Two widely reported studies showed a link between low testosterone and heart attacks in diabetics. This does not mean that low testosterone was the cause of the heart attacks (International Journal of Impotence Research, July 2006). It is more likely that diabetes damages arteries to cause heart attacks and it also damages the testicles to cause a low testosterone.
Men with low testosterone are far more likely to store fat primarily in their bellies, which means they also store fat in their livers. This interferes with the liver's ability to remove insulin from the bloodstream after it has done its job of driving insulin from the bloodstream into cells. These people develop high blood sugar levels which causes sugar to attach to the surface of cell membranes, in this case on the testicles, and damage them to cause low levels of testosterone.
If you are a man who stores fat primarily in your belly, check with your doctor to get blood tests for cholesterol and diabetes (HBA1C), and check for high blood pressure. If your HBA1C is high, you are diabetic and should immediately start a diet that is low in refined carbohydrates, lose weight and see if it is safe for you to start an exercise program.
