Imagine there! But the reasons are completely different. More precisely, the main ones are two.
The first is the large penis itself, this is not only rare, but usually it does not cause discomfort. And in this case, the issue is solved as follows: the tunica albuginea covering the corpora cavernosa is plicated (assembled with special sutures) by creating symmetrical duplications, using non-absorbable suture material. After such an operation, the penis decreases both in diameter and in length.
But the second reason is a disease that is popularly called "elephantiasis", while lymph flow from the lower extremities and external genitals is disturbed organs. In this case, the surgical intervention is of a different nature. First, the skin is prepared in advance in the most thorough way, eliminating the existing inflammatory changes. A few days before the operation, the scrotum is lifted and held in this position, treated with antiseptic agents in the form of emulsions, ointments or creams.
The essence of the technique is to remove the pathologically altered skin of the penis, foreskin and scrotum and replace it with healthy, taken, for example, on the upper-lateral surface of the same scrotum (in this place the integumentary tissues are less subject to changes and therefore suitable for closing the testicles).
Yes, of course. There have been such cases. But a large penis is less common than a large breast, so such cases are rare. However, many men who enlarged their organ through injections then wanted to return everything back.
