Male Reproductive Health

The American Society for Reproductive Medicine has found evidence that infertility affects men and women equally with about one-third of infertility cases being attributed to male factors, and about one-third to factors that affect women. Findings from walnut health studies have provided encouraging results regarding men’s reproductive health research and walnuts may play a role.

A study of healthy young men (ages 21-35 years), who ate 2.5 ounces of walnuts per day, experienced positive shifts in sperm quality factors, including both motility (movement) and morphology (form).1 Consuming walnuts may have contributed to shifts in certain sperm quality factors in these healthy young men, but more research is needed to understand how these findings impact the broader male population, including men in fertility clinics.
