The Role of Testosterone Therapy in Men's Health.

Over the last 3 decades, there has been an increased interest in testosterone replacement therapy. This trend is a result of an aging population, endocrine disruptors in our foods and environment and rising obesity rates. In addition, there has been a surge in Men's Health clinics and online direct-to-consumer Web sites, making testosterone replacement therapy much more readily accessible. As more men seek to increase their testosterone levels, more long-term random control studies are needed to gain better insight into testosterone optimization to support the anecdotal observation commonly experienced in the practice setting.
