Summary
Over the last decade it has become increasingly clear that semen analysis is insufficient to diagnose male infertility. With 30% of infertile men diagnosed as idiopathic, the ethics of continuing to rely on outdated diagnostic parameters must be questioned. Sperm DNA damage is a strong biomarker of male infertility. It also correlates significantly with increased risk of miscarriage after both natural and ART conception. Thirdly, sperm DNA damage is a useful predictive tool for both IVF and ICSI live birth success. DNA fragmentation can occur as double or single strand breaks. Oxidative stress is a common cause of single strand breaks and can be prevented by endogenous and dietary supplemented antioxidants. In contrast, double strand breaks are caused by dysfunction during spermatogenesis, and are harder for oocytes to repair post fertilization. Greater awareness of the relevance of DNA damage and its origins could aid fertility choices and outcomes.
