I have an idea for a prosthetic that could potentially lead to reliable and calculable length gain which I do not currently see available on the market. The idea is functionally just an extension sleeve that fits over the tunica and under the glans. The glans and the tunica would have to be separated for this procedure which would normally cause instability within the penis as the glans would be free floating but I think I have a solution to that via grafting that I will get into shortly.
The surgery would have to be a multiple step procedure involving two surgeries. The first surgery would involve disconnecting the Tunica and the Glans and placing the two piece prosthetic inside the glans and the second piece over the tunica. This is where we get to the instability portion as the glans sitting on silicone would slide around. My idea to solve this issue is to have a mesh on the outside of the glans insert that contains tissue grafts so the glans will create an organic bond to the glans insert. This insert will be about 1.5-2" long instantly adding 1.5-2" in length. The reason for this size of insert is so the patient can stretch out the soft tissues of the penis utilizing a constant traction device called an ADS. I have personally worn an ADS for 16 hours a day for 2 years straight and found means to make it so comfortable that you do not even notice you are wearing it.
The tunica sleeve would need to be secured as well and would run the entire length of the tunica. The attachment idea is roughly the same but in reverse where there could be the mesh on the inside of the tunica sleeve in addition to there being a small insert inside the end of the tunica to allow dissolvable
Sutures to be used to secure the tunica to the sleeve so it has enough time to adhere to the graft.
The tunica sleeve would need to be a much softer silicone then the glans insert since the glans insert would need to be mostly rigid all the time to allow for normal erections but the tunica sleeve would have to be softer to allow the penis to hang and not have it look like you have an
Erection all the time. The patients own Tunica would provide the
Erect rigidity for that section of the penis while
Erect.
During the stretching process, before the two sections are connected, the patient would stretch the soft tissues past his ideal length goal and then the two sections would be connected which can be done without surgery through different mechanisms within the prosthetic. A simple push and twist lock could be designed into the device so that the device can be connected while not stretching and then detached when stretching is needed.
If this worked, it could lead to theoretically limitless length gain with a fully functioning penis with no reduction in sensation.
This is just an idea and I am not a doc. I invest into medical startups regularly and this idea just came to mind. Please critique this idea and let me know of potential problems with the design or idea as a whole or feel free to steal it and make it yourself. This could radically benefit those suffering from micro penises as well as just be a relatively straight forward means to increase both length and
Girth as well as increase glans size based on the size of the glans insert. I have some rough cad files of the inserts but they functionally just look like a tunica with mesh around it for the glans insert and a tunica with a flat head for the tunica sleeve.
Let me know of any ideas or critiques please!
