Non-hormonal copper Intrauterine Device (copper IUD)

The copper IUD can be fitted either in the first 48 hours after delivery or 4-6 weeks later. This will be discussed by your midwife or doctor before you give birth and can be planned for the time of your delivery. It can also be inserted at the time of a planned caesarean section.

The copper IUD is a t-shaped device that is placed in your uterus (womb) which releases copper. It can last either 5 or 10 years based on the device fitted. 

The copper alters cervical mucus, which makes it more difficult for sperm to reach an egg and survive. It can also stop a fertilised egg from being able to implant itself. 

It is more than 99% effective. That means fewer than 1 out of 100 people who use a copper iUD will get pregnant each year.

  • Suitable for breastfeeding women
  • Lasts at least 5 or 10 years; once in place you do not need to think about contraception.
