Generally speaking, if the titanium nail does not fall off completely thirty days after circumcision, it is recommended to wait for another month, and if it does not fall off, it is recommended to go to the hospital to get the titanium nail. For people who have been circumcised for 30 days, if the titanium nails have not completely fallen off at this time, it is possible that the titanium nails have not yet fallen off, or the titanium nails have entered the tissues and other reasons. Generally, the titanium nail will start to fall off about 2 weeks after the operation, and it will fall off completely about 4 weeks after the operation, and sometimes it will be extended to about 2 months, but the exact time varies from person to person. Therefore, if the titanium nails have not completely fallen off 30 days after surgery, you should wait for another month. If the titanium nails have not completely fallen off about 2 months after the operation, it is necessary to go to the hospital for the removal of titanium nails, and it is not recommended to remove the titanium nails at home by yourself, in order to avoid bleeding and other undesirable consequences.
