"Men in the highest intake group had a mean soy food intake of half a serving per day: in terms of their isoflavone content, that is comparable to having one cup of soy milk or one serving of tofu, tempeh or soy burgers every other day," said Dr Chavarro. "The implication is that men who have normal or high sperm counts may be more susceptible to soy foods than men with low sperm counts," said Dr Chavarro. Previous studies had shown Asian men to have slightly smaller testicles and lower sperm counts than non-Asian men, although it was not known whether the findings were statistically significant.
