Circumcision can be performed on babies who are circumcised at the age of two, but it is generally recommended to wait until the child is older. Circumcision generally means that in the natural state, the head of the male penis is only partially exposed or cannot be exposed. Symptoms of phimosis are generally characterized by the inability to turn up the foreskin or the head of the penis being completely covered by the foreskin, which, if left untreated, may cause phimosis and priapism. If a two-year-old baby is circumcised, circumcision is not recommended on the premise that the baby does not have frequent episodes of phimosis and so on. This is because circumcision for two-year-old babies usually requires anesthesia, which is less tolerated by younger children and can be risky. It is recommended that babies be circumcised during the summer and winter vacations when they are of school age, and it is advisable to consult a professional pediatric urologist for specific circumcision or not.
