Patient's question:
NoDoctor's answer:
An intrauterine device (IUD) is a form of intrauterine contraception that can prevent pregnancy. It is very commonly used. This can be removed, but if left in for a long time, such as decades, it may grow together with the tissue and cannot be removed. After removal, pregnancy is possible, but it does affect menstruation. It is not a completely side-effect-free method.
