AMS CXR VS LGX

Postby Ms_Man84 » Thu Dec 18, 2025 4:53 pm

I'm currently considering a revision from a consultant after not being satisfied with the implant I got in Sept 2024.

I had the CXR inserted and feel I not only lost length but girth as well.
This coupled with complications after the fact with a surface infection and further surgery to remove the foreskin (due to it restricting the glans) and lift the glans has left me feeling like something wasn't right.

I've since gotten a second opinion from another more experienced surgeon who said he believes the previous surgeon did the best he probably thought he could do. I don't know if that means he played it safe or what.

He told me he could do something but wouldn't commit to me gaining anymore than a cm following it all. He said potentially I would because the model I have isn't designed for stretching.

He suggested the LGX to replace the CXR. Where he said he might use the existing pump, tubes and reservoir.

He also advised of the risks and potential tissue loss or damage that might leave me worse of than what I am now.

I'm totally torn with not wanting to make anything worse and the potential to get closer to what I had.

I'm going to ring my previous surgeon to ask why he fitted the CXR model because I'm not sure if I had internal scaring or why he used that one.

My question is has anyone here gone from the CXR to another model and if so what were the pros and cons of it?

Also; has anyone experienced any collapse or loss of tissue and been worse off when getting another implant?

If it was me, I would use a VED every day to see if I could reach my previous size. Then, when the surgeon sizes you he can use the biggest implant possible. I wouldn't count on the LGX doing it all by itself.

If you are not obviously undersized (the implant doesn’t extend into your glans, the glans is floppy as a result), then personally I would not do it. For me, a potential extra centimeter is not worth the risks and the time spent sitting on the sidelines as a result.

I don’t have an LGX, I have a CX. But from what I have read on this board the length-extending benefits of the LGX are perceived as overstated.

I say all that as someone not overly-concerned with size. I had a 4.75 inch dick after implantation that eventually got back to a bit over 6 inches, and it made little difference to my enjoyment or really to my partners’.

Everyone is different. If you are fundamentally unhappy with yourself being that small bit shorter, and are willing to accept the costs and risks even if a better outcome is uncertain, then perhaps you want to take the chance. But I wouldn’t.

Leto, I don't think the properties of the LGX are overstated, but I do think some guys have unrealistic expectations.
Or the LGX wasn't the most suitable implant for them for a variety of reasons.
The LGX does expand but it can't give anyone a penis enlargement (neither can any other implant).
As you have said many times (and I agree) you can only gain size up to the limits of your own tunica.
The LGX is simply designed to stretch a bit more in length and girth than most other types.
So it can potentially stretch with the tunica as it recovers and expands through cycling and healing.
But only up to it's own design limits, so correct sizing remains critical for a good result.
I actually think it possibly falls down a bit on girth if anything, but length recovery is fine in my experience to date.

For the OP I agree that you have to weigh up the risks vs potential reward, which may not be much.
Wait and see if anyone on here has gone from CXR to LGX, but I suspect there won't be many.
I'm also thinking maybe get a third opinion if you can.
Ask any surgeon you consult if they have patients who have gone through the same and what were the results.

Downunder, I don’t disagree, obviously there has to be something expanding to allow Boston Scientific to make the claim. But as we also both agree, if properly sized with a CX that growth may be minimal or nonexistent, as your tunica is ultimately a limit on your ability to expand. Doc’s have their reasons for choosing the LGX over a CX in certain circumstances, I won’t pretend to understand to know why, but clearly there are some benefits in a smaller number of cases.

For the OP, I’m concerned about what is happening with the OP in this thread, who went from a regular Rigicon model to an expanding model, but so far hasn’t seen much benefit. Maybe he will at some point. But it is difficult to tell if he will or not, since there isn’t anything to compare it to:

I agree with Tomas, too. If you are willing to go through another surgery to gain a little, you should probably take some time to aggressively cycle and VED use to get yourself in the best position to accommodate a larger implant.

But one could also take the approach that 1 cm is not going to make a whit of difference in anyone’s pleasure, and avoid the risks. Cycle aggressively and use a VED, and at your next revision consider your options then.
