Men who ate about two handfuls of mixed almonds, hazelnuts and walnuts daily for 14 weeks improved their sperm count and had more viable "swimmers", scientists found.
For the 14-week study, 119 healthy young men aged 18 to 35 were randomly assigned to two groups. One ate a normal western diet, while the other consumed the same diet with 60 grams per day of mixed almonds, hazelnuts and walnuts.
Comparing the two groups showed that men who had nuts added to their diet had a 16% higher sperm count, while their sperm vitality was improved by 4%, motility – swimming ability – by 6% and morphology（shape and size）by 1%.
Nuts are rich in omega-3 fatty acids, antioxidants and folate, which in other studies have also been found to benefit sperm. However, the potential benefits of nuts for men struggling with fertility have yet to be probed.
