The intrauterine device (IUD), is a birth control device placed into a woman’s uterus by a health care provider. It is usually made of plastic or metal with a string attached.There are 2 types of IUDs. The devices that contain copper can stay in the uterus for up to 10 years. IUDs that contain the female hormone progesterone can stay in place up to 5 years. The IUD prevents pregnancy by changing the physical environment of the reproductive tract. These changes appear to prevent the egg from being fertilized or implanting and growing in the uterus. Ask your provider for more information about the IUD or you may visit their websites and/or ask for their patient brochures at your next visit to our office. Also, contact your insurance company to obtain payment information and ask about any potential authorization requirements. Our office offers the following IUDs: Mirena, Skyla, Kyleena, Liletta and the hormone free Paragard.
