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 copper IUD. The copper IUD is a small plastic device with copper wire wrapped around it and a fine nylon string attached to the end. When the IUD is in place, the string comes out through the cervix into the top of the vagina. The hormonal (Mirena) IUD. The hormonal (Mirena) IUD is a small plastic âT-shapedâ device that contains progestogen. This is a synthetic version of the natural hormone progesterone. The device has a coating (membrane) that controls the release of the progestogen into the uterus. Like the copper IUD, it has a fine nylon string attached to the end to make checking and removing it easier. The hormonal IUD is available in Australia under the brand name Mirena.
