Premature ejaculation also belongs to one of the male sexual dysfunctions, and epidemiological surveys show that premature ejaculation is one of the most common male sexual dysfunctions. Data from a survey conducted by the Center for Health and Social Life in the United States showed that 21% of men aged 18 to 9 years in the United States had a prevalence of premature ejaculation, which shows that a very large number of men suffer from this disease. Other reports range from 5 to 30%, and this wide variation may be due to the different definitions of premature ejaculation in various studies. It is difficult to give an appropriate definition of premature ejaculation, and a widely accepted definition of premature ejaculation has yet to be established. The American Urological Association published guidelines on premature ejaculation in 2005, which define premature ejaculation as the ejaculation of the penis before or shortly after entry into the vagina, before the desire to ejaculate, resulting in a sense of loss for oneself, one’s partner or both partners, provided that sexual dysfunction of the partner is excluded. Premature ejaculation can be divided into primary and secondary premature ejaculation. Primary premature ejaculation refers to a situation in which premature ejaculation is experienced continuously from the first sexual experience. These patients often have some characteristics, including fear of failure, self-restraint of sexual impulses, role substitution (from participants to observers of sexual life), and reduced frequency of sexual behavior. . Patients in this category are generally older and often have combined erectile dysfunction or have difficulty achieving orgasm and will seek treatment earlier. To date, the true cause of premature ejaculation remains a difficult mystery, with a great deal of research and study, including from physiological, psychological, behavioral and even sociocultural backgrounds. There are some arguments that premature ejaculation is a problem on a purely psychological level, as men’s early sexual experiences (including masturbation) are often done under the tension of fear of being discovered, and a pattern of fast-action sexual behavior develops, which is difficult to change in later sexual behavior in marital relationships. Some scholars have found that premature ejaculation patients really have different performance in terms of nerve conduction and sex hormone levels than normal people, and they believe that premature ejaculation patients have a physiological response that is easily aroused and overly sensitive. Some scholars even believe that premature ejaculation represents an evolutionary behavioral pattern of the species. From an evolutionary point of view, males who are able to ejaculate within a shorter period of time have a higher chance of fertilizing females and reproducing offspring. In contrast, males that take longer to ejaculate and mate are more likely to be invaded or killed by other males or even other species during the mating process, so premature ejaculation may be the result of evolutionary selection. There are many treatments for premature ejaculation, and before treatment, it is important to discuss all treatment options with the patient, as well as the benefits and drawbacks of each treatment method. The success of the treatment should also be assessed by the satisfaction of the patient and the sexual partner. More importantly, since premature ejaculation is not a life-threatening condition, the safety of the treatment should be given first priority. I. Behavioral therapy: Behavioral therapy includes increasing the frequency of ejaculation, adopting a female on male sexual position, stop and start (stop and start) ejaculation, squeezetechnique, pelvic floor muscle contraction exercises, etc. The short-term success rate is 95%, but long-term follow-up results found that 75% of patients are still the same after 3 years of treatment as before treatment, therefore Behavioral therapy still only has long-term effects on a small percentage of premature ejaculation patients. Masters and Johnson proposed a male-under-female position, in which the man pauses when he feels he is about to ejaculate, and the woman lifts her body off the man’s, and even presses the glans three to four times below the glans. The woman can even press on the underside of the glans for three to four seconds to reduce arousal, and then continue after a break of 15 to 30 seconds. Other methods include distraction, change of position, etc. can also be used. In addition, the improvement of the relationship between husband and wife or sexual partners, emotional rapport, open communication, mutual understanding of the sexual sensitive areas of both sides, as much as possible some sexual foreplay and care after sex, can improve sexual life satisfaction, naturally can solve the tension and impact of premature ejaculation on the sexual life of both sides. The actual fact is that in addition to mental factors, physiological factors also often cause premature ejaculation. For patients with premature ejaculation, a comprehensive and detailed assessment of their physiological and psychological factors is necessary before appropriate treatment can be given. The drugs commonly used to treat premature ejaculation are divided into two categories: oral drugs and local topical drugs. 1, oral drugs are mainly selective pentazocine reuptake inhibitors (SSRI), these drugs were originally used to treat depression, but after long-term clinical application, it was found that there are several drugs that cause significant delayed ejaculation after taking, male specialists became interested in the side effects of this drug and soon used it for the treatment of premature ejaculation. The commonly used ones are Zoloft, Prozac, Sellett, etc. 2, local topical drugs are mainly local anesthetics. Local anesthetics (commonly used gels) are applied to the sensitive parts of the penis such as the glans, coronal sulcus and tether 20 to 30 minutes before sexual intercourse, which can prolong the ejaculation latency, and there are no obvious side effects. After applying local anesthetics, it is possible to use condoms or not. If a condom is not used, the residual drug can be washed off the penis before intercourse. It should be noted that excessively prolonged anesthesia (30 to 45 minutes) can lead to loss of erection because the prolonged anesthesia can make the penis feel numb in a significant number of people. If the residual medication on the penis is not thoroughly washed before intercourse (without the use of a condom), the spread of local anesthetic residues on the penis can also lead to numbness of the vaginal wall of the female partner and reduce sexual pleasure. If the patient or sexual partner is allergic to local anesthetic drugs, the treatment is contraindicated. Surgical treatment: If the above treatments are not effective, surgical treatment can also be considered. Commonly used surgical methods are selective dorsal penile nerve amputation and penile prosthesis implantation. As surgical treatment is somewhat invasive, doctors and patients should be cautious before choosing surgical treatment. Whether it is premature ejaculation or any other sexual dysfunction, it is challenging for both the patient and the male surgeon. Patients must unload their psychological baggage and discuss their hidden problems with their physicians, while physicians must listen carefully to the patient and perform the necessary tests to understand the real cause of premature ejaculation, whether it is organic or psychological, whether it is due to the patient’s own factors or to the social and cultural background, etc. If the cause of premature ejaculation is organic, the primary lesion should be actively treated and the problem can be solved. If it is functional, the factors that cause sexual tension should be excluded and the patient should be kept in a happy mood with correct sexual knowledge education and guidance, and both sides should cooperate and understand each other to achieve a harmonious interaction between the two sides in sexual life and normal life.
