Fact Or Fiction: Soy Can Affect Male Fertility

A new, small study has shown that men who consume soy every couple of days have lower sperm counts than men who don’t eat soy.However, there is a debate about this study because Asian men, who traditionally eat a great deal of soy, do not appear to have any problems with their fertility. They have been having children with no difficulty for some time.

Those who refute this most recent study say that the reason for the differences in the sperm count must be attributed to some other factor, such as the high rate of obesity in Western men and normal variations in sperm counts that are seen in men.

More studies are needed to determine whether soy really affects fertility or if the lower sperm counts come from something else.
