Benefits of Walnuts to Improve Sperm Quality

Lipid peroxidation is a process that can damage sperm cells. This form of cell damage harms sperm membranes, which are primarily made up of polyunsaturated fatty acids (PUFAs). New animal research suggests eating a walnut-enriched diet may improve sperm quality by reducing lipid peroxidation. Walnuts are the only tree nut that are predominantly comprised of PUFAs (one ounce contains 13 grams of PUFAs out of 18 grams of total fat).
