Mats, are you saying that low levels of Testosterone causes low facial hair growth?! In other words, I have low growth rate of my facial hair and I can not grow a "real" mustache: so do you suggest that I have to do testosterone test.
One last point; is it ((common)) that people of low facial hair growth have normal or high levels of testosterone?!
No, there's no direct correlation between testosterone levels and facial hair growth. There is an indirect correlation, in that without any testosterone, or extremely low levels of testosterone, there will also be low levels of FSH, and thus little to no facial hair growth. But you would only notice this under extreme cases of low testosterone that would have many other side effects besides just little to no facial hair.
So basically, just because someone has a light beard or little body hair does not mean their testosterone levels are low. In fact, they could even be higher than someone who has a thick heavy beard and is hairy all over.
Asians for example, typically have very light beards, and hardly any body hair. Looking at the population of China, there is definitely no problems there with low testosterone!
