I would also question a sperm issue, though it sounds like your husband wouldn’t be very interested in considering donor sperm. Your fertilization rates are not great (bad eggs), but you are also not getting good blasts (bad sperm…especially if the numbers decline between days 3-5). We did a DE cycle and fertilized half of the eggs with DH’s sperm and half with donor sperm. It was a blessing that we did, because DH’s embryos did terribly! Our DE/DS blasts did wonderfully and we are now parents of twins. One of our babies could be DH’s (transferred 2 DE/DS and 1 DE/DH blast), but we’ll never know! Best wishes! As parents of double donor babies (most-likely), I can tell you with confidence that you WILL be their parents and you will be 100% in love!
As for coming on board…it was simple. Once I was forced to use donor eggs, my husband understood that there was a chance that he was part of the problem too. I’m sure he hoped we would never need the donor sperm blasts, but when our fresh DE transfer failed and I ended up seeing a therapist for depression…he really understood the emotional toll the process had taken. And…the writing was on the wall! I basically refused to go through anything else without using donor sperm and if the yearning to have babies had persisted with his refusal…I would have likely ended my marriage. I realize that’s extreme, but just being honest.
