Here's a little background.  DH is azoo.  They did an aspiration to see if they would be able to get sperm back in April and they found some.  Not a lot, but enough to do ICSI.  RE recommends that we should use DS as a backup in case on the day of they don't get the same results.  DH is still not 100% sold on the idea of using DS.  RE says he will aim to get 12-14 eggs.  He would like to use DH's sperm for all but 4 and then use DS for the last 4.  He says that there is still a chance that DH's sperm won't fertilize well. 

So, wwyd?  Fertilize all egss with DH's sperm and hope for the best or do all but 4 with DH's sperm and use DS? 

Thanks ladies!
