CoQ10 modestly improves fertility in men

Supplements of co-enzyme Q10 (CoQ10) may improve the motility and density of sperm in infertile men, according to a new study using Kaneka’s ingredient. Dr. Mohammad Reza Safarinejad from Shahid Beheshti University in Tehran, Iran, recruited 212 infertile men and randomly assigned them to receive 300mg of Kaneka’s CoQ10 daily or placebo for 26 weeks. This was followed by 30 weeks with no intervention. The Tehran-based researchers reported a significant improvement in both sperm density and motility following supplements of CoQ10. A positive association was also found with regards to sperm count. Further analysis showed an increase in the percent of normal forms of sperm, added Dr. Safarinejad.

Finally, an increase in the acrosome reaction of over 100 per cent was observed in the CoQ10 group, compared to a 1 per cent increase in the placebo group. The acrosome reaction aids in egg penetration, and subsequently fertilisation. The study is published currently in July 2009 issue of The Journal of Urology.
