100-BV-1 Hatching blastocyst with flat inner cell mass at 2 o’clock and some loose fragments around ICM 100-BV-2 Fully expanded blastocyst with large, compact but flat inner cell mass at…

98-BV-1 Blastocyst 2bb with defined inner cell mass and long, ellipsoid cells in trophectoderm 98-BV-2 Early blastocyst slightly contracted with degenerated excluded fragments between 9 and 12 o’clock position and…

97-BV-1a Coherent trophectoderm 97-BV-1b Inner cell mass compact and well defined, some dark granulation on the surface

96-BV-1 Expanded blastocyst with high inner cell mass, peak cell with a vacuole

95-BV-1 Blastocyst 2cb before vitrification, no defined inner cell mass visible, instead large blastomeres in blastocoel with apparent granulation in trophectoderm 95-BV-2 Contracted blastocyst before vitrification, cells appear dark granular

94-BV-1 Blastocyst 4ab before vitrification with nice clumped inner cell mass, slightly granular trophectoderm cells 94-BV-2 Blastocyst 4bb with elongated, flat inner cell mass, ICM and trophectoderm cells with granulation

93-BV-1a Expanded blastocyst with cohesive but slightly granular trophectoderm cells

92-BV-1 Blastocyst with big, compact inner cell mass, several cytoplasmic strings between ICM and trophectoderm

91-BV-1 Before vitrification, notable a relatively thick ZP 91-AW-1 No contraction after warming, cells appear clear and viable

90-BV-1 Blastocyst 4bb before vitrification, one necrotic cell at 2 o’clock, granular trophectoderm cells 90-BV-2 Before vitrification blastocyst 2bb with large cells visible in inner cell mass
