Sperm DNA integrity is vital for successful fertilization, embryo development, pregnancy, and transmission of genetic material to the offspring. DNA fragmentation is the most frequent DNA anomaly present in the male gamete that has been associated to poor semen quality, low fertilization rates, impaired embryo quality, and preimplantation development and reduced clinical outcomes in assisted reproduction procedures. This work summarizes the causes of fragmentation in the spermatic DNA, and its relation with seminal parameters, male aging, and results in assisted reproduction procedures.

The integrity of genetic material in the sperm is crucial for successful fertilisation and normal embryo development. Sperm DNA fragmentation is a term used to denote abnormal genetic material within the sperm, which in turn may lead to male subfertility, IVF failure and miscarriage. A conventional semen analysis done for sperm concentration, motility analysis and morphology assessment cannot assess the sperm at the molecular level and as result aid the detection of DNA fragmentation. In men, the major contributing factor for sperm DNA fragmentation is oxidative stress, which can be associated with one or more of the following:.
