tPNF, timing of the fading of both pronuclei; t2, timing of division to two completely separated blastomeres, for the patients, the t2 indicated the timing of the finish of the first division; ECC1, the duration of the first division; DC, direct cleavage; DA, developmental arrest; FC, failed cytokinesis; RC, reverse cleavage; UB, uneven blastomeres; BF, big fragment; FR, scattered fragments after division
