How does cycling increase length?

[PowerliftingDad]

So I am day 12 post revision.
Bruising is almost all gone but there is still some scrotal swelling.
I am thanfully getting natural engorgement but have not yet begun cycling.
I can see that my natural erection / engorgement is approximately an 1" shorter after my revision. Down from 6.5" to 5.5".
I am optimistic I will get that back after I begin cycling.
My question is...
how does cycling actually increase length??
Does the actual implant increase in length as it gets "broke in" allowing you to pump more?
Does your penis just increase in size allowing the implant to pump more?
Or is it something else?

I am not at all medical— this is what I’ve read on FT plus my own personal experience. Cycling softens the tissues on the shaft allowing them to expand. It also softens the tubes allowing them to also expand. I would add that to enhance this lengthening process is to add the Perito exercise.

I’m sure others may have a more educated view or differing personal experience.

Best wishes for the revision amigo. Following this thread. I’m cycling daily now at 8 weeks postop. (started at 6 weeks). Been wondering this myself. I notice that it seems i can hold an increasingly harder pump each day. I’ll pump up to the previous threshold each day. Hold that for :30-:45, then Perito exercise + couple more pumps. White knuckles for 3-5 minutes as i stretch to a new limit.

Everything’s getting harder for sure. The lengthening remains a mystery.

Good luck for sure! Hopefully you'll see cycling pay off soon!

I've been pedaling since January 31st, no stretch or invisible, a little girth yes, the most obvious thing I notice is the pain from the very aggressive cycling I do 60/70 minutes 2 times a day, now I've decided to do 25/30 minutes maximum 2 times a day as my doctor said, perhaps between healing and the aggressiveness of cycling is the reason for the pain that does not go away completely, it may be that I'm still inflamed, it's just my thought

Figured there's been enough studies recommending and confirming that aggressive cycling and VED use is effective for getting your size back/gaining more, that surely some of those experts also explain why it works.

First that came to mind was this one. It is about the Titan specifically but I think the reasoning applies to all implants. Basically stuff I don't understand about tissue expansion of corpora cavernosas and other things I don't get. I read through it and found these parts that I think count as explanations. First, here's their routine:

Following the instructional visit at 6 weeks, the patients were instructed to daily inflate to the point of discomfort for a short period of time. At the 6-month visit, the subjects were instructed to inflate their IPP as hard as they could tolerate every day for the next 6–12 months for at least 1 hour and not to exceed 2 hours per day (Henry et al., 2015, p. 1300-1301).

Reasons it can work:

There was a statistically significant reduction in the amount of pumps to full inflation at 6 weeks postimplantation as compared with immediately postoperation. However, at 6 and 12 months, the amount of pumps needed statistically increased from postoperative measurements, suggesting there are more volume in the cylinders, which could represent an increase in penile measurement resulting from using the daily maximum inflation protocol (Table 5 and Figure 2) (Henry et al., 2015, p. 1301).

Tissue expansion stuff:

In addition, the participants were instructed to daily inflate their prostheses for the first 4.5 months after the first instructional post- operative visit and then to maximum inflate the implants for the next 6 months leaving it inflated for at least 1 hour per day. Utilization of a postoperative IPP penile rehab consisting of daily maximum inflation may help create optimal tissue expansion of the corpora cavernosa in terms of resulting penile length and girth measurements (Henry et al., 2015, p. 1302).

The prolonged and daily usage of inflatable penile prostheses may cause the cylinders to act as tissue expanders. Tissue expansion has been well documented in plastic surgery and breast reconstruction literature [15,16] (Henry et al., 2015, p. 1303).

How tissue expansion works, as well as how VED use will also help:

This appears be attributed to the protocol of maximum inflation for at least 1 hour daily. Tissue expansion involves making the tunica albuginea more compliant so it will stretch and allow larger distention by the inflated cylinder. Experience with repetitive vacuum device application shows the tunica will respond with short exposures to the vacuum therapy. Sellers et al. showed that 10 minutes a day of vacuum device application twice a day for 7 weeks promoted visible penile lengthening in the vacuum cylinder when marked weekly in first-time implant patients. It also, and more importantly, allowed the implanting physician to upsize his cylinder approximately 3 cm when compared with the average implant without vacuum preparation [21]. The application of vacuum to a penis with corporal fibrosis has also been described to preserve length preventing some of the shrinkage that accompanies removal of an IPP for infection. The published literature is, at best, anecdotal, but the belief is widespread among frequent implanters. The pressure difference between a hydraulic pump push inside the penis compared with low pneumatic suction on the external penis should be more than a thousand-fold stronger (Henry et al., 2015, p. 1303).

^Ignore it saying the published literature is anecdotal. Might've been true in 2015 when this study was performed, but it's no longer true in 2023.

I just referred to this in a new comment I left, and it makes me want to bump this because I think it could be good conversation, but I tend to kill those sometimes, I think.

First I've felt like explaining several things about me: if you think that me giving proper sources with citations and everything makes me look smart and professional, I can assure you I am NOT that smart. All I am is a guy who did get a masters degree, but that was after my brain injury, so mostly I just learned how to improve my writing and also I bet many of you haven't written papers for school in a very long time. I discovered that nowadays there's always free programs like Zotero to easily save and cite sources, so all I have to do is like type a number to cite something.

One thing I do have a lot of experience and "skill" at is doing research. I say experience because I was one of those speech and debate nerds in high school obsessed with policy debate. And I say "skill" because all that means is I have access to databases in a school's library and I can type in search terms like, "penile implants" AND "vacuum erection device" OR "VED." Then, I read the results it gives. Not exactly a "skill," as I hope you can understand.

Anyway, about this post, I think PowerliftingDad got half the answer right, and crazyjoe got the second half.

Powerlifter is right because consistent exercise with the implant does help it get "broke in" allowing you to pump more. And Joe answered the rest by saying,

Cycling softens the tissues on the shaft allowing them to expand. It also softens the tubes allowing them to also expand. I would add that to enhance this lengthening process is to add the Perito exercise.

What's interesting is I think OP and Joe pretty much explained what the sources say, but the study gives way more details. And that's another thing, some don't give full credit to studies, but I think people should believe this literature is from real, reputable and trustworthy authorities who perform these studies for the purpose of improving medical treatment all around the world. Peer-reviewed medical research is not the same as stuff you find on google.

These are real doctors performing real acts of medicine and releasing their findings properly using the scientific method. If anyone didn't know these are real urologists...

The above study first cites Henry, G. D. This is him and his background:


Next is Carrion, R. This is him and his background:


Next I can't find a ton of information about Jennermann, C, but I found that it is Coline Jennermann who is an MS of Regional Urology at Shreveport, LA.



And this is the last one, Run Wang and his background:


I've read also that some people don't fully trust studies because some were funded by Boston Scientific or Coloplast, but I really don't think that takes away any credibility whatsoever. These are real medical findings. There's no way to fake them or alter them, at least not without losing your medical license. This study and many other report real findings of dick sizes before VED treatment and before implant. Then these doctors find real numbers after controlled exercises that work to increase size. It doesn't matter who paid for it, because how the numbers did change is all that matters. And then doctors write about why this works, and why we should believe that it's been proved effective time after time.

implantologists are at least 50% advanced in age, I'd like to see only 1 implanted

Mine is expanding in length. Don't now why, but maybe because of aggressive cycling and using the VED a few times a week. This morning when I put the ruler to it bone pressed, it measured 7 1/2 inches in length and around 6 1/4 inches of girth at the base and 6 inches midshaft. I was never this big before. I'm going to continue this routine for a while.
64 yrs old. Started using Viagra mid-forties, Pre op length 6.5 to 7 inches, girth 6 inches at base and 5.5 mid shaft. Post op length 7 1/4 inches, lost a little girth. Married 38 years to an awesome wife. Implanted on 8/4/2022 Titan 24cm XL. Dr Hakky

I’m cycled religiously with the first implant
Rarely cycle the new implant
Zero difference
