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
Hormonal disorders
Infection
HIV/AIDS
Chronic liver or kidney disease
Type 2 diabetes
Obesity

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.
