The National Health and Medical Research Council (NHMRC) is bankrolling a $4.8 million study in Australia to test whether men can shed pounds and prevent diabetes through testosterone supplements, coupled with a dedicated weight-loss program through Weight Watchers.
"We know that as men get older and gain weight—especially when they become large around the belly—they often suffer from reduced testosterone levels," the leader of the study, Professor Gary Wittert from the University of Adelaide's School of Medicine, told newswise. "Lower testosterone has many implications for men's health, such as reduced motivation to exercise and lack of sexual function. It is also closely associated with type 2 diabetes, which is an enormous health burden for Australia."
Researchers are currently recruiting up to 1,500 Australian men, ages 50-74, most at risk of developing type 2 diabetes, to participate in the two-year study, known as T4DM (Testosterone 4 the prevention of Diabetes Mellitus).
"By giving testosterone supplements to men in that critical pre-diabetes stage, and by putting them on a dedicated weight-loss program, we expect to see sustained reductions in weight and a reduced chance to develop type 2 diabetes."
