ICSI failed for us a few weeks ago. I didn't have any bleed during the 2ww just some cramping. When we attended our review meeting as to why it didn't happen they said there was a 'darkened zona' and the outside of the egg was tough when they injected it for ICSI. Even though we had a perfect 4 cell transfer on day 2, I wonder if that means the embryo couldn't hatch? Has anyone else experienced this or heard of anything similar? I was looking at a private website and it mentioned 'Assisted Hatching' but our clinic has said that would not work for ICSI as the embryo is already weakened by the needle anyhow. I have been advised to go for egg donors or give up, and I'm not ready to do that just yet. We've been through so much over the years. Does anyone have any ideas why our little one didn't hatch or what we could do next time? So confused and upset.
