The normal range of testosterone levels in healthy adult males is between 280 to 1,100 nanograms per deciliter (ng/dL), reports the University of Rochester Medical Center. Itâs important to determine if a low testosterone level is due to normal aging or if itâs due to a disorder.
Now look at the average female testosterone levels: 1  12 to 16 years of age: less than 7 to 75 ng/dL. 2  17 to 18 years of age: 20 to 75 ng/dL. 3  19 years of age or older: 8 to 60 ng/dL.
