Can men prevent diabetes with testosterone boost?
Australian men most at risk of developing type 2 diabetes are
urged to join a new study that aims to help them lose weight and
prevent diabetes - by giving them more testosterone.
The $4.8 million study, the first of its kind in the world, will
look at the potential benefits of treating men with testosterone
supplements in conjunction with a dedicated weight-loss
Up to 1500 men aged 50-74 are now being sought for this
groundbreaking studyin New South Wales, Victoria, South Australia
and Western Australia.
"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," says the leader of the study, Professor Gary
Wittert from the University of Adelaide's School of
"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.
"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."
Men who sign up for the study will have free access to the
online weight-loss program run by Weight Watchers. An online
program is ideal for men who prefer not to attend Weight Watchers
Research leader in New South Wales, Associate Professor Ann
Conway (Andrology Department, Concord Hospital) says the study,
which will be conducted over at least two years of the
participants' lives, could potentially have a range of other health
benefits for those who take part in it.
Associate Professor Conway says: "Our hope is that this study
will be a life-changing event for many men in Australia.
Older men who have developed a large belly and are at risk of
diabetes now have an opportunity to do something about their
weight, improve their lives, and provide us with all-important
research results that could benefit many others in the
