@allykat111 whoops I pressed send before finishing. I am sorry to hear your relationship was strained following the procedure. We too had a difficult time after the TESA. My DH also offered to leave and I think I had a night with my mum when we had a big argument but it's understandable under the strain of the relationship what we were going through.
We were told no sperms on every occasion so you have something few of us have had which should be cause for hope! He will come around.
My only suggestion would be to think about preparing for a backup plan if you go through with egg retrieval as it would be very sad to get to mTESE and egg retrieval and not have anyway to fertilise the eggs if DP sperm is not good quality. Unless you are prepared to lose your eggs or have them frozen until you decide what to do (which I know of a couple of women who have done that but just beware the eggs may not survive the thawing).
