Testosterone is a hormone found in men and to a lesser extent in women. It is responsible for many of the male traits and is associated with virility in men. As men get older, it is common for them to see a reduction in testosterone levels. Approximately, 15-20% of men over the age of fifty have low testosterone levels. This drop in levels for men over 50 years of age is often referred to as male menopause or testosterone deficiency. It can affect men in a number of ways, with the most pronounced symptom being high levels of fatigue and a loss of sexual interest.

Not all men that have low testosterone suffer from fatigue. Many suffer from a variety of other symptoms. One of the side effects of low testosterone is fragile bones. “Low testosterone scores often lead to drops in bone density, meaning that bones become more fragile and increasingly prone to breaks” (webmd.com). Bone fractures are a serious health concern for men, especially hip fractures. Approximately, 36% of older men that suffer a hip fracture will die within one year post fracture.

Upon confirmation of low testosterone, a person’s family physician may recommend Testosterone Replacement Therapy. There are a number of options available. Studies have provided mixed results with respect to the safety of replacement therapy. Some studies show an increased risk of heart attack and stroke due to a greater buildup of non-calcified plaque formation for those taking replacement therapy, while other studies show a decrease in these risk factors. What you see in these testosterone trials is an ominous portent of cardiovascular disease, although it remains a prediction, not a fact, said Dr. David Handelsman, director of the Anzac Research Institute in Sydney.

Exercise, especially weight training is recommended for men with low levels. In my opinion, this is only part of the equation. Diet is also a crucial factor and is definitely a contributing factor to low testosterone levels in men.
