What type of contraception is an intrauterine device (IUD)?

An intrauterine device (IUD) is classified as long-acting reversible contraception (LARC) due to its design and functionality. LARCs are methods of birth control that provide effective contraception over an extended period without requiring daily attention, making them highly convenient for users.

IUDs, both hormonal and non-hormonal (copper), can remain effective for several years after placement, providing reliable pregnancy prevention for the duration of their use. Unlike barrier methods, which physically block sperm from reaching the egg, or hormonal methods that rely on the regular intake of hormones to regulate the menstrual cycle, IUDs maintain their effectiveness passively and can be removed at any time by a healthcare provider, allowing for a quick return to fertility.

Permanent methods, such as sterilization, are not reversible and do not fall under the classification of LARC. Therefore, the attribution of IUDs to long-acting reversible contraception aptly highlights their effectiveness and flexibility in family planning.
