About Low Testosterone

Testosterone is the most important sex hormone in the male body. Testosterone is responsible for development of male characteristics such as body and facial hair, muscle growth and strength and a deep voice. Normal levels of testosterone also influence the production of sperm, promote sexual function and promote sex drive.

We now know that some men’s bodies do not make enough testosterone, resulting in a condition called hypogonadism or low testosterone (low T). These men may experience uncomfortable and sometimes distressing symptoms. The U.S. Food and Drug Administration (FDA) estimates that 4 to 5 million American men may suffer from low T, but only 5 percent are currently treated.

As men get older, the ability to produce testosterone declines. Studies show that men lose testosterone at a rate of 1 to 2 percent a year after age 30. If testosterone levels fall below the normal range some typical symptoms may include:

If you experience symptoms associated with low T, you may want to ask your doctor about getting your testosterone levels checked. A primary care physician can check your testosterone levels with a simple blood test to determine if you have low T and whether testosterone therapy is right for you. You might also ask your primary care physician about a referral to an endocrinologist or urologist who specializes in treating conditions such as low T.

If you do experience symptoms of low T and are diagnosed by a physician, the good news is that the condition very often is treatable. There are several FDA-approved testosterone replacement therapies, including:

Testosterone therapy is not for everyone. Please talk to your doctor about which therapeutic option may be best for you.

Testosterone therapy should not be used in men with carcinoma of the breast or known or suspected carcinoma of the prostate.

Geriatric patients treated with androgens may be at an increased risk for the development of prostatic hyperplasia and prostatic carcinoma.
