Great descriptions / explanation of the Gard.ner embryo grading system. Also includes pictures. Wow!
Was just googling different IF related topics and found this great resource. Thought I would share in case it helps someone else out.
Different clinics use different grading methods, but I think this is one of the more standard scales.
I *think* this was developed at C.C.RM and is their current grading system... I don't know this for fact, though... so if someone can verify, that would be nice.
