US researchers recently published a report in the new issue of Reproductive Biology, saying that eating 75 grams of walnuts a day can improve the sperm quality of healthy men.
In this study, Wendy Robbins, a professor at the School of Public Health at the University of California, Los Angeles, focused on whether polyunsaturated fatty acids could improve sperm quality in men. Polyunsaturated fatty acids play a key role in sperm maturation and membrane function. Walnuts are rich in this substance.
The researchers recruited 117 healthy men between the ages of 21 and 35 and divided them into two groups. One group (58 men) did not eat woody nuts, while the other group (59 men) consumed 75 grams per day. walnut. During the experiment, their daily meals still maintained a typical Western diet. At the beginning of the experiment and after 12 weeks, the researchers analyzed the sperm concentration, viability, vigor, etc. according to the traditional male fertility parameters.
The researchers found that after 12 weeks, the levels of omega-6 and omega-3 fatty acids in the walnut group were significantly increased, and the sperm motility, vigor and morphology were improved, and sperm chromosomal abnormalities were also less. There is no change. Omega-6 and omega-3 fatty acids are two major classes of polyunsaturated fatty acids.
But the researchers also pointed out that although eating 75 grams of walnuts a day can improve the sperm quality of healthy young men, it is still unclear whether these benefits can be applied to young men with fertility problems. They plan to work with infertile couples to study daily routines. Whether the addition of walnuts in the diet can improve fertility.
