Over the years, the issue of testosterone supplementation has grown more controversial, according to Eric Orwoll, M.D., professor of medicine in the OHSU School of Medicine. 

A large study called the "Effects of Testosterone Treatment in Older Men" on the NIH-sponsored Testosterone Trials finally sheds light. 

In an editorial published in The New England Journal of Medicine on Feb. 18, Dr. Orwoll wrote, "Snyder et al. describe the long-awaited initial results of the National Institutes of Health–sponsored Testosterone Trials, which were designed to address the key issues identified by the IOM. Their report is important, not only because it deals with an essential public health issue but also because the investigators have succeeded in conducting the kind of generally well-conceived studies that are sorely needed in the field. The findings begin to provide a basis for more rational clinical decisions about testosterone use as well as for additional research." Read full editorial. 

Dr. Orwoll's analysis of the findings was widely covered by national media. A sampling include the Associated Press, ABC News, US News & World Report, New York Times and NPR.

Dr. Orwoll is an internationally-recognized expert in the area of bone biology and metabolic bone disease and has considerable experience in basic, clinical and epidemiological research. Major areas of research interest include the epidemiology, etiology and therapy of osteoporosis in men, the evaluation of new diagnostics and therapeutics, effects of sex steroids on skeletal biology, and skeletal genetics.
