Also know as the coil, IUD is a small plastic and copper T shaped device that is fitted in the womb. It can be fitted up to 5 days after unprotected sex.
How an IUD works
The main way an IUD works is to stop sperm reaching an egg. It does this by preventing sperm from surviving in the cervix, womb or fallopian tubes. It may also work by stopping a fertilised egg from implanting in the womb.
IUD does NOT cause an abortion.
Where to get an IUD
The Emergency IUD can only be fitted by a trained doctor or nurse and therefore is usually only available from:
- CASH (Contraceptive & Sexual Health Clinic)
- Some GPs that provide Contraceptive Services
- Some Young People's Clinics
- Some GUM Clinics
Unlike the IUD, the IUS is plastic only. It is is a small plastic device which is inserted into the uterus and slowly releases a hormone called progestogen which is similar to the natural progesterone produced in the ovaries of a female.
The difference between an IUD and an IUS
IUS is a small plastic device that contains a hormone. The IUD is a small plastic and copper device that doesn't contain any hormone.
Long acting reversible contraception (LARCs)
There are many long acting reversible contraception methods that can be used as a form of contraception (e.g. implant, injection and the IUD/IUS). The main differences between these methods and other methods of contraception are that they are long-lasting, easily reversed and you don't have to remember to take it every day.
All LARC methods are suitable for women of all ages. Other types of LARCs include:
