Normal aging does not induce impotence, but only modifies the physiology of the erection which, however, allows good sexual intercourse. Impotence, found in 55.0% of the over 75 men, is due to organic or psychogenic causes: above all, penile arterial insufficiency and the collateral effects of drugs for the diseases which often affect the elderly, are the main factors.
正常衰老不会导致阳痿，只会改变勃起的生理机能，不过仍能进行良好的性交。在75岁以上的男性中，55.0%存在阳痿问题，其原因是器质性或心理性的：首要的是，阴茎动脉供血不足以及常用于治疗老年人常见疾病的药物的副作用，是主要因素。
