Intrauterine device (IUD)
What is an IUD?
An IUD is a small T-shaped plastic and copper device that is inserted into your womb by a specially trained health professional.
There are various types and sizes available. Depending on the type; an IUD can last from 3 to 10 years. It used to be called a coil.
The IUD is a long-acting reversible contraceptive (LARC) method. This means that once it’s in place; you don’t have to think about contraception every day or each time you have sex.
You can use an IUD whether or not you’ve had children.
How it works
The IUD works by preventing sperm from surviving in the cervix; womb or fallopian tubes. It may also prevent a fertilised egg from implanting in the womb and thins the womb lining.
Intrauterine system (IUS)
What is an IUS?
An IUS is a small; T-shaped plastic device that contains progestogen. It is inserted into your womb by a specially trained health professional.
The IUS is a long-acting reversible contraceptive (LARC) method. Once it is in place; it works for 5 years; so you do not have to think about contraception every day or each time you have sex.
The brand name of the IUS used in the UK is Mirena.
You can use an IUS whether or not you have had children.
How it works
The IUS releases a progestogen hormone into the womb; which thins the womb lining so that it’s less likely to accept a fertilised egg; thickens the mucus from your cervix; so it’s difficult for sperm to move through and reach an egg; and stops ovulation in some women.
