a Comparison of sperm DNA fragmentation before and after treatment with NAC (N = 50). Percentage of DNA fragmentation in sperm significantly decreased after treatment with NAC compared to before treatment. b Light microscope observation of sperm morphology c DNA fragmentation was assessed by TUNEL assay. Red-staining sperm have intact DNA, while green-staining sperm have DNA fragmentation. Statistical analysis was performed by the paired t-test. NAC; N-acetyl-L-cysteine. * P < 0.05
