Soy Reduces Sperm Count-New 2008 Study
July 23, 2008, last updated July 1, 2012
A new study published today in by the Human Reproduction Journal has once again linked consumption of soy with reduced sperm count.
The study, found that eating as little as half a cup of soy a day can cut your perm count in half. Soy foods contain substances called “isoflavones” which are believed to cause sperm death.
The normal concentration of sperm for fertile men is 120 million sperm per milliliter. Men who ate the highest concentrations of soy in the study were found to have sperm concentrations of only 41 million. By comparison, men with sperm concentrations of 20 million or less are considered infertile.
The study, which was conducted by researchers affiliated with the Harvard School of Public Health and Massachusetts General Hospital and Brigham and Women’s Hospital, is likely to continue to fuel the raging debate in scientific circles over the effect of soy on male fertility.
Previous studies which established the adverse link between soy consumption and sperm count were attacked by soy growers who pointed out that in Asian societies men eat far more soy in their daily diets can have no problems with fertility.
Soy is growing in popularity in American, European and other Western diets, and can be found in a wide range of products including meatless burgers (soy burgers), tofu products and is used widely in Chinese and Asian cooking.”
So it appears their could be a negative relationship between soy and sperm count: I.e., as soy intake increases, sperm count decreases. But then this is just one source.
