  1. 1 GFP-positive blastocyst rate (described as the total number of GFP-positive blastocyst/total number of blastocyst)
  2. ND: not determined as the fertilization did not occur or no plasmid constructs were present in the sperm incubation medium
  3. Data are shown as mean ± SEM of five replicates (n = 5). Fertilization rate was assessed using a one-way ANOVA followed by the Games-Howell Post Hoc test. The rates of a four-cell embryo, compacted embryo, and blastocyst were analyzed using the Kruskal-Wallis test. The rate of GFP-positive blastocyst was assessed using a one-way ANOVA followed by Tukey’s Post Hoc test
  4. a,b significant differences (p < 0.05) exist between values in the same column when accompanied by different superscripts
