AMS 700 expansion

[Matthew]

I hear things like 15 to 18% expansion rate for the AMS LGX 700 unit. What is that based on? I mean 18% of what? At 6 weeks I will probably get inflated as much as possible for testing. Does this mean it will grow 18% beyond that? Where do they zero out to get % data from is my question. For instance, I have 18x12cm units with 2cm extenders. This is a total of 20cm. Does the % expansion mean 18% beyond 20cm? Anyone?

I have a Coloplast Titan, so I'm certainly no expert. My research from before I had an implant was that the 18% applied to the uninflated cylinder itself. So your 18cm cylinder is the unexpanded, uninflated length. Max expansion is 18% addition to that. Of course, you have 2cm of RTE's too which add to length, but the RTE's don't expand. So, 18% of 18cm in addition to your 20cm, or roughly 3.2cm in addition, or 23.2 in total.

That said, the AMS operating room manual recommends that the LGX be sized 2cm less than the measured length of the cavernosa, whereas the CX is fully sized to the cavernosa. This would help make your flaccid 2 cm smaller, and perhaps more "natural" than the comparable CX (or Titan). Of course, individual docs don't have to follow that recommendation, and perhaps many don't. But, if that is what they do, your maximum growth potential beyond the initially measured cavernosa size will be 2cm less than the 18%.

How much expansion you actually get will be a function of your body. When I talked to the AMS rep (Elizabeth??) last November about expansion potential she was backpedalling furiously and repeatedly saying that it was a theoretical potential, and how much is realized depends on the patient.

The "18%" figure (2.0 cm) as rlm1818 states is the differece between deflated and inflated ... in the below image you will see one cylinder inflated and one not. If you look closely at the ruler you will see the "2.0 cm" (18%) increase ...

Forgive me for my ignorance but this is even more confusing for me now. Are you saying that the Titan and CX are fully expanded length and never need pumping up? I would think all units would expand to a certain length. I thought the whole purpose for a reservoir on ANY unit was for expansion. So if a guy had a titan unit and was 7 1/2" long, he would walk around with a non erect penis hanging 7 1/2" down? In light of "inflated" vs "deflated" 18% does not seem impressive to me. Again forgive my slowness. Maybe I will come around with more education.

I went through the operating room manual on the AMS 700 LGx and on the CX. AMS does not recommend sizing the implant 2.0 cm smaller than the corpus. They have two ways of sizing the implant body (the part without the extenders). One method uses 2.0 cm of extender to place the "fill" tub closer to the incision line and one uses the full size of the corpus.

The 18% figure is for possible inflation of the implant. The flacid length of a flacid implanted penis is determined by the size of the implant cylinders. Be prepared to have a showy flacid state. Using the AMS literature, to size an implant you take the size of the corpus, pick the nearest cylinder size smaller than this size and then make up the difference with tip extenders. Therefore the implant total (cyliner plus extender will be within 1/2 cm of the size of the corpus.

The problem of a long flacid state is one of the problems of an implant. Prepare to have a locker room conversation piece.

Most of my life I had like a 3 1/2-4" flaccid with close to 7" most of my life. It basically almost double during erection. I guess if I understand correctly, I will have approx 18% less than the erect state with AMS 700 unit? This will be a huge difference from my past. I may be at 5" flacid now and hopefully 6" erect. I really dont know as I am partially inflated after op. I understand I only recieved a few pumps. Not sure how much more it will grow but I am at 5" partial erection. I guess I will look somewhat impressive flaccid lol.

I must say I've never had a conversation about pecker size with anyone in a locker room. Just sayin'.

most people think they are partially inflated during healing, I know I did, but in my case I was just inflated enough to keep the cylinder barely round. About you flacid lenght, yes you will be longer, exactly how much who knows but I would guess you estimates should be in the ball park. The good thing is with the ams 700 is that afteryou squeeze a little extra fluid out of the cylinders rather than an "auto" delate you will be very flacid and will hang almost straight down if you want to. But flacid lenght your implants will be about what it is now flacid but may appear a little longer when the pubic swelling completly goes away. However, all said, it will be what it will be and I think you will be pleased with all the aspects of you "new look".

Here are some good videos to show that show different men with implants being pumped and deflated. They are the ones at the bottom of the web page. There is some other good info on this page as well.

I may be at 5" flacid now and hopefully 6" erect.

Matthew,
If you are 5" now that means that in the best case scenario with the full expansion you'll get about 5.9" which is 1.1" shorter than you used to have. Did you happen to ask your surgeon what was the reason you couldn't get the cylinders long enough to have an end result comparable with your pre-op 7"?
The thing is that I am the same size - about 7" fully erected while flaccid is barely 4". And if the implant is going to cause me 2" of shortage I would rather not to go for it and instead continue using constriction rings, even though I hate it due to the numbness....
