t join with an egg. If sperm cannot join with an egg, pregnancy cannot happen. For some women, Mirena may prevent the egg from leaving the ovary. Pregnancy cannot happen if there is no egg to join with sperm. Progestin also prevents pregnancy by thickening a woman’s cervical mucus. The mucus blocks sperm and keeps it from joining with an egg.
