How does it work?
Primarily the IUD works by stopping the sperm reaching the egg by preventing sperm from surviving in the cervix, womb or fallopian tube.
You can go to a family planning clinic, sexual health clinic or a general practice. Some doctors and practice nurses will fit IUDs, but not all so do check.
Fitting an IUD takes about 15–20 minutes. It can be uncomfortable or painful for some women, and you might want to have a painkiller or a local anaesthetic. Your doctor or nurse should talk to you about this beforehand. You may get a period type pain and some light bleeding for a few days after the IUD is fitted. Painkillers can help with this.
Is it effective?
There are different types of IUDs – newer IUDs contain more copper and are the most effective. They are more than 99% effective.
Why should I get it?
It works as soon as it is put in
It works for three to ten years depending on type
It doesn't interrupt sex
It can be used if you are breastfeeding
Your normal fertility returns as soon as the IUD is taken out
It is not affected by other medicines
Why shouldn't I get it?
Your periods may be heavier, longer or more painful. This may improve after a few months
You will need an internal examination to check it is suitable, and when it is fitted
The IUD does not protect you from sexually transmitted infections, so you may have to use condoms as well. If you get an infection when an IUD is in place this could lead to a pelvic infection if it is not treated.
