Copper coil failure

Dear Ask The Doctor: Wot makes the copper coil stop workin

Dear Sarah:

The most common cause of Copper coil failure is often caused by unnoticed expulsion (In a few clinics, the expulsion rate is as high as 10 per cent.) or when it is not placed properly.

This is why it’s a good idea to check your vagina regularly with your fingertips, to make sure that your IUD is not ‘coming down'. All you should be able to feel are the threads not the device itself, which would feel hard to the touch.

On the other hand, no contraceptive method is 100% effective and certainly pregnancy can happen with oral contraceptives, copper coils as well as other methods.
