Purpose of review: Testosterone therapy has been advocated in the treatment of symptoms that may represent normal aging. We briefly review randomized clinical trials on the effects of testosterone therapy on sexual function.
Recent findings: About half of clinical trials showed no benefit of testosterone therapy on any aspect of sexual function. In those studies showing a benefit on some aspect of sexual function, most sexual function domains were not improved. Testosterone therapy has been disappointing in the treatment of erectile dysfunction. Potential risks of therapy include an increase in thromboembolic and other cardiovascular diseases.
Summary: The limited and inconsistent benefits of testosterone therapy for sexual function argue against use of this therapy in aging men, including those with 'low testosterone'.
