The circumcision of the foreskin must be judged according to the patient’s own situation, not a generalization. The foreskin is longer in infancy and will wrap around the penis, so that the glans and urethral opening cannot be revealed. As we grow older, the penis and foreskin gradually develop, and in adolescence the foreskin gradually retreats backwards to the adult glans can be exposed. If the foreskin still covers the urethral orifice in adulthood but can be turned up to reveal the glans, it is called prepuce, and in this case, if there are no symptoms such as itching, swelling and pain in the glans, it can be observed first, and the patient needs to turn it up often to clean it, so there is no need for forced surgery. If the foreskin mouth is narrow and cannot be turned up to reveal the glans, forming a prepuce, or if the foreskin is too long and repeatedly develops glansitis, it is recommended that circumcision be performed in time to avoid affecting the health of the reproductive system and causing unnecessary harm. If you don’t want to have surgery, you need to pay attention to your personal hygiene and wash your glans and inner foreskin with warm water every day to keep the area clean and dry to prevent glansitis. At the same time, patients should preferably not wear jeans or too tight underwear on a daily basis.
