  • Does not provide protection against sexually transmitted infections

How the IUD is Used

The IUD is inserted in your uterus by your health care provider usually during or after menstruation (a period). It may stay in place from one to ten years depending on the type of IUD used. The IUD has a string that extends into the vagina. This string should be checked by the woman monthly after menstruation to make sure the IUD is in place.


You need to receive a complete gynecological exam every year. If you have any problems, contact your health care provider.
