Male infertility is the cause of conception failure in up to 80% of cases, mainly due to oxidative stress and low sperm quality. An Italian study has shown that the vitamin E content in the blood of infertile men is much lower than that of fertile men. Low concentrations of vitamin E are correlated here with morphologically abnormal and less mobile spermatozoa.
Oxidative stress and insufficient vitamin E intake should therefore be avoided, especially in cases of existing fertility decline or to optimise fertility when trying to have children.
An increased intake of vitamin E can significantly increase fertility in both men and women.
Vitamin E helps to protect cells from oxidative stress.
