Testosterone is often considered to be a quintessential symbol of manhood and machismo. This hormone, which is produced primarily in the testicles, is associated with sexual prowess, libido, and muscle strength, but it also is critical for maintaining bone density, energy levels, and even moods. In many ways, it is the male hormone.
That’s why when testosterone levels begin to decline as men age and because of other factors such as weight gain, exposure to environmental toxins, and sedentary lifestyle, guys begin to worry. They see their sex drive faltering, their waistlines expanding, their hairlines receding, their sleep habits changing, and their get-up-and-go waning. Suddenly all those late-night ads on TV about testosterone replacement and supplements to boost T levels sound like the answer. But they are not.
