The determination of sperm cryotolerance is an important step in the process of developing optimal techniques for the storage of boar semen. The objective of this study was to determine individual proteome variations in boar seminal plasma and spermatozoa and establish their influence on the cryotolerance of ejaculate. Sodium dodecyl sulfate polyacrylamide gel electrophoresis revealed the presence...
The antioxidant system in semen is composed of enzymes, low-molecular weight antioxidants and seminal plasma proteins. Loss of enzymatic activity of superoxide dismutase (SOD) during semen preservation may cause insufficient antioxidant defense of boar spermatozoa. The aim of this study was to isolate and characterize SOD molecular forms from spermatozoa and to describe changes in SOD activity in...
