Schematic for oocytes randomized into either the time-lapse system (Group A) or the conventional incubator (Group B). GV = germinal vesicle; MI = metaphase I; MII = metaphase II; 2PN = two pronuclei; Excluded immature (GV and MI) oocytes and unfertilized oocytes in each group were circled in red. The total number of blastocysts associated with each group is circled in blue.
