The blastocyst is a hollow cellular mass generated during early development and composed of cells forming the trophectoderm, the inner cell mass, and the fluid- ...

Blastocysts were given a numerical score from 1 to 6 on the basis of their degree of expansion and hatching status, as follows: an early blastocyst with a ...
