Weinerman added that "this study should not be interpreted as evidence that hypogonadal men [those with decreased testosterone output] should begin testosterone replacement. The risks and benefits of testosterone replacement can only be studied in larger, randomized controlled trials."
Another expert said testosterone levels may need watching as men age.
"Physicians should be checking testosterone levels in men older than age 65, discussing loss of muscle mass and potential of falls and resulting fractures," said Dr. Spyros Mezitis, an endocrinologist at Lenox Hill Hospital in New York City. "Further research is needed to define the association of low testosterone levels and decrease in physical function," he added.
The study, funded by grants from the U.S. National Institutes of Health, is slated to be published in the Journal of Clinical Endocrinology & Metabolism.
