Blastocyst stage and descriptions [16].

Blastocyst stage	Stage	Description
Early blastocyst	1	Blastocoel that is less than half of the volume of the embryo
Blastocyst	2	Blastocoel that is half of or greater than half of the volume of the embryo
Full blastocyst	3	Blastocoel completely filling the embryo
Expanded blastocyst	4	Blastocoel volume larger than that of the early embryo, with a thinning zona pellucida
Hatching blastocyst	5	Trophectoderm starting to herniate though the zona pellucida
Hatched blastocyst	6	Blastocyst has completely escaped from the zona pellucida
