Full length of AMS LGX of 18 and 21 cm

[young_and_impotent]

I think a lot of us had doubts about how the AMS LGX expands. Whether it expands beyond the advertised length. According to this article https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5654325/

The AMS 700 LGX implants became longer with increasing pressures, with the 21cm implant having the most change in cylinder length of 3.9 cm at a maximum pressure of 20 PSI. The AMS 18 cm LGX had a length change second to that of its longer counterpart at 3.1 cm at 20 PSI.

I am not sure if finger strength can generate 20 PSI, maybe someone here can give a better idea.

It would be nice to see a study where they measured length and girth in vivo, say 3, 6, and 12 months post surgery.
I agree that it may be difficult or impossible to generate that much compression. I also experience a marked decrease in sensitivity at high pressures, kind of what I experienced with trimix. I was initially very disappointed with my LGX in both length and girth, but I have seen an improvement ( I havent measured but it seems better) in both over the last six months.

There are many studies on length gains for the titan, the cx, and the lgx.

Going from memory the titan increased length around .9 cm. Cx about 1.1 cm, and ams about 1.2 or so.

The take a way was all three increase length as cylinders get softer over time. The ams does the most but about .5 inch tops.

Deciding factor is how much elasticity you have in your penis. No elasticity no gain. Over time you will probably get some back. Peyronies took me from 7 to 5.5. 10 months cycling titan I was back to almost 6.75. Revision to ams last month i am after 1 month back to 6.5.

After cycling again for another 6 months or so with the added cm length, I should get back to my pre ed and peyronies length of around 7.

If you go through a lot of posts most on here get most of their length back if not their pre ed size.

I got the LGX 21 cm and hope to be able to get back to my 6.75" that I had in the VED prior to surgery. Haven't even measured what I have now, since I just had surgery 5 days ago and there is incredible contraction going on right now due to swelling/healing.
On a related note to regaining length, has anybody ever used a penis extender devices to try to assist with lengthening after an implant? I used one prior to surgery and gained almost a permanent 1" of length from it over about 6 months. Doesn't look like it would harm the implant, since it's gripping the end of the penis with a sleeve that doesn't crush the implant inside/no pinching of tissues.

I would be careful about the potential for pulling your flesh away from the implant. This could create a void which might become an abscess inside the tunica albuginea.

I am not any sort of medical professional, so take my thought as a speculation from a simple engineering-physics point of view.

I am not talking right away, would wait for everything to be well healed, maybe in a few months, the environment should be sterile. Plus any pulling away effect wound rebound right back down as soon as you took off the device, so there wouldn't be any created permanent gap/cavity. Only downside is that it may create a longer penis that the tips then don't go fully up to the mid glans over time and give you a floppy glans. I wouldn't plan on taking things to that extreme, just as much as the LGX would allow me to get length gain wise.

Perhaps a memory that might give insight to the pressure that a bulb might generate. 35 odd years ago. Three wheelers were all the rage. At the time, the big tires just didn't seal to the rim very well. It was very common to have to add air to all the bikes at the start of every outing. We & our kids were out riding with my wife's younger brother & his family. Him & I were prepping the bikes. He showed me the tire pump that he had made. It was the bulb from a blood pressure cuff. He had a short hose with a tire valve stem fitting on the other end. I kidded him that it was way too small to fill a big balloon style tire. He explained that it really worked quite well. I topped off a tire with it. The effort to squeeze it was very low.
In my mind I have a hard time seeing much of a difference between it & the IPP pump. Now true, those tires back then seldom were used at higher than 5-6 psi. But in my mind. If I pro rate the effort that it took to get 5 psi. I believe that 20 psi is easily within reach.
The rules on how hydraulics work escapes me. We had a job at work that required a certain force. The engineering guys measured the diameter of the ram & the psi on the gage to arrive at how much we needed to use. Didn't interest me so I didn't pay much attention.
I suspect that we have members that can crunch the data quickly to see what pressure a small bulb through a small port can generate. I strongly think most of us would be surprised.
Hey, LostSheep. You seem to like research. You want to give it a try?
I'm a bit interested to hear how this turns out.

I am not sure what the exact diameter of my pump bulb is, but it feels like between 1/2 inch and 1 inch.
Half-inch circle (or pump bulb) has a cross-sectional area of just under .2 square inches.
4 pounds pressure on half-inch diameter bulb should generate 20.4 psi
16 pounds pressure on a one inch diameter bulb should generate 20.4 psi

Someone please check my math and physics to confirm I did not blunder my calculations.

I was thinking about ANY TIME. The implant is inside your tunica and suction on the outside of your body can raise a blister on your skin. I am supposing that suction might possibly be able to raise a similar "blister" inside your body as well if your tissues are not WELL-adhered to the implant.

Caveat: As I noted before, his is speculation on my part.

As a side note, I speculated early in my implant research that suction applied to the penis (with a V.E.D.) might make it easier to inflate an IPP (inflatable penile implant) to assist the scrotal pump or even to make the installation of a pump in one's scrotum unnecessary. That no one has done this might tell me something. (Of course, the advantage of no pump in the scrotum is probably less than the disadvantage of having to have an external pump in order to get an erection.)

LS, thanks for the info. I didn't want to give away any clues in my post. You just basically confirmed my hunch. The people choose 20 psi for a reason. The reason was that is about what they felt could be reasonably generated using the bulbs on the market.
