“Men’s sperm is in decline, and we’ve been witnessing this as scientists for quite a long time,” said Messerlian, assistant professor of environmental reproductive, perinatal, and pediatric epidemiology, in a December 2 interview on Fox News’ Tucker Carlson Tonight. “The food we eat, the air we breathe, the water we drink—our environment is having a huge impact on our reproductive capacity.”
Environmental toxins as well as chemicals in many products are to blame for declining sperm counts, said Messerlian. And men’s health in general has gotten worse, which also has an impact, she noted. “Men have gotten fatter, they’ve gotten unhealthier, men’s health is in general decline,” she said. But she added that men can make lifestyle and behavioral changes to improve their health, such as by eating more nutritious diets, curbing smoking and alcohol intake, exercising, losing weight, and choosing healthier personal care products that don’t contain chemicals such as phthalates and phenols.
