^{a, b)}Numbers with different lowercase superscript letters in the same column differ significantly. Total blastocyst includes early, expanded, and hatched blastocysts. The percentage of blastocysts at Days 6 to 8 were expressed based on the number of oocytes at the onset of culture, and the percentages of expanded and hatched blastocysts at Days 7 and 8 were expressed based on the total number of blastocysts at the same day.
