How long is it premature ejaculation?
The evaluation of premature ejaculation currently uses the time of ejaculation incubation (that is, the time when the penis is inserted into the vagina to ejaculation) to evaluate. The epidemiological survey in Europe and the United States shows that the normal ejaculation incubation period is 2-8 minutes, and the ejaculation period of our survey of the Chinese people is 3-10 minutes.The reason why there is such a difference is because Europe and the United States uses a stopwatch time, and our data is based on the estimation of the interviewees.
The occurrence of premature ejaculation is greatly affected by the environment, experience, psychology, and husband and wife relationship.Its pathogenesis mainly includes high sensitivity of ejaculation center, high intimidation of peripheral nerve, and excessive sensitivity of penile skin sensitivity.According to its commonly used treatment, SSRIS (antidepressants) that reduce central nervous nervous sensitivity, reducing sympathetic nervous sensitivity & alpha; receptor preparations and local anesthesia to reduce the sensory sensation of the skin.Because premature ejaculation has a strong correlation with the patient's psychological characteristics, the most clinically used SSRIS that reduces central sensitivity. The overall effective rate of such drugs to patients with premature ejaculation is 70%-80%.
