Walnuts Boost Sperm Health

Attention, nut lovers (pun not intended): Eating walnuts boosts sperm health. Adding walnuts to your unhealthy diet can help improve the quality of your swimmers. Apparently, eating nuts improves the health of your own nuts (pun intended).

According to a 2012 study on walnuts and semen quality, adding 75 grams of walnuts to your daily diet keeps your sperm healthy. Your sperm’s swimming power and appearance are boosted when you chomp on just a few pieces of walnuts every day.

Walnuts Help Sperm – Why?

Walnuts help sperm, but why exactly? Read on to find out.

Walnuts are rich in polyunsaturated fatty acids – call them PUFAs if you want to prevent a nosebleed – such as omega-3 fatty acids and omega-6 fatty acids. Although the relationship between PUFA levels and sperm health was not established, one thing’s for sure: men who eat at least 75 grams of walnuts have much better swimmers.


About 120 healthy men with no food allergies were included in the study. Those who have had their tubes cut were excluded, as were the men who are currently taking antioxidant supplements and other medications. That way, extraneous factors are eliminated and any improvement in sperm health can be more clearly attributed to walnut consumption.

Men who eat unhealthy fast food showed a great response to the addition of walnuts to their diet. Perhaps walnuts made up for the lack of micronutrients, boosting semen health.

Will Walnuts Help Treat Male Infertility?

But does a walnut-enriched diet help men with fertility problems? Perhaps, but more research is needed before a conclusion can be reached. After all, the above study involved men with good reproductive health. Only those without fertility problems were enrolled in the study.

But that’s where it all starts. We need to establish norms before we can start exploring what lies beyond them. If walnuts help improve semen quality in healthy men, it’s a finding that encourages further research on the role of one’s diet in treating infertility.

It goes to show that what you eat plays a vital role in your overall health. Stop munching on junk. Stock up on yummy fruits instead. Eat healthy; buy some walnuts – your sperm will thank you for it.
