In the past year, I often encounter anxious mothers with their children in the male clinic, asking: the child’s penis is very short, it looks like there is no, only a layer of skin, the penis will be erect when there is urine, will also become longer, but with the growth of age, or so, this situation should be how to treat it? What should I pay attention to now? There are also some young men in my male clinic consultation: why their penis is short, and like the “turtle head” shrunken under the skin, the appearance of cold weather can not see the penis, is not the foreskin is too long, should not be circumcised? In fact, the penis is short, there are real and fake, among which pseudo-penis short is more common, and this pseudo-penis short is the most common in the occult penis. Occult penis is a common congenital developmental abnormalities and deformities, and pediatric circumcision or prepuce is different. As we all know, after a baby boy is born, the foreskin of the penis is always wrapped around the head of the penis. By the age of 13-4, the foreskin of most children can be turned up on their own and the head of the penis is exposed. If at this time the foreskin still can not be turned up or the foreskin mouth is very small, only then is it called prepuce or prepuce. In occluded cases, the penis body is shrunken and hidden inside the body, and the only thing that protrudes out is the small pointed foreskin. If you squeeze the skin of the penis inward with your hand, the penis body will be revealed, but once you let go of your hand, the penis body retracts again. Therefore, some people call it a buried penis. Although occult penis looks like circumcision, yet they are two completely different diseases. This is because the outer skin of occult penis is not too long, but too short, and its penis body is not small but normal. It occurs for three reasons: first, the penile skin is stunted and too short; second, the foreskin cavity is too small; third, the penile skin does not wrap around the penile corpus cavernosum, causing the corpus cavernosum to retract inside the body without support. Therefore, if a man has an occult penis, circumcision cannot be done easily because the surgery of occult penis requires the use of the inner layer of the foreskin to supplement the skin of the penis, and if circumcision is done, it will make the correction of occult penis more difficult. So when is the best time to perform penile correction surgery on men? In our questioning of some parents of affected children, we found that some parents had a similar condition of the penis when they were children and it slowly normalized when they grew up. Therefore, unlike circumcision which has a greater impact on people, the incidence of occult penis has a tendency to gradually decrease or even heal itself as the child grows older, and not having surgery in the early stage of a child with occult penis does not have much impact on his penis body development. Therefore, we do not advocate early surgery, and can postpone the age of surgery as much as possible until the child is 12-14 years old.” At that age, the level of androgens in the body begins to gradually increase, the penis develops faster, the appearance of the penis changes more, the lining may be affected by the hormones in the body from thick to thin, while the fat in the pubic symphysis area and the root of the penis is redistributed, plus the erection of the penis increases at this time, which also plays a role in repeatedly pulling on the lining, making it longer and thinner, restoring elasticity, and the appearance of the penis body gradually becomes normal, which will also become a critical age for the child’s occult penis to heal itself. If the recovery is not satisfactory, surgical correction is also possible. Although it is said that most occult penises can slowly heal themselves, parents should tell their children to pay attention to personal hygiene and to reveal the head of the penis every day for careful cleaning, so as to ensure that their children are protected from bacterial infections and to make his penis development healthier. The treatment of occult penis is completely different from that of circumcision, which involves removing the overly long foreskin (i.e. circumcision), while the treatment of occult penis involves surgery to enlarge the foreskin and thus lengthen the skin of the penis, and also to “pull” the spongy body of the penis out of the stomach and fix it well so that the penis In addition, the penile corpus cavernosum should be “pulled” out from the stomach and well fixed so as to restore the normal physiological anatomy of the penis, thus achieving the purpose of facilitating penile development. However, if the anaphylactic penis is misdiagnosed as prepuce and circumcision is performed, the result will be that the already short penile skin will become even more short, and once the postoperative penile corpus cavernosum is deprived of skin attachment and protection, the penile body development will be more and more inhibited.
