Eating nuts may improve sperm count, quality

The study results were presented at a meeting of the European Society of Human Reproduction and Embryology in Barcelona. 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.

Men can increase both the quantity and viability of their sperm by including mixed nuts in their daily diet, according to a new study.

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.

A total of 119 healthy men between the ages 18 and 35 were studied for the test before the researchers came to this conclusion.

He said it was that change in the level of DNA fragmentation in the sperm cells by which the researchers explained, at least in part, the improvement in sperm count, motility and morphology.

Nuts are dense foods containing many of these nutrients and other phytochemicals. The study participants who consistently consumed nuts showed notable improvements in the vitality, mobility, morphology, and the number of their sperm - factors that are all associated with male fertility. 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.

When scientists analyzed the sperm and blood samples, they found that those who ate nuts had, on average, a 16 percent higher sperm count.

The results also concluded that those who ate nuts had a "significant" fall in sperm DNA fragmentation, which is crucial for successful fertilisation and normal embryo development. This parameter is suggested as something that is often associated with male infertility.

Drawbacks to the study include that all the men were healthy, apparently fertile and eating a specific diet, Dr. Sala-Huetos noted, and that results should not be applied to the total population. "We can't yet say that", said Salas-Huetos, "based exclusively on the results of this study".

"Evidence is accumulating in the literature that healthy lifestyle changes such as following a healthy dietary pattern might help conception", Salas-Huetos writes. This study was funded by the International Nut and Dried Food Council.
