Low Testosterone


Aging in men often causes a sudden drop in testosterone. Testosterone is the male sex hormone that is responsible for giving men body and facial hair, a deeper voice, muscle strength, and the ability to produce sperm. Testosterone Deficiency Syndrome (TD) or Low Testerone (Low-T) occurs when the body is lacking an adequate amount of testosterone. The Amercian Urology Association (AUA) defines an adequate amount of testosterone as 300 nanograms per deciliter (ng/dL) and considers anything less as a deficiency.

Did You Know?

Low testosterone levels are thought to occur in 2 out of every 100 men younger than 80. In men aged 80 or older, this number jumps to almost 50 percent. Men who are obese or who have diabetes are also at an increased risk of developing low testosterone.

How is low testosterone diagnosed?

Low testosterone is diagnosed by discussing your medical history, symptoms, and current medications. Our doctor may also have you fill out a questionnaire to obtain more information and will likely perform a physical evaluation. This physical evaluation may check some of all of the following: BMI, hair patterns, the presence of enlarged breasts, the presence and size of testes, and the size of the prostate. If low testosterone is suspected, often additional testing is suggested.

To accurately diagnose low testosterone, a total blood testosterone level test is required. This is a simple blood test that will measure testosterone attached to specific proteins and free testosterone to calculate the total amount of testosterone. In some cases, our doctors may only evaluate your free testosterone levels.

How is low testosterone treated?

Low testosterone is treated by supplementing the body with additional testosterone. This can be accomplished transdermally, through injection, orally, intranasally, and with special pellets that lie beneath the skin.

Transdermal treatments are often given through topical creams, gels, liquids, and patches that allow testosterone to be absorbed through the skin for about four days. Testosterone injections are injected under the skin or into the muscle weekly, every other week, or monthly. Oral testosterone is delivered through a tiny patch that you place above your incisor tooth for 12 hours. Intranasal testosterone is a gel that is delivered through the nose three times a day. Finally, testosterone pellets are placed under the skin every 3-6 months at the upper hip or buttocks. The exact treatment you decide upon will depend on a number of factors and our doctors will help you find the testosterone treatment that is right for you.
