Low testosterone levels in men have been blamed for everything from erectile dysfunction to cardiovascular disease. Is testosterone the fountain of youth that can reverse the age-related decline in physical fitness, as well?
Well, the science suggests that testosterone may just be the scapegoat for overall declining health in aging men. That is, declining testosterone may be a marker for ill-health, not the cause of ill-health per se.
In fact, lifestyle changes are just as effective as testosterone replacement therapy for physical decline that has been blamed on low testosterone levels in men.
Nonetheless, the use of testosterone replacement therapy for combating the ill-effects of aging has become the latest craze among even middle-aged men who are looking to regain the physical fitness and energy levels that they experienced in their younger years.
And while there do appear to be benefits to a man’s physical fitness by reversing the natural decline in testosterone, scientists consistently warn against its universal prescription for this purpose.
Here’s how the science currently looks:
Naturally declining testosterone levels, and low testosterone levels in men have been associated with many physical fitness complaints, such as the following:
However, low levels of testosterone may not be causing these disease states and increased risks, but rather, are another symptom in the bigger picture of aging and ill-health.
That is, the science does not clearly say whether the testosterone levels are merely correlated with these adverse experiences, or are specifically causing them (1).
Studies have shown that replacing testosterone through hormone therapy can reverse some of the ill-effects seen with low testosterone levels in men, including improving muscle mass and strength, and reducing fat mass (2,3,4).
studies also show that elderly men can improve physical function with comparable results
to hormone replacement therapy by following an exercise program (4). The
fundamental problem with exercise treatment is that many men fail to comply
Therefore, the scientists’ conservative position discouraging widespread prescription of testosterone therapy seems particularly well-suited to complaints of declining physical fitness that can be sufficiently addressed through improved exercise regimens.
appears to be an example of patients (and physicians) choosing an
apparent "easy way out" with a pill, rather than committing to an
exercise program that will garner similar results. If you, too, are
considering the "magic pill," make sure you head over to this page to see the potential side effects and other considerations of testosterone replacement therapy.
