What is the difference between using a PeniStretcher and a vacuum pump?
A vacuum pump serves exclusively as an erection tool. Due to the negative pressure which the pump generates, the blood vessels are immediately and abruptly dilated. However, these results are temporary. Unlike application of the PeniStretcher, this method has no effects on the penis suspension tendon. The part of the spongy body which is hidden in the peritoneal cavity is also not affected by the vacuum pump.
