Contraception: The Coil

The Coil
Average rating: 3 out of 5 star rating

It's very small - not much longer than a matchstick, and is T-shaped. It's normally made of plastic and copper. Your womb (uterus) is actually only about the size of your clenched fist so if you put a matchstick in your palm that will show you how it fits.

Also known as: Intrauterine device, IUD
Where can I get it?
Some trained GPs and nurses can insert it, but it's most commonly available through your family planning clinic. Gynaecologists can fit them too. IUDs fold up and are then pushed through your vagina and expand into your womb. All coils have either one or two little threads, which hang down into your vagina. The doctor or nurse will use these to check that it's in place. They will also use them to remove it.
How does it work?
The coil stops your partner's sperm from getting into your womb. It changes the thickness of your cervix and makes it difficult for an egg to settle in the womb lining. It can also last from between 5-8 years depending on the make.
How effective is it?
It's 98% effective.
What are the good points about it?
Once it's in, that's it for 5-8 years. No worrying about booking repeat appointments or taking pills. Your normal level of fertility returns quickly after it's removed. Although some women find it painful when it's inserted and taken out, this is quite rare.
What are the bad points about it?
They can make your periods heavier, longer and sometimes more painful. Your doctor or clinic will need to order the coil in so you'll need to talk to them in advance if you want one. They don't protect you from sexually-transmitted infections. You will need to use condoms during sex for this.
