[Erectile dysfunction. An important manifestation of autonomic diabetic neuropathy].
In Germany, some 4-6 million men, including 1.2 million diabetics, suffer from erectile dysfunction (ED). Various other diseases including heart disease, hypertension, arteriosclerosis, hyperlipidemia, endocrine disorders, chronic renal insufficiency, prior radical prostatectomy, neurological diseases, trauma and the abuse of alcohol, tobacco, and side effects of medications, are frequently associated with ED. Medical history, clinical examination, routine blood chemistry and sexual hormone levels may help clarify the etiology of ED. Normally, relaxation of the smooth muscles of the corpus cavernosum--mediated by cGMP and cAMP--together with dilatation of penile arteries and occlusion of venous outflow, results in an erection. The oral type V phosphodiesterase inhibitor, Sildenafil, or prostaglandin E1 injection elevates the cGMP and cAMP levels, respectively. Other therapeutic options include mechanical aids, surgery, hormone replacement or sublingual apomorphine. Since 1998, Sildenafil, an effective, simple and safe oral treatment, has been available.
