Circumference changes with an implant

[Hunchback]

Hello,

I am curious how ones circumference changes when using an implant. It looks like implants only "grow" in length (and rigidity but that's harder to measure), judging by videos showing the mechanics. Do they also expand tho, like a dick normally does? If they do, how much is the difference between the flaccid and erect state?

I am really on the small side, so if eventually i do get an implant and lose both length AND girth, it'll be really pushing it :/

You have it backwards. Implants expand in girth from flaccid to erect, but very little in length. The exception is the AMS LGX, which supposedly expands 20% in length, but that doesn't mean it makes your dick longer than it otherwise would be. Really, it just contracts more in the flaccid state.

I have a CX and my implant has gotten more girth, i was 5". and now am 5.25". I did gain .25" in lenght as well. I don't think it will get any longer tho. Thats why it is important to be sized in length with surgery.

You mean that your new "erect" state is kinda your usual flaccid, but while being harder?

No, I mean that your erect length is going to be the same whether you have a Titan, AMS CX, or AMS LGX. But with the LGX, your dick will contract about 20% in the flaccid state, making it somewhat more like a natural dick. A lot of people are under the misconception that the LGX's advertised "20% length expansion" means it'll give you a 20% longer dick than other models, which is false.

Ah ok, so that's what i thought originally. But what about the girth difference of flaccid/pumped, with an implant?

Well...this seems good tho

We've had several threads on just what the length of a LGX does. I tend to agree with your definition but there is a study with a chart showing the measured lengths of 22cm Titans & 21cm LGXs at different pressures. They tested 2 of each model. The 22cm Titan grows to up to 22.7cm using pressures of 0 up to 20 psi. The 21cm LGX grows at the same pressures up to 24cm & 24.9cm.
So saying that the LGX shrinks 20% isn't supported by this study. They obviously state its length at zero pressure & its length at 20 psi. That is 137.9 kPa to the metric members.
So lets throw even more confusion into this. Several years ago. The urologists started using what I think they called "aggressive sizing". I have never seen a definition of this term nor have I seen a start date.
This is just me thinking out loud. But seeing some members reporting short cylinders seems to me to indicate that not all surgeons are on board with this "agressive sizing". Also, having watched a large number of implant surgeries on YouTube. I have a real hard time seeing how a surgeon could mismeasure the penis. Now I will leave open the chance that a surgeon could miss seeing some scar tissue in the penis that caused a false short measurement. Or perhaps a surgeon didn't have the training/skill to carve through the scar tissue.
My advice, I'm not any kind of medical expert. But during your interview with your prospective surgeon. You need to carefully bring the conversation around to how he determines the implant size. Him dodging a full description is not an option in my opinion. Be gentle but insistent. That he takes the 2 numbers, adds them together to determine the implant length.
I say this because I've downloaded the AMS installation manual. As of a year or two ago it clearly states that if using an LGX. That 2cm is to be subtracted from the length total to decide the implant size. So back to a full circle. This subtraction of 2cm's is where I believe the stories of the LGX shrinking back came from. Perhaps even AMS believed this thus put it into writing.
Now for the fear of erosion of a too long implant. That seems to be more of a problem with maleable implants than inflatables. The tissue in the penis head is under constant pressure with a maleable. Perhaps to a lesser degree with a Titan or maybe a CX. The softness of the LGX should make this less of a concern in my opinion.
Please do your own research. I am not giving advice. Merely my opinion that could easily be wrong.
Oh, the surgeon that I plan on using when this Covid crap lightens up on the hospitals around here. He has an rather extensive background in academics. Some of my feelings have come from talking to him. I plan on getting a few more clarifications from him before surgery time.
I wish you all the best luck & thanks for taking the time out of your day to read my post.
