Rating (out of 5): 2

Walnut (unspecified species, but most commonly Juglans regia, or English walnut) has a history of use in traditional medicine systems for supporting male reproductive health. In various cultures, walnuts have been consumed as a food believed to enhance fertility, libido, or general vitality. This may be partly due to the doctrine of signatures—the idea that foods resembling body parts can benefit those parts—with walnuts somewhat resembling the human testicle. Some traditional texts and herbal practices suggest walnuts may help with sperm production or sexual vigor.

Scientific studies are limited but provide some support: a few small human and animal studies suggest that walnut consumption may improve sperm quality and motility, likely due to their high content of polyunsaturated fatty acids, antioxidants, and micronutrients. However, these studies are preliminary and often not specific to traditional use or large-scale clinical validation. No major medical authorities recommend walnuts specifically for male reproductive health, but their general nutritional benefits are well recognized. Thus, the use of walnut for male reproductive system support is rooted primarily in tradition, with emerging but limited scientific interest.
