Sperm DNA Fragmentation Test. The genetic integrity of the sperm is crucial for successful fertilization and normal embryo development. Sperm DNA fragmentation is a term used to denote when the genetic material within the sperm is abnormal, which in turn may lead to male subfertility and IVF failure.s a second generation sperm DNA test. It detects the sperm with DNA damage and also tells how much DNA damage each sperm have. A SpermComet test result of 45% means that there is an average of 45% damage in each sperm that was assessed.
