Impotence occurs in approximately one third of Parkinson's disease (PD) patients. It results from autonomic insufficiency, and is accompanied by other signs of autonomic insufficiency. Impotence may be aggravated by antiparkinsonian drugs and depression. Conversely, impotence may aggravate depression. In some patients, tremor, seborrhea, and drooling aggravate impotence by resulting in loss of self-esteem. The causes and treatment of impotence in PD are discussed in this article.
