Intrauterine device (IUD)

An intrauterine device (IUD) is a small plastic and copper T-shape, which is placed inside the uterus. The IUD was invented in the early 1950s, and has been improved over the years, although it is still not a method that all women like.

How the IUD works
The IUD prevents sperm from reaching an egg or an egg from settling into the lining of the uterus. The intrauterine device is as effective as the pill.
Some IUDs also release a small amount of hormones for extra safety.
