Young men who have type 2 diabetes have significantly low levels of the male sex hormone testosterone, according to a study by scientists at the University of Buffalo in the USA.
A total of 38 men with type 1 diabetes and 24 with type 2 diabetes took part in the research.
It was found that those participants with type 2 diabetes had half the amount of total and free testosterone in their blood as their type 1 counterparts.
Free testosterone is the amount of the chemical which is not bound by protein molecules that can affect bodily functions, the university notes.
Dr Paresh Dandona, professor in the department of medicine at the academic institution and senior author of the study, states that the findings have several implications apart from the impairment of sexual function in such individuals.
"The lack of testosterone during these critical years may lead to diminished bone mass and the lack of development or loss of skeletal muscle," he adds, noting that such patients may also become more resistant to insulin and also gain weight.
