How Does It Work?
Unlike many other forms of birth control, the copper IUD does not contain any hormones. It is inserted into the uterus by your healthcare provider, where it can remain for up to 10 years; some healthcare providers are comfortable leaving it in place for up to 12 years.
It is not exactly clear how the copper IUD works to prevent pregnancy. It has been suggested that the IUD may interfere with the sperm's ability to reach the egg, block fertilization of the egg, or prevent implantation of an embryo.
