Intrauterine devices (IUDs) are a type of long-acting reversible contraception that are inserted into the uterus to prevent pregnancy. There are two types of IUDs available: hormonal and non-hormonal.
Hormonal IUDs contain a small amount of progestin, which thickens cervical mucus and thins the lining of the uterus to prevent sperm from reaching and fertilizing an egg. This type of IUD can be effective for up to 3-5 years, depending on the brand.
Non-hormonal IUDs are made of copper, which is toxic to sperm and prevents fertilization. This type of IUD can be effective for up to 10 years.
IUDs are inserted into the uterus by a healthcare provider and can be removed at any time. The insertion procedure can be uncomfortable for some people, but is generally quick and safe.
IUDs are highly effective at preventing pregnancy, with a failure rate of less than 1%. They are also a convenient form of birth control, as they do not require daily or weekly maintenance like other methods.
However, it is important to note that IUDs do not protect against sexually transmitted infections and may have potential side effects such as irregular bleeding and cramping. It is important to talk to a healthcare provider to determine if an IUD is the right choice for your individual needs and circumstances.
