Friday Jan 18, 2013 (foodconsumer.org) -- You and your wife have tried very hard to have a baby for a few years but you can't impregnate your wife. Your doctor tells you that you do not have any reproductive disease or disorder, but finds your sperm concentration and total sperm count are lower than normal. A new study suggests that you may have eaten too much of a high fat diet, particularly saturated fat.

The study published in the American Journal of Clinical Nutrition finds that men eating high amounts of saturated fat had 40 percent lower sperm concentration and sperm count, compared with those who had low intakes of saturated fat.

Both low sperm concentration and total sperm count can reduce the fertility of a man.

For the study, Tina K Jensen from From the University Department of Growth and Reproduction in Rigshospitalet, Denmark and colleagues analysed data on dietary fat intake and semen quality from 701 young Danish men in the general population who were examined between 2008 and 2010 to determine if they were qualified for military service.

The study found a dose-response association between intake of saturated fat and sperm quality in terms of sperm concentration and total sperm count. That is, a higher intake was linked to a lower sperm concentration and total sperm count. Specifically, men in the highest quartile of saturated fat intake had 38 percent reduced sperm concentration and 41 percent reduced total sperm count, compared with those in the lowest quartile of saturated fat intake.

A man's diet can affect his fertility and sexual life quality. Some foods and dietary supplements such as garlic, vitamin C, seafood, fish oil, zinc supplements, peanut or amino acid arginine all can boost the production of sperm and sexual drive and improve a man's sexual life as well.
