Circumcision for men is mainly related to circumcision, phimosis and other diseases. 1. Excessive foreskin: theoretically, simple circumcision does not need surgical treatment, but excessive foreskin will affect personal hygiene and easily cause recurrent infections, which can be considered for surgical treatment according to the individual’s wishes. 2. Phimosis: Phimosis is a narrow opening of the foreskin, which can not be turned up to reveal the head of the penis, and newborn baby boys present the state of phimosis, which belongs to the physiological phimosis, and can be left untreated for the time being, and most of the physiological phimosis will be cured with the age and growth and development of the baby. Most of the physiological circumcision will heal itself with age and growth. If the circumcision is pathologic, it needs to be treated by surgery. Circumcision is the removal of the excessively long foreskin, which is one of the more common surgeries in urology. It is recommended to choose a local public hospital for the surgery, as the doctor will have more clinical experience and can avoid accidents.
