WASHINGTON (AP) -- Tens of thousands of aging men are trying testosterone shots, patches and gel in hopes of regaining youthful vigor and virility. A new report uncovers little evidence it works -- or that the therapy is even safe -- but recommends careful study to find out.
"Certainly there are people out there who say testosterone replacement therapy is just wonderful, and others who say it doesn't do any good at all. What we're saying is we just don't know," said Dr. Dan Blazer of Duke University Medical Center, who led an Institute of Medicine probe of the therapy.
