Study: Walnuts a Potent Fertility Booster

Friday, 17 Aug 2012 02:59 PM

Walnuts are a potent fertility booster for men.
That’s the key finding of new research out of the University of California-Los Angeles that determined eating a pack of walnuts a day improves the “vitality, motility, and morphology of sperm” in healthy young men. The findings, published in the journal Biology of Reproduction, indicate men who ate 2.5 ounces of walnuts per day experienced the greatest benefits.
Lead researcher Dr. Wendie Robbins noted polyunsaturated fatty acids (PUFAs) – found in walnuts, flax seed, fish, and fish oil supplements – are critical for sperm maturation and function. Walnuts are also a rich source of omega-3 and omega-6 fatty acids. So she and her colleagues sought to determine if increasing their levels in healthy young men could boost their fertility.

For the new study, supported by the California Walnut Commission, Robbins’ team recruited 117 healthy men between the ages of 21 and 35 and divided them into two groups: about half avoided eating tree nuts and the other half ate 75 grams of walnuts per day
The men's semen quality was analyzed before and after the study, according to conventional parameters of male fertility, including sperm concentration, vitality, motility, morphology, and chromosome abnormalities.
After 12 weeks, the team men consuming walnuts had significantly increased levels of omega-6 and omega-3 (ALA) fatty acids and experienced improvement in sperm vitality, motility, and morphology, compared to those who didn’t eat nuts. They also had fewer chromosomal abnormalities.
About 70 million couples experience fertility problems worldwide, with up to 50 percent attributable to the male partner. Some studies have suggested that human semen quality has declined in industrialized nations, possibly due to pollution, poor lifestyle habits, and/or an increasingly Western-style diet.
Previous studies have found walnuts are packed with nutrients, antioxidants and vitamins that are good for the brain, heart and nervous system. They’re about 20 percent protein, loaded with omega-3 and omega-6 fatty acids and contain vitamins E and B6.
