The copper coil

The copper coil is a small T shaped plastic frame with copper wire. This is put into the woman’s womb.

It is:

  • 99% effective 

How does it work?

It can work in one or all of three ways:

  • by stopping the sperm from reaching and combining with the egg
  • by delaying the egg getting to the womb
  • by preventing an egg from settling in the womb

Copper is toxic to both the sperm and the egg.

The copper coil can be used as an emergency contraceptive method.

If you are considering having a coil fitted, talk to a doctor who will assess what contraceptive option is best for you.


  • The coil does not interrupt sex.
  • It works as soon as it is inserted.
  • It can stay in for up to 5-10 years.
  • If inserted after the age of 40, it may stay in place until the menopause.


  • It may cause some women to have heavier, longer periods.
  • It can only be Inserted and removed by a specially trained doctor.
  • The IUD does not protect against sexually transmitted infections (STIs). By using condoms as well as the IUD, you'll help to protect yourself against STIs.
