The copper IUD is a long-term, non-hormonal birth control method that is more than 99% effective at preventing pregnancy. It is a small, T-shaped device that is inserted into the uterus by a healthcare provider. The copper in the IUD creates an inflammatory reaction that makes it difficult for sperm to survive and fertilize an egg. The copper IUD is a great option for people who want a reliable and effective birth control method without having to use hormones. It is also a good choice for people who want a long-term birth control method that they don’t have to think about every day.
