IUDs (Intrauterine Devices) are long term, reversible methods of birth control used to effectively reduce the risk of pregnancy. An IUD is a T-shaped device that rests in the uterus. There are two types of IUDs: Hormonal & Non hormonal. The Hormonal IUD works by releasing hormones to prevent ovulation – the process where the ovaries release an egg – and thickening the cervical mucus. The Hormonal IUD is 99% effective in reducing the risk of pregnancy and lasts up to 3 or 5 years! Non Hormonal IUDs are made of copper which makes it hard for sperm to survive. The Non Hormonal IUD contains no hormones, but is also 99% effective in preventing pregnancy for up to 10 years.
The Non Hormonal IUD is effective right away, however, all hormonal forms of birth control (including the Hormonal IUD) take 1 week before they become effective. During this 1 week a person should use a backup method like abstinence or condoms.
Remember, IUDs do not reduce the risk of STIs. Only condoms and dental dams reduce the risk of STIs.
