Figure 3. Effects of ZG on serum testosterone concentration in CP-treated mice. CP administration significantly decreased testosterone levels (***p<0.001 vs control). Co-treatment with ZG at 20 and 40 mg/kg (CP +ZG20 and CP +ZG40 groups) significantly restored testosterone levels compared to CP group (##p<0.01), while CP +ZG10 showed a modest increase. Data are presented as mean±SD (n=6). *p<0.05, **p<0.01, ***p<0.001 vs control group; ^#p<0.05, ^##p<0.01 vs CP group (one-way ANOVA followed by Tukey’s post-hoc test).
