Erectile dysfunction (ED) is a common male disease. It refers to the process that the penis cannot erect for sexual life, or the erection is not firm, or the erection cannot maintain the completion of sexual life. It is one of the most common male sexual dysfunction in clinic. The mechanism of erectile dysfunction is a complete hemodynamic process including relaxation of the smooth muscle of the cavernous body of the penis, dilation of the penis artery, increase of blood flow and obstruction of venous return.
Male sexual function is a complex physiological process, involving various aspects, such as neural factors, mental factors, endocrine functions, sexual organs, etc., in which the sexual conditioning of the cerebral cortex plays a particularly important leading role. In clinical practice, ED is generally divided into functional, organic, neurological, endocrine, iatrogenic, pituitary, vascular and psychiatric diseases according to different causes. In clinical practice, most patients have several causes at the same time. Therefore, it can be divided into functional erectile dysfunction and organic erectile dysfunction. The former accounts for the majority of erectile dysfunction, while the latter is quite rare.
From the perspective of etiology, functional impotence is often closely related to mental factors, such as fear, depression, anxiety, and mental trauma; Because functional impotence and organic impotence are different in pathogenic factors, incidence, erectile function and prognosis, the treatment methods are also different. Therefore, functional impotence and organic impotence must be distinguished.
From the perspective of disease onset, functional impotence usually starts suddenly, while organic impotence usually starts gradually and progresses slowly and gradually. From the perspective of etiology, functional impotence is often closely related to mental factors, such as fear, depression, anxiety, mental trauma, guilt, marital discord, etc., without organic damage of genital organs. Organic impotence is often caused by anatomical defects of sexual organs, such as dysplasia Spina bifida, penis trauma, induration, systemic slowness, etc., but not related to spirit.
