Dear members

A friend of mine who is CS devotee asked me a very good question. She has a 
grown-up daughter who is a bit of a hypocondriac, so she is really trying hard 
to get her onto CS. However, the daughter has a conctraceptive loop fitted.

As a medical pathologist, my friend is pretty knowledgable about diseases and 
various medical treatments. She maintains that the contraceptive loop works by 
creating a low grade infection - so if a fertilized egg comes into contact with 
the loop, it is infected and rendered useless. She says that no medical doctor 
will tell you this, but this is apparently how a loop works.

The question is this: Will CS clean out the infection (I am certain it would) 
and thus render the loop useless in its contraceptive function? .

She says she'd rather have her daughter sick than pregnant! (at this stage).

BTW, I've heard that they used to make these loops out of copper - which would 
also be anti-bacterial. (This tends to confuse the issue even more)

Can any of you informed members shed some light on this dilemma? 

Any and all replies will be appreciated.
