Testosterone levels in men decline with age, at a rate of about 1% per year beginning at about 40 years old.3 Epidemiological studies have determined that total testosterone follows an age-related decline with mean serum concentration at the age of 75 years approximately two thirds that at 25 years.4

According to reports, approximately 74% of chronic opioid users5, 50% of AIDS patients6, 52% of obese men7, 50% of diabetic men7,8 have low testosterone.

Other causes of lowered testosterone levels include: injury, infection, or loss of the testicles; chemotherapyor radiation treatment for cancer; genetic abnormalities such as Klinefelter's Syndrome (extra X chromosome); hemochromatosis(too much iron in the body); dysfunction of the pituitary gland; inflammatory diseases such as sarcoidosis (a condition that causes inflammation of the lungs); chronic illness; chronic kidney failure; liver cirrhosis; stress; and, alcoholism.
