An intrauterine device (IUD) or intrauterine system (IUS) are two different types of contraceptive coils (sometimes known simply as a coil). They are both very effective at preventing pregnancy.
A contraceptive coil is a small device that is inserted into the womb. An IUD will work for 5 to 10 years, and an IUS works for 3 to 5 years, so you don’t need to remember to do anything else to prevent pregnancy during this time.
A coil does not protect against HIV or other sexually transmitted infections (STIs). So even if you decide to use one you should use condoms as well.
What is a contraceptive coil?
A small, Tshaped device. It has two thin threads that hang down from your womb into the top of your vagina.
Although an IUD and an IUS look similar, they are made out of different things. The IUDis made out of plastic and copper (which is why some people call it a copper coil or a copper IUD).An IUS does not have copper in it. It contains the hormone progestogen instead.
Where can I get a contraceptive coil?
A trained healthcare professional will fit your coil, normally at a sexual health clinic or your local health clinic.
How do contraceptive coils work?
The IUD releases copper into the womb, while an IUS releases progestogen. Both these things change the mucus inside the cervix (the womb’s entrance), which makes it harder for sperm to reach an egg and survive. It also stops a fertilised egg from implanting itself in the womb and growing.
The coil is fitted by gently putting a smooth, tubeshaped tool (a speculum) into your vagina so that it can go into your womb. Fitting it should take around five minutes, and you are likely to be tested forSTIsbeforehand.
The healthcare professional who fits your coil will show you how to find the threads so you can check each month that it is still in place.
How often do I need to get a contraceptive coil?
Every 5 to 10 years for the IUD. Every three to five years for the IUS.
What do I do if forget to replace my coil?
You should go to your doctor. You might also consider takingemergency contraception.
You should also use condoms if you have sex, at least until you get a new coil or swap to a different contraceptive method.
Do I still need to use condoms if I’m using a contraceptive coil?
Condoms are the only type of contraceptive that protect you and your partner fromHIVandSTIs,so it is worth using them even if you have a contraceptive coil.
Will using a contraceptive coil harm my chances of getting pregnant later on?
No. Once a coil is removed, you’ll be able to get pregnant straight away.
