IUD (copper coil)
The IUD (intrauterine device or ‘copper coil’) is a small ‘T’ shaped device that is inserted inside a woman’s womb. It can last between 5 and 10 years. The IUD is non-hormonal method of contraception and works because copper is toxic to sperm.
How effective is the IUD?
The IUD is more than 99% effective at preventing pregnancy (this means that each year less than one woman in a 100 will get pregnant using this method to prevent pregnancy).

Advantages
It works as soon as it’s inserted.
It won’t interrupt sex.
Your normal fertility returns as soon as the IUD is removed.
It can last anywhere between 5 to 10 years once inserted.
Disadvantages
In some women, their periods may become heavier and more painful.
A small number of women can get an infection in the first 20 days after insertion of the IUD.
The IUD can sometimes fall out but your Doctor/Nurse will show you how to check that it’s still in place.
Very occasionally (about 2 in 1000 women) the IUD may go through your womb.
How is the IUD fitted?
Your IUD is fitted by a Doctor or Nurse either at your GP or a sexual health clinic. Prior to fitting you will be given a full consultation to make sure the IUD is right for you. Fitting an IUD takes approximately 10-15 minute and involves being examined internally.
