I have immense respect for Dr. Trost, both for his medical knowledge of male sexual health and for his personal values as a service-oriented human being. He knows few, if any, equals in this regard.
I also have immense respect for Dr. Eid, both as a great surgeon and an incredible person. One is the leading implant surgeon in the world, and one does not perform any implant surgery. There is no doubt unavoidable inherent specialty bias with both of these men because ... they are human.
While I can believe that Dr. Trost suggested like; Michael Jackson, there are a limited number of surgeries you can have before you run out of options. I have to doubt that Dr. Trost meant to suggest a man's penis would begin to deteriorate and be misshapen like Michael Jackson's nose. Every surgery on a nose operates on the tissue forming the nose more like excision and grafting. That tissue is altered and reshaped. Tissue is removed and added. Structural cartilage is removed and transplanted. Nothing like that happens with an implant. No tissue is ever removed. In the first surgery, the cavernosa tissue (like a web or sponge) is pushed aside in the chambers to make room for the cylinders. Subsequent surgeries remove cylinders from the chambers, and new ones slide into the capsule. The reservoir and scrotal pump are replaced. Often the old reservoir is deflated and left in place. I have known men with three surgeries (2 revisions). Their penis looked perfect, and they gained some modest size over the first implant.
None of this suggests that men can have 9 or 10 implants using today's materials and methods but even a 6th implant would be at least 40 years down the road. That assumes you average less than 7 years per implant. It also assumes you live 40 years and that implants and procedures do not improve. The internet is a vast place. I challenge anyone to produce a photo of a penis that has an inflatable implant currently installed that is atrophied or misshapen because it was one implant too many. Being that anything CAN happen, there might be one or two on the planet. However, I am willing to bet that it is like the case of a misshapen guy with one implant. The surgeon faltered, or there was a severe infection.
NOW FOR THE REAL ARGUMENT - we have been here before but I will lay it out again because no one ever has a comeback.
Even if the false analogy to Michael Jackson's nose was accurate, this is NOT a medical decision for young men with a non-functional penis as much as it is a philosophical decision.
Young guys with a functional penis should NOT be getting implants. No one should even have to discuss this.
However, if a young man does not have a functional penis and avoids an early implant because he wants to save his penis, one has to ask the obvious question -
What is he saving his penis for???A penis is a usable body part, not an heirloom. Is the goal to die with a perfect penis or to live with one? Is the goal to have a functional penis at 80 or at 30? Is the goal to get killed in an auto accident at 30 or from a tragic brain tumor at 40 waiting on your first implant, or is the goal to find a wife and raise a family at a time when a penis is essential to these life events? If your penis is non-functional, and you wait until late in life to have an implant not only do I hope you have a great penis at 80. I hope you have great knees, a great back, great eyesight, and great general health because you are sure as hell are not going to have any family to rely on.

The philosophy that says a man in his twenties should wait at least until his 40's to have a functional penis is a philosophy that strains one's power of reasoning.
