Percentages of human sperm exhibiting high and low mitochondrial membrane potential (ΔΨm)a, and evaluation of DNA fragmentationb, in human sperm samples after 6 h of in vitro incubation without bacteria (Vehicle), or with increasing concentrations of EBs of CT serovar E or serovar LGV. Data are shown as mean ± SD, n = 36. Statistical analysis was performed using one-way ANOVA with Bonferroni post hoc test analysis. *p < 0.05.
