Low Testosterone

The principal male sex hormone, testosterone, promotes secondary sexual traits including muscular growth, bone density, facial hair, and a deeper voice in addition to developing and maintaining male reproductive tissues

Although low testosterone is caused due to age, a normal range for adult males is usually between 300 and 1,000 nanograms per deciliter (ng/dL). A man is said to have low testosterone if his testosterone levels persistently fall below the lower limit of the normal range, often below 300 ng/dL.
