This report
shows that supplementation of vitamin E was more effective
in improving sperm traits than vitamin C. These results
are in agreement with the finding of Yousef
who found that vitamin E was more effective in improving
semen quality and reduces lipid peroxidation in rabbits.
Working on cockerels, demonstrated that
vitamin E is naturally present in the sperm membrane
and seminal plasma and it can protect the sperm in two
ways. During spermatogenesis in testes, vitamin E protects
the biological membrane from lipid peroxidation.
Moreover, vitamin E can reduces the lipid peroxidation in
seminal plasma and maintains adequate viability of sperm
to complete fertilization process. Finally, dietary vitamin E
supplementation enhances sperm number and quality in
cockerels.
