Can you explain the ratings that the embies are given at HRC? What's the "best" rating and so forth....Also does it make a difference in the pregnancy rate? Better rated emby = BFP in most cases?

Bump, I'd like to know the answer to this too, especially because I have 6 GSN girls, all different grades, on ice.
I had 6 embies make it through PGD. 5 were blasts and were graded B/C, the other was a morula and it did not get it a letter grade.
We use a system for day three embryos that is:Quote:

For blasts
The grading of blastocysts is complicated. It involved examining the inner cell mass and trophectoderm and grading them with a letter grade.
A=best
D=worst
I hope that this helps
Thanks Dr. Potter!
