[Primary and secondary prevention of erectile dysfunction].

Erectile dysfunction has an incidence of up to 75% in men aged 80, thus making primary prevention really important. Aetiologically multiple reasons are responsible for erectile dysfunction; therefore, recommendations for primary prevention contain different parts. The first one is to maintain a healthy arterial system and prevent atherosclerosis. Besides that diabetes, neurogenic disturbances or mental distress should be avoided. Physical activity, balanced nutrition, nonsmoking, unsaturated fatty acids and moderate alcohol consumption are preventive. Regular erections cause oxygenation of the cavernous body and prevent fibrosis which could lead to an insufficient occlusion of the cavernous veins. If the patient already suffers from coronary heart disease or diabetes, blood pressure, pulse, blood lipids and blood sugar should be as normal as possible. Erectile dysfunction might be the primary symptom of coronary heart disease; therefore, consideration should be given to a cardiac examination in the diagnostic setting.
