One of my very good friends got this...like you say, as a result of an aggresive D and C. I was also her doula and they "manually removed" her placenta, leaving behind bits, which is why the D and C came about.
They completely steralised her, its taken 5 years to go to court (UK), they lost her notes, Dr's got moved on etc, total nightmare for her. Made much harder by the fact that she also now lives in Australia.
Of course she lost her case, but its over now, she has a beautiful child and has since met and moved in with a guy with a big family.
She hasnt completely given up, she has had surgery a couple of times and she tries every alternative remedy,
She was very involved with the asherman support group in the UK and I'm sure has found some kind of support here too, I can find out details if you like, she knows a few women now with similar conditions and some do have wonderful success stories!!
