How Do They Work?

IUD

The IUD coil or ‘copper coil’ is a little bit of plastic shaped like a T, that sits in the uterus. It is made from copper which is toxic to the sperm and also stops the egg from implanting into the womb.

It can stay in your body for 5-10 years or until you would like it taken out.

It can also be fitted as emergency contraception as it works instantly.

IUS

The IUS could or ‘hormonal coil’ is is a little bit of plastic shaped like a T, that sits in the uterus. It is contains the hormone progestogen, which thickens the mucus around the cervix, making it harder for the sperm to get through. On top of this, it makes the lining of the womb thinner so that a fertilised egg cannot implant.

Some people stop ovulating (ovaries release an egg) and bleeding on this coil, however most continue to ovulate.

What To Expect At Your Appointment

Both the IUD and IUS need to be fitted by a trained nurse or doctor.

During the appointment you can expect the nurse to ask you a few questions and to check your vagina is suitable for insertion and that you don’t have an infection down there – if so you will be given some antibiotics.

The actual fitting of the IUS/IUD should take no longer than 5 minutes. You can sometimes be given some painkillers or local anaesthetic to help with the pain, although some people find it just a little uncomfortable.

You will be asked to lay on the bed with your bottom half of your clothing removed. You will then open your legs and bend your knees and they will insert a speculum inside your the vagina and insert the coil.

The IUS is often used to help with endometriosis pain and the IUD can be used as an emergency contraception as it works instantly.

Once the coil is fitted you will feel some period contraction like pain as your body is trying to remove the ‘foreign object’ along with some light bleeding. However, this should subside within a few days.

You should go back to the or doctor or nurse if you have severe or prolonged stomach pains, especially if you feel unwell, hot and clammy or heavy vaginal bleeding with or without clot.

Removal is the same as insertion but in reverse but it should be less uncomfortable!
