This Friday, a father and son came to the clinic with anxiety. The father and son went to the swimming pool to work out, but in the locker room the father overheard that his 12-year-old son’s ding was small, which scared the father, so he rushed to the hospital’s male clinic with his son. After detailed questions about his growth, development, diet, and physical examination, it was found that in addition to a little fat, the son’s small ding is actually well developed, but because it is too fat so that the small ding are hiding to the subcutaneous fat inside, so from the appearance of the first glance, ding small. In fact, this kind of situation is more common in urology/men’s clinics (even pediatric urology clinics). So what exactly is considered penile dysplasia? When should moms and dads be vigilant and bring their children to the hospital in a timely manner? Today we’ll talk about the little dingus that we all care about. From the moment a baby is born, the obstetrician/pediatrician who delivers the baby will examine the baby to see if the scrotum is enlarged, if the balls can be felt in the scrotum, the size and shape of the penis, the location of the urethra, and so on. The pediatrician will also examine the baby’s external genitalia during the baby’s regular future pediatric visits to assess whether they are developing at the right age. Due to various congenital or acquired factors, some male babies have dings that look particularly small as they grow and develop. Some of them really have problems with penis development and need to be properly examined for endocrine and genetic conditions; some are male babies who have not yet reached puberty, so they can continue to wait for observation; others are over-nourished and overly obese, making the normally developed penis deep in the lower abdomen, especially under the prepubic fat, and as they grow older, the fatty tissue gradually decreases and puberty develops, and the penis shape partially Some male babies have a disease called “occult penis” and need surgery. There are three types of occult penis according to different causes: Buried penis: The normally developed penis is hidden in the thickened prepubic fat, often due to congenital developmental abnormalities. Webbed penis: the skin of the scrotum extends to the ventral side of the penis, and the connection between the penis and scrotum is abnormal. Bound penis: due to the formation of a circular scar after circumcision that affects the extension of the penis, often accompanied by syringomyelia and hernia or due to buried penis, webbed penis only simple circumcision. If there are several situations mentioned above, moms and dads should go to a regular hospital and consult with a professional doctor to see if their male child has any problems and needs surgical treatment. As long as it is treated properly, it will not affect the growth and development of the male child and his future sexual function.
