Vitamin E (alpha-tocopherol acetate) has a scientifically-supported role in supporting the male reproductive system, although the strength of evidence is moderate. Vitamin E is a fat-soluble antioxidant that helps protect cell membranes from oxidative damage. Several animal studies have demonstrated that Vitamin E deficiency can lead to testicular degeneration, reduced sperm motility, and lower fertility. In humans, some clinical studies have suggested that Vitamin E supplementation may improve sperm quality, motility, and function, particularly among men with infertility linked to oxidative stress. For example, a few randomized controlled trials have shown modest improvements in semen parameters and pregnancy rates when Vitamin E is used alone or in combination with other antioxidants. However, the results are not universally consistent, and larger, high-quality trials are needed to confirm these effects.

Historically, Vitamin E was discovered in the context of studies on reproduction; its name "tocopherol" is derived from Greek words meaning "to bring forth offspring," reflecting its role in fertility in early animal research. While the mechanistic rationale is strong—given that oxidative damage can impair sperm function—the clinical benefit in otherwise healthy men is less clear. Overall, while there is scientific evidence supporting Vitamin E’s use in male reproductive health, the benefit is likely limited to specific situations, such as oxidative-stress related infertility, rather than the general population.
