Summaries for Impotence

MedlinePlus: 41 Erectile dysfunction (ED) is a common type of male sexual dysfunction. It is when a man has trouble getting or keeping an erection. ED becomes more common as you get older.

It may mean your blood vessels are clogged. It may mean you have nerve damage from diabetes. If you don't see your doctor, these problems will go untreated. Your doctor can offer several new treatments for ED. For many men, the answer is as simple as taking a pill. Getting more exercise, losing weight, or stopping smoking may also help. NIH: National Institute of Diabetes and Digestive and Kidney Diseases

MalaCards based summary: Impotence, also known as erectile dysfunction, is related to vasculogenic impotence and prolactinoma, and has symptoms including tremor, angina pectoris and equilibration disorder. An important gene associated with Impotence is PDE5A (Phosphodiesterase 5A), and among its related pathways/superpathways are Signal Transduction and MIF Mediated Glucocorticoid Regulation. The drugs Nebivolol and Selegiline have been mentioned in the context of this disorder. Affiliated tissues include bone marrow, prostate and spinal cord, and related phenotypes are homeostasis/metabolism and normal

Disease Ontology: 11 A sexual dysfunction that is characterized by persistent or recurrent inability to achieve or to maintain an erection during sexual activity.
