(I) Day-3 embryos (a) before vitrification and (b) immediately after warming. (II) (a) Day-3 embryos before vitrification; (b) day-5 blastocysts developed from the day-3 warmed embryos. (III) Day-5 blastocyst (a) before vitrification and (b) 1 hour after vitrification (the reexpansion has not been completed); (c) fully reexpanded 3 hours after warming. (IV) Hatched day-6 blastocyst (a) before vitrification and (b) 1 hour after vitrification (the reexpansion has not been completed); (c) fully reexpanded blastocyst 5 hours after warming.
