The bottom of a man’s normal total testosterone range is about 300 nanograms per deciliter (ng/dL). The upper limit is about 800ng/dL depending on the lab. A lower-than-normal score on a blood test can be caused by a number of conditions, including:
Injury to the testicles
Testicular cancer or treatment for testicular cancer
Chronic liver or kidney disease
Type 2 diabetes
Some medicines and genetic conditions can also lower a man’s testosterone score. Aging does contribute to low scores. In some cases, the cause is unknown.
A low score does not always translate to symptoms, but we often find something that’s off when we see scores of 200 or 100 ng/dL.
Even if a man does not have symptoms, he may be well advised to seek treatment. Low testosterone scores often lead to drops in bone density, meaning that bones become more fragile and increasingly prone to breaks.

About 5 million men in the United States have been diagnosed with low testosterone. A study in the International Journal of Clinical Practice figures another 12.5 million men in the United States have the hormone deficiency but aren’t receiving treatment for it. However, as testing becomes more commonplace, the number of diagnoses may be rising.
Testosterone therapy is controversial because of the potential risks of long-term treatment—and the lack of any large, extended studies that convincingly establish its safety and efficacy. Wary doctors cite what they view as overblown claims of uncertain benefits—like increased energy, heightened sex drive, and renewed vigor. They warn of underappreciated risks—such as breast enlargement, testicle shrinkage, infertility, enlarged prostate, prostate cancer, and heart attack. One randomized study of men using gel, reported in the New England Journal of Medicine, renewed debate. It was halted for safety reasons when some participants experienced cardiovascular problems, including heart attacks. However, advocates of testosterone therapy point to studies that found no connection to heart attack risk and that even suggested the treatment may promote heart health. It also has the following benefits:
Improved body composition. Reduced belly fat and more muscle are common outcomes of testosterone therapy. In a UCLA study conducted at seven U.S. medical centers and published in the Journal of Clinical Endocrinology & Metabolism, men who were given T gel therapy added 4.3 pounds of muscle in six months, and 6.5 pounds over 18 months.
Bone strength. When men are treated with testosterone, their bone mineral density increases, especially in their hips and spine. Osteoporosis is no longer considered a women’s disease; in fact, four out of 10 fractures due to brittle bones after age 50 occur in men.
Better sexual function. In a review of 17 studies in the journal Clinical Endocrinology, researchers found that an average of three months of testosterone supplementation boosted libido, increased the frequency of sex, and triggered more nocturnal spontaneous erections.
