New research by scientists at the University of Edinburgh suggests that low levels of testosterone in men could increase their risk of developing diabetes.

Researchers have found that low testosterone levels are linked to a resistance to insulin, the hormone that controls blood sugar levels.

Dr Kerry McInnes, from the University’s Endocrinology Unit, said: “We know that men with low testosterone levels are more likely to become obese, and as a result develop diabetes. This study shows that low testosterone is a risk factor for diabetes no matter how much a person weighs. As men age, their testosterone levels lower. This, along with increasing obesity, will increase the incidence of diabetes.”

The study, which was funded by Diabetes UK, involved the study of mice. Dr Iain Frame, Director of Research at Diabetes UK, said: “Further work is needed to translate these initial findings into clinical practice, as it is important to emphasise that results in mice may not necessarily have direct relevance for humans.”
