AN IONIC CHOICE
The intrauterine device (IUD) is a small, T-shaped device that contains a copper thread. Also known as the copper coil, instead of hormones it releases copper ions that immobilize sperm and stop them from fertilizing the egg. Should a sperm manage to get through, the copper also prevents a fertilized egg from implanting in the womb lining, so you're still protected against pregnancy.
As no contraception method is for everyone, it's important to discuss the copper coil with your doctor or nurse first. Once you've decided an IUD is the right contraception method for you however, there's not much more for you to do. Your doctor or nurse will insert it for you, and it will remain effective for up to 5 to 10 years. Once removed, fertility quickly returns to normal.
