I have recently been speaking to my doctor about this very thing.
The advice given to me is wait until you've had your family before the reconnective surgery- for me, this was explained that this is becasue any major pelvic operation runs the risk of causing adhesions which may affect fertility, and also because the body requires recuperation time of about a year following the operation.
In addition, if you're in remission prior to having a baby, you can flare up afterwards, in which case a bag might be a better idea than having to leg it to the loo.
With the configuration of my bowels post-surgery, it would be possible for me to have a natural birth, although I have expressed a preference for an elective caesarian. This was fine, she said, but the colorectal surgeon would have to confer with the obstetrician over the c-section's method.
