Expert
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.
