Erectile dysfunction is age-appropriate. So at a young age is dominated by psychogenic and functional mechanisms of erectile dysfunction syndrome (compulsive expectations of failure, violation of the regulation of erection due to vascular dystonia), as well as the true venous insufficiency of the penis. In the older age of these reasons almost no one has to consider.
For erectile dysfunction in middle-aged men are more pressing challenges in a violation of the regulation of erection due to diabetes mellitus, metabolic disorders, alcohol and nicotine, contact with radiation, spinal diseases, endothelial dysfunction.
To existing problems in men older than 45 years joined circulatory disorders in atherosclerosis, hypertension, snoring, obesity. Accumulating and summed pathogenic factors lead to an irreversible process - the formation of cavernous fibrosis, most often in the early stages of exerting themselves pathological venous leakage - withhold an erection.
We consider any erectile dysfunction is not as a fait accompli, and as the stage of disease. In the early stages are formed predominantly psychogenic mechanisms, gradually shifting in the direction of functional disorders of regulation of erection. The process ends with persistent organic anatomical changes. This is a typical course. However, there are forms of erectile dysfunction of primarily organic. For example, cavernous fibrosis due to injury of the penis (including chronic), arterial insufficiency of the penis (also traumatic nature), venous outflow due to the presence of a pathological extension of the vessel, Peyronie's disease and some others.
