Eating nuts may improve sperm quantity and vitality

Eating nuts may improve sperm quantity and vitality

The study was run in the Human Nutrition Unit of the Rovira i Virgili University in Spain, by lead author Dr Albert Salas-Huetos.

The trial involved measuring conventional semen parameters and molecular changes over a 14-week period.

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 young men who ate nuts were found to have "significant" improvements in their sperm count, vitality, movement and shape, consistent with improvements found in other recent studies with diets rich in omega-3, antioxidants and folate.

About one in seven couples have difficulty getting pregnant and about 40-50% of cases of infertility are attributable to men.

119 men age 18-35 years, participated in the experiment consumed in your diet of 60 grams of nuts: hazelnuts, almonds and walnuts.

Although the findings support hopeful fathers adding nuts to their diets, the researchers stress the study was carried out on healthy men who ate a western diet and therefore the results may not apply to all. Their sperm vitality rose by 4 percent while their sperm motility - the ability to move independently - increased by 6 percent.

However, Salas-Huetos said more research needs to be conducted before men start adding nuts to their every day diet in hopes of increasing their chances of conception.

"Including nuts in a regular diet significantly improved the sperm count, vitality, motility, and morphology, partly explained by a reduction of the DNA fragmentation", scientists wrote in a release.

Sperm and blood samples were analysed at baseline and after 14 weeks of intervention.

The study recorded not just sperm parameters but also changes in several molecular factors, including sperm DNA fragmentation.

Dr. Salas-Huetos pointed out that the results of the study can not necessarily be applied to the general population, considering that the male subjects were all healthy and fertile men who followed a western-style diet.

"We can't yet say that based exclusively on the results of this study", said Dr. Salas-Huetos.

In addition, the participants were obviously aware of whether they were in the nut-eating group or not and may have made other changes to their lifestyle that boosted their sperm's health.
