Roles of Antioxidants on Prolonged Storage of Avian Spermatozoa In Vivo and In Vitro
TLDR
Dietary supplementation with vitamin E is effective in limiting lipid peroxidation of sperm plasma membranes, both in chickens and turkeys, and organic Se with or without vitamin E stimulates Se‐GSH‐Px activity in seminal plasma.Abstract:
This review focuses on natural and assisted prevention against lipid peroxidation in avian spermatozoa. The presence of high levels of n-6 polyunsaturated fatty acids (PUFAs) in the plasma membrane creates favorable conditions for the formation of peroxidative products, a major cause of membrane damage which may ultimately impair male fertility. However, a complex antioxidant system involving vitamin C, vitamin E and GSH is naturally present in avian semen. Coupled with a battery of enzymatic defenses (e.g., SOD, GSH-Px either Se- or non-Se-dependent), this system acts to prevent or restrict the formation and propagation of peroxides. The presence of specialized sites dedicated to prolonged sperm storage in avian females raises the question of durable protection of sperm membranes against peroxidation. Preliminary observations have revealed the presence of a specific antioxidant system at these sites in which vitamin C could exert a major role. From a practical standpoint, the extensive use of artificial insemination in poultry, along with the emergence in some species of workable techniques to cryopreserve spermatozoa, demand better control of peroxidation occurring in the plasma membrane of spermatozoa before or during storage. Dietary supplementation with vitamin E is effective in limiting lipid peroxidation of sperm plasma membranes, both in chickens and turkeys. In addition, organic Se with or without vitamin E stimulates Se-GSH-Px activity in seminal plasma. Preliminary observations in female chickens have also revealed the effectiveness of dietary supplementation with vitamin E, organic selenium or both to sustain fertility in aging flocks.read more

Effect of selenium and vitamin E addition to the extender on liquid stored capercaillie (Tetrao urogallus) semen quality.
TL;DR: It is concluded that selenium and vitamin E addition to EK extender had positive effect on morphology and motility of capercaillie semen stored 24 hr at 4°C and can be recommended for similar studies carried out on other Galliformes species.

TL;DR: The findings reveal that the long-term storage of sperm and the maintenance of their function in the female reproductive tract require an adequate microenvironment.

Antioxidant status of the lower oviduct in the chicken varies with age and dietary vitamin E supplementation.
TL;DR: It is concluded that the chicken UVJ provides a complex defense barrier against lipid peroxidation of the sperm membrane during in vivo storage, which can be partially improved by dietary supplementation with vitamin E.

TL;DR: The data suggest that ROS induce a chain of events leading to sperm immobilization, that axonemes are affected, and that limited endogenous repair mechanisms exist to reverse these damages.

Juan G. Alvarez,Bayard T. Storey +1 more
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.

TL;DR: A difference in both composition and thermotropic phase behavior of glycolipids between rooster and mammalian sperm is demonstrated which may be related to the greater tolerance of rooster sperm to rapid cooling.

Lipid peroxidation in human spermatozoa as related to midpiece abnormalities and motility.
TL;DR: The results suggest that poor motility is linked with membrane fragility and that spermatozoa with midpiece abnormalities probably have membrane and/or cytoplasmic antiperoxidant system defects.
