An occult penis is a penis that is covered by excess skin in the pubic area or scrotum, the sac of skin that surrounds the testicles. The penis usually has normal length and function, but it is hidden, hence the name occult penis. Under normal circumstances, there is no occult penis. There are many causes of occult penis. It is mainly due to symptoms caused by other diseases, such as excess fat, and the excess fat causes the penis to be covered and not visible. It can also be caused by some surgeries where too much or not enough foreskin is removed during circumcision. The remaining skin around the penis may be pulled forward, hiding the penis. This can cause this condition to appear. There is also a condition caused by a disease where the swelling of the scrotum caused by the accumulation of lymphedema can bury the penis, and this can lead to a hidden penis. Hidden penis can interfere with urination and sexual life, and this condition can only be treated surgically, while a hidden penis can also cause psychological problems. The main treatment for occult penis is currently surgery to correct it. The aim of surgery is to restore the normal length of the exposed penis, as well as to reconstruct the skin coverage on the surface of the penis. Hidden penis is often congenital and the situation is not common. When this occurs it must be treated in time to solve the physical problem and also to avoid the appearance of psychological problems.
