“Doctor, I have back pain and weakness in my legs, I can’t have sex with my wife, what should I do?” “Director, help me, I am impotent, last week I had a room with my girlfriend, after ejaculation, she asked for another time, but was unable to get an erection, my girlfriend said I was ‘impotent’, I am so scared, I have not been able to get an erection this week! …… Phenomena like this are often seen in our male or sexual medicine specialty clinics, and these are mostly penile erectile dysfunction (ED), or “impotence”. Most of them occur in some middle-aged and elderly people, and those who actively request correction or improvement are mostly people who have high requirements for quality of life, including the quality of married life, some of whom are forced by their wives to come to the hospital, and some young people, including many college students, have ED. So, what exactly is erectile dysfunction? Erectile dysfunction (ED) is the persistent or recurrent inability of a man to achieve or maintain sufficient penile hardness for satisfactory sexual intercourse. (Unless ED is the result of trauma or surgery, the history of ED is at least 3 months.) Erectile dysfunction is one of the five components of male sexual dysfunction (including arousal, erection, vaginal penetration, orgasm-ejaculation, and sexual satisfaction), and ED is usually divided into organic ED, psychological (psychogenic) ED, and mixed ED (ED caused by a combination of non-organic and organic factors), with mixed ED being the most common clinically. Is the occurrence of ED scary? Many people are very nervous, because, whether the penis can be erect as expected for the ability to reflect the strong symbolic significance of men, and is directly related to the life of the couple and the relationship is an important event, of course, also affected by a variety of factors, including physical, psychological and social aspects of the combined effect. Therefore, once you find yourself unable to achieve or maintain sufficient hardness of the penis for a satisfactory sex life, you should promptly go to the general hospital’s male department or sexual medicine department to seek medical attention, find the cause, find the symptoms, and strive for early recovery. In fact, the occurrence of ED is not necessarily the body itself physiological lesions, many people, such as long-term tension, stress, depression, anxiety and bad mental and psychological factors such as marital discord caused by the inhibition of the brain center caused by ED. In addition, due to physical weakness, or long-term mental labor leading to neurological weakness, so that the parasympathetic nerve function is reduced, in general stimulation, the penile artery blood vessels can not expand as usual; or sexual life Excessive sexual life, the nervous system is in a high state of excitement for a long time, and eventually, due to excessive excitement and exhaustion, the spinal erectile center excitability is reduced and causes this disease. In addition, there are also some caused by the longer period of non-close cooperation of the female partner because of loss of pleasure. The previous notion was that erectile dysfunction was mainly caused by psychological factors, but later it was found that patients with erectile dysfunction often had some organic lesions. Nowadays, scholars believe that the majority of erectile dysfunction occurs due to both organic lesions and psychological disorders. The current data shows that the proportion of psychological ED, organic ED, and mixed ED each accounts for about one-third. To the hospital, the professional staff will understand in detail the causes and consequences of your onset, work status, family or interpersonal relationships and other relevant factors to understand whether you are psychological problems, so as to get a first impression, if the consideration is purely psychological problems, only need to do some guidance, guidance and advice, such as suspected psycho-psychological ED should be made psychological assessment. If there is a suspicion of organic disease, we should do some relevant tests, etc., to clarify whether the body itself has a problem and the type of problem, so as to establish the correct treatment ideas. Such as routine blood, urine, prostate fluid routine, blood electrolytes, blood lipids, blood sugar, liver and kidney function, thyroid function, etc., the determination of serum sex hormone six, etc., to clarify the lesion links on the hypothalamic-pituitary-gonadal axis. There are also some special examination means, such as nocturnal penile distension test (NPT), penile brachial blood pressure index (PBI), intracavernosal injection of active drug test (ICI), color bifunctional ultrasound examination of penile hemogram (CDU), cavernous biopsy, etc. Those with organic erectile dysfunction often have symptoms of other diseases, such as hypertension, diabetes, cardiovascular disease, and a history of surgery or trauma. The International Index of Erectile Function (IIEF) or the simplified scale (IIEF-5) is used to assess ED, which has become the most useful quantitative index for ED diagnosis and evaluation of outcome. In Chinese medicine, this disease is called “impotence”, “tendon impotence”, “non-use of the Yin apparatus”, and “not getting up”. Chinese medicine’s understanding of the disease first appeared in the Mawangdui medical book “the world’s most Taoist talk”, “and the violent use of the stroke, not waiting for its strong, can not tolerate two heat, is therefore the Excel injury”. Chinese medicine believes that the occurrence of ED involves the kidney, heart, liver and spleen, but the kidney is the main, the disease is mostly cold and deficient, the treatment of the kidney is the main, while the liver and kidney as the center of treatment from multiple organs. The ED of old and frail patients are mostly kidney deficiency, while young people are mostly liver Qi discomfort. Impotence pathogenesis to liver and kidney deficiency as a characteristic, treatment should be kidney tonification liver, but we should pay attention to the kidney tonification to take into account the liver, liver to take into account the protection of the kidney, in order to achieve better results. Other treatment methods include: the umbilical cord method, medicine bag method, anal drug delivery method, etc. Western medicine selects oral drugs such as hormone therapy and non-hormone therapy (such as cialis, vasodilators, etc.), physical therapy, drug delivery through the penile skin route, penile prosthesis implantation in severe cases, vascular surgery, etc. according to the condition. Clinically, the combination of Chinese and Western medicine can achieve good results by complementing each other’s strengths and weaknesses. Generally, most of the non-organic erectile dysfunction can be cured through psychological guidance and appropriate treatment, but the length of the disease varies. Mild organic erectile dysfunction can also be achieved to varying degrees through oral or local medication. Therefore, the occurrence of ED is not terrible, the key is to get timely and accurate guidance and help from professionals, many patients in good control of hypertension, diabetes, etc., after taking medication can achieve the desired erectile capacity. In terms of prevention, it is more important to strengthen sex education, understand general knowledge of sex, cultivate correct sexual awareness, abstain from masturbation, eat in moderation, and have sex in moderation. Husband and wife should respect each other, trust each other, exchange feelings with each other, the wife should be gentle, considerate and active to her husband, to create a relaxed, harmonious and pleasant atmosphere for sexual life. After the disease, the wife should understand, comfort, encourage the husband, and actively cooperate with the husband’s treatment, do not cold words, cold tide hot irony, which will only be counterproductive. Actively treat other diseases that cause erectile dysfunction. The diet of erectile dysfunction patients should be light, nutritious, high protein-containing food. In addition to this, to maintain a relaxed mood, the two bowel movements, is also to do a good job in the prevention of the necessary conditions of care.
