  • Diet rich in nuts may boost sperm count motility By IANS On Jul 4 2018- 20:51:26 Share

The team believe that could be because nuts are rich in omega-3, folate and antioxidants such as selenium, vitamin C and E, and zinc.

The results, presented at the 34th Annual Meeting of ESHRE in Barcelona, showed that a diet rich in nuts can boost sperm count almost 20 per cent, sperm vitality almost five per cent, sperm motility by six per cent, and morphology by one percent. In its analysis the study recorded not just sperm parameters (according to World Health Organization benchmarks) but also changes in several molecular factors, including sperm DNA fragmentation.(3) Sperm and blood samples were analysed at baseline and after 14 weeks of intervention.

Although these are statistically significant results from a randomized trial with a high level of scientific evidence, Salas-Huetos emphasized that subjects in the study were all healthy and apparently fertile men following a western-style diet.

The experiment divided 119 healthy men between the ages of 18 to 35 into two groups, with one adding the two handfuls of mixed nuts to their diet and followed for 14 weeks.

The results "support a beneficial role for chronic nut consumption in sperm quality", the researchers said in a meeting of the European Society of Human Reproduction and Embryology in Barcelona.

Improvements in the former group were by around 16 per cent in sperm count, four per cent in sperm vitality, six per cent in sperm motility, and one per cent in morphology.


So should men hoping to conceive a baby - either naturally or with IVF - add nuts to their everyday diet?

Maybe, says study author and nutrition expert Albert Salas-Huetos. Reduction in DNA fragmentation was the main reason why the other parameters also improved he said. For the analysis, the researchers recorded not only the quality of the sperm but also the changes that occurred in several molecular factors, including sperm DNA fragmentation.

As well as improvements in sperm count and shape, the researchers examined the quality of DNA inside the sperm.

Any nut would be useful in the prevention of male infertility.

"The fact that the study has taken place is good", said Virginia Bolton, a consultant embryologist at Guy's and St Thomas's hospital in London, "but we need to see this translated into an effect on fertility". Trial participants who knew they were eating nuts might have changed other aspects of their lifestyle, which could have skewed the results.
