An intrauterine device (intra meaning within, and uterine meaning of the uterus) is a birth control device also known as an IUD or a coil (this colloquialism is based on the coil-shaped design of early IUDs). It is a device placed in the uterus and is the world's most widely used method of reversible birth control. The device has to be fitted inside or removed from the uterus by a doctor or qualified medical practitioner. It remains in place the entire time contraception is desired. Depending on the type, a single IUD may be used for 5 to 10 years.

Types of IUDs

---

Availability of IUDs varies widely by country. Only one brand (Paragard T 380A), for example, is available in the United States, while seven brands (Flexi-T 300, GyneFix - also called FlexiGard 330 or CuFix PP330, Multi-Safe 375, Multi-Load Cu 375, Neo-Safe T380, Nova T 380, T-Safe 380A) are available in Great Britain. There are also hormonal devices that are placed in the uterus (IntraUterine System).

Most types of IUDs have a plastic T-shaped frame that is wrapped with copper and/or has copper bands. Some IUDs, such as the Nova T 380, also contain a small amount of silver. The arms of the frame hold the IUD in place near the top of the uterus. The GyneFix does not have a T-shape, but rather is a loop that holds several copper tubes. The GyneFix is held in place by a suture to the fundus of the uterus.
