Are carrots the new sperm superfood? A study found that eating foods rich in beta-carotene can boost male fertility.

Here’s another incentive for guys to eat their fill of colorful fruits and veggies.

Researchers at Harvard University’s School of Public Health found that orange and yellow produce can increase the quantity and quality of sperm, according to a new study.

Carrots in particular were singled out for their sperm-boosting properties. These orange veggies, along with lettuce and spinach, are high in beta-carotene. Researchers found that this antioxidant improves sperm motility, or its ability to swim toward an egg, by 6.5% to 8%.

Lutein, a carotenoid or antioxidant also found in spinach and lettuce, had a similar effect on sperm motility, researchers said.

The participants with diets rich in lycopene, the chemical that gives tomatoes their red color, had lower levels of abnormally shaped sperm.

“In a population of healthy young men, carotenoid intake was associated with higher sperm motility and, in the case of lycopene, better sperm morphology,” the study says.

Researchers looked at sperm samples and diets of 189 college-age men in the Rochester, N.Y., area. The study, titled “Semen Quality in Relation to Antioxidant Intake in a Healthy Male Population,” was published in the journal Fertility and Sterility.
