Eating nuts can improve sperm health in men, suggests a study from the Universitat Rovira i Virgil in Reus, Spain. The research was presented at the European Society of Human Reproduction and Embryology's annual meeting in Barcelona.
The study involved 119 healthy men ages 18 to 35, who were randomly divided into two groups. One group added 60 grams (about a handful) of nuts – almonds, hazelnuts, and walnuts – to their regular Western-style diet each day; the second group didn’t add nuts to their diet. Researchers collected sperm samples and blood samples from study participants at the beginning and the end of the study period.
The men who added nuts to their diet experienced 16 percent higher sperm counts, 4 percent higher sperm vitality (the number of live, healthy sperm cells found in semen), 6 percent improvement in sperm motility (sperm cells' ability to move), and 1 percent improvement in sperm morphology (sperm cells' normal, healthy, size and shape). They also showed less sperm DNA fragmentation – a marker that indicates reduced fertility and increases miscarriage risk.
