It is unfortunate that long-standing diabetes in men, especially those with poor control of blood glucose, often leads to impotence (erectile dysfunction). By age 43, according to some studies, 46 percent of men with type 1 diabetes experience erectile dysfunction. Some women also report diminished sexual responsiveness, probably due to decreased sensation. Achieving and maintaining an erection is a complex action in which the circulatory, nervous and endocrine systems all play a role and interact with psychological and emotional factors. Diabetes can affect any or all of these systems. Autonomic neuropathies or vascular problems are the usual causes of sexual performance problems for men. Longer duration of diabetes, poorer control of blood glucose and the presence of other neuropathies all increase the likelihood of impotence. Psychological factors such as anxiety and depression can also cause or contribute to erectile dysfunction, which may be temporary or more long-lasting. The happy news is that a number of devices and medications can improve sexual function. Penile implants areone option. Some men with diabetes may get relief for their erectile dysfunction from the drug Viagra, which acts by preventing the blood needed for an erection from flowing out of the penis. Neuropathies, including those that cause impotence, can be prevented, first and foremost, with good blood glucose control. Smoking also contributes to neuropathies, so smokers should quit smoking. Maintaining normal blood pressure may also be protective. Beyond that, there is not much that can be done to prevent autonomic neuropathies. Last Updated: 6/25/2003
