The United States found that men eating a handful of walnuts a day can improve sperm quality

According to a new study from the American Society of Reproductive Biology, men eating a handful of walnuts a day can improve sperm quality.

Researchers at the UCLA Fielding School of Public Health divided subjects into two groups. One group ate a normal diet, and the other group ate 75 grams more walnuts a day. Before and after the test, researchers extracted sperm samples from all participants and conducted comparative analyzes on sperm concentration, motility, shape and size, and chromosomal abnormalities. The results found that only the men in the "walnut group" had significantly improved sperm quality.

Dr. Wendy Robbins, the leader of the new study, said that the content of omega-3 fatty acids in walnuts is considerable. A number of male infertility studies have found that omega-3 fatty acids can improve sperm quality. This fatty acid and other polyunsaturated fatty acids play a pivotal role in improving sperm maturation and sperm membrane function.
