Yeah, they say that the freezing/thawing can harden the zona pellucida, so they do it after thaw, before transfer. It's amazing the things they can do! I think ICSI is the most amazing. We haven't had any fertilization issues so far, so we haven't used ICSI, but I think it is just a stunning thing.
