What are common symptoms of low testosterone?
In men, the symptoms of low testosterone range from decreased sexual thoughts, erectile dysfunction, increased body fat, muscle aches and decreased muscle mass to anxiety, depression, lack of motivation, excessive sleepiness, and fatigue (especially in the afternoon.)
Many of the above complaints may be caused by other disease processes, but checking a testosterone level is prudent as men lose about 1% of their testosterone every year starting at the age of 30. In addition, other chronic diseases may further lower testosterone levels.
If a man’s level comes out “normal” please know that different doctors and different laboratories have different ideas about what “normal” testosterone levels actually are, and make sure a free testosterone level is also tested.1
