After circumcision, due to the presence of the incision, when the incision is not completely healed, if the penis is erected prematurely it can cause pain after erection and may cause an increase in foreskin edema. In this case, the patient should control the penis as much as possible after surgery and not allow it to become erect. In addition, oral medications can be taken to inhibit the erection of the penis, such as the oral medication Valium or vinpocetine estradiol during sleep. This can effectively inhibit the erection of the penis, thus avoiding symptoms such as incision cracking and pain caused by the erection of the penis. The incision can heal in seven days after circumcision, and it may take nearly a month for the incision to heal completely. Therefore, after circumcision, it is best for the patient to have sex after one month to avoid the incision opening due to premature sexual life.
