Some foreign sexologists believe that 7-13 minutes (10 minutes on average) is the ideal length of lovemaking. American surveys have found that the average length of true lovemaking for partners is about 5 minutes. The average intravaginal ejaculation latency time (sex time) for men in China is 2-6 minutes. But such a short time does not seem to meet the man’s desire, but also to meet the feelings of women, so, in the material life of the great richness of the Chinese land happened a strange thing, the vast majority of men think they have premature ejaculation and suffering, only those who have delayed ejaculation, not ejaculation of men really know the pain caused by their long sex life, really “green trees The whole thing is staged in a “siege” war. For the human instinct, the current medical technology can not be contrary to the instinct, that is, there is no way to cure this premature ejaculation, equivalent to say that there is no way to make people live a long life. The actual myth is always there, in private hospitals, “penis decellularization dermal implantation surgery” has become the darling of some private hospitals, whether it is network publicity, office visits, will be recommended to you as the main product for the treatment of small penis, premature ejaculation, as if you do not do this surgery, you are sorry for their penis, sorry for such an advanced surgical design. It would be sorry for such an advanced surgical design. 1, because the original private hospitals rely on the killer app “dorsal nerve blocking penis” is widely known as a disease, by netizens – the hospital called “premature ejaculation nemesis” netizens called The actual “eunuch surgery”. The private men’s hospital has kept pace with the times, and the “penis decellularization dermal implantation” was packaged and then launched, and it can be said that the jungle is full of its legends. And it’s high cost and lucrative, naturally more tempting. 2, penis decellular dermis surgery, the purpose of the surgery is designed by implanting decellular biological patch on the surface of the penile corpus cavernosum, underneath the skin, covering the surface of the dorsal nerve of the penis and forming an isolation to reduce the stimulation of the dorsal nerve during sex, and can achieve the role of thickening the penis. I use an analogy: the glans is equivalent to a person’s head, while the penis body is equivalent to the human body, sexual life is equivalent to fighting, this surgery, equivalent to the human jacket (foreskin) underneath the person wearing a horse jacket, with a view to the horse jacket to make the body bloated, feeling sluggish, able to withstand longer blows without falling down. 3, but the designers ignored a major problem, that is, the main sensation of the penis comes from the glans, the sensation of the main part of the penis is not important in sexual life in the first place, so blocking the sensation of the dorsal nerve in the main part of the penis is basically useless for the treatment of premature ejaculation. To continue the analogy: in a fight, the body is protected, but the easiest to get injured and the easiest to make people fall is the head, and the head is not protected, so the results of horse clamps for fighting are predictable – basically ineffective. Hospitals, in order to change this passive situation, often do a dorsal penile nerve block on the patient at the same time as the surgery, that is, block the sensation of the head, with a view to achieving results. 4, the expert clinic, encountered several cases in private hospitals have done this kind of surgery patients to see, said the penis after surgery, the size of the change is not much, into a “dead penis”, through the observation found that this kind of penis does seem “bloated” and “old”, think carefully, decellularized dermal patch, equivalent to wearing a horse clip inside the original foreskin, because this layer of the horse clip does not have the foreskin of the kind of stretch, so it will bind the penis erection expansion, and penis weakness, and will support the foreskin can not follow the weakness, resulting in a relatively fixed size of “dead penis”. 5, the size of the male penis, as long as it is within the normal range, are able to meet the needs of women’s sex life. Normally women’s vagina has a depth of 7-12cm, a short front wall and a long back wall, a width that can accommodate two fingers, and a vaginal wall with many transverse wrinkled walls that have greater stretch and elasticity. The vaginal extension increases by one third during excitement, so there is usually no mismatch between the reproductive organs. According to the results of several large-scale surveys in China, the length of adult male penis in China is 4.5~8.6cm in normal non-erect state; the circumference is 7~9.5cm. 7~16cm when erect (the average normal range is 10.87~15.27cm) and the circumference is 9~12.5cm, which are normal. And it was found that there was no relationship between male height and length. It was also observed in the clinic that the penis with a larger appearance did not increase much in length during erection, while the penis with a smaller appearance increased more in length during full erection. It can be seen that any penis within the normal range can achieve the normal sexual function when erect state, no need to worry about the so-called “penis is too short”. The last point to emphasize is that more than 50% of premature ejaculation is related to psychological factors, so surgery alone cannot solve this part of premature ejaculation, while less than one third of premature ejaculation is caused by glans sensitivity, so it is not recommended to blindly perform this surgery. Selective excision of dorsal penile nerve According to scholars’ research, hypersensitivity of the dorsal penile nerve may be an important pathophysiological basis of primary premature ejaculation. Due to the increased sensitivity of the penis to vaginal wall friction during sexual intercourse, it leads to the acceleration of the accumulation of sexual stimulation value, which quickly reaches the ejaculation threshold and causes premature ejaculation. The principle of the surgical design is to cut off part of the branches of the dorsal nerve distributed to the glans to reduce the sensitivity of the glans, increase the tolerance of the glans to sexual stimulation and delay the time to reach the ejaculation threshold, so as to achieve the purpose of prolonging sexual life. However, the ideal is very rich, the reality is very skeletal, elevated sensitivity of the dorsal nerve of the penis exists only in some patients with premature ejaculation, clinical treatment found that the final efficiency of this operation is less than 50%, and the operation is an irreversible nerve cut, if the operation is not done properly resulting in complete severance of the main trunk of the dorsal nerve of the penis, it will cause numbness of the glans and even complete loss of sensation, bringing endless pain to the patient. The procedure is packaged as a means of enrichment by private male hospitals and carried out in large numbers, but their technical strength is weak, so the effect of the operation is worse, and is jokingly referred to by netizens – hospitals called “premature ejaculation nemesis” netizens called “eunuchs The surgery”.
