摘要: Abstract This study examined the effect of cryoprotectants on DNA integrity, antioxidant defense, and resistance to oxidative stress in cryopreserved sterlet Acipenser ruthenus sperm. The freeze-thaw process significantly influenced sperm motility, with significant differences among cryoprotectants. In vitro exposure xanthine–xanthine oxidase (X–XO) system as a model reactive oxygen species inducer resulted lesser motility rate velocity compared control, there was decrease these variables time- dose-dependent manner. greatest X (0.6 mM)–XO (0.05 U/mL) concentration incubation period (30 min) associated 62% fragmentation 10% ethylene glycol (EG). maximum lipid peroxidation (LPO) carbonyl derivatives proteins (CP) also observed EG exposed X–XO at 0.6 mM X–0.05 U/mL XO. frozen/thawed containing that dimethyl sulfoxide (DMSO) had enhancement superoxide dismutase (SOD) glutathione reductase (GR) activity. current confirms is not effective for cryopreservation, were highly sensitive free radicals after cryopreservation EG.
