Prospective studies concerning diet and male fertility are lacking. Observational studies suggest that a diet rich in fruits, vegetables and meats may be associated with higher sperm counts. The investigators wanted to see if a "paleolithic diet" consisting of meat, fish, fruits vegetables and nuts and lacking grains, legumes and dairy products can improve sperm counts.
