Abstract
The literature review of sperm DNA fragmentation is evaluated. Russian and foreign literary data over the past 10 years, including fundamental researching of the evaluation of the gametes genome integrity, are analyzed. The main etiological factors and the possible reasons of the DNA breaks formation on the different stages of spermatogenesis are described.

The relationship between DNA fragmentation of spermatozoa pregnancy and live birth rates in the assisted reproductive techniqueare noted.
