The coil, also known as an intrauterine device (IUD), is a small T-shaped device that is inserted into the uterus to prevent pregnancy. There are two main types of coils: hormonal coils, which release a small amount of progestin to prevent pregnancy, and copper coils, which work by creating an inflammatory reaction that is toxic to sperm. Both types of coils are highly effective at preventing pregnancy and can last for several years before needing to be replaced. It's important to consult with a healthcare provider to determine which type of coil is best for you and to discuss any potential side effects or risks. **
