Oxidative Stress and Gamete Cryopreservation

Cryopreservation enhances production of ROS that induce membrane LPO, DNA damage, and apoptosis in frozen spermatozoa1 [206] . Removing the seminal plasma leaves spermatozoa unprotected by antioxidants which will affect cryopre-served spermatozoa negatively. The addition of antioxidants to the thawing media improves spermatozoa function and in vitro fertilizing capabilities [215]. DNA damage was reported in cryopreserved oocytes due to oxidative stress [216]. Using the antioxidant vitamin C in the culture media reduces the stromal tissue apoptosis and damage [217].
