Even worse, I bet delivery would have to be c section....but how about carrying? I bet damage is done to the cervix from the 'reconstruction' (what ever that is!).
I would think that any surgery mucking about with the plumbing, as it were, would make it harder to carry a baby to term, as well as to deliver. Obviously, sometimes surgery is necessary to correct a real problem, and you weigh what's fixed against greater difficulties in childbearing (if you're planning on that :-).
Potential infection seems like a real problem with this type of surgery.
