There is some clinical literature emerging, as well anecdotal reports, that for some men cobbling together vacuum erection device utilization in conjunction with PDE5 inhibitor medication uptake is more advantageous than one or the other intervention alone. In fact, some men don’t require the constriction device to sustain tumescence following the pump use, suggesting that the smooth muscle tissue NO/cGMP messenger pathway may be activated better once the vacuum has functioned to facilitate erection, while the medication reduces the degradation of these essential messengers that relax the penis’ intravcavernosal tissue.
Does it make the penis strong? Can the VED be used for rehabilitation purposes apart from on-demand sexual activity? Evidently possibly, though not a cure for ED. But following trauma such as prostatectomy at some point in recovery your urologist may recommend it to aid return to penile function. Blood flow is a good thing.
If somebody has Peyronie’s they can also explore VED use with their health care provider.
