Children have short penises, which can be divided into true and false ones. Pseudopenises are more common, and concealed penises are the most common.
Concealed penis is a common congenital dysplasia and malformation disease, which is different from children's redundant prepuce or phimosis. As you know, after the birth of a boy, the foreskin of the penis always wraps around the head of the penis. By the age of 3 to 4, the foreskin of most children can turn up on their own and the head of the penis is exposed. If the foreskin still cannot turn up or the foreskin mouth is very small, it is called redundant foreskin or phimosis. The concealed person's penis shrinks and hides in the body, and only the pointed small foreskin protrudes from the outside. If you press the skin of the penis inward with your hand, the penis will be exposed, but once you release your hand slightly, the penis will shrink back. Therefore, some people call it buried penis.
Although the appearance of the concealed penis is similar to that of the foreskin, they are two completely different diseases. This is because the outer skin of the concealed penis is not too long, but too short, and the penis is not small but normal. There are three reasons for it. First, the penis skin is poorly developed and too short; Second, the prepuce cavity is too small; Third, the penis skin does not wrap the penis cavernous body, which causes the penis cavernous body to retract without support. If the concealed penis is not operated on, the development of the penis will be restricted if it is concealed for a long time and cannot be extended. Therefore, the concealed penis must be corrected within a certain age (3-5 years old).
