Two questions regarding cycling and the supposed gains that come with it:
1) How does cycling help you gain length? If the cylinders are pushed into the edge of your glans and let's say cycling gets you an extra 2cm length; will the tips no longer sit near your glans? Will they sit further down your shaft? I thought the cylinders were a fixed length so how do they actually grow longer if they are a fixed length?
2) Is there anyone here that has not gained any size from cycling?

An implant is not a penis enlargement (many of us wish it was!
All IPPs are made of some type of elastic material, whether they are a fixed length/girth or claim to expand. Your surgeon would have sized you to take into account your natural maximum dimensions as measured by him, and the type of implant you have. After surgery there is a lot of trauma to your body that can often cause your penis to lose size and look unnatural temporarily. Even a "fixed size" implant usually won't be fully expanded initially. With healing and regular cycling most guys seem to eventually get back their pre op length and girth, sometimes back to pre ED size. Some implants do claim expansion but that will only work if you stretch the tunica albuginea tissue inside the penis back to its original size, which is a fixed size in all of us. Cycling is usually the way to do that post surgery, but it can only stretch to the maximum size you ever were in your life, regardless of how large or elastic the implant cylinders are. And if the cylinders are oversized it can actually cause erosion. Hence the importance of "right-sizing" the implant. Over time with regular cycling my cylinder tips have become much deeper into the glans when I'm erect. They are now very far in, which helps greatly for PIV sexual performance as my glans is quite rigid even without further engorgement.

I'm taking this to mean restored original size. I haven't "gained size" but I have restored my pre ED size through a combination of things:
- Using a VED daily before surgery to reverse the effects of penile size loss/atrophy caused by ED.
- Using a VED daily before surgery to stretch the penile tissue and help allow implantation of the largest sized cylinders suitable for my anatomy.
- Making sure my surgeon fully understood my goal of size restoration, and jointly deciding on the best implant to achieve that.
- Cycling frequently post op (sometimes aggressively) to hopefully achieve the best outcome.

Re: Has Anyone Not Gained Length From Cycling?
As for where the "growth" comes from. IPP's do stretch some after surgery. This is well known to the drs. Also they can tell if there is any fibrosis in the penis. This is where a skilled dr becomes important. They size you to match what they measure & feel. Thus as you recover & cycle steadily. The cylinders should slightly stretch to your old erect length.
While it might seem like a simple surgery. There is a lot of skill involved in the sizing.

Re: Has Anyone Not Gained Length From Cycling?
As my doc explained it to me, the tunica of guys with ED is open atrophied from non-use, meaning it shrivels and loses some elasticity. When you regularly “exercise” your tunica, whether by getting natural erections, VED use, or pumping up an inflatable, the tunica regains some of that elasticity.
He explained that you can stretch a penis as far as it is going to go to evaluate how long it could theoretically get. That’s the point of the stretch test, and that’s how they measure you for your implant. But when you put the implant in, the tunica, unaccustomed to being stretched, simply doesn’t go that far. We often call the inflatable parts the “cylinders”, but they are much more like a balloon than a cylinder. And your tunica is sort of like a hose. If you inflate a balloon inside a hose, the balloon will only inflate to fill up the hose. If the hose is old and unaccustomed to being inflated fully, the internal pressure of the balloon can only do so much. But if the hose is flexible and pliable, the pressure from the balloon will push it further.
As for how it extends in length: the balloons can’t really extend in length, despite manufacturer claims. But that doesn’t mean they are getting fully inflated. They feel fully inflated because they are pushing against the hose, but they are not yet fully inflated because the hose is limiting them.
Over time with cycling (or simply use), that hose expands more, and so the balloons expand more too.
I didn’t spend a lot of time thinking about my length. But when I did measure, I wrote it down here. A few weeks after surgery I was at 4.75 inches. At the six month mark I was 6 inches. I didn’t think about “cycling” so much. I just inflated for (almost daily) masturbation and sex.

Ok interesting. So the cylinders actually do get longer? I had some very minor fibrosis distally on the left, hopefully that hasn't impacted my length.
I wonder how are the cylinders shorter now but when I pump them up they will somehow get longer. I can understand how they might get a little wider, but just can't understand how they might get longer. I always thought they had a fixed length.

1.25 inches in length gains in 6 months is insanely impressive!
Even after reading this I still don't really know how the length gain happens. You even said it yourself "the balloons can't extend in length." It's very hard to comprehend.
So assuming the tips of your balloons were in your glans when you were 4.75 inches 6 months ago. How could they still be in your glans now, are they now sitting further down your shaft, given that your glans is now 2.5cm further away from the base of your penis?

Also surely you'd have noticed your penis growing longer and longer over the past few months even if you weren't measuring.
Visually there is a massive difference in looking down at a small 4.75 inch penis to looking down at a normal sized 6 inch penis. You must have been amazed watching it grow so much as the weeks went by. I would love to see the same happening to my penis. You actually (re)gained 33% in length which is astounding!

the cylinders are installed uninflated , when you pump them up they push against the length and girth of the penis , with more expansion available if the penis expands in time to its previous ,original size
If you put them in a skinny, short tube ,they would only be able to fill that until stopped by the walls
if you put them in a small cotton sock . they would fully inflate until they reached their limit .
so your dick flexes ,stretches , the cylinders expand to meet the available space
and the tip stays in the same place (hopefully they do not get pushed out of the glans ) the cylinders expand when the penis does .

Irish Lad I don't think that sort of gain is too uncommon. You will find other guys on here with similar results but it takes time. My own experience has been very close to Leto's. I was less than 5 inches bones pressed erect post surgery. Disappointing but I had expected that initially from the research I'd done. I remained that size while left erect for 6 weeks waiting to begin cycling. Once I commenced cycling I started to see visual results within a couple of weeks, although I didn't measure at that point. That was an eye opener for me and very welcome progress! After 6 months post op I was close to 6 inches BPEL. Now at 8+ months I'm at 6.5 inches BPEL. I'm not really expecting further gains as I don't believe I was ever bigger than that, but I'm continuing to cycle frequently, as well as using my implant for sex and masturbation multiple times a week, just in case my memory is hazy.
Re the balloon thing, think of those really long balloons. They have a fixed length in that if you keep inflating they will eventually burst. An implant won't do that, it just won't inflate any further once it has stretched your tunica to its maximum. But balloons can also be inflated and deflated. I think of the implant as being similar but less elastic. Cycling helps stretch your tunica to hopefully regain any size lost through ED/atrophy and surgical trauma. So eventually it will allow the implant to inflate your tunica to the maximum possible. Leto explained it better but that's my 2 cents worth.
