Walnuts

Both omega-3 and omega-6 fatty acids are abundant in walnuts. This was one of the factors that prompted researchers to wonder if they would boost fertility.

In a small research, 117 men were divided into two groups, one of which would avoid from consuming tree nuts and the other of which would consume 75 grams of walnuts daily. The men gave a semen sample before the trial started and again twelve weeks later. The sperm vitality, movement, and shape improved in the walnut-eating group after 12 weeks. After eating the walnuts, they also saw a decrease in chromosomal abnormalities in their sperm samples. There were no changes in the control group.
