"Men all over Asia eat lots of soy products. They are not effeminate."

Well, they might not be effeminate but they sure ain't getting the job done.

The fall and fall of Asian fertility

"Fertility rates in East Asia have fallen catastrophically since the early 1970s and are now the lowest in the world. In all parts of Asia, the total fertility rate (TFR) has fallen by half or more in the past 35 years. In Japan, South Korea, Hong Kong, Taiwan and Singapore, the TFR hovers between 1.0-1.3. For a population to replace itself, the TFR needs to be above 2.1. Thus, if these trends in fertility are not substantially reversed, the population of Asia will rapidly shrink as the continent heads into extinction."

So has the Western world.

U.S. Births Dip To 30-Year Low; Fertility Rate Sinks Further Below Replacement Level .

I think it can be safely said that the fertility rates of the entire industrialized world have fallen drastically since the 1970s.

The Pill might have something to do with it.
