A type of device to improve male sexual potency; a penis protecting pad made of flexible material; on the upper edge of the penis protecting pad are two adjusting pads, and on its lower edges are left and right adjusting belts respectively pulled through the slots on the waist band. On the lower part of the penis protecting pad is a threaded tube joint to accommodate an inside threaded tube body. One end of the tube body is jointed and adhered to a flexible glans penis to form a penis-shaped structure to be worn onto a real penis.

A device for affecting or enhancing erection of the penis comprises an external inflatable cuff which encircles the shaft of the penis at its base and extends distally. The cuff is provided with a plurality of volume expandable annular spaces arranged parallel to one another. The spaces are filled with fluid under pressure from a squeeze bulb to affect a tourniquet action. The spaces are inflated sequentially in a proximal to distal direction. As the spaces become sequentially pressurized, the inner diameter of the cuff is reduced, constricting the penis and trapping blood within the shaft and forcing it distally to thereby increase the rigidity of the penis.

A method for treating Peyronie's disease includes providing an elongated tube having an inner diameter that is substantially equal to the outer diameter of an erect penis, such that the walls thereof will be adjacent the outer surface of the erect penis. A base portion is provided on the end of the elongated tube that is operable to be disposed about the base portion of an adult male penis to provide a seal therewith to air flow. The adult male penis is inserted into the end of the tube having the base portion associated therewith and the base portion moved downward against the base of the penis. A high air flow vacuum source is disposed and connected to the opposite end of the tube, such that a negative pressure is formed therein. The negative pressure results in the penis moving from a flaccid condition to an erect condition. After the penis has become erect, the seal between the base portion and the base of the penis is broken and made numerous times to create a turbulent air flow upward along the inner sides of the tube between the interior of the inner sides of the tube and the outer surface of the penis. This turbulent flow creates a significant amount of agitation within the tissue of the corpus cavernosum of the penis, as the tube is moved from side-to-side and in all directions.

A penis erection assisting device contains a sealing member for sealingly accommodating a penis therein, the sealing member having an opening at one end thereof to insert the penis, an extracting hose connected to the sealing member and a pump for extracting air within the sealing member, an expandable circular bag member provided at the opening of the sealing member, and an exhaling hose for supplying air extracted by the pump into the circular bag member to expand the circular bag member.
