Researchers evaluated 891 middle-aged men with impaired glucose
tolerance and low testosterone levels who undertook a 1-year lifestyle
modification program involving 150 minutes per week of exercise and
calorie and fat reductions in their diets.
Participants had a nearly 50% increase in testosterone levels, researchers announced.
Although noting that the study reinforces existing knowledge of the
effect obesity has on blood testosterone levels, and that reversing the
excesses weight improves the effect, Dr. Handelsman cautioned that the
remedy is not testosterone treatment.
"It is important to state clearly that the lower blood testosterone
levels are not a true deficiency state; rather, they are a barometer of
ill health, as opposed to a real deficiency state," he told Medscape Medical News.
"An important implication is that such men should not be treated with testosterone."
