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.
Side effects of the IUD include spotting, infection, infertility, pelvic inflammatory disease, and heavy menstrual bleeding. Risks and complications of the IUD are miscarriage, ectopic pregnancy, pelvic inflammatory disease, and increased menstrual bleeding.
