This question is often asked, now the relevant research is briefly summarized: 1, men at birth are physiological prepuce, with the growth of the penis glans and foreskin plate will slowly separate, before the age of 5 years old penis rarely developed, so little change, after slowly growing, after puberty, rapid growth, about 16 years old that is, circumcision is long, not long, prepuce, etc..
2, epidemiological surveys show that: You too people are born in January that circumcision, since the written records of the You too people have only 7 cases of penile cancer patients, female cervical cancer is also less, Islamic boys must also be circumcised before the age of 7, called “small marriage”, it is clear that the importance of the penis development is significantly better than “uncircumcised “The development of the penis is significantly better than that of Chinese boys who are not circumcised. The proportion of circumcised American boys is over 80%, and the incidence of penile cancer is 1000 times lower than that of less circumcised Japanese. It can be seen that the benefits of circumcision outweigh the disadvantages!
3, I think it is best to perform circumcision before puberty, one does not affect the development of the penis, the other can be operated under local anesthesia, low requirements for patients, less impact!
