The letters "IUD" stand for "intrauterine device." The IUD is a safe and highly effective form of long-acting reversible contraception (LARC). IUDs are small, "T-shaped" contraceptive devices made of flexible plastic. IUDs are inserted into the uterus by a medical provider with special training.
There are currently 3 types of IUDs available on the United States; The Paragard (a plastic T wrapped with copper wire which can be left in place for up to 12 years), the Mirena (a plastic T which releases the hormone progesterone and can be left in place for up to 5 years), and the Skyla (like the Mirena but a little smaller and can be left in place for up to 3 years. The Skyla is designed for insertion in younger people and those who have never given birth, but can be used in any person with a uterus.)
The IUD is the reversible contraceptive method used by more women across the globe.
