Abstract

Several studies have shown that the oxygen can give rise to several reactive species (ROS) which, in contact with the plasma membrane of spermatozoa, attack the chain polyunsaturated fatty acids present in the membrane and triggers the process of lipid peroxidation. Oxidatives lesions can change the fluidity of sperm membrane compromising the performance of spermatozoa in fresh semen and cryopreserved. Animals can use enzymatic antioxidants or natural antioxidants such as vitamins E and C to minimize the effects of lipid peroxidation in  spermatozoa. The objective of this work is to discuss how the oxidation process affects the performance of the spermatozoa and the antioxidant properties from vitamins and minerals on the metabolism of mammalian spermatozoa.
