I've wondered about the effect that environmental factors might have on Japan's current predicament- something in the water? did processing of soy products change at some point such that levels of the estrogen analogs ended up being higher? I guess I haven't been quite curious enough to see if there have been any rigorous studies that have compared T levels there over the last few decades.
