(HealthDay News) -- An intrauterine device (IUD) is a small T-shaped device that is placed in the uterus by a doctor. The cervix keeps it in place and, once it is in, you typically cannot feel it.
Depending on the type of IUD, it can work for 3 to 10 years, the U.S. Department of Health and Human Services says.
An IUD can be removed at any time and, once removed, your ability to get pregnant should go back to normal.
IUDs do not protect against sexually transmitted diseases.
