Nut consumption significantly improves the quality and function of sperm in healthy men, suggests a new study.
On the other hand, a second study in men diagnosed with fertility problems on sperm health – contrary to the results of previous works
The studies were presented at the conference of the European Society of Human Reproduction and Embryology (ESHRE) in Barcelona, Spain, last week.
Daily snack of a mixture of almonds Dr. Albert Salas-Huetos of the Universitat Rovira i Virgil de Reus, Spain, said: "Hazelnuts, walnuts and walnuts s & rsquo; Add to a general western diet, resulting in a 16% increase in sperm count, as well as better vitality, motility and sperm morphology. 19659003] He said that it was too early to say that men who were trying to have a baby should add nuts to their diet. "But the evidence is piling up … as healthy lifestyle changes, such as following a healthy diet could help with conception – and, of course, nuts are a key part of a diet." healthy Mediterranean, "he said. nutrients, including zinc, selenium, omega-3 and folate, which have been shown by previous studies to improve sperm health.
Dr. Albert Salas-Huetos and his colleagues randomly selected 119 healthy men, aged 18 to 35, to follow their usual diet with or without a daily supplement of 60 grams of mixed nuts for 14 weeks. The nut group has not only shown an improvement in sperm parameters badociated with fertility, but also a reduction in sperm DNA fragmentation badociated with male infertility.
Dr. Salas-Huetos indicated that the study was conducted Therefore, the results can not necessarily be extrapolated to the general population. The research was funded by the International Nut and Dried Food Council.
Professor Allan Pacey of the University of Sheffield, who was not involved in the research, said the strength of the study was its random and controlled design. However, he noted that this was not "blinded".
"It seems to me that if you were randomized to nut eaters and you get nuts, you would know it," he said. "There are a lot of confusing factors that could have slipped into the equation, like the men who eat nuts knowing that and also changing other aspects of their lives." [19659003] The second study found that there were 174 couples in the man. a daily antioxidant supplement did not make any difference in sperm concentration, motility or morphology, nor in DNA fragmentation after three months. All men in the US trial had a diagnosis of male infertility
The study authors stated that previous work showing that antioxidants could improve sperm quality were limited by small numbers and various patient groups, among other factors. "The results do not support the empirical use of antioxidant therapy for male infertility in couples who are trying to conceive naturally," said the author of the study, Professor Anne Steiner at the University of North Carolina at Chapel Hill.
