Protein on Fertility

There was a study that mice on a high protein diet were less fertile than mice on a normal diet. But, do not worry because the reproductive cycle of a mouse is different from a human being.
Just avoid any diet that excludes an entire food group or puts too much emphasis on one type of food. Instead you must have two to four servings of up to 3 ounces of protein a day, including fish, lean meats, nuts, and legumes.
