Results of Spearman correlation analysis between Pb2 extrusion time and embryonic development and time parameters. tPNa time to pronuclear appearance, tPNf time to pronuclear fading, t2 time to the two cells, t4 time to the four cells, t8 time to the eight cell, tB time to full blastocyst formation, tHN time to the end of the expansion phase and initiation of the hatching process of the blastocyst, CC1 = t2-tPb2; S2 = t4-t3; S3 = t8-t5. A P value < 0.05 indicates that the difference is statistically significant.
