The IUD or intrauterine devicerefers to the piece of plastic coated with the copper which is inserted in the uterus by the doctor. Copper is gradually released (IUD generally last 5 to 10 years) and as it has a spermicidal action the sperm cells are destroyed before fecundation takes place. In this mechanism, the movement of IUD within the uterus causes slight endometrial inflammation which helps to avoid nidation.
