Daily Walnuts May Improve Sperm Quality, Study Finds

Sperm quality may be improved by daily walnut consumption, a new study funded in part by the California Walnut Commission has revealed.

Yes, tempting puns abound when discussing the benefits of walnuts on sperm quality, but we shall forgo them all and note that if you are planning to start a family, perhaps you might want to make a trip to the bulk nuts section of Whole Foods on your next shopping foray.

It seems that consuming what seems to be a rather high quantity of walnuts — about half a cup a day for 12 weeks — precipitated a marked increase in quality of sperm in study participants. Among the group of men who consumed the walnuts daily during the course of the study, sperm were observed to have better shapes, be more motile, and overall be more vital.

In the study, 58 healthy men between the ages of 21 to 35 were asked to eat the daily walnut dose,while a further 59 men were advised not to consume tree nuts. After the results were published, Dr. Allan Pacey, senior lecturer in andrology at the University of Sheffield, commented:

“It would be relatively easy to poke fun at studies like this, but there is increasing evidence to show that aspects of a man’s diet can affect the number and quality of sperm produced by his testicles.”

Subfertility or infertility affects more than 70 million couples worldwide, and 30 to 50 percent of the cases are believed to stem from issues with male fertility. The study appeared in the August 15 edition of Biology of Reproduction.
