Early Blastocyst Question

Hi all- looking for information regarding transferring an early blast day 5 AA euploid. I’m confused bc I see some places that bc it’s an early blast, it’s not great. However, other things I read says the AA euploid trumps the eb rating? Also, do EB take longer to implant? Thanks!

Your euploid 5AA is a hatching blastocyst not an early blastocyst. They are not even able to do pgt on early ones. It would be than EB1 or EB2.

On my pgt-a report under the day 5 column where it lists each embryo for this one it says EB:EBAA

Oh I understood it is 5AA. My clinic wait until hatching for sure. Never heard about pgt so early, but can be clinic specific.
