Daily Intake Of Walnuts Boosts Sperm Health

Young men who eat 75 grams of walnuts – about two handfuls – a day improve the health of their sperm, a new U.S. study reports. The news offers hope to the 70 million or so couples who are experiencing subfertility or infertility worldwide. Thirty to 50 percent of the cases can be traced to the male partner. For the study, 117 healthy men between the ages of 21 and 35 either avoided eating tree nuts, or ate 75 grams of walnuts each day for 12 weeks. Tests of the sperm in both groups found that those who ate walnuts had improved sperm quality: greater vitality, motility, and morphology.
