Conclusion
The findings of this study strongly indicate that H2 treatment
activates low motility sperms. Importantly, recent
studies demonstrated that H2 might have potential for
wide use in medical applications as a novel, safe, effective
antioxidant with minimal side effects [14-19]. We
propose here that H2 is a new promising agent for male
infertility treatment. However, to make practical use of
H2 treatment, we further need to examine the effects of
H2-treated sperm on fertilizing ability, embryonic development
and safety for IVF and ICSI in future studies.
