What happens when a man's testosterone levels drop?

Harris H. McIlwain, MD

As the testosterone level gets lower the libido or sex drive drops, and fatigue is common. Depression can happen, perhaps as a result of these unwanted changes. When low sex drive and fatigue happen in men, it is worthwhile to check a blood level of testosterone.

The libido can be greatly helped by giving testosterone treatment. Testosterone is important for maintaining muscles, so as levels of this much-needed male hormone decrease, there may be a drop in muscle size and strength. There can also be hair loss, irritability, and forgetfulness.

Low testosterone levels can also lead to osteoporosis, which is thinning of the bones.  Osteoporosis is more famous as a disease in women , but in fact, 20 to 25 percent of cases happen in men. Low testosterone levels are common in osteoporosis in men.
