Eating nuts increases the quality of sperm, Spanish study finds

Eating nuts increases the quality of sperm, Spanish study finds

Nuts are dense foods containing many omega-3, antioxidants (vitamin C and E, selenium and zinc), and folate and other phytochemicals.

"We can't yet say that", Dr. Albert Salas-Huetos from the Human Nutrition Unit of the Universitat Rovira i Virgil in Reus, Spain said, "based exclusively on the results of this study".

This was a randomized trial where sperm parameters were measured in the study participants over a 14 week study.

Although these are statistically significant results from a randomised trail with a high level of scientific evidence, Salas-Huetos emphasised that subjects in the study were all healthy and apparently fertile men following a western-style diet. The results of the research was presented at the 34th Annual Meeting of ESHRE in Barcelona showed that a nuts-rich diet could boost sperm count by nearly 20 percent, the vitality of sperm cells by 5 percent, their mobility by six percent and the shape and size of sperm cells by one percent.

All over the world, cases of infertility are rising.

The 14-week study involved 119 men aged 18-35.

The study "supports a beneficial role for chronic nut consumption in sperm quality" and reflects a need for further investigations into male-specific dietary recommendations, he said.

A diet rich in nuts can boost sperm count by 20%.


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

"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.

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

Dr Albert Salas-Huetos said the study was performed amid a general decline in the quantity and quality of sperm that men are producing. At the molecular level it has also been proposed that the genetic integrity of each sperm cell is essential for successful fertilisation; if DNA strands in the cell become damaged or fragmented, they will be unable or less likely to fertilise an egg and maintain embryonic development.

Morphology - the size and shape of sperm - increased by 1 percent.

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.

"We can't yet say that based exclusively on the results of this study", Salas-Huetos said. A handful of nuts every day will go a long way in improving male fertility.
