Excessive Dietary Fat May Hinder Conception: A Link Between Man's Food Choices and Pregnancy

One reason for a couple’s inability to conceive could be linked to too much fat in the male’s diet. A study by Harvard Medical School and Massachusetts General Hospital of 99 U.S. men uncovered an association between a high fat intake and lower sperm count and concentration. Results were published in the journal Human Reproduction.
Men that consumed the most saturated fats had a 35 percent lower total sperm count and 38 percent lower sperm concentration than men that ate the least amount of such fats. Moreover, men that ate more omega-3 polyunsaturated fats—the type of healthful fat often found in fish and plant oils—had better-formed sperm than men that ate less.
