Hey Vicki

I'm not sure but I think it is quite common for embies to lose cells. But it does seem that the accepted level varies from clinic to clinic. SIVF have a min. of 70%. (They seem to be quite strict on all fronts).

I spoke with the Scientist when I had my transfer on 2nd May and he said that when an embie loses cells that you don't end up with eg. 70% of a baby (if successfull), the embie just pushes those cells out (when hatching) and continues to grow.

Also from what he said the embie shrinks to a very small size when frozen inside the zona and whats important is that it needs to expand when thawed. This part is critical. Did they explain this part to you?

Lots and lotsfor you.
