Mirena Coil Fitting in Birmingham & Leicester

Home > Contraception and Sexual Health > Contraception Services and Family Planning > Mirena Coil Fitting (Intra-Uterine System)

An Intrauterine system (IUS) is a small t-shaped device which is inserted into the uterus by a trained doctor or nurse. The Mirena Coil is a progesterone-releasing IUS which has been shown to be 99% effective in preventing pregnancy. If you would like to discuss your IUS options, you could visit our clinics in Birmingham or Leicester and one of our GPs will be happy to provide all the advice you need.

How Does the IUS Work?


The IUD (Copper Coil) does not contain hormones, whereas the IUS does. The way it works makes it difficult for the sperm to get through by thickening the mucus around the cervix. The lining of the womb gets thinner so that the fertilised egg is unable to implant. 

Having the IUS Fitted in

One of our trained GPs will be able to insert the IUS in. The procedure usually takes around 10 minutes or less. Most often, the IUS will be inserted within seven days after the start of your period. Some women might experience slight discomfort and for this reason, a local anaesthetic can be performed to minimise this.

Follow Up

It is recommended to book in a follow up with one of our GPs 6 weeks after having the IUS fitting in. This way, it can be ensured that the threads of the intrauterine system are still visible and everything is ok.

Advantages of the IUS

  • The Mirena coil works for 5 years once inserted.
  • Periods will become lighter, less painful or may stop completely within the first year of use.
  • It is safe to use the Mirena coil if you are breastfeeding and it does not interact with other medicines.
  • A progesterone-releasing IUS is a good option for women who cannot tolerate oestrogen-based options.
  • It is possible to get pregnant as soon as the Mirena coil is removed.

Disadvantages of the IUS

  • Some women may experience side-effects such as headaches, breast tenderness, and acne after having the Mirena coil fitted.
  • Some women may experience changes in mood or libido with the Mirena coil, but this is usually very mild.
  • An IUS fitting can lead to infection which could spread to the pelvis if left untreated.
  • There is an increased risk of fluid-filled cysts forming on the ovaries as an uncommon side-effect of the Mirena coil.
  • The Mirena coil does not protect against sexually transmitted infection, so condoms may still be needed.
