Effects on blood carries another concerns especially when using US within clamping as there are some studies indicating the possibility of lysis of erythrocytes in vivo.
Also there is possibility to cause “blood flow stasis” during standing ultrasound wave especially if there happens to be a reflector causing it.( And the skin to air boundary at the back of your penis is indeed such a reflector as well.)
3MHz ultrasound have been reported to cause blood cells grouping into bands during the stasis. Damages in endothelial linings of the vessels affected by the stasis could occur but mainly being reversible. Again like in many other possible damages no permanent damages has been found. 1 MHz lack references but we need to consider similar outcomes.
Heat accelerates both cellular oxygen consumption and the rate hemoglobin donates it. The oxygen consumption can be doubled at temperatures of 41 to 45 C.
Clamping sets should be shorter than usual and extra care should be taken not to get severe hypoxia.
The blood , plasma, is not going to warm very effectively with ultrasound, basically very poorly the blood keeps cooling the collagenous tissue quite a bit during the set.
There are the known risks. The relatively low protein content and the density of the organ in the inflated state also brings many obstacles on heating as well.
Waves are getting scattered with the blood cells and the heating effect by the absorption in tissues is lower because lot of the intensity is lost in the scattering.
Blood itself, the plasma, is not going to heat with US a much so the blood keeps cooling the collagenous tissue a lot.
The penis gets warmer but with a weaker rate than when flaccid.
This may lead the user be tempted in increasing the intensity which triggers even more unwanted non-thermal effects.
About the magnitude of risks. For the records it has to be stated as a one taken in to concideration. Risks are real and have been realized in clinical studies.
Does it stop me personally trying it is another thing.
Everyone worrying about it is better to leave alone, everyone else should study it before jumping in.
What is your take on cock ring ballooning with partial blood flow in the 80-110 % EQ range while being in a general temp state bigger than pre-workout size (ballooned up) ?
