IUD Fitting
An IUD or IUS (coil) is a small device placed in the womb for long-term contraception, and some types also treat heavy periods.
Quick answer
IUD Fitting: what it is, why it's done and what happens
An intrauterine device (IUD, copper coil) or intrauterine system (IUS, hormonal coil) is a small T-shaped device inserted into the womb. The copper type works without hormones; the hormonal type releases a small amount of progestogen.
- Why it is done: It is used for effective, long-acting, reversible contraception.
- What happens: In a clinic, the device is passed through the cervix into the womb using a thin applicator.
What it is
An intrauterine device (IUD, copper coil) or intrauterine system (IUS, hormonal coil) is a small T-shaped device inserted into the womb. The copper type works without hormones; the hormonal type releases a small amount of progestogen.
Why it is done
It is used for effective, long-acting, reversible contraception. The hormonal IUS is also used to treat heavy periods, and the copper IUD can be used as emergency contraception.
What happens
In a clinic, the device is passed through the cervix into the womb using a thin applicator. It usually takes a few minutes and can cause cramping. No anaesthetic is normally needed.
Recovery
Cramping and spotting are common for a few days to weeks. Bleeding patterns often change — periods may be lighter with the hormonal type or heavier at first with the copper type. Threads are checked periodically.

Risks and things to consider
Risks are small and include pain during fitting, infection in the first weeks, the device coming out, and rarely a small hole in the womb. It does not protect against sexually transmitted infections.

Answers
IUD Fitting: frequently asked questions
How long does a coil last?
Depending on the type, IUDs and IUS devices last several years (often 3 to 10), after which they are removed or replaced. They can be taken out earlier if you wish, with fertility returning quickly.
Does having a coil fitted hurt?
Many people feel cramping similar to period pain during and shortly after fitting. Pain varies; you can take pain relief beforehand and discuss options with the clinician.
