When Do Men Need Testosterone Supplements?

Low testosterone levels make men feel rotten! Symptoms include fatigue, depression, loss of energy, decreased sex drive, abdominal obesity, poor blood sugar regulation and erectile dysfunction. Low blood levels of total testosterone are not enough to warrant testosterone supplements— according to Shehzad Basaria from Harvard Medical School. Diagnosis requires two separate measurements of total testosterone, measurement of serum hormone-binding globulin and free testosterone to determine if symptoms are due to low testosterone levels or something else. The normal range for total testosterone is 300 to 900 nanograms per 100 milliliters of blood. Many anti-aging specialists believe that middle-aged and older men should have testosterone levels of 800 to 900 for optimal health and well-being.
