RÉSUMÉ
Despite advances in the field of male reproductive health, idiopathic male infertility, in which a man has altered semen characteristics without an identifiable cause and there is no female factor infertility, remains a challenging condition to diagnose and manage. Increasing evidence suggests that oxidative stress (OS) plays an independent role in the etiology of male infertility, with 30% to 80% of infertile men having elevated seminal reactive oxygen species levels. OS can negatively affect fertility via a number of pathways, including interference with capacitation and possible damage to sperm membrane and DNA, which may impair the sperm's potential to fertilize an egg and develop into a healthy embryo. Adequate evaluation of male reproductive potential should therefore include an assessment of sperm OS. We propose the term Male Oxidative Stress Infertility, or MOSI, as a novel descriptor for infertile men with abnormal semen characteristics and OS, including many patients who were previously classified as having idiopathic male infertility. Oxidation-reduction potential (ORP) can be a useful clinical biomarker for the classification of MOSI, as it takes into account the levels of both oxidants and reductants (antioxidants). Current treatment protocols for OS, including the use of antioxidants, are not evidence-based and have the potential for complications and increased healthcare-related expenditures. Utilizing an easy, reproducible, and cost-effective test to measure ORP may provide a more targeted, reliable approach for administering antioxidant therapy while minimizing the risk of antioxidant overdose. With the increasing awareness and understanding of MOSI as a distinct male infertility diagnosis, future research endeavors can facilitate the development of evidence-based treatments that target its underlying cause.

<p><b>AIM</b>To test the hypothesis that levels of sperm disomy fell significantly in six men treated by traditional Chinese medicine (TCM).</p><p><b>METHODS</b>Fluorescence in situ hybridization (FISH) was done on the sperm heads of six men before and during treatment by TCM.</p><p><b>RESULTS</b>There was a significant reduction in sperm disomy in all six men. This coincided with TCM treatment.</p><p><b>CONCLUSION</b>This is the first study reporting a significant reduction in sperm disomy in men over a given time course. The fact that this coincided with TCM treatment is intriguing but no conclusions can be drawn from this until placebo-controlled clinical trials are implemented.</p>
