How old can a child turn out his foreskin? Generally, children can turn up their foreskin to reveal most of their glans before they reach school age, but there are some children who are unable to turn out their glans because of scarring prepuce, or if the prepuce is relatively tight. This time, we need to go to the hospital for foreskin expansion surgery or circumcision, because long-term scarring of the foreskin will cause urine to soak the foreskin and glans for a long time, forming chronic inflammatory stimulation, and some children will also cause urinary tract infections. So pay attention to this problem in your child, and make sure you start from the head. When the frequent redness should be noted whether it is tight, whether it can be upturned, if it can be upturned, the foreskin scale in it should be cleaned frequently to prevent infection. There are some children, because of the chronic inflammatory irritation caused by scarring prepuce, can only do surgical excision, and foreskin expansion surgery can not solve the problem, because it has lost the elasticity, there is no separation to be able to expose the situation, it has formed a scar, so only surgery, can not choose the conservative expansion treatment.
