Many children visit the clinic for short penis appearance, and most of their families have the mentality that a simple surgery can improve the appearance of their child’s penis, thinking that it is similar to “circumcision” surgery. In fact, because of the substantial improvement in our material living standard, many male children are over-eating and exercising less, resulting in obesity, uneven distribution of body fat and fat accumulation on the pubic symphysis. Therefore, a large proportion of the children we see in the clinic are not really “occult penis”. Occult penis refers to the narrow opening of the foreskin, the foreskin cannot be turned up to reveal the glans, and the penis body is buried in the fat in front of the pubic symphysis.
