An IUD, or intrauterine device, is a small, plastic, flexible, T-shaped device that is placed into a woman’s uterus for birth control. There are two types of intrauterine device’s available in the United States. One is hormonal, and one is not. An Intrauterine device is 98% – 99% effective for birth control.
The hormonal IUD releases progestin, which causes the cervical mucus to become thicker so sperm cannot reach the egg. The hormone also changes the lining of the uterus, so implantation of a fertilized egg cannot occur. There are two types of hormonal IUDs available: Mirena & Skyla. Mirena can be used for 5 years, and Skyla can be used for 3 years.
The non-hormonal intrauterine device contains copper. The copper is slowly released into the uterine cavity. It stops the sperm from making it through the vagina and uterus to reach the egg, thus preventing fertilization. There is only one non-hormonal intrauterine device available, ParaGard. It can be kept in place for up to 10 years.
