Testosterone (T) is a hormone produced in the testicles of men (and in the ovaries of women to a much smaller amount than in men. Testosterone is often referred to as the male sex hormone. It is normal for the testosterone level to decrease in men after age 30 at a rate of 1-3% a year but men don’t develop symptoms until late 40 or early 50. During puberty, testosterone helps young boys develop male physical features like body and facial hair, i.e., a beard, and muscle strength. Testosterone is also needed to help with the development of sperm.
Low T is defined as a decrease in the blood level of the hormone, usually less than 300ng\dl plus symptoms including decrease in libido or sex drive, lethargy, changes in mood, loss of muscle mass and decreased energy levels.
The diagnosis of low T requires a medical history of symptoms, a physical exam and a blood test that confirms a decrease in the hormone level.
