Erection
Vacuum pumps – If medicines do not work, a vacuum pump can sometimes help. This device is made up of a plastic cylinder that fits over the penis, which is joined to a pump. The pump can be electrical or worked by hand. When the pump is used, it draws air out of the space around the penis. This causes more blood to flow into the penis, making an erection happen. Once the penis is erect, the device is taken off. To slow down the flow of blood out of the penis, a tight ring is worn around the base of the penis.
