I believe a reversal at this stage would most likely not work - i am to believe that after several years its basically not worth even going down the reversal path - but hey who knows. If the specialist thinks there is more chance with ivf i would probably go that path - maybe they should get another opinion before they make up their minds. And i do believe they would most likely need icsi - but i am not an expert. Wishing your friends the best of luck.
