IUD Progesterone. An Intra-Uterine Device (IUD) is a small, flexible, plastic device placed inside a womanâs uterus. Mirena is the brand-name for a type of IUD that releases synthetic progesterone hormone into a womanâs body. The IUD makes it harder for sperm and eggs to move, or for a fertilized egg to lodge in the uterus. It is 99.8% effective in preventing pregnancy, making it slightly more effective than sterilization.
It depends on the kind of IUD you have. One IUD, the levonorgestrel IUD (Mirena), can stay in your uterus for up to 5 years, and the newest one, (SkylaÂ®) works for up to 3 years. Copper IUDs can stay in your uterus for up to 10 years. You can get the IUD removed by your health care provider at any time. A new IUD can be inserted at the time of the removal. As soon as the IUD is removed, you can get pregnant.
