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!

It's interesting for sure, but to be quite frank, seems highly invasive. There is a strong correlation between invasiveness and complications when it comes to penis surgery.

I completely agree with you on that. The less invasive "length" surgeries are unreliable at best and kinda disfigure the penis. The ligament cutting as an example is mild but makes erections hang at really weird angles. I am not sure how actual length can be added without a rather invasive procedure.

What complications can you see coming from this operation?

I've been told the erection angle change on Ligamentolysis is a myth by a few surgeons. Obviously they could be saying that in order to pitch their procedure but I don't have a reason not to believe them. Lengthening progress reports are exceedingly rare, so even one mention of a change in erection angle would make it impossible to tell if it was a rare complication and we just have poor sample size, or a common complication that we just can't ascertain.

As for your surgery idea:
For one, I'm not sure how or what you mean by putting a sleeve "into the glans." The glans are about as tricky as they come when enhancing cosmetically, what you propose sounds like it could cause some damage. Maybe you can explain this better?

How does this differ from the Penuma or LEEP procedures on a fundamental level? I'll be frank, while it doesn't seem to be either Penuma or LEEP step-for-step, it shares some conceptual features which raise an eyebrow, given how inherently flawed Penuma & LEEP are.

To be honest, a sketch or drawing of this would make it a bit easier to digest. I think I follow what it is you are trying to do but not sure I'm wrapping my head around how this would "provide limitless length."

I'm not knocking your idea, and I think it's wonderful that we remain creative, but when it comes to the history of male Phalloplasty, invasiveness + synthetic grafts have a notoriously poor track record. Yours has to eliminate this recurring trend.

What exactly is the recurring trend of synthetic grafts you are referring to?

So you know how the tunica looks like two tubes with pointy ends that attach to the glans? It would functionally be a copy of a tunica that goes between the patient tunica and the glans and is grafted via human tissue grafts to the synthetic tunica extension. The human graft tissue will be embedded into the synthetic tunica through a mesh so that the synthetic tunica and the patient tunica can bond and heal naturally as one single piece unlike just simply putting a sleeve over the tunica.

The patients body will create strong organic bonds to the implant on both the tunica end and the glans end.

The surgery would be as follows as I feel this will help with explaining what I am trying to say.

1. De-glove penis
2. Detach glans
3. Separate urethra from tunica without severing
4. Place tunica extension between patient tunica and glans
5. Secure extension to glans and patient tunica to allow the patient tunica to heal to the imbedded grafts in the tunica extension as well as the glans to heal to the tunica extension
6. Penis is re-gloved

The surgery would then be over. The shaft skin on the penis would have to be stretched leading up to the surgery unless the patient has their Foreskin intact then no stretching may be needed.

When I was referring to "synthetic" I was talking about PLGA Scaffolds which I haven't heard performed in ages. I suppose it's still plausible this avenue could work (PLGA) but not enough was advanced in that direction to see anything come of it.

Your idea is certainly interesting but no doubt on the "highly-invasive side" as far as male Phalloplasty is concerned. I think perhaps reaching out to surgeons that perform transgender reassignment surgeries might be more effective; I suspect they'd be more accommodating to such intricacies, and probably have clientele more open to "experimental modification."

Men have reported Flaccid and erect length through simply severing the suspensory ligament + a stretching regimen -- it just seems that your concept would need to demonstrate high efficacy + remarkable gains (guaranteeing in excess of 1.5" erect length) to justify it in my mind.

No doubt interesting, I think you should do a draw-up of it as well, some of us tend to be more visual learners, especially as it pertains to dissecting anatomy.

Did I read that correctly? Detach glans, as in, remove the head of the penis? The potential to lose your penis just sounds way way too high for this to ever be attempted. Sorry if I'm misunderstanding your idea though.
