Oxidative origin of sperm DNA fragmentation in the adult varicocele [PDF]

International Brazilian Journal of Urology, 2021
Purpose: Sperm DNA fragmentation is a major cellular mechanism underlying varicocele-related male infertility. However, the type of DNA fragmentation - whether oxidative or of another nature - remains unknown.

Associations of sperm DNA fragmentation with lifestyle factors and semen parameters of Saudi men and its impact on ICSI outcome

Reproductive Biology and Endocrinology, 2018
Background Male factor infertility is quite common as 30–50% of infertility cases are due to sperm defects. The high sperm DNA fragmentation is one of the causes of male factor infertility.
