The Copper IUD (intrauterine device) is a small, T-shaped device made of plastic and copper that is inserted into the uterus by a healthcare provider. It is a long-acting form of contraception that can prevent pregnancy for up to 10 years. The copper wire around the device releases copper ions, which create an environment that is toxic to sperm, thus preventing fertilization. In addition to preventing pregnancy, the Copper IUD can also make menstrual periods heavier and more painful for some users. It does not contain hormones, making it a suitable option for those who prefer non-hormonal birth control methods. Regular check-ups with a healthcare provider are recommended to ensure proper placement and function.
