Reservoir size

[Bigdave]

I'm a bit confused on my reservoir size.
My doctor says, and also noted in his operative notes, that he installed a 65cc reservoir, however, the AMS documentation I have with the model/serial # stickers notes a 100cc reservoir.

What would be the normal size reservoir for an AMS-700 LGX 21cm implant?
Is there any way to tell on an x-ray what capacity reservoir I actually have?
What do most LGX 21cm owners have for a reservoir?

I can inflate fully, and the pump still fills and gets very hard when at max inflation, so there doesn't seem to be a shortage of saline, but I'm still curious what exactly I have installed?

I think the 100cc refers to the capacity of the reservoir but your doctor filled it with 65cc because that was the amount necessary to fill your cylinders.

The Titan Coloplast has a max reservoir size of 125cc, but for example, there are different recommended fill amounts for each cylinder length according to this document: https://iu.coloplast.us/wp-content/uplo ... M00045.pdf. In my case, I have 22 cm cylinders and my doctor told me my reservoir was filled with 95cc, which is directly in line with the recommended fill range for this size.

I have a 125ml reservoir with 110ml saline.

Thanks guys.

I just looked over the AMS Operating Room manual, and it clearly lists the 21cm LGX needs a 100ml reservoir.

I can't imagine a doctor would install the wrong component with the system, and the AMS info I was provided clearly shows 100ml.
I may try to find the contact info of the AMS rep that was present and ask him.

The important thing is it seems to work correctly. It's just irritating to see an inconsistency in the records.

A problem with the present implant models is that they are not made for men with girthier penises, resulting in a considerable loss of girth when the implant is installed (e.g. my penis has a circumference of 7 inches, which will likely result in a loss of an inch or more after insertion of the Titan Coloplast).

I have no expertise in this field, but could "overfilling" the reservoirs (i.e. deliberately exceed the recommended fill volumes) be a potential solution to increase the circumference of the implanted penis for men with a (naturally) girthier penis, or are the present reservoirs to stiff to accomodate this?

I have a 21cm AMS 700 CX with conceal 100ml reservoir. My Dr said he filled it to max recommendation, all 100ml. He said he always fills to capacity because the cylinders will soften and stretch over time and it's better to have more fluid than needed, then to not have enough.

Not a simple answer. The material that the cylinders are made of have the potential of limited stretch. The implant companies say it differently but if you get down to the basic meanings. They mean almost the same thing. Yes, American English can be confusing.

Now it gets complicated. Titans are made of very ridgid material. Its ability to stretch either in diameter or length is limited. The stiffness is what makes it the preferred implant for peyronies.

AMS uses 2 different materials. The CX will stretch in the length a little but more in the diameter. The LGX will stretch in both length & diameter. But the AMS implants start at a slightly smaller diameter than the Titan. So in my opinion. The final diameter difference might be small. Also, the tunic tissue that surrounds the implant cylinders has a max amount of stretch in it.

Now lets get more to your question. Logically it would seem that more fluid could maybe result in more length and/or girth. Here is the problem. Think of a car tire. Its empty, as you inflate it more the tire does grow in size. But the belts limit the tires diameter & to an extent the tires girth. All this comes to a limit at some pressure point. Don't ask me what that point is. A popular quoted study shows some Titans & LGX tested to 20psi. Sorry I don't know the metric equivalent. Now here comes a reality check. My dr works closely with AMs, now called Boston Scientific due to a merger. He is even in some of the AMS YouTube videos. I asked him in person about those pressures used in the test. He told me, in person. That most men can only produce around 12psi with the AMS pump. He said that he was able to generate around 13psi. So the amount of stretching shown in that study are not a realistic achievement.

More confusion. I have seen members that have been able to get some very significant girth. But I do not remember a 7 incher. I have a similar problem reaching 6 inch girth. I think that I can get there but its going to be a lot of pumping on my part. I'm pumping so much & so agressive that my dick is tender the next day. About the time the tenderness goes away, its time to pump again.

I guess the easy answer is that implants do not cover all dick sizes very well. All you can do is cycle your implant every day & see what you get after 1 to 1 1/2 years. I have heard that Titans can be ordered in a custom size. Don't know if that is the truth. Not much help if you already have an implant.

I have the same size titan and don’t recall the reservoir capacity or the amount filled, but the surgeon told me she went 25cc beyond the recommended fill to level for the 26cm. She does this to accommodate for the stretch which happens over time. No downside to a bit of extra fluid in the tank.

They come in a kit. The 21 cm implant kit would definitely have a 100 cc reservoir in the kit.

That's what I would think as well. The sticker seems to confirm this.
