Copper-zinc superoxide dismutase deficiency impairs sperm motility and <i>in vivo</i> fertility

Abstract excerpt

Oxidative stress, overproduction of reactive oxygen species (ROS) in relation to defence mechanisms, is considered to be a major cause of male infertility. For protection against the deleterious effects of ROS, animals have a variety of enzymatic antioxidants that reduce these molecules to less reactive forms. The physiological role of these antioxidants in vivo has been explored extensively through genetic...
