Soy-based foods may lower sperm count: study

Finally an answer to the question, "Why Are There So Few Chinese/Japanese?"

"Eating a half serving a day of soy-based foods could be enough to significantly lower a man's sperm count, U.S. researchers said on Wednesday...

Chavarro said the study was not sufficient to suggest that soy intake would have health implications such as inducing infertility. Much bigger studies would be needed to answer that question, he said."

How about Asia? Is that big enough?

Brilliant!
