Just a handful of walnuts can boost male fertility
by Joshua Shoemake
“The initial research we conducted regarding walnuts and male fertility found improvement in sperm parameters after adding walnuts to the diet and has set the stage for us to further explore the impacts of walnuts on male fertility and reproductive health,” said professor Wendie Robbins of the UCLA School of Nursing.
“New projects are underway that we hope to be able to share with you in the near future,” she said. Infertility and subfertility affect a significant proportion of humanity and the burden in men is relatively unknown. Infertility is defined as a “disease of the reproductive system” and results in disability. Commenting on the study in 2012, Robbins said that 75 grams of walnuts consumed daily improved sperm vitality , motility, and morphology in a group of healthy young men between 21-35 years of age.
These findings are of particular interest to the over 70 million couples worldwide who experience sub-fertility.In fact, 30 to 50% of these cases are attributed to the male partner. Walnuts are the only nut that are an excellent source of alpha-linolenic acid.
