The history of synthetic testosterone

Article Abstract:

The use of testosterone and its anabolic steroid derivatives by athletes as performance-enhancing substances is well-known, and this tends to overshadow the promising medical benefits of male hormone therapies. A history of such therapies is presented, along with predictions about future developments.
