Mr. Li is very miserable because when having sex with his girlfriend, it is difficult to control his urge to ejaculate, after inserting his girlfriend’s vagina and ejaculating after a few thrusts, his girlfriend is very dissatisfied with this. This kind of thing is too embarrassing to tell to others, so it is very bitter to keep it in your heart. This is why he came to our reproductive male clinic for help. The problem that Mr. Li has is actually premature ejaculation. Premature ejaculation refers to a man’s poor ability to control ejaculation during intra-vaginal intercourse, before or shortly after penile insertion into the vagina, and before he wishes to ejaculate, causing dissatisfaction and distress to himself or his sexual partner. Premature ejaculation is the most common sexual dysfunction disease, with an average prevalence of 20% to 30% in men. Young men are especially prone to premature ejaculation due to their lack of sexual experience. Premature ejaculation can seriously affect the relationship between men and their female partners, leading to mental distress, low self-esteem, anxiety and depression and other adverse emotions and psychological disorders, causing a decrease in libido and avoidance of sexual activity, and can even lead to a breakdown in the relationship between men and women. Since premature ejaculation is so harmful, how to treat it? Sexual intercourse behavior training, essential before treating premature ejaculation, the first thing to understand is what the nature of premature ejaculation is. Premature ejaculation is actually a behavioral habit of ejaculation, which is fundamentally different from organic diseases such as pneumonia and fractures. Behavioral habits need behavioral training to correct them, so behavioral training for sexual intercourse is essential for the treatment of premature ejaculation. Patients with premature ejaculation need to undergo behavioral training for sexual intercourse under the guidance of a professional male physician. When having intravaginal intercourse, use sexual techniques such as the dynamic D-stop combination technique to suppress the urge to ejaculate and improve control over the timing of ejaculation. Patients with premature ejaculation must gradually become proficient in using sexual techniques to control their ejaculatory impulses and prolong the duration of intravaginal intercourse through multiple sexual intercourse behavioral training, and then form a habit in order to cure premature ejaculation at its root. It is clear that the cooperation of the female partner is also important for the treatment of premature ejaculation. The man who has premature ejaculation must be treated in time, do not wait until the divorce or breakup, and then go to the hospital to treat premature ejaculation, thus missing the opportunity to treat. The actual fact is that you can find a lot of people who are not able to get a lot of money from the internet. Some patients with severe premature ejaculation may not even be able to use their sexual skills before they ejaculate, or their female partner may break up before they have completed enough training sessions. Therefore, medication is very important for the treatment of premature ejaculation, but it must be used under the guidance of a professional male physician. Selective 5-hydroxytryptamine reuptake inhibitors (SSRIs), are the drugs of choice for the treatment of premature ejaculation. It has been found that 5-hydroxytryptamine is a neurotransmitter involved in the control of ejaculation and that inhibition of 5-hydroxytryptamine reuptake delays the ejaculatory impulse in men. Dapoxetine is the only SSRI approved for the treatment of premature ejaculation. It has a rapid onset of action, can be cleared rapidly in the body, and has few side effects. Oral dapoxetine taken 1 to 3 hours before sexual intercourse, together with intercourse behavior training, has good efficacy for all kinds of premature ejaculation. Local anesthetic drugs, such as lidocaine cream, applied to the surface of the penis head before sexual intercourse can reduce penile sensitivity and weaken the ejaculatory impulse. However, it tends to cause numbness of the penile head and lack of sexual pleasure, and long-term use may lead to decreased or lost erectile function, and is only suitable for short-term use for a portion of premature ejaculation patients. For surgical treatment of premature ejaculation, selective dorsal penile neurectomy is not recommended. Due to the lack of evidence-based medical evidence of its effectiveness in a large sample and its tendency to cause hyperalgesia, pain, and decreased or even lost erectile function, the risks far outweigh the benefits, and both domestic and international guidelines for the treatment of premature ejaculation do not recommend its use. More seriously, it is difficult to regenerate the nerve after it is severed. It is easy to sever the nerve, and almost impossible to restore full function to the severed nerve. Premature ejaculation patients must realize that penile sensitivity is not the main cause of premature ejaculation; the main cause of premature ejaculation is poor ejaculation control. Moreover, penile sensation is very important for male sexual function, being the main source of sexual pleasure and an important driving force for maintaining penile erection. Therefore, selective dorsal penile neurectomy should not be done easily.
