With the rapid socio-economic development, people’s spiritual and cultural needs are growing and the concept of treating sex has changed. When people start to explore the problems related to sex life, the streets are flooded with advertisements specializing in impotence and premature ejaculation, and various male hospitals are springing up. The people were confused in the middle of these messages that screamed “cure for all kinds of male difficulties”. It is a good thing that these hospitals with their fabulous technology are not able to solve people’s problems at the root, they seem to be more interested in the money that the patients bring. In view of some of the doubts that people face, the following briefly gives you some general knowledge about male medicine, which I hope will help you. What is impotence? Impotence, because of its derogatory connotation, has now been replaced internationally with the term erectile dysfunction (ED). Erectile dysfunction is the persistent inability to obtain an erection, or to maintain an erection sufficient for satisfactory sexual intercourse on a consistent basis. Generally, ED is diagnosed when symptoms persist for 3 months. if a person does not achieve an adequate erection once in a while during sex, it is not ED; the condition may be related to environmental, psychological, and other factors. The actual fact that some people often suspect that they have ED when this happens, and that day and night thinking about it adds to the burden of thought, but causes more disharmony in sexual life. Although ED is a benign disease, but ED can affect psychosocial health, the quality of life of patients and their partners also has a significant impact. With the growing awareness of ED in recent years, it is now believed that the occurrence of ED is related to its cardiovascular system, endocrine system and poor lifestyle such as smoking and drinking. Therefore, when going to the hospital for ED, doctors will first rule out organic causes, such as cardiovascular disease, diabetes, hyperthyroidism, etc., because ED may be a symptom that accompanies these diseases. What is premature ejaculation? When talking about ED, it is inevitable that his relative “premature ejaculation” (PE) is involved. People often confuse impotence and premature ejaculation as if they are the same disease, but they are not. Premature ejaculation, as a male sexual dysfunction, has a unified definition consisting of the following three parts: 1. Primary premature ejaculation: repeated ejaculation in about 1 minute after contact with the vagina from the first sexual intercourse, or continuous ejaculation; 2. Secondary premature ejaculation: ejaculation latency time drops to 3 minutes or less after contact with the vagina from the first sexual intercourse. 3. delayed ejaculation disorder occurs in all or almost all vaginal penetrations. 4. Negative personal effects such as apprehension, worry, confusion, and/or avoidance of sexual intimacy occur. Common misconceptions about premature ejaculation We should pay attention to the third part in addition to the difference between primary and secondary premature ejaculation. For example, if the male partner ejaculates for less than 3 minutes but the female partner is satisfied with her sex life, this should not be diagnosed as premature ejaculation. Many times clinicians ignore the emotional changes that premature ejaculation brings to the patient and focus only on whether the treatment measures taken can prolong sexual life; at the same time, some people seek to prolong sexual life at the expense of the people and regret it in the end. In this treatment guideline, we should note: selective dorsal penile nerve excision or the use of hyaluronic acid to enlarge the glans may lead to permanent loss of sexual function and is not recommended for premature ejaculation treatment. Therefore, dorsal penile nerve block currently performed in major XX male specialty medical institutions is not recommended for the treatment of premature ejaculation under routine. The actual fact is that you should understand how to distinguish ED from premature ejaculation. The last word: If you suspect that you are suffering from sexual dysfunction, you should choose a regular hospital and be cautious about the advertisements that cure all diseases.
