Testosterone level is an important indicator of hormonal health. Low testosterone levels have been associated with cardiovascular disease, obesity, diabetes, decreased libido, decreased energy, and depression.1

A simple blood test is used to measure total testosterone level. Normal testosterone levels range from 300 ng/mL to 1050 ng/mL. Levels below 300 ng/dL are considered to be low. EMG also provides more information on low testosterone and testosterone replacement therapy.

Total Testosterone Level (ng/dL)


<300 Low Testosterone
300 – 1050 Normal

Detailed Explanation

The normal range for total testosterone is between 300 ng/dL and 1050 ng/dL. The range of levels considered to be normal is fairly large. One man can have a testosterone level nearly 3 times higher than another man even though both are considered normal. The change in testosterone from an individual’s baseline level is just as important as the actual clinical value. This is because a man with decreased testosterone may be symptomatic even though his new lower testosterone level still falls within the clinically normal range.

Ultimately, the diagnosis of low testosterone and the decision to pursue treatment is generally considered on an individual basis rather than simply being based on numerical guidelines for generally accepted “normal” levels.
