Grade 1 hatching blastocyst
WebGrading Blastocysts Expansion Blastocysts sizes are measured on a scale of 1 to 6. Early blastocysts, with fewer cells, are graded as 1 or 2. Because these have fewer cells and a poorly defined inner cell mass and trophectoderm (see below), they are not given any letter grades like the more advanced blastocysts are. WebBLASTOCYST GRADING SYSTEM Initially, blastocysts are given a numerical score from 1 to 6 based upon their degree of expansion and hatching status: Grade Characteristics Grade 1: Early blastocyst: the blastocoel being less than half the volume of the embryo. Grade 2: Blastocyst: the blastocoel being more than half the volume of the embryo.
