I don't know anyone whose had a tubal reversed, but I do know a woman who got pregnant with triplets after having had a tubal. The pregnancy went fine. The boys were all healthy and are now in high school.
My cousin's girlfriend had her tubes tied after her son was born. About 12 years later, she got pregnant with my nephew!! I think the pregnancy went ok. he is ok now. He is very smart and is your typical little monster boy!
