Abstract
Lipid peroxidation (LPO) of dog spermatozoa was assessed in fresh semen and in samples of the same ejaculates after freezing and thawing. Particular attention was paid to individual differences in the susceptibility to LPO and its possible relationship with freezeability. Innate levels of LPO were low in fresh spermatozoa but increased after thawing in one of the dogs included in our study. The level of lipid peroxidation in fresh spermatozoa was not correlated with that of thawed spermatozoa. Negative correlations were detected between the activity in seminal plasma of GPx and sperm velocities post thaw (P < 0.01), however SOD activity was positively correlated with the percentage of linear motile sperm post thaw (P < 0.05).
