The vacuum erection device (VED), a.k.a. penis pump, is one of the older treatments for ED. When the penis is placed in such a negative pressure environment, an influx of blood into the erectile chambers results in penile expansion and erection. The VED is an effective means of achieving erectile rigidity in men with diabetes, spinal cord injury or after prostatectomy. Additionally, it is useful in the post-prostatectomy period to maintain penile dimensions and tissue integrity. It is sometimes used for tissue expansion purposes prior to penile prosthesis implant surgery to facilitate the placement of the largest possible prosthesis.
TISSUE EXPANSION BENEFITS
Tissue expansion occurs in response to internal or external forces. The VED is a form of external tissue expansion that uses negative pressures to cause influx of blood into the erectile chambers and induce an erection. Furthermore, it results in increased tissue oxygenation, activation of tissue nutrient factors and mobilization of stem cells, all of which helps prevent tissue scarring and preserves/helps restore penile anatomy and function.
Side note: There are many non-medical grade sex toy penis pumps for sale on the Internet (as well as nipple and clitoris pumps) that all share the principle of using vacuum suction to cause influx of blood and tissue expansion.
VED HARDWARE
There are numerous VEDs on the market, which have in common a cylinder chamber with one end closed off, a vacuum pump and a constriction ring. The penis is inserted into the cylinder chamber and an erection is induced by a vacuum (either a hand pump or a battery-powered pump) that creates negative pressures and sucks blood into the erectile chambers. To maintain the erection after the vacuum is released, a constriction ring is applied to the base of the penis. The result is a rigid penis capable of penetrative intercourse.
These devices are also available through Private Gym.
VED PREP
The VED is prepared by placing a constriction ring over the open end of the cylinder. A water-soluble lubricant is applied to the base of the penis to achieve a tight seal when the penis is placed into the cylinder. The pump is engaged to generate negative pressures within the cylinder, which pulls blood into the penis, causing fullness and ultimately rigidity. Once full rigidity is achieved, the constriction ring is manipulated off the cylinder onto the base of the penis, the vacuum is released and the penis removed from the cylinder.
UP SIDE
The VED is beneficial insofar as it is a simple mechanical treatment that does not require pills or surgery. It can be used to enhance the speed and extent of sexual recovery after prostatectomy, minimize any decrease in penile length and girth that may occur, and enable achievement of a rigid erection suitable for sexual intercourse. Clinical studies have clearly demonstrated that VED use after prostatectomy helps preserve penile dimensions.
DOWN SIDE
Disadvantages are the unwieldy nature of the preparation process and the need for preparation time, which impairs spontaneity. Another disadvantage is the need for applying vacuum forces to the penis, which can be uncomfortable as the penis expands and inflates. The application of the constriction ring will mechanically impair ejaculation and can cause penile “hinging.” Other possible side effects are discomfort, pain, coolness, numbness, altered sensation, engorgement of the penile head and bruising. The constriction ring should never be left on for more than 30 minutes. After sex is completed, the constriction ring must be removed. Despite disadvantages, the VED can be a useful tool for men not interested in pills or surgery and particularly helpful in the penile rehabilitation process following prostatectomy.
