Making the case for the benefits of sleeve pumping - Theory
Brothers, I’ve been kicking around a theory regarding the use of sleeves while pumping and wondering if anyone could offer any medical perspective to see if my thoughts on the matter hold any water. Its been debated that the negative pressure of a pump works mostly on the subcutaneous veins and tissue exterior to the CC, leaving very little impact on the tunica and CC themselves.
To quote another member here “At maximum erection with a very rock hard tunica, pumping at pressures not exceeding medically recommended levels (200 - 250 mmHg, 270 - 340 cmH2O, 7.9 - 9.8 inHg) would have minimal effect [on CC expansion.] You will not be able to elevate the tunica to increase blood volume in the cavernosa as the pressure will still be above arterial pressure (unless you’ve got untreated very high blood pressure). I see pumping only effect at this degree of erections to be on the tissue under the skin and over the tunica (subcutaneous tissue) filled with very loose connective tissue.”
If I’m understanding correctly, the member seems to propose that entering the tube with an erection may infact be counter productive due to the arterial blood flow of the subcutaneous tissue being higher than that of the CC, thus preventing additional blood volume from entering the CC adequately enough to cause the needed tunica distension to realize gains. So in effect, based on this reasoning, it would seem going in flaccid may have a more positive effect on tunica distension which is counter to what I see recommended around here quite often, going in with a full erection.
My theory based around this concept would be to use a tightly fitting silicone compression sleeve like the medium hardness Silisleeve from MOS, one that will still stretch in the tube but maybe a little too tight to use outside the tube, as this would create a positive pressure on the subcutaneous blood volume forcing more blood to enter the CC. So while it may seem counter-intuitive to use compression on a girth exercise, if it causes more blood to divert to the CC where we are looking for maximal expansion to take place, which is what makes the case for clamping, there could be some benefit. It has also been my experience that I have gained more girth at my base where I have used more compression, like a cockring, despite doing jelqs which force blood up the shaft and start with compression at the base. I’m not sure if that is a common experience though but I have seen others that have made this observation also. If that is the case, this compression theory could potentially be the reason why. I am no biology major, so I may be totally off base, which is why I’m asking if there are any members with a medical background that could add credence to the theory.
