The Copper Coil (IUD)

• Over 99% effective
• lasts 5 to 10 years (depending on type)
• Upon removal, immediate return to fertility
• The copper creates an unwelcome environment for sperm and eggs in the womb, preventing fertilisation

Benefits:

• No hormone so no hormonal side-effects & you can still breastfeed
• Lasts a long time & works straight away
• No interruption of sex
• Not interfered-with by any medicines – always works
• If you are 40y.o or older when it is fitted, it can be left in until the menopause

Drawbacks:

• Periods will continue and can be heavier or more uncomfortable for 3-6 months
• Small risk of infection following coil insertion
• Small risk of the contraceptive coil moving or being pushed out of place – we will teach you how to ensure it is in the correct position
• Doesn’t protect against STDs

The Intrauterine System (IUS) e.g. Mirena

• Over 99% effective
• lasts 3 to 5 years (depending on brand)
• Releases hormone progestogen into the womb
• Upon removal, rapid return to fertility
• Thickens cervical mucus, making it difficult for sperm to get through the cervix, thins the lining of the womb so an egg finds it difficult to implant and can in some patients stop release of an egg (ovulation)

Benefits:

• It can make your periods lighter, shorter or stop altogether – can help those with heavy or painful periods
• It can be used by those who can’t use combined contraception eg migraines, overweight
• No interruption of sex & you can breastfeed
• Not interfered-with by any medicines – always works
• If you are 45y.o or older when it is fitted, it can be left in until the menopause

Drawbacks:

• Periods  may become irregular or stop completely, which may not be suitable for some people
• Some experience headaches, acne or breast tenderness after insertion – but usually settle with time
• Some women can have mood changes
• Uncommonly some people can develop small cysts on the ovaries, usually disappear without treatment
• Small risk of infection after insertion and small risk of it being pushed out by your body (we will teach you how to check its in place regularly)
• Doesn’t protect against STDs
