Erectile dysfunction is a condition in which the penis persistently fails to erect or maintain an erection, making it impossible to have a satisfactory sexual life. This disease is commonly known as “impotence”, but many scholars believe that “impotence” is somewhat discriminatory and that it is more accurate to use the term “erectile dysfunction” (abbreviation ” ED”) is more accurate. It should be noted here that occasional erectile failure should not be classified as ED due to emotional and physical factors. ED etiology is traditionally divided into two categories: psychological and organic. The so-called psychological refers to ED caused by mental factors such as stress or depression; organic refers to ED caused by neurological, endocrine, vascular and cavernous smooth muscle lesions related to penile erection. because the disease seriously affects the patient’s psychological state, it is difficult to distinguish clearly in most cases. It is generally believed that those who wake up at night or wake up in the morning with a hard and long-lasting erection and cannot have an erection during sex are mostly psychological, but the correct diagnosis can only be determined after a series of tests by a specialist physician. In the past, it was believed that 90% of ED was caused by psychological factors, and this misconception led to thousands of patients condemning themselves, which only resulted in further aggravation of the condition. Current research shows that about 60% of ED is organic, or 80% of ED patients have some kind of organic factor. The following is an incorrect understanding of ED, should be corrected: 1, the appearance of ED is a sign of physical aging. This is a misconception. At present, the medical profession has formed a consensus that the appearance of ED is mostly associated with other diseases latent in the body. The information shows that about 100 million men worldwide suffer from ED, but 90% of them do not go to the hospital, because they believe that as the body ages, it will inevitably lead to ED. But recent studies have found that about half of the patients in ED are caused by other diseases. The reason for the higher incidence in the elderly is that those diseases associated with old age, such as diabetes, hypertension and the drugs taken to treat these conditions, are important factors that lead to ED. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. In short, for ED, first of all, to establish the correct concept, that is, ED is not only closely related to psychological factors, and with the development of medicine, has found that more and more organic factors are the culprit of ED. Therefore, suffering from ED, do not be timid, do not blame yourself, and do not be discouraged, should be treated like any other disease, timely to the hospital to receive appropriate treatment.
