I don't know where you learnt that but it's just not true. Look on the planned parenthood website that dru and I linked. The IUD prevents (not terminates) pregnancy by stopping the sperm from joining up with the egg. It does this b thickening he cervical mucus so they can't move. Mirena also stops some women releasing an egg at all. Although this isn't necessary as the egg can't be fertilised either way. An IUD is one of the most effective forms of birth control with less than 1% of women getting pregnant on it.
