Making a bionic penis a reality!

Donate to The Bionic Project and WIN!

Oh yes, the future is bright!

There have been rumblings in the Willitorium, of developing a very high-end prosthetic that would mimic the natal male anatomy more closely than anything that’s ever been available. Imagine a bionic penis that serves four functions: pee, pack, pleasure and play – over two states: flaccid and erect.

This ambitious project aims to alleviate body dysphoria and offer a viable alternative to existing surgery options.

Having been in talks with several prototyping and engineering studios, I am happy to report that the findings have been very encouraging. The technologies that would be required for such a prosthetic essentially already exists but just haven’t been applied in this way before.

To date, trans men have always been the accidental beneficiaries of technological advancement created for natal men, who are anatomically quite different to transgender men. That’s about to change. This project is very much about utilising the anatomical differences to our advantage. How? Let me give you an example. A trans man (assuming he has had no lower surgery) has easy access to pelvic floor muscles, which a natal male does not. No one has ever developed anything that would utilise these muscles to actuate an erect state. This would require a controller no larger than a regular tampon and just as easy to insert, versus the highly invasive surgeries to place reservoirs into testes that must be operated by hand.

I am a firm believer in the sharing of ideas and knowledge, so I intend to be open and transparent about exactly how I envision the Bionic functioning – from concept to production – so that others can get excited, get behind me and help make this a reality.

Up until this point, all of Transthetics’ product developments have been funded by sales, but on this project, I will need the enthusiasm and help of others who believe in the importance of making the Bionic a very tangible reality.

So please give what you can and know that EVERY donation is hugely appreciated.

    As the discussion on the semantics of gender and gender identity was off topic and becoming inappropriate and aggressive, I have deleted these comments. These kinds of discussions are more appropriate in a political/sociological arena rather than a scientific one, where distinctions between specific physicality is necessary and appropriate.

    Okay … I’ll try to find a way to donate if I can. This sound very interesting. Just one question:
    Cut or uncut? I realize a lot of guys probably don’t care, hence why uncut versions of what you’ve already got are on your backburner. But to me, it’s fairly important.

    • Alex May 10, 2017 at 7:44 pm - Reply

      Most likely it will actually end up being uncut in its flaccid state and then in erect state, the foreskin will roll back, exposing the glans.

    You mention using kegels to obtain an erect state. Would there be an alternative for those that don’t want to/can’t have anything “inserted”? I always imagined something like a pump they use in phalloplasty but on a prostetic.

    • Alex May 11, 2017 at 2:20 am - Reply

      Yes, I imagine it could also be operated by a discreet remote controller for those that don’t have easy access to pelvic floor muscles, but then it’s reliant on you carrying the controller. Basically, the controller would just release a valve that would force liquid from one area into another.

      No. You can get more detailed info here it’s a pee, pack, pleasure and play device that will use a controller to move between flaccid and erect states

    Hello, not sure if my 2cents will help, but I am an engineer and I have been thinking about doing a project similar to this one but have not had the time to design it out. I have thought about placing a touch sensor along the side of the shaft or in the head and building a circuit the size of one in a USB drive that is equipped with a microcontroller/microprocessor that will process the rate of stroke speed and pressure to determine if the wearer is attempting to become erect. Example: If the wearer is engaging in self play or being stimulated by a partner when the stroking motion is consistent at a certain rate then the touch sensor (not sure if a resistive or capacitive one will work best) will then signal the microcontroller to turn on another circuit that tells fluid stored in the testicles to be pumped up to the shaft so it can become erect. This is just a theory I haven’t done the circuit analysis yet but if I can develop a circuit schematic I will send it your way. Best of luck. I will be one of your first customers.

    • Alex May 11, 2017 at 5:46 am - Reply

      This is great! Sounds like we may be thinking along similar lines with micro controllers, controlling fluid movement. I’m just thinking of different actuation (ie gentle Kegel muscle squeezes to tell the controller to kick in) If you are open to it, I’d love to send you a private email to run some stuff by you and get your thoughts and input :)

      • KBTHEPROFESSOR May 12, 2017 at 2:12 am - Reply

        Yes, that will be fine.

    • Julian May 12, 2017 at 3:54 am - Reply

      I find the idea of stroking it to become hard a lot more appealing than kegel muscle squeezes fwiw. I’m sure I’m in good company here with the whole insertion thing being a serious aversion. Based on what Alex said in response to another message, that it would be uncut and then the head would be exposed when hard, stroking it to that state sounds right and perfect to me. Also one of the major issues with all stps on the market is they don’t FEEL like a flaccid penis, and that’s been really discouraging.
      Just laying out some thoughts since the idea is to create something that is a plausible alternative to surgery.

      • Alex May 12, 2017 at 5:38 am - Reply

        Yes I absolutely agree! If that is a possibility, then it should most definitely be explored! :)

      • Matt May 24, 2017 at 9:03 pm - Reply

        I agree with the strokes thing, obviously it depends what’s possible but that would feel most real to me, and inserting things *there* is just a no for me anyway. Hopefully it’s a realistic possibility :)

    Oh wow, I’m really looking forward to this project! As a trans man who has never cared for the idea of having bottom surgery, this would be an extremely wonderful thing to have. Out of curiosity, do you happen to have a ballpark idea of what the Bionic would cost when it’s released? (That way I can start saving early, haha.)

    • Alex May 11, 2017 at 10:14 pm - Reply

      It’s really hard to say at this point, but safe to say, it won’t be cheap, though only a tiny fraction of the cost of lower surgery. I’m also hoping to be able to get insurance companies to cover the cost of such a device as a necessary medical prosthetic. In some countries, like Germany, this is already the case.

  11. Tessa May 12, 2017 at 1:35 pm - Reply

    Hey Alex!

    Wouldn’t it make more sense to connect the ejaculation reservoir to a Kegel trigger? That way the Bionic could ejaculate through contractions during orgasms…

    I’m also no big fan of triggering the erection over an insertable remote. I like KBtheprofessor’s idea better for that purpose as it seems more natural.

    • Alex May 12, 2017 at 3:53 pm - Reply

      Hypothetically, it definitely would. It’s just a case of what’s possible in the very limited space there is. I’m not entirely sure it’s possible to have one controller in the shaft, as well as the spongy erecile material, as well as a hollow shaft to allow urine to pass through, let along two. I suspect the idea of hiding a controller WITHIN the device, though it’s a very good idea, will be extremely challenging, hence my thinking of keeping the controller external to the prosthetic, either as a tampon insert or hand held device, but hearing these thoughts and inputs is really great! Keep them coming!

      • Rynbo January 2, 2018 at 12:44 pm - Reply

    • Alex May 15, 2017 at 11:49 pm - Reply

      There will be a few options and it will be up to the user to choose. The most non invasive will be to use it with adapted underwear much like the Bono, but we are also looking at magnetic attachment options which would still be minimally invasive ie essentially getting discreet magnetic piercings in specific locations that the prosthetic would then snap on to. This is based on the Cochlear Vistafix system. (Just google that and you’ll get a clearer idea.)

        Oh wow that sounds so awesome! Much better than having to use an adhesive!

  14. August T. May 19, 2017 at 5:32 am - Reply

    I’m so happy to see this in the works :) it’s about time! Oddly enough, I’ve been trying to build something just like this over the past year. And by build I mean I have plans but no money. I’m guessing a harness would be needed? If yes, a good idea is to make then skin colored. I haven’t seen those tbh. Also a good reference to look at is the company Orgasmatronics. They actually created a touch sensitive dildo under creative commons license. There are multiple ways of doing it, but one way is to have an open channel in the prosthetic to where, when touched, it changes the pressure inside, which feeds through to an airtight chamber (via tube), and a pressure sensor senses the change. That feeds to an arduino, which basically dictates that more pressure = more power to the vibrator. Of course there’s the issue with the tube but I think it’s possible to hide it within the prosthetic and harness if you find this is the route to go. Now I’ve seen another commenter say sensors along the shaft. If they mean force sensors, then that might be tricky. Force sensors, when encased in silicone do not work as well as they could. I believe it’s doable, just takes a lot more coding a’s they measure force in quintillions+ as a base. Not to mention packing would be difficult if it’s embedded in the silicone (over time make ruin or break it). So… my thought is that the sensors that need to be in contact with the prosthetic would sit in the balls or base, while everything else would sit in a airtight container. Basically like something that would attach to the harness with velcro, and in a way where it’s like a portion of the belt. Yknow what I mean? Along with that could be override switches lol to turn it off. I could certainly dig into my notebook for anything else if you’d like, but that’s all I recall for now :) like I said I really wanted to make this a reality myself, so if I can help in any way then I’ll consider that research a success. I certainly don’t have the means or connections to do it myself. I think you may be the perfect person to figure it out though :)

    You might also have a good amount of success through kickstarter or youcaring. I’m curious about the cost of stage 1 though, as I would have thought stage 2 would be the real cost. Stage 1 is just planning right? So I guess I’m just wondering why the funding goal is so high lol

    • Alex May 19, 2017 at 11:11 pm - Reply

      Unfortunately kickstarter wouldn’t host this as they deem it to be an “inappropriate product” and yes, I’m most definitely hoping to be able to complete stage 1 in under $50,000 and roll the extra into the next phase, but I also wanted to make sure that there’s solid enough interest first. I will be updating on progress in the coming weeks with much more tangible information to put people’s minds at ease, as I know some people are reluctant to donate at this stage as they feel it’s not fleshed out enough yet. However due to finishing up some patent specifics, at this stage I’m still forced to be a little vague.

    As a pre everything trans guy who doesn’t want to go through bottom surgery but still wants a penis, this is perfect! I wanted to ask about the lubrication/ejaculation reservoir. Will you be able to simulate authentic ejaculation with the bionic while masturbating and/or during sex?

    • Alex June 7, 2017 at 10:12 pm - Reply

      It’s unlikely, but it will be something we will explore. I’d love to say yes, but also don’t want to over promise.

  18. Mason June 17, 2017 at 8:13 am - Reply

    If it’s alright, I have a few questions! One being that I noticed somebody mentioned the stroking feature, is there any way that it could possibly be input to such a thing? Also, when the muscles are triggered, will it instantly erect or slowly get to its position? One more thing, my apologies if this a weird question or a dumb one, but how would the wearer experience the pleasure done to the penis? It says that it “Stimulates the wearer‘s erogenous zone”, but could you elaborate please? Also, either way, I think all of this is such a wonderful idea and I encourage your work!!

    • Alex June 17, 2017 at 3:20 pm - Reply

      It would be similar to the way your smart phone registers touch and then responds with an appropriate action which in this case will be to tell the unit to become erect, and again, we want it to mimic natal anatomy, so it won’t just BOING into a solid object ;) re stimulating the wearer, it will have a silicone nub that will press against your natal anatomy, possibly also vibrate much like the Bono.

    When did this idea come about?

    • Alex July 19, 2017 at 4:00 pm - Reply

      The idea? Probably when I was about three years old. But I first started putting wheels in motions on initial research and feasibility and first talking about it publicly a bit over a year ago, and started the ball rolling seriously a bit over a month ago.

  20. Moose July 19, 2017 at 4:03 pm - Reply

    So, just wondering but if another transmasculine person was able to create something similar to this, but fairly different or possibly improved, would you want to work with them or sue them? I ask because in it’s current conception, I wouldn’t consider this product to be a match for me in every aspect needed. I don’t want this to end up like those prosthetic companies that end up having beef. Like this is to improve the lives of trans people. Yknow?

    • Alex July 19, 2017 at 4:37 pm - Reply

      I’d want to work with them. I do have a patent pending on it, but this technology needs to exist, and I’m certainly not doing this for the money. I’m doing this out of personal need and if someone else had already created a product like this or better, then I’d be very happy to not have to embark on this hard slog. If you want to run anything by me, feel free! :)

    Hey Alex!

    After seeing the initial renderings I have a bit of an issue with the placement of the ball sac. It seems like it would end up right between the wearers legs instead of hanging in front of the body. Is there a specific reason for this design choice? And will you try to find a more “realistic” position for the scrotum or is this the final concept?

    • Alex July 20, 2017 at 11:38 pm - Reply

      These are currently just concept sketches so no, this is not what the final will look like.

    Hi, I found out about this project a little while ago and I’m super super excited about it!! I was wondering, considering how expensive this is going to be, are there any plans for any sort of warranty? I’m just thinking of how clumsy I can be, and I’d hate to have to spend another long while saving up for a replacement. I’ve scrolled through the comments and seen you talk about the possibility of insurance covering at least some of it, which would be AMAZING, but I still worry about any roadblocks I might hit with insurance and having to pay out of pocket or something along those lines. (Trying to get top surgery has been quite a process so far :/)

    Also, how waterproof do you think it will be? Are you thinking of making it waterproof enough for swimming, or is that out of the question? (Not that swimming with it is my first thought, but again, I worry about accidents that may be bound to happen.)

    Thank you so much for all the work you’re putting into this product!! Actual bottom surgery is both way out of my price range and also sounds fairly terrifying to me to be honest, seeing this project in progress means a lot to me!

    This looks super exciting. I’m wondering about the stimulation nub.

    For me I would prefer something that went both sides of my bits, rather than a single nub that pressed straight down. This would give a bit of a feel of being inside, which would feel better for me.

    I don’t know if that’s something that could work though.

    Thanks for all the work you’re doing on this!

  24. TJ October 6, 2017 at 7:20 am - Reply

    ^ same here. I feel like me and a nub are sword fighting and I’m losing the match, every time; like something is stabbing at my most sensitive bits. Nothing fun about it at all – making the pee tube entrance a place smooth/inviting enough that we can insert the little guy as we insert/play with the big guy would be far more enticing to me. I love the concept and the potential collaborations I’m seeing in the thread, keep up the good work guys!

    • Alex October 6, 2017 at 11:44 pm - Reply

    I cannot wait for this product. There is no doubt I will save as much money I can to buy it.

      We’re aiming for average in both flaccid an erect states so yes size will change. The idea is to get it as realistic as possible.

    Hey Alex! Have you heard of the company reelmagik? They have moveable foreskin and 3d testicles on their models and other stuff. And their products are super real looking. there is also a company called “the ultimate prosthetic” but they are a scam (rip) they seem to have been able to make moveable foreskin on their prosthetic as well (the one they won’t sell lol) they have a demo video showing it off as well as manual ejaculation by squeezing the left ball (Reelmagik is NOT the scam website to clarify) but that other company is known to be rumored for being scammy, the reason I brought it up is because (maybe you could get ideas from their demo model? (Or figure out how they did that?) it may not be much help but I look up your website everyday to see what has changed and if I find anything that could bring you guys ideas and help you guys out I’ll be sure to bring it to you so you can help the community.

      In checked luggage, no problem at all. In hand luggage, even if security sees what it is as it’s going through the scanner, that’s not what they’re looking for (as dicks are thank fully not the terrorist’s weapon of choice) and would have no reason to pull your bag aside. And yes, you can swim with it, but not in chlorinated water as that will shorten the life span of the silicone.

    Listen, I realize that this forum, and the products in development, is designed to address the needs and concerns of trans men. But please consider this: the overwhelming majority of men who are living with psychological trauma concerning their penises are NOT trans men, and when researching possible solutions to address these traumas, their concerns should count for something also.

    Let me provide you with a small, random sample list of problems faced by enormous numbers of men:

    *Chronic and untreatable ED caused by Type I Diabetes, Neurological conditions (MS, Parkinson’s, Paralysis, Head trauma, Strokes, etc)
    *Circulatory abnormalities caused by Cardiac disease, occlusion of veins, arteries, or capillaries due to metabolic disease, congenital malformations, aging, genetic vulnerabilities, etc.
    *Men born with a “micro penis” rendering them unable to have sex or satisfy a partner
    *Men born with small penises, which often leads to bullying, shame, body dysmorphia, etc

    So if you cared about human suffering in general, as opposed to only caring about suffering within your own community, then a bionic penis(es) should be developed that can also be placed surgically, like a limb prosthesis, to address the needs of non-trans men. This bionic penis should ideally give men natural sensations, a range of size options, erections and deflations whenever they are desired, and of course the ability to urinate normally.

    Not only would the development of such a prosthesis address an enormous amount of human suffering, but it would result in it’s developers becoming among the wealthiest people on Earth.

      These are all important points and I do anticipate that what we create will be adaptable to natal males also. At present, natal men do have a lot more options available to them for the treatment of ED, be it through drugs or surgery and other disease and congenital malformations than trans men do. Trans men have always been the inadvertent beneficiaries of treatments designed for natal men, and it may just be that for the first time in history, it ends up being the other way around here. I’m sure you’re aware of the surgical options currently available such as this Also, there are very encouraging advances on lab grown penis and penile transplants that will definitely be available for natal men in the near future that will, sadly, in all likelihood not be options for trans men for a long time to come. (see and What I would like to see is a multitude of viable options for ALL men who have penile issues and I’m just doing my small part in starting to address some of these problems.
