Good quality expanded blastocyst (Grade 4:1:1) with a large mushroom-shaped ICM and a well organized TE. There appears to be cytoplasmic strings extending from the ICM to the TE. The blastocyst was transferred and implanted.
Figure 390
Hatching blastocyst (Grade 5:1:2) with a large stellate ICM that seems to be connected to the TE cells with short triangular cytoplasmic strings or bridges. The blastocyst was transferred but failed to implant.
Figure 391
Hatched blastocyst (Grade 6:1:1) that is now completely free of the ZP showing a compact ICM that appears to be connected or anchored to the TE by a broad triangular bridge. The blastocyst was transferred but the outcome is unknown.
