title: Superoxide dismutase in human semen.
abstract: Amounts of Copper/zinc containing superoxide dismutase have been found in human seminal plasma. Superoxide dismutase inhibits the lipid peroxidation in the xanthine oxidase system. In seminal plasma of spermatozoa with a good motility the superoxide dismutase activity is higher than in those with a low motility.
