The sperm of Russian sturgeon (A. gueldenstaedtii) and Siberian sturgeon (A. baerii) was used to evaluate the effects of short-term (liquid) storage on functional parameters (spermatozoa motility and velocity), DNA integrity and oxidative stress indices. Spermatozoa showed >50% motility during 6 days of storage with an average velocity of 133.12±15.4 to(More)
The protective influence of seminal plasma and the antioxidants catalase (CAT), superoxide dismutase (SOD), and glutathione (GTH) on quality parameters, oxidative stress indices, and antioxidant activity was studied in common carp (Cyprinus carpio) spermatozoa exposed to the xanthine–xanthine oxidase (X–XO) system. Fish spermatozoa were incubated for 5 and(More)
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 of cryopreserved sperm to the xanthine-xanthine(More)
