Impotence or erectile dysfunction is considered the inability to gain or keep an erection for a period of time. Impotence or Erectile dysfunction affects 20% of men under the age of 50 and more than 50% of men aged over 50. It is considered normal for up to 20% of all sexual encounters to have some signs of Impotence, as many men will experience at least a few of the symptoms at one point or another. However, Impotence or Erectile dysfunction is not considered normal for any length of time for a man of any age; it is not a normal part of the aging process.

Impotence has many treatments that are invasive including penile implants, injections and suppositories that doctors recommend in some cases. The type of treatment offered by a physician will take into consideration the length of Impotence as well as overall health and medical history. Impotence is most commonly treated with penis pumps or ED pumps. ED pumps or Penis pumps are devices made of a plastic tube, a pump and constriction rings. The penis is placed inside the rings and then into the tube. The Penis pumps or ED pumps are then engaged so that the air is removed from the tube. Impotence can be caused by blood vessels staying constricted so that blood cannot enter the penis for an erection, while in other cases the vessels do not constrict, thereby not trapping the blood in the penis for engorging to happen. The pumps cause the blood to rush to the penis as a normal erection would cause, and traps the blood there so that an erection can be achieved.

There are many men that use pumps as a means of adding girth and length to their penis and do not have ED. Therefore this is not simply a treatment for some, but a recreational adult toy as well.
