Benefits and Risks of Testosterone Therapy

Benefits and Risks of Testosterone Therapy


The latest of many studies aimed at challenging the anti-aging claims of popular supplements found that while testosterone gel does not improve memory or mental function for men, there are mixed results for other potential benefits.

According to the AP (2/21, Tanner), four National Institute of Health-funded testosterone trials published in JAMA (The Journal of the American Medical Association) reported the effects of testosterone gel on nearly 800 US men 65 or older. The group of 800 men were randomly selected to either rub testosterone gel on their skin daily for one year or to to do the same with a non-testosterone gel.

After a year, the testosterone treated men did not show any improvement in memory or mental function, but they did show an increase in bone density and strength, especially in the spine, compared to those who were treated with the non-testosterone gel. The testosterone treated men reported having more energy and those with anemia showed vast improvement after one year. However, the men treated with testosterone gel also reported to having more plaque build up and narrower arteries. CNN (2/21, Scutti) reported that in a separate study published by JAMA, testosterone therapy was found to be associated with a lower cardiovascular risk in men over 40 for a period of about 3 years.
