  • Want stronger, healthier sperm? Eat your nuts

Scientists believe regularly eating nuts could significantly improve the quality of sperm and how well the reproductive cells function.

The Spanish authors said the study results were not on their own enough to justify urging men to eat nuts if they want to conceive.

Sky News reports that the researchers' results "support a beneficial role for chronic nut consumption in sperm quality".

Sperm counts in men have more than halved over the past 40 years, a trend that has led to a raft of scientific investigations into the possible causes.

Fertility specialists in Spain examined the sperm of 119 healthy young men before and after a 14-week study during which half were randomly assigned to have 60g of mixed nuts added to their diet each day.

One group ate 60 grammes of almonds, hazelnuts, and walnuts daily on top of their usual "western-style" diet, while the second group got no nuts.

A trial found that nuts improve sperm count, vitality, swimming ability and shape - all factors that influence fertility.


The results of the study are being presented at the annual meeting of the European Society of Human Reproduction and Embryology in Barcelona.

"Moreover, the subjects in the nut group also showed a significant reduction in their levels of sperm DNA fragmentation, a parameter closely associated with male infertility".

Experts said the study backed up others that showed a diet rich in omega-3 fatty acids, antioxidants and the B vitamin folate improved fertility. The research is set to be published in the peer-reviewed American Journal of Clinical Nutrition, according to The Guardian.

The findings add to a growing body of evidence that diet has an impact on sperm and male fertility more generally.

However, researchers cautioned that these men were healthy and apparently fertile, so it was not clear whether the findings would apply to the wider population, including men with fertility problems. "Nuts are important because they are a key food for healthier life", he told Newsweek, pointing to the Mediterranean diet as a good option.

Nicholas Macklon, medical director at the United Kingdom -based London Women's Clinic fertility treatment center, who was not involved in the study, told The Guardian: "The changes are notable and likely to be beneficial for fertility".
