What are the disadvantage of 41 old man to do circumsision ?

Adult circumcision: The procedure for an adult requires good anesthesia and an operator that is experienced. There is extensive suturing (stitches) that are placed and like any other wound,it is uncomfortable while healing. Keeping the area clean and avoiding trauma to the area while healing is important.

Surgery Risks: The first question to ask is why is the procedure being performed? Risks with cosmetic surgery have greater significance compared to risks when the procedure is being performed to avoid or reduce risk to life or penis. Generally all surgery has risks of infection, bleeding, poor wound healing, incomplete surgery, need for repeat surgery etc, etc, etc. Risks are very low but only God is perfect.
