Population aging is continuously increasing in Italy and in the World. Individuals aged 60 years or more are currently 10,500,000 and will be 13,000,000 in 2015. Life quality in geriatric ages includes the maintenance of sexual power: according to recent data (Carrol et al., 1992), 80% of impotence cases are due to organic causes. In addition, the use of drugs can cause impotence. Among them tiazidic diuretics may cause an increase of sexual disturbances. Other drugs with this potential are digitalis, antihypertensive drugs (particularly beta blockers), major and minor tranquillizers, antidepressant, H2 receptor antagonists, antiparkinsonian cholinergic drugs and estrogens employed in the treatment of prostate tumors. Diseases of geriatric age that can alter sexual power are diabetes mellitus, ischemic heart disease for the accompanying depression and for the use of antidepressants; severe hypertension is complicated by impotence in 15% of cases. Among neurological diseases Parkinson's disease and multiple sclerosis can be causes of sexual dysfunctions. Patients on hemodialysis can be impotent, with recent data (Soloh et al 1992) showing that erythropoietin treatment of anemia also improve sexual dysfunctions. Prevention from a geriatric standpoint should be base on action on known risk factor as smoking, alcohol abuse and dislipidemias and with the activation of a close drug vigilance.
