IUD / Intra-Uterine Device / Coil

This is a small plastic/copper device with strings that is inserted into the womb. It prevents sperm from meeting the eggs and stops an egg settling in the womb. It can stay in place for five years with a success rate of 98%.

Advantages - doesn't interrupt sex. Stays in for around five years.

Disadvantages - periods may be heavier or longer so it is not suitable for women suffering from heavy periods. It's best for women in a faithful relationship because of the risk of pelvic infection.
