Testosterone is the most important sex hormone that men have. It is responsible for the typical male characteristics, such as facial, pubic, and body hair as well as muscle. This hormone also helps maintain sex drive, sperm production, and bone health. The brain and pituitary gland (a small gland at the base of the brain) control the production of testosterone by the testes. In the short term, low testosterone (also called hypogonadism) can cause
• A drop in sex drive
• Poor erections
• Low sperm count
• Enlarged breasts
What causes low testosterone?
Low testosterone can result from
• Testicular injury (trauma, castration) or infection
• Radiation or chemotherapy treatment for cancer
• Some medications, such as opiate painkillers
• Hormone disorders (pituitary tumors or diseases, high levels of prolactin)
• Chronic diseases, such as liver and kidney disease, obesity, type 2 diabetes, and HIV/AIDS
• A genetic condition (Klinefelter syndrome, hemochromatosis, Kallmann syndrome, Prader-Willi syndrome, myatonic dystrophy)
How is low testosterone treated?
Testosterone replacement therapy can improve sexual interest, erections, mood and energy, body hair growth, bone density, and muscle mass. There are several ways to replace testosterone:
• Gel or patches that you put on your skin
• Anabolic Steroids Injections (shots)
• Tablets that stick to the gums
• Pellets inserted under the skin or pills (in some countries outside the United States)
The best method will depend on your preference and tolerance, and the cost.
There are risks with long-term use of testosterone. The most serious possible risk is prostate cancer. African American men, men over 40 years of age who have close relatives with prostate cancer, and all men over 50 years of age need monitoring for prostate cancer during testosterone treatment. Men with known or suspected prostate cancer, or with breast cancer, should not receive testosterone treatment.
Other possible risks of testosterone treatment include
• A high red blood cell count
• Acne
• Breast enlargement
• An increase in prostate enlargement
• Sleep apnea—the occasional stopping of breathing during sleep (rarely)
• Fluid buildup (edema) in ankles, feet and legs (rarely)
• A drop in sex drive
• Poor erections
• Low sperm count
• Enlarged breasts
