The aim of this study was to investigate the effects of different concentrations of glutamine (experiment 1) and glutamine + cysteine (experiment 2) on post‐thaw sperm quality of South American silver catfish (Rhamdia quelen). The sperm was cryopreserved in cryoprotectant solution (fructose 50 g/L, powdered milk 50 g/L and methanol 100 ml/L) containing different glutamine concentrations (0, 2.5 and...
The cryopreservation promotes cellular damage that could compromise sperm quality in terms of motility and fertility rates, which may be caused by oxidative stress. Thus, the aim of this study was to assess the effects of cysteine addition on post‐thaw sperm quality, DNA damage and indices of oxidative stress of the South American silver catfish (Rhamdia quelen) sperm, compared with the cryoprotectant...
