Cryoprotectant effect of different antioxidants added to bovine sperm

An abstract of a study by Valdez-Torres et al evaluating the cryoprotectant potential effects of cysteine, caffeine, ascorbic acid, and Rhus trilobata plant extract (RT) added to extender for cryopreservation of bull semen on post-thawed semen traits is presented. Results indicate that the addition of RT to the extender for cryopreservation of bull semen allows better preservation of both the cellular characteristics and the motility parameters of post-thawed bovine sperm.
