[Epidemiology and treatment of long-term male impotence].

Male impotence has assumed increasing clinical importance and the perfection of diagnostic and therapeutic methods has opened new horizons for medical treatment. The aim of this paper is to provide a review of the epidemiology of this disorder with the relative diagnostic and therapeutic correlations. The authors report a series of 161 patients who were treated for one year at most with prostaglandin E1 (Alprostadil alpha-cyclodextrin).
