Abstract

Male infertility is solely responsible for 20?30% of infertility cases. Oxidative damage of sperm DNA is positively linked with oligoasthenoteratozoospermia (OAT), and male infertility. The antioxidants are being explored worldwide to combat OAT, sperm DNA fragmentation and reactive oxygen species. The objective of the study was to assess the effectiveness of an antioxidant blend in improving sperm count, semen parameters and reducing DNA fragmentation index (DFI) in sub-fertile males. A prospective, double-blind, randomized, placebo-controlled trial was conducted in 300 sub-fertile males (25?45 years) from ten study sites in India. Subjects were randomized in either the antioxidant blend treatment group or placebo group. We assessed changes in sperm count, motility, normal morphology, semen volume, and percent DFI before and after treatment (90 days). To further stratify data on different criteria post hoc analysis was performed. Statistical analysis was performed using SPSS 10.0 software. There were improvements in sperm count, semen volume, sperm motility, and sperm normal morphology in the treatment group. There was improvement in sperm count in severe oligospermia subjects (sperm count < 5 million/mL, 5?10 million/mL, 10.1?15 million/mL), and high-extremely higher baseline DFI (20?30%, 31?40% and above 40%), as per post hoc analysis. There was no premature discontinuation and adverse events were reported during the study, indicating safety and well-tolerability of treatment. Study results confirmed the well-researched fact of antioxidants being effective to reduce oxidative stress and thus improve sperm DNA integrity and also improved semen parameters in males aged 40 and above.
