A host of tests designed to measure sperm DNA damage have been developed over the last few years. Medicinal antioxidant treatments have not been shown to be effective so far, but this is one area of research that is continuing. Sperm DNA damage measured by the alkaline comet assay as an independent predictor of male infertility and in vitro fertilization success.

Sperm DNA damage behind 80% of ‘unexplained infertility’ cases, says expert
Hum Reprod Update ;5: The authors wish to thank all the staff of Humanitas Fertility Center who contributed to this study, in particular Dr. A positive correlation between round cells concentration in semen major of 1. Accurate and understandable results may open up channels beyond antioxidant therapy, for example, employing advanced sperm selection technologies to minimise risk. These crystals are trapped within the cell but can be released by solubilization in a solvent solution; they produce and increase color intensity in the RG from yellow to different levels of purple-blue which can be easily and comparatively quantified by eye through the use of a color scale. Lianne Friesen and Nicholas Woolridge. A substantial body of evidence has accumulated in recent years that human semen quality may be deteriorating.
A positive correlation between round cells concentration in semen major of 1. A Systematic Review and Meta-Analysis. Detection of DNA strand breaks in individual apoptotic cells by the in situ terminal deoxynucleotidyl transferase and nick translation assay. This is because while most cell types are able to repair damaged DNA, sperm lose this ability during development and have to rely on repair mechanisms in the egg. Yet the role of sperm DNA damage in miscarriage is not surprising. Comparison of various levels of sperm DNA damage in outcomes of in vitro fertilization Click here to view. It is clear that more studies need to be conducted on the clinical utility of DNA fragmentation.
