A month after the circumcision line is not off may be a normal phenomenon, may also be caused by wound infection. 1. Normal phenomenon: If the patient is circumcised with non-absorbable threads, it is considered normal that the threads have not fallen off more than a month after circumcision, and the patient needs to go to the hospital to have the threads removed. If the patient is circumcised using absorbable threads, absorbable threads will fall off by themselves in one to two months, so there is no need to worry about the threads not falling off more than a month after circumcision. 2. Wound infection: If absorbable thread is used during circumcision, and the patient’s wound is infected after the operation, it will affect the absorption and shedding of absorbable thread, which will also make the patient’s thread not fall off more than a month after circumcision. It is recommended that more than a month after circumcision wound sutures did not fall off need to consult a doctor in time, if it is a normal phenomenon can not be treated. If the wound is infected, you need to disinfect the wound with povidone-iodine under the guidance of a doctor, and then follow the doctor’s instructions with antibiotics.
