Sex is an eternal topic in the life of couples, and a harmonious and satisfying sex life is a natural need for men and women’s physiology, but premature ejaculation has become one of the main reasons affecting the harmonious sex life of couples, which seriously affects the relationship between couples and may even lead to the breakup of the family. So, what is premature ejaculation? What is considered premature ejaculation? There is no complete agreement internationally, but the incidence of premature ejaculation accounts for 14% to 41% of adult men. Professor Wu Jieping, a famous urologist in China, believes that the latency period of ejaculation is 2 to 6 minutes for healthy men in their young and strong years, and as long as ejaculation occurs 2 minutes after the start of sexual intercourse, it is not considered premature ejaculation. Some scholars believe that we should focus on the quality of sexual intercourse, and that premature ejaculation is defined as a sexual satisfaction rate of less than 50% of the sexual partner during intercourse. There are many treatment methods for premature ejaculation, usually using sexual concentration training and oral antidepressant treatment, but due to the heavy side effects of taking medication, some patients are not effective at all, even if it is effective in the short term, most patients will rebound after stopping the medication, so it is difficult for patients to persist and the efficacy is not satisfactory. Since 2008, our hospital took the lead in introducing the distal dorsal penile nerve selective excision for premature ejaculation in the province, and improved on the basis of the introduction, taking the distal dorsal penile nerve selective excision combined with the penile tether sheep intestine implantation for premature ejaculation, the efficiency of sexual life after the operation is as high as 94%, relieving the pain for more than a thousand patients, and the technology has been identified by experts to enter the ranks of domestic advanced. At the same time, the operation has the following advantages: easy, small trauma, safe, short operation time; long maintenance time, does not affect sexual desire, basically does not affect erectile function; no need for sexual partners to participate, sexual partners feel good, easy to be received by both sides; after the operation, the ejaculation latency is extended significantly, sexual life satisfaction is improved significantly; after the operation, the penis appearance is beautiful, by the unanimous praise of patients. So, which patients are suitable for this surgical treatment? We believe that patients with normal erectile function, premature ejaculation since the first sexual intercourse; ejaculation latency less than 2 minutes; less than 20 penile intra-vaginal strokes; sexual satisfaction rate of sexual partners less than 50%; unable to control ejaculation after 2 months of ejaculation control training treatment; generally Q40 years old, or >40 years old but with strong desire for surgery; excluding psychological barriers; married or with regular sexual partners, with regular sexual intercourse. Those who meet the above conditions can be considered for treatment by distal dorsal penile nerve selective excision combined with penile tethered amniotic wire implantation.
