IUD

The letters IUD stand for "intrauterine device." IUDs are small, "T-shaped" devices made of flexible plastic. Our clinician will insert 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, and is effective for 12 years. The Mirena IUD releases a small amount of progestin, a hormone, and is effective for five years. Both the ParaGard and the Mirena IUDs affect the way sperm move, preventing them from joining with an egg. If sperm cannot join with an egg, pregnancy cannot happen.
