East Asians do NOT have the lowest testosterone levels

[Mingle]

According to these studies, they have the highest. But I've also seen reports that they had the lowest and ones where they were in the middle. Based on these inconsistencies, my personal belief is that all races have more or less the same testosterone levels but can vary based on environmental factors. I'm just posting this to end the myth that Mongoloids have the lowest testosterone levels as I've seen it mentioned here several times unchallenged.

"After adjustment for age and Quetelet's index, the levels of total and bioavailable testosterone were highest in Asian-Americans, intermediate in African-Americans, and lowest in whites"

"For instance, Asian men in Hong Kong and Japan had levels of total testosterone approximately 20% higher than in other groups."

There are many factors involved in how the body uses testosterone, not just how much is available.

That's what I meant when I said that testosterone levels differ based on environmental factors rather than racial factors.

What's the genetic SNP for testosterone level?

[arkas]

There is also a lot of negative traits associated with high testosterone, does anyone really care which race on average has the highest?

Do you know if the difference in age or race is higher?

Chinese-American, and Japanese-American control men, mostly ages 60 years or older (mean age, 69.9 years) provided information on various lifestyle factors and donated an early morning fasting blood sample between March 1990 and March 1992.

Despite considerable racial and geographical differences in human phenotypes and in the incidence of diseases that may be associated with sex steroid action, there are few data concerning variation in sex steroid levels among populations. We designed an international study to determine the degree to which geography and race influence sex steroid levels in older men.

The two studies linked from the OP are about older men who are over 60 or 69.9 years old on average. Probably Asian men can preserve their sex steroid levels longer than other racial groups because they tend to live longer than any others. For instance, Japan's average life expectancy at birth is 83.7 years, while it is 71.5 years in Russia.

Russian life expectancy is low due to social/environmental factors like excessive drinking, road accidents, etc not genetic.

I've witnessed angry Mongoloids. Can confirm

[StonyArabia]

Of course they don't. They are just less hairy and have less beard. Yet however the Japanese can get beards and some body hair, well the Ainu are very hairy to be honest. Anyways one has to look Gengis Khan, Attila, the Japanese to see it's BS
