Figure 4.

Difference in mtDNA/gDNA ratio in the culture medium of embryos with different fragment content at day 3. The mtDNA/gDNA ratio corresponding to different proportions of embryo fragments in the embryo culture medium were divided into three groups: Fragmentation of embryos in the first group is less than 10% (n = 127), the fragment content of embryos in the second group is between 10% and 15% (n = 59), and in the third group, embryo fragmentation>15% (n = 37). One black dot, black triangle, or black square represents one sample. Data are presented as the median with interquartile ranges (Q1–Q3).
