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

89-BV-1a Few elypsoid trophectoderm cells 89-BV-1b Large compact inner cell mass 89-AW-1a After warming contraction of the blastocysts whereas the majority of the trophectoderm cells stay attached to the ZP…

88-BV-1 Compact inner cell mass before vitrification 88-AW-1 Half collapsed blastocyst after warming

87-BV-1a Before vitrification well-defined cohesive trophectoderm cells 87-BV-1b Inner cell mass compact but consisting of few cells 87-AW-1a No sign of contraction after warming
