( b ) Early hatching blastocyst 121 h post insemination (day 5, p.m.). ( c ) Late hatching blastocyst 138 h post insemination (day 6, a.m.). ( d ) Hatching almost completed 144 h post insemination (day 6, p.m.). ( e ) Two completely hatched blastocysts with empty zonae 145 h post insemination (day 6, pm). ( f ) Healthy hatched blastocyst with distinct inner cell mass (ICM), trophoectoderm (TE) and expanded blastocoel 147 h post insemination (day 6, p.m.).
