In recent years, with the improvement of living standards and the updating of concepts, the public’s demand for sexual life has also increased. However, due to a variety of reasons such as the accelerated pace of social life, increased social pressure on men, drug abuse, and the accelerated aging of the population, erectile dysfunction has gradually become the main cause of low sexual function in men and disharmony in the sexual life of couples. Erectile dysfunction is commonly known as impotence in China and sexual impotence in the West, but the latter two are both with a certain pejorative meaning, so they are not advocated to use. Data show that the divorce rate of Chinese couples has continued to grow in recent years, and, purely physical disharmony and break up the case is soaring! No wonder all men talk about “impotence” color change! Due to stereotypes, sexual confusion shy to speak; lack of sexual knowledge and the lack of formal access to information, false advertising and a variety of “partial” “secret formula” instead of the popularity. Misunderstanding in turn affects the patient’s judgment and treatment of the disease, so that patients can not be timely diagnosis or into a “tonic kidney”, “aphrodisiac” of the misunderstanding, delayed the condition and aggravate the economic burden, the more serious is that once the treatment is ineffective may lead to or damage the The more serious is that once the treatment is ineffective, it may lead to or damage to the body or more lack of confidence in sexual life, so that the erectile function further deterioration. Erectile dysfunction refers to the persistent (at least 6 months) inability of the penis to achieve and maintain a full erection to obtain a satisfactory sex life; it refers to the inability of the penis to get an erection or erection in the presence of sexual stimulation and sexual desire, erection time is short, and soon flaccid, so that it can not be carried out with the completion of sexual life. Many patients who come to the clinic for treatment actually do not have erectile dysfunction, they tend to usually erectile response is not obvious for impotence, and even think that masturbation and frequent spermatorrhea will inevitably lead to impotence, in fact, the transition of masturbation may lead to the occurrence of ED, but it is not masturbation itself caused by the long term masturbation incurred mental and psychological factors that impede the normal performance of sexual function. In addition to the understanding of ED also need to make a few points of clarification: First, the sexual stimulus must be from the spouse of the adequate sexual stimulation; Second, should be able to really complete sexual intercourse to judge, generally believe that the frequency of its occurrence should be more than 50% of the sexual act; Third, must be after marriage between the couple of at least 2 to 3 months of bonding, with the practical experience of sexual life and then make an assessment; Fourth, any extramarital sex will be judgment of the bias. Fifth, it cannot be fully explained as a transient cause such as physical discomfort, momentary mood tension or exertion. If these principles are deviated from, it is easy to have a misjudgment of oneself and put the cap of impotence on oneself, and henceforth put on a mental shackle and fall down. It has been reported that almost 2/3 of men over 50 years of age suffer from varying degrees of ED. A study in Shanghai, China, from 1993 to 1994 showed that the incidence of ED among people over 40 years old was 73.1%, and rose to 86.3% at the age of 70. It can be seen that the incidence of ED is quite high, so what are the causes of ED in the end? Normal erection requires the close cooperation of neurological, endocrine, cavernous body and psychological factors. Any factor that affects one or more of the above four aspects may lead to the occurrence of ED, such as age, psychological factors, endocrine diseases, cardiovascular diseases, bad habits (e.g., smoking, alcohol abuse, unclean sex and drug abuse, etc.), and medications affecting the sexual function. The diagnosis of ED is easier through history taking and relevant tests such as hormone and penile cavernography. The treatment of ED is mainly based on medication and surgery. Medication is more commonly used than oral sildenafil, which accounts for 95% of the ED treatment market. Sildenafil, known as “Viagra” or “Wan Ai Ke” in China, is a highly selective phosphodiesterase V inhibitor, and is currently the first-line drug for ED treatment, and its safety and efficacy have been confirmed. However, it needs to work only after sexual stimulation, and must be taken before each sexual intercourse, which is very inconvenient and expensive. For patients who have failed conservative treatment or who wish to be relieved of their problems permanently, penile prosthesis implantation is the best choice. Currently, the most common penile prosthesis implantation is a three-piece procedure. The so-called three-piece kit consists of two cylindrical rods, a hydraulic pump, and a reservoir capsule. The two cylindrical rods are surgically implanted into the corpus cavernosum of each side of the penis, the hydraulic pump is placed in the scrotum and the reservoir is placed in the pelvis behind the pubic symphysis. Before sex, the pump is squeezed and water flows from the sacs into the rods, causing the penis to thicken and harden, while at the end of sex, the pump is squeezed and water flows from the rods into the sacs, causing the penis to weaken. As this kind of surgery can completely improve the erectile function, without the limitation of time and drugs, it has been rapidly carried out at home and abroad, and the efficacy is certain. Moreover, the domestic also has its own production of three-piece manufacturers and stable performance, which greatly reduces the cost of surgery and materials, Tongji Hospital has done more than a dozen such surgery, after follow-up, almost all patients are satisfied with the postoperative erectile function and sexual life of couples.
