In fact, even though people with diabetes are at a higher risk for sexual problems, a 2010 study in the journal found that only about half of all men with diabetes and 19 percent of women with diabetes have broached the topic with a doctor.
And, truth is, many doctors don't feel comfortable prodding patients for details on sexual function.
"Sexual desire is a brain-driven event," says Stacy Tessler Lindau, MD, MAPP, director of the Program in Integrative Sexual Medicine at the University of Chicago.
"If inflammatory molecules cross the blood-brain barrier and circulate in the area where there is sexual desire, then it's plausible the desire for sex may be affected." Another possible culprit: low testosterone, which often affects men and women with diabetes.
Studies have shown that men with diabetes, especially those who have type 2 or are overweight, or both, have about twice the risk of low testosterone as their peers without the disease, which can affect a man's passion for sex.
