Many effects of diabetes are similar across the sexes. The condition causes damage to blood vessels and nerves.
However, the main differences when diabetes occurs in men are the following:
Erectile dysfunction: Up to 75 percent of men who have diabetes experience difficulties achieving or maintaining an erection. Nerves and blood vessels are vital to the process of an erection, and damage to these systems can impact the workings of the penis.
Genital thrush: Men can experience repeated cases of genital thrush, a fungal yeast infection. Excess sugar in the blood gets passed in the urine. However, yeast thrives on sugar and is more likely to grow on the penis of a man with diabetes.
