Spontaneous lipid peroxidation and production of hydrogen peroxide and superoxide in human spermatozoa. Superoxide dismutase as major enzyme protectant against oxygen toxicity.
TL;DR: The results suggest that superoxide dismutase plays the major role in protecting human spermatozoa against lipid peroxidation, and the superoxide Dismutase activity of a fresh sperm sample appears to be a good predictor of the lifetime (up to the complete loss of motility) of that particular sample, and so may prove useful in semen analysis.

Role of glutathione peroxidase in protecting mammalian spermatozoa from loss of motility caused by spontaneous lipid peroxidation.

TL;DR: A mechanism for spontaneous lipid peroxidation in mammalian sperm is postulated which involves reaction of lipid hydroperoxide and O2 as the rate-determining step and the key intermediate is lipid hydro peroxide generated by a chain reaction initiated by and utilizing superoxide.
Journal ArticleDOI
Levels of antioxidant defenses are decreased in bovine spermatozoa after a cycle of freezing and thawing.
TL;DR: It is found that bovine spermatozoa are poorly adapted to metabolize the toxic hydrogen peroxide and the involvement of an oxidative stress during a freeze/thaw cycle is consistent with the hypothesis that ROS generated during such a cycle are detrimental to sperm function.
Journal ArticleDOI
Biochemistry of the induction and prevention of lipoperoxidative damage in human spermatozoa
TL;DR: Human spermatozoa appear to have enough anti-lipoperoxidative defensive capacity for lifetimes long enough for fertilization but still short enough for ready removal from the female reproductive tract in good time.

TL;DR: The interface between nutritional science and reproductive physiology provides considerable potential for optimizing reproductive efficiency in dairy cattle and it attempts to provide a basis for further investigation of specific mechanisms by which reproductive function is affected.
