Researchers at Edinburgh University have discovered a link between testosterone and diabetes with low levels of the hormone increasing the risk of diabetes among men.
The researchers revealed that low levels of testosterone were linked with an increased resistance to insulin, a hormone which controls blood sugar levels.
People who had low levels of the hormone were also at a greater risk of becoming obese, one of the major risk factors of diabetes.
The researchers conducted the test in a group of mice and found that small levels of testosterone in fat tissue were linked with greater insulin resistance. Stating that it did not matter how much an individual gained weight, lead researcher Dr Kerry McInnes said, "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."
