A. Introduction to circumcision: The prepuce and prepuce are common in most male children, and many parents do not pay enough attention to it after the birth of the child, and do not regularly perform the foreskin flap to reveal the glans and clean the prepuce, and only when there is a foreskin infection or difficulty in urination do they seek medical attention, which is not conducive to the genital development of male children. Individuals even have severe circumcision that restricts the development of the glans, resulting in small genitalia, and only after marriage do they taste the bitter consequences, but it is too late and they regret it for life. In the United States, for example, more than 90 percent of newborn boys are circumcised shortly after birth. With the development of society and the improvement of people’s own culture and knowledge, more and more attention is now being paid to the sexual organs of male children and to sex education, so there are now more and more circumcised male children. The best time for children to be circumcised is? According to the opinions of most experts in the country and my personal experience of performing circumcision in more than 7000 cases, 5-7 years old is the best period. The reasons for this are: 1. Children can withstand local anesthesia during this period, and the risk of accidents caused by anesthesia is small. 2, the child’s own wound healing and repair ability is strong during this period, and the post-operative scar is small. 3. Early exposure of the glans is conducive to stimulating penile growth and development. The surgical experience during this period is conducive to the exercise of the boy’s brave character and temperament.
