Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Vitamin E has been studied for its role in supporting the male reproductive system, particularly in the context of fertility. As a potent antioxidant, Vitamin E helps protect cell membranes from oxidative damage, which is relevant since sperm cells are particularly susceptible to oxidative stress. Some clinical studies have investigated the effects of Vitamin E supplementation on male fertility parameters such as sperm motility, morphology, and overall count. For example, a few randomized controlled trials have found modest improvements in sperm motility and a reduction in sperm DNA fragmentation among men with infertility who received Vitamin E, often in combination with other antioxidants like Vitamin C or selenium. However, results are inconsistent, and not all studies have demonstrated a clear benefit.

Traditional uses of Vitamin E for male reproductive health are limited, and its application in this context is primarily based on scientific rationale rather than established historical practice. Despite some positive findings, the overall quality of the evidence is moderate at best. Major guidelines do not universally recommend Vitamin E supplementation for male infertility, except possibly in selected cases of oxidative stress-related infertility. Therefore, while there is some scientific basis for Vitamin E’s use in supporting male reproductive health, the evidence is not strong or conclusive, warranting a moderate rating.
