… In other words, how long until the IUD is effective?
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.
