One more argument has been found in favour of a nice cup of espresso not only in the morning. Recent studies done by Italian scholars suggest that the drink has a positive effect on male fertility. According to findings made by professors from Federico II University of Naples, caffeine in combination with the Mediterranean diet increases production of high-quality semen by 72–95%. Experts from the National Association of Andrology recommend men who plan to settle down to married life and have children to have three cups of espresso every day and not to overlook doing light physical exercises regularly and eating healthy. Specialists consider this amount of coffee to be healthy and absolutely safe.
