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.
The IUD is a little, t-shaped piece of plastic that gets put in your uterus to mess with the way sperm can move and prevent them from fertilizing an egg. Sounds odd, but it works like a charm. IUDs offer years of protectionâbetween three and twelve, depending on the type you get. And if you want to get pregnant, you can have the IUD removed at any time. In the U.S. there are five IUDs: Mirena, ParaGard, Skyla, Liletta, and Kyleena.
