The Mediterranean diet, rich in organic vegetables, fruits, whole grains, and healthy fats, can markedly improve male fertility by increasing testosterone levels and reducing sperm DNA fragmentation.
The study designed a dietary regimen for 50 subfertile men, modifying their diets primarily with organic foods and a low-carb Mediterranean style approach, emphasized on consuming high amount of vegetables and fruits rich in various nutrients and antioxidant substances. The participants introduced whole grains, low glycemic load options, removed refined carbohydrates, ate green leafy vegetables and red fruits daily, reduced or eliminated dairy products, consumed primarily grass-fed meat and wild caught seafood, and replaced saturated fats with healthy fats such as olive oil, avocado, and nuts.
After following the modified meal plan for three months, there were considerable increases in testosterone levels observed in the subjects. Alongside this, the study also noted a decrease in sperm DNA fragmentation, particularly in individuals who reduced their carbohydrate intake by 35%. These findings demonstrate the direct effects a specifically modified diet can have on improving male fertility.
