It may be a good idea for men to incorporate more omega-3 fatty acids into their diet as a new study is suggesting that a lack of the could potentially lead to infertility.

According to researchers from the University of Illinois at Urbana-Champaign, male infertility can be treated with omega-3 fatty acids. The scientists found that mice that were lacking docosahexaenoic acid (DHA), were basically infertile. However, upon introducing DHA to the mices’ diet, fertility was completely restored.

The body creates DHA from dietary acids that are found in omega-3 fatty acids, which is why adding more of the supplement to the diet could be beneficial to fertility.

“We get hints from looking at sperm in the DHA-deficient animals about what type of pathology we may be looking at and why these polyunsaturated fatty acids are important,” said Manabu Nakamura, a U of I associate professor of food science and human nutrition.

The scientists concluded that more research needs to be done in order to understand all of the benefits that come from the nutritional supplement. It has previously been discovered that omega-3 fatty acids are beneficial to heart health.
