title: Sperm DNA fragmentation and base oxidation.
abstract: Sperm DNA damage has been shown to be a valuable diagnostic and prognostic biomarker for male infertility and assisted reproductive treatment (ART) outcome. It is linked to every fertility checkpoint from reduced fertilization rates, lower embryo quality and pregnancy rates to higher rates of spontaneous miscarriage and childhood diseases. It is more robust than conventional semen parameters.The aim of this chapter is to provide an overview of current laboratory tests and relationships between sperm DNA damage and clinical outcomes. The conclusion is that sperm DNA damage is an important indicator of semen quality, and its routine use in the fertility clinic would improve ART success rates.
