An intrauterine device (IUD) is a contraceptive that is inserted by a doctor into the uterus. It is ideal if you want a low maintenance contraceptive. It's a fit-and-forget contraceptive, which means you do not have to remember to use it regularly like condoms or the pill.
There are two types of IUDs: the copper IUDs (also known as copper coils) and hormone IUDs (also known as intrauterine system or IUS).
Hormone IUDs include the Mirena, which lasts about 5 years, and Jaydess, which lasts about 3 years. Jaydess is used in women who have never given birth before.
The hormone IUD has a small reservoir containing the hormone levonorgestrel, which prevents you from getting pregnant. They do not contain oestrogen.
Copper coils include the Flexi T and Eurogine, which last about 5 years, and the Monalisa which lasts about 10 years.
Copper coils have a copper wire wound tightly around the device's stem and do not contain hormones. This makes them popular among women who cannot take hormones due to medical conditions or side effects.
All types of IUD provide 99% protection against pregnancy when fitted correctly. The hormone based coils also used to treat certain gynaecological problems like heavy periods.
