Erectile dysfunction is commonly known as “impotence” in China and “sexual impotence” in Western countries, but considering that both names have a certain derogatory meaning and neither of them can describe the essence of the disease, it is very necessary to give a more appropriate name. In 1993, the medical community began to adopt the name “erectile dysfunction (ED)”, which is now widely adopted by the academic community because it can fundamentally explain the essence of the disease and is more easily accepted by both doctors and patients psychologically, and is therefore It is now widely adopted by the academic community and known to the general public. Erectile dysfunction is defined as the persistent inability of the penis to achieve or maintain an erection sufficient for a satisfactory sexual life. In other words, if the penis is often not sufficiently hard, or can be inserted but soon soft (can not maintain a full erection), one of the two is ED, and we should pay special attention to the word “often”, which usually takes 6 months. If this happens occasionally, or for a very short period of time, do not just diagnose ED. Obviously, according to this definition, ED involves people who have had sex. However, in men’s clinics, we sometimes encounter patients who are not sexually active but are suspected of having poor erectile function. In this case, the concept of “non-sexual ED” is proposed: no sexual intercourse for more than 6 months and the erection hardness and duration of the penis decreases, and the lack of confidence in erection makes it impossible to try to have sex. Of course, this concept has yet to be recognized by domestic and foreign scholars. It is generally accepted that erectile failure can occur in the lifetime of any man. Although there is no exact information on the incidence of ED, it is an accepted fact that the incidence of ED is high. Erectile dysfunction does not endanger the life of the patient, but it can greatly affect the patient’s quality of life, affect the patient’s self-confidence, and even endanger the stability of the patient’s family in serious cases. With the development of the economy and the renewal of concepts, people put forward higher requirements for sexual health, the World Health Organization’s definition of modern health to further this requirement to a theoretical level, that is, human health is not only the absence of physical disease, but should be a perfect state that includes physical, mental and social life. It should be noted that, due to the general lack of knowledge among our population, some patients treat one or two erectile failures as ED, and produce very obvious psychological barriers; while some patients see very serious erectile dysfunction as an inevitable natural phenomenon of aging and do not pay attention to; some patients think that ED can not be cured or lifelong need to rely on drugs. This is a misunderstanding of ED, need to be decisively abandoned. In fact, after suffering from erectile dysfunction do not need to panic, to go to the hospital in a timely manner. Both husband and wife should understand each other, treat correctly, and introduce to the doctor in detail the whole process of the development and change of the disease, while actively cooperate with the doctor’s treatment and active treatment of primary diseases that may cause erectile dysfunction, so as to facilitate the early recovery of the disease.
