A 5AA blastocyst is probably one of the best embryos that we can get, but, unfortunately, having a good morphology does not necessarily mean that the embryo is of good quality.  It only means that the chances of having normal genetics and implantation are going to be higher.

When we grade an embryo 5AA, it means that it has almost done the hatching, and both the inner cell mass and trophectoderm are of top quality.  The chances for one of these embryos, though it will depend on the age if we get this quality in egg donation, the pregnancy rate should be around 60-65% with just a single embryo transfer.

About this question:

What does it mean the embryo is graded 5aa? What is the chance this embryo will implant?

Embryo graded 5 AA would be of the highest quality, such embryo is a hatching embryo. Can a 5AA embryo be abnormal? What does 5AA embryo mean?
