Thanks BW I thought the dye studies helped clean the tubes abit but I did hear once they have stuck together (or had junk in them) they are likely to go back the same way shortly after the dye studies anyway. Obviously we would like not to need assistance but after 12months of losses and knowing why now we don't want to waste another year in the hope we get UTD and its in the uterus. My fear is being in the same position in 12-18months time which emotionally I don't think I could handle. In saying this I also know IVF is no guarantee of a baby but it does give us hope. Thanks so much for your replies.
