Girth theory: Pumping vs. clamping

My first, largest and safest girth gains were from pumping. Those gains came once I learned how essential going in the tube erect and constant heat are.

I’ve seen claims in this thread and others that suggest what I think are misapprehensions over what lymphatic fluid is, how it’s formed, and it’s relationship to blood.

Lymph is blood plasma, and it enters the lymphatic system from the circulatory system via the interstitial fluid that surrounds our cells. Here’s the route: Blood plasma exits our blood vessels through hydrostatic pressure; once outside the blood vessels, it becomes known as interstitial fluid and serves to bathe the cells in our tissues; lymphatic vessels then take up the interstitial fluid, at which point it becomes known as lymphatic fluid; the lymphatic vessels then return it to the bloodstream by way of the subclavian veins. Although the fluid changes names as it passes from one system to another, it is still nonetheless the same fluid: blood plasma.

When you pump, clamp, or jelq, you are not somehow sucking ‘lymph’ out of the lymphatic system. In fact, it’s the other way around: you’re increasing the hydrostatic pressure within the circulatory system, which forces a greater than normal amount of blood plasma out the blood vessels and into the interstitial space. The lymphatic system’s job is to transfer that fluid back out of the interstitial space. However, since it’s action operates at much lower pressures than the circulatory system and is not pumped by the heart, the fluid transfer out of the interstitial space lags behind that which you’re creating with your PE exercises. The result is fluid build-up. Given time, the lymphatic system eventually catches up and the fluid is drained, returning the interstitial fluid balance in your penis’ tissue to normal.

With regards to PE and gains, the critical point here is that the pressures in the interstitial space and in the lymphatic system remain much lower than the pressures within circulatory system. The claim that this fluid is at a greater pressure than that of corpi or blood vessels and that it somehow ‘pushes back’ against them, preventing or even reversing gains, is simply incorrect. The only reason the excess fluid is even present in the first place is due to the much higher pressures within the circulatory system.

Regardless what method you use, the flow of fluid is the same: blood vessels —> interstitial space —> lymphatic vessels. And in all cases you are expanding the vessels and bodies of the circulatory system and presumably creating permanent enlargement over time through a regular practice. If you’re going to call into question pumping on this count (I.e., the existence of fluid build-up), you may as well call into question PE as a whole.

Taking things from general human anatomy to my own individual level, I personally have seen real, permanent girth gains from clamping, jelqing, and pumping. However, I have also experienced real, permanent discoloration from clamping and jelqing, along with temporary bruising, skin irritation, uneven gains, and discomfort during the exercises. Therefore, I’ll take the pump, hands down. Additionally, though I don’t attach any significance to it for the reasons cited above, clamping and jelqing always resulted in a great deal more fluid build-up for me than pumping.

Very clearly explained Ferservadu.

It’s interesting how we are all different. I get no fluid build-up from jelqing, and only get it from clamping and pumping after a very long time in the clamp or pump. If I pump at fairly high pressure, I get very little fluid, whereas if I pump at lower pressure, I get more.

The number of people who get little or no permanent gains from pumping seems to be extremely low though.

I’m confused now a few weeks back you posted this when I asked you about pumping and clamping.

“I think my girth gains came from clamping. It seems to place more force on the tunica. It’s a more injury prone modality but certainly works.

The girth from pumping seemed to be more temporary and spongy. For lasting gains I’d use clamping”

So which is it ?

When someone says, “Pumping doesn’t work”, or “pumping only produces temporary gains”, they mean to say “Pumping doesn’t work for me”, “Pumping didn’t work for me”, “Pumping produced only temporary gains for me”. I have had great girth gains with my Bathmate. A half inch in a year. Someone private messaged me to make sure that was what I meant in my pumping log, and when I said yes they seemed like they couldn’t believe it. I even asked “Is that fast?”, cuz I had no idea it was. Pumping works for quite a few people, and pumping mixed with jelqs for even more. I have only barely ever messed with clamping, and plan to save it as a bit of a last resort if and when the Bathmate gains cease to come.

They are both true. Pumping does leave you spongy afterwards. If your looking to have sex after girth work go for the clamp. The biggest gains came from pumping, the best post workout gains came from clamping.

My greatest gains in girth and possibly length have come from my use of clamping or a cock collar to restrict blood flow and using ULIs to hyperextend the tunica.

This approach has resulted in relatively quick gains in both girth and length.

It comes at the price of major discoloration and capillary bleeding until your unit becomes immune to the extreme pressures.

I am currently attempting to restrict any future girth gains by using a 2.25 inch diameter tube and forcing all growth lengthwise.
The exercise definitely is stretching the ligaments, which I feel at both the base and neck of my cock following each session.

The problem that I am encountering is that I can find the time for the ULIs but very limited time for the pumping.

I will soon find out if I have once again exceeded my girth goals, I am currently 6.0+ glans, 7.0+ mid, and 8.0+ base, with 1/2+ inch increases during sessions.

I would much rather continue my exercises than sit back and wait for a more convenient time.

Whole-heartedly agree.

That does seem to be the case.

I should clarify that the point of my previous post was to stress that the origin of fluid, and the resulting pressure, is identical across all methods. I wasn’t trying to make a case that pumping is necessarily superior or results in quicker results. I’m just tired of hearing claims about lymph that I think are uninformed or illogical.

There’s no denying, however, that jelqing in particular subjects the tunica to more mechanical stress than pumping. It may be that guys who aren’t seeing gains with pumping haven’t been doing enough manual work to complement the pump. Personally, I never clamped or pumped without that additional work. Sadsak slinkies, bundled stretches, fulcrum stretches, whatever: I think limbering up the tunica is just as important as heating.

Sorry, I wrote it wrong: what I meant to say was : ‘The number of people who gets permanent gains from pumping is extremely low.’. That according to anecdotal evidence. Even on the tigerpumping forum you can read that permanent gains from pumping are not the norm but the exception.

Edit: I see you got what I meant neverthless. Nice.

Anyway, it’s me speculating the fluid accumulation constraints tunica expansion. I’m not that convinced by your explanation of why that can’t be the case, although I very much liked your post. Fluid is more easily expanded than tunica, so there isn’t much tunica expansion when pumping IMO. That’s why it is a failure. CS is also more easily expanded than tunica; so to have a good degree of expansion in the tunica, you have to make use of such high pressures that are dangerous for the urethra, at least from a theoretical point of view.

I have to say though that clamping gains are volatile as well, so probably there is not much tunica expansion when clamping either.

I’ve tried different lubes for pumping and at equal vacuum and duration I get less fluid build-up using silicone lube over water based lube.

Just an observation, for what it’s worth.

Very true. That’s why gains from pumping alone are very hard to attain. You have to couple it with a manual routine, like jelqing. I view pumping as an enhancer of what you are already doing. Just another piece of the PE puzzle, another tool in the arsenal.

So true. It multiplys everything else you do. It fills the pensi with blood to work with. Great tool.

I think to gain with pumping alone you have to do it everyday.

Yeah that’s how I tend to see it too.
