Obesity induced the oxidative stress and poor sperm quality in mouse epididymis. A The body weight of obese mice significantly increased compared to that in control mice. B-C The comparisons between normal mice and obese mice in sperm motility and concentration. D In the caput epididymis of the obese mice, the ratio of the GSH/GSSG decreased. E The concentration of MDA increased significantly in the epididymis fluid of the obese mice. F The level of ROS increased in the sperm of obese mice. All data were presented as mean ± SD, *P < 0.05, **P < 0.01, ****P < 0.0001
