Walnuts and Sperm

Unlike most nuts, walnuts are much richer in polyunsaturated fats. These essential fats are predominantly made up of omega 3 fatty acids.

It is for this reason BBC released the article based on a study that links walnut consumption with an improved quality of sperm in men.

Eating around two handfuls of walnuts a day improves sperm health in young men, a study in the journal Biology of Reproduction suggests.


This study involved 117 men between the ages of 21 and 35, who were divided into two groups. One group added 2.6 ounces (75 grams) of whole-shelled walnuts to their daily diet.

The other group continued their usual diet but avoided eating tree nuts. Both groups ate a typical Western-style diet.

Lead author, Prof Wendie Robbins from UCLA’s Fielding School of Public Health said: “We found a significant improvement in sperm parameters in the group that consumed the walnuts.

Walnut consumption may be important for many couples since one in six couples are infertile, with 40% of these due to a male factor.

However the study suggests the small significant improvement of sperm quality may result from the fatty acids in Walnuts.

If Omega 3 does play a major role in sperm quality improvement, then it is also important to supplement with fish oil and eat plenty of fish to suffice your daily omega 3 intake if you are repulsed by the idea of walnuts.

To add to the variety of benefits of walnut consumption and its link to life changing results, Natural News points out that Walnuts prevent prostate cancer and osteoporosis.

Researchers from both the University of California, Davis, and the U.S. Department of Agriculture Western Regional Research Center in Albany, Calif., fed mice with prostate tumors the human equivalent of three ounces of walnuts a day. At the conclusion of the study, the mice’s tumors shrunk by 50 percent, and tumor growth slowed by 30 percent compared to control mice.


The benefits of a balanced omega intake are linked with protection from ageing, cancers, cardiovascular disease, arthritis, skin problems and diseases with the nervous system. Walnut consumption also lowers levels of LDL (bad) cholesterol and simultaneously raises HDL (good) cholesterol. This results in the prevention of heart disease.

Final advice: Just because a study suggests walnuts improve sperm quality or prevents cancer, it doesn’t mean walnuts will improve male fertility or stop cancer after consuming the recommended intake. There are a variety of other factors which may help improve the effectiveness of walnut benefits, such as, fruit and vegetable intake, exercise and protein intake.

A study tells one side of the story, one piece of the puzzle. The rest of the puzzle determines whether or not you will reap the full benefits from walnut consumption.
