Eating a walnut-enriched diet with 75 grams of walnuts every day may improve sperm vitality (movement) and morphology (form) -- markers of semen quality, which is a predictor of male fertility -- in men who added walnuts to their diet compared to men who did not, a study has found.
The findings showed that mice that consumed a diet containing 19.6% of calories from walnuts (equivalent to about 2.5 ounces per day in humans) had significant improvements in sperm quality by reducing lipid peroxidation -- a process that can damage sperm cells.
