The daily addition of 75 g of whole-shelled walnuts to a typical
Western-style diet appears to have positive effects on the vitality,
morphology, and motility of sperm in healthy men, according to the
findings of a randomized, parallel, 2-group, dietary intervention trial.
The authors noted that this study could not clarify whether the effects
observed in healthy adults will be applicable to those with fertility
issues. "Whether adding walnuts to the diet will go beyond the shifts in
sperm parameters as seen in this study to improving birth outcomes for
men within fertility clinic populations or in the general population is
not yet known and will require further research," the authors write.
This study was funded through a grant from the California Walnut
Commission. Dr. Lamb has received grant support from the National
Institutes of Health and from the William and Ella Owens Medical
Research Foundation.
