Premature ejaculation is the most common ejaculatory dysfunction, with the incidence accounting for more than 1/3 of adult men. The definition of premature ejaculation is still controversial. It is usually evaluated by the ejaculatory latency of men or the frequency of women reaching orgasm during sexual intercourse, such as the standard that men lose the ability to control ejaculation during sexual intercourse and ejaculate before or just after penile insertion into the vagina; or the standard that women reach orgasm less than 50% of the time during sexual intercourse to define premature ejaculation, but these are not universally accepted. The ejaculatory latency of men is affected by age, length of abstinence, physical condition, emotional psychology and other factors, 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 ejaculatory latency. It is generally considered normal for a healthy male to ejaculate within 2 to 6 minutes of penile insertion into the vagina. Most patients try to prolong the ejaculation latency by turning their thoughts to other aspects during sexual intercourse, such as diet and play, or by using condoms and drinking alcohol, but the effect is not good, instead it often leads to a reduced libido and sexual pleasure disorder, and can even cause erectile dysfunction, thus aggravating the condition. So the treatment of premature ejaculation should be based on the cause of the onset, choose the appropriate treatment method. 1, psychological treatment requires the collaboration of both husband and wife. 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, and building confidence in curing the disease, which can be cured as long as both parties cooperate with the treatment. 2, behavior method guidance Sexual concentration training of the basic treatment method, the purpose is to teach patients to experience and enjoy the pleasure of sex through hugging, touching, massage and other tactile stimulation means to overcome psychological barriers. You can also pull down the scrotum and testicles before reaching orgasm, or use your thumb and finger to squeeze the glans to reduce sexual arousal and reduce erectile hardness by 10% to 25%. After a long period of training and then intercourse in the female superior position, still using the form of pumping – stop – pumping again repeated training, gradually improve the ejaculatory stimulation threshold, so as to achieve a more satisfactory artificial control before ejaculation. 3, oral drug therapy The current drug therapy is mainly 5-hydroxytryptamine reuptake inhibitors, domestic has been listed is dapoxetine hydrochloride, that is, the trade name of Bilevel. 30 mg, 3 hours before sex orally, it is mainly to extend the ejaculation latency, it has certain side effects, and indications, must be taken under the guidance of a doctor. It is more expensive. Other similar drugs such as Paroxetine should be applied under the guidance of a doctor. 4, local medication Mainly local anesthetics, can be applied to the head of the penis before sexual intercourse, through the role of local anesthesia to delay the latency of ejaculation. 5.Cavernous drug injection therapy This method of premature ejaculation still exists, but the erection of the penis can be maintained for a certain period of time after ejaculation, and it may be helpful to improve the sexual satisfaction of the spouse. 6.Transurethral drug delivery (MUSE) can also be used for the treatment of premature ejaculation. 7.Penile prosthesis implantation is suitable for patients with abnormal penile erection accompanied by premature ejaculation. 8.Penile dorsal nerve amputation This method is still in the trial stage in foreign countries.
