Contraception

Intrauterine devices (IUDs), explained

An intrauterine device (IUD) is a small device placed inside the uterus for contraception. It's a long-acting, reversible option and one of the most reliable methods available.

This page explains the types of IUD and what having one involves.

Key points

  • An IUD is a small device placed in the uterus.
  • There are hormonal and copper (hormone-free) types.
  • IUDs are long-acting and among the most reliable options.
  • They're reversible, fertility returns after removal.

The two main types

There are two broad types, and a clinician can help you decide which suits you.

  • Hormonal IUDs, which release a small amount of progestogen
  • Copper IUDs, which are hormone-free

What to expect

An IUD is inserted by a trained clinician during a short procedure. Some people have cramping around insertion. Once in place, an IUD works for several years, depending on the type, and can be removed earlier if you wish.

Reversibility

IUDs are fully reversible. Fertility generally returns after removal, which is why they suit people spacing pregnancies as well as those wanting long-term contraception.

When to see a specialist

If you're considering an IUD, a clinician can talk through the types, whether one suits you, and what insertion involves.
