Overview

ParaGard is an intrauterine device (IUD) that can provide long-term birth control (contraception). It's sometimes referred to as a nonhormonal IUD option.

The ParaGard device is a T-shaped plastic frame that's inserted into the uterus. Copper wire coiled around the device produces an inflammatory reaction that is toxic to sperm and eggs (ova), preventing pregnancy.

ParaGard is the only copper IUD available in the United States. It can prevent pregnancy for up to 10 years after insertion.
