I too had MANY chemicals with OE and my DE cycle wasn't stellar. I put DH on supplements for at least 3 months before doing DE to increase our odds in case it was him causing the problem. My DE cycle had 14 eggs, 9 embies (using ICSI)that were: cell - grade
4 3 (had no growth in 24 hrs)
(3) 2 4's
I transferred the top 3 and started with twins and ended with a singleton. I originally had plans to only transfer 2 but I had nothing to freeze so took a chance.
I will never know if it was him but the numbers weren't the best even with DE so I suspect it might have been. Put your DH on supps for at least 3 months before retreival.
Good luck, this sucks, I know. I hope the best for you.
