[Morphofunctional changes of external male genitalia in alcoholism and substance abuse].

The external male genitals (EMG) of male corpses, who abused alcohol and narcotics at lifetime, were examined. The objects were stained according to the common histological and histochemical methods. The study results are indicative of a high frequency rate of pathologic changes of the EMG in persons, who abused alcohol and narcotics at lifetime. The inflammatory, fibrosing and atrophic changes of the EMG as well as a reduced vascular permeability can be a cause for erection malfunction.
