Just curious if anyone after deflation find that your penis gradually starts slowly inflating again? Not inflated completely, but around 30%. Is there an issue with the valve not locking out or what? I can squeeze my penis again to deflate, but why don’t I stay completely deflated. I thought that once you deflate, then a valve locks, and no saline can flow back into the tubes. Anyone else ever encounter this issue? I was implanted about 9 months ago with a AMS 700 LGX. Other than this issue everything is great.

To deflate (after your slow re-inflation) do you need to press the deflate button?

I have long suspected that the instructions for locking the valve against auto-inflation are incorrect. I have determined that the instructions for operating the deflate function are wrong by careful experimentation on implant. I have run preliminary experiments on the lockout procedure and have not formed a firm conclusion yet, but indications are that the advice to give the inflation pump a squeeze to "lock" the valve is so much nonsense.

I leave the valve in the deflate position after deflating and do not have any problem at all with auto-inflation. If I follow the "squeeze the bulb after deflation to re-set the valve", I do get autoinflation. I plan to repeat the experiment, and if the results are consistent, I will report back.

I assumed this from day one. I have on numerous occasions, fallen asleep after pumping up and then waking up overnight realizing I was still inflated, so I press the deflate button and make an attempt to squeeze out the saline before falling asleep again.

What I have found though, is that upon waking up the next morning, I can continue to squeeze out saline from the cylinders *WITHOUT* pressing the deflate button again, and the check-valve in the pump squeals as the more saline is squeezed out.

The DEFLATE button activates a check-valve (on the AMS MS pump, at least). That's why the pump squeals as fluid is transferred back to the reservoir.

If you just deflate and do nothing else with the pump, you could auto inflate again if the reservoir gets squeezed. To stop auto inflate, make one quick press on the pump after you have deflated. You will hear a pop. The check valve is now set to the pump mode. The only way to get saline into the implant now is to squeeze the pump bulb. We all know that is not done automatically.

Thanks guys for all your excellent feedback. It’s greatly appreciated. Bailey

I've tried it both ways and still auto inflate to some degree either way. Makes no sense but I can live with it.
AMS CX, implanted Sept 2019.

Your right Frederickdave, I’ve also tried it various ways too, & I still auto inflate a small amount. Just enough that whenever I urinate I find myself squeezing to remove some of the saline. I guess if that’s all I have to deal with, I can live with it. Thanks

Bailey, if you're not having to press the deflate button again to push more saline out, and if you're getting the squeal or vibration from the pump when you do, you might be getting an incomplete deflation to begin with. At least in my case, my penis plumps back up to some degree between 10-60 minutes after deflating. On a few occasions, I felt like I might have auto-inflated but squeezing did not result in a buzz or squeal. Once or twice I may have had a partial deflation initially but since my cylinder's expansion area is all distally positioned, it's easy to know when there's no more saline in the cylinders.

If your cylinders have a proximal portion of the expansion area, you may have saline left in your cylinders when you've squeezed everything out of your penis. Some have suggested pressing on their perineum while deflating aids in getting out the last drop.

Waynetho, Thanks for the excellent information. When I deflate I do feel a vibration of saline returning to the reservoir for about 4 seconds like the AMS instructions say, but after awhile I notice that I am slightly inflated from my original deflation again. I just assumed that it was the pump & valve being pressed accidentally in the tight quarters of my clothing, & that’s causing me to inflate again. Unfortunately I have a very small scrotum, so my pump & valve don’t have much room & get squeezed I guess. The only other thing I feel from my pump is the valve slightly clicking open on my initial activation to inflate. I never hear or feel any saline moving in or out of the reservoir.

If the deflate button doesn't click again when you try to press it (after "plumping up"), do you still get some more buzzing when squeezing again? That's what I mean by under-deflation. If the deflate button is still engaged, but you can still make the pump squeal, it was probably still there from the last time you squeezed (unless you have a defective pump valve that leaks reservoir fluid into the cylinders).

I discovered shortly after activation that my plumping was unrelated to saline in the cylinders and came up with a theory that was later confirmed as plausible by a high-volume implanter, Dr. Allen Morey. My theory that he agreed with was that some of the still viable erectile tissues surrounding my cylinder were being compressed by the cylinders when I inflate, thus making them temporarily thinner. When I deflate, those tissues are still compressed down and as such my penis gets a flat "road-kill" look, minus the tread marks. Over the next 10 to 60 minutes the erectile tissues start to relax and expand back into the space and this plumps up my penis again. It's not my cylinders causing the plumping up but the natural tissues relaxing again after being compressed during inflation.

Maybe this compression/decompression is happening in your case as well.
