Eating fruits and vegetables with high pesticide residue decreases sperm counts by as much as 50 percent— according to researchers from Harvard University. They studied 155 men enrolled in the Environment and Reproductive Health Study. Researchers estimated pesticide levels in foods using the U.S. Department of Agriculture statistics on pesticide contamination. Men consuming more than 1.5 servings per day of contaminated produce showed lower sperm counts, abnormal sperm cells and reduced ejaculate volume. The study shows the importance of thoroughly washing fruits and vegetables before eating them.
