penis pump is a cylinder that is fitted over the penis, with a manual or motorized pump to create suction. The apparatus creates a partial vacuum around the penis, engorging it as blood is drawn in. As vacuum increases, the difference between the inner blood pressure and the pump pressure increases as well.

A Penis pumps can be used to temporarily overcome symptoms of impotence, but do not cure the condition: a ring must be applied to maintain the erection which will otherwise immediately subside. Pumps may work even if there is nerve or vascular damage preventing a natural erection.

flexible compression ring (or sometimes more than one), commonly called cock rings when used recreationally, must be used. It is fitted on the open end of the cylinder, then an erection is created by pumping. Then the ring is pushed by hand onto the base of the erect penis before releasing the vacuum. This restricts blood flow out of the now erect penis, enabling the erection to be held even in the presence of problems of the vascular or nervous system which would otherwise lead to immediate loss of erection. In the best circumstances erections can be maintained for a considerable time, but manufacturers’ literature recommends that, for safety, rings should be removed after no more than 30 minutes. Very prolonged use (hours) will cause permanent harm.
