Figure 4.

Comparison of morphokinetic parameters of the later stages of embryonic development between euploid and aneuploid embryos in the time-lapse monitoring group. t8 = time from insemination to 8 cells; tM = time from insemination to formation of a compact morula; tIB = time from insemination to initiation of blastulation; tFB = time from insemination to formation of a full blastocyst. tEB = time from insemination to formation of a expanded blastocyst. Morphokinetic data were presented as mean ± SD. There were no significant differences between euploid and aneuploid embryos in each of the morphokinetic parameters (p >0.05 by Mann–Whitney test).
