I didn't even know they came in copper!
Copper, like the element copper? Some people have a rare disease such that their bodies can't absorb copper in their blood stream and so it builds up in their brain and it can kill them.
I would get checked out for this disease before trying it at least. Assuming it's the element copper.
It's called Wilson's disease and it's very serious. You should be tested for both it and atopy (allergy susceptibility) before getting one. I would hope your OBGYN has already informed you about all this.
I had an IUD (or coil as we call them here) for many years and it worked fine, although I had heavier periods.
Only complaint was that the nylon threads annoyed my ex husband immensely as they stuck into the tip of his penis during sex (shocked me, didn't think it would reach that far up! haha)
ML - yes, but I lack the money for such a procedure @ the moment, and most places won't perform the surgery if you're under 40 besides.
