When it comes to “T” levels, there are some folks that think they have it all figured out.
But do they really?
Even some well-meaning doctors and scientists don’t seem to have all their facts straight on testosterone.
Let’s take a look at some common beliefs about testosterone and determine if they are indeed fact or fiction.
When we were growing up, we were often told that testosterone was the “male” hormone and estrogen was the “female” one.
That’s simply not true.
While “T” is the major sex hormone in men, it’s also the most abundantly active steroid hormone in women’s bodies and is absolutely essential to female development.
So, contrary to what we were led to believe, men don’t have a monopoly on the hormone.
Another well-known belief about “T” is that it makes men aggressive.
While some studies have found evidence that testosterone levels are higher in people with aggressive behavior, those trials were poorly executed.
When it comes to research, I tend to put more stock in the double-blind, placebo-controlled trials – the “gold standard” studies.
And in those cases it was found that even extremely high doses of “T” don’t increase hostility, anger or aggression in men.
If you kept up with the news during the 2008 stock market crash, you may have heard a crazy tale that testosterone was to blame.
You see, some financial “experts” promoted the idea that the traders at the time, who were overwhelmingly young men, took irrational risks because of high “T” and those risks led to the crash.
That’s pure hogwash.
No conclusive, well-executed study, ever found a correlation between “T” and financial recklessness.
Ever hear that your finger size is an indication of “T” levels?
Sounds ridiculous, but this one is actually true – for men.
Research has found that in men and boys, the right pointer finger is shorter in relation to their right ring finger.
And the higher your testosterone level before birth, the lower your pointer finger-to-ring finger ratio.
Even more interesting, this has been found in other five-fingered animals, not just humans.
With “T” levels on the decline as we get older, it’s important to know all we can about the hormone and how it impacts our health.
Just as important, though, is doing your research to determine which testosterone beliefs are facts and which are pure baloney.
Stick with the facts.
