Intrauterine system – IUS (hormonal coil)

We can discuss the IUS as a contraception option, and provide insertion/removal as required. You will first need to book a telephone appointment to discuss your needs. If you opt for this method of contraception, you will be added to a waiting list and we will contact you once it is your turn to book.

What is it?

The intrauterine system (IUS) is a small, T-shaped plastic device that is inserted into the womb and contains a slow release hormone.

An IUS is also known as a “coil”.

How it works

An IUS thickens the cervical mucus to prevent the sperm from meeting an egg. It also thins the lining of the womb to stop eggs implanting.

An IUS is inserted by a trained doctors or nurse. It can stay in place for up to five years, although it can be removed earlier.

It is over 99% effective and is instantly reversible once removed, which means that most women will be fertile again and potentially able to become pregnant immediately after the IUS has been removed.

The IUS is often recommended for women who have heavy periods as it may improve their bleeding pattern.

About the procedure

You will lay on a bed and a speculum will be inserted in to the vagina. Using special tools, the clinician will insert the IUS through your cervix in to your womb. IUDs have a string at the bottom that hangs down into your cervix and vagina. They will trim this string so only about an inch or two hangs into your vagina.

During the procedure a chaperone will need to be present. This will be another member of the clinical team who joins the consultation to oversee the procedure.

You will be given any relevant information and aftercare advice.
