Figure 6. Effects of ZG on the Bax/Bcl-2 ratio in testicular tissue of CP-treated mice. The Bax/Bcl-2 ratio was significantly elevated in CP-treated mice compared to controls (***p<0.001). ZG co-treatment at 20 and 40 mg/kg (CP +ZG20 and CP +ZG40 groups) significantly reduced the ratio compared to CP-treated mice (^##p<0.01), with CP +ZG40 showing the most pronounced effect. Notably, the ratio in CP +ZG20 and CP +ZG40 groups was significantly lower than in CP +ZG10 group (p<0.05). Data represent mean±SD (n=6 groups). *p<0.05, **p<0.01, ***p<0.001 vs. control; ^#p<0.05, ^##p<0.01, ^###p<0.001 vs. CP group (one-way ANOVA with Tukey’s post-hoc test).
