First of all, it is recommended that men who think they have premature ejaculation should first go to a professional doctor to confirm whether it is really premature or not. Because premature ejaculation has its own proprietary clinical criteria, the definition of premature ejaculation is still controversial and is usually evaluated by the ejaculatory latency of men or the frequency of women reaching orgasm during sexual intercourse, for example, by the criterion that men lose the ability to control ejaculation during sexual intercourse, then ejaculation occurs before or just after penile insertion into the vagina; or by the criterion that women reach orgasm less than 50% of the time during sexual intercourse, but these are not universally accepted. The ejaculatory latency of men is affected by age, length of abstinence, physical condition, and emotional psychology, while the frequency of female orgasm is also affected by physical state, emotional changes, and the surrounding environment. In addition, there are individual differences in the length of ejaculation latency. It is generally considered normal for a healthy male to ejaculate after 2 to 6 minutes of penile penetration into the vagina. There are many psychological factors that cause premature ejaculation, such as the fear of failure of sexual intercourse and emotional anxiety that many people fall into premature ejaculation for various reasons; those who habitually masturbate when they are young, always aiming to achieve orgasm quickly; lack of sexual knowledge, only to meet the male purpose; couples are not good at tacit cooperation; emotional disharmony, aversion to spouse, intentional or unintentional sadistic consciousness; fear of sexual behavior is detrimental to health, exacerbating some inherent body Disease; too little frequency of sexual intercourse or a long time sexual repression; and the female partner aversion to sexual intercourse, worrying, forced to request a quick end to intercourse, etc.. All of these can lead to premature ejaculation and even a chain reaction, affecting erectile capacity. The genitourinary system diseases such as urethritis, prostatitis, vesiculitis and prostate enlargement are related to premature ejaculation. In terms of treatment, firstly, psychological treatment should be the main focus, which requires the collaboration of both spouses, especially the participation of the wife in the treatment is very important. The psychological treatment of premature ejaculation requires the cooperation of the patient’s wife. Because the misunderstanding or complaint of the female partner will make the male partner’s tension and anxiety rise and increase the psychological burden. The female partner should have a sympathetic and caring attitude, give words and behavioral comfort, relieve the male partner’s tension and help him establish confidence in the cure. Both husband and wife should be informed that premature ejaculation is a common problem, and both husband and wife need to know the necessity and possibility of rebuilding the ejaculatory reflex, eliminating the patient’s anxiety, anxiety, self-guilt and other abnormal psychology, building confidence in curing the disease, and that it can be cured as long as both parties cooperate with the treatment. The second is oral medication. The current treatment drugs, mainly including 5-hydroxytryptamine reuptake inhibitors, such as dapoxetine, taken orally 3 hours before sex, can generally play a role in prolonging the latency of ejaculation. Of course, it has certain side effects, and treatment should generally be considered after seeking medical attention first. Generally, 6 times a month is a course of treatment. The third is the use of local treatment, including local anesthetics. It can be applied near the coronal sulcus before sexual intercourse, along with the use of condoms, to a certain extent, can play a role in delaying the latency of ejaculation.
