What is a vacuum constriction device or erectile dysfunction pumps?

A vacuum constriction device (VCD) is an external pump with a band on it that a man with erectile dysfunction can use to get and maintain an erection.

The VCD consists of an acrylic cylinder with a pump that may be attached directly to the end of the penis. A constriction ring or band is placed on the cylinder at the other end, which is applied to the body. The cylinder and pump are used to create a vacuum to help the penis become erect; the band or constriction ring is used to help maintain the erection.

How Does It Work?

Generally most of the pumps follow the same procedure. It is:

• Place the pump, which can be pumped by hand or run on batteries, over your penis
• Pump the air out of the cylinder so that a vacuum is created. The vacuum draws blood into the shaft of the penis and causes it to swell and become erect.
• Once the penis is erect, with the help of lubricant, slide the retaining band down onto the lower end of the penis.
• Remove the pump

Intercourse can be attempted with the constriction band in place to help maintain the erection. The band can be left on safely for up to 30 minutes to allow for successful intercourse.

Who Should Consider Using a Vacuum Constriction Device?

Vacuum constriction devices are safe and can be used by patients with ED caused by many conditions. They could also include people suffering with:

• Poor blood flow to the penis
• Diabetes
• Surgery for prostate or colon cancer
• Psychological issues such as anxiety or depression

Vacuum constriction devices should not be used by men who may have a significant congenital bleeding disorder or a disorder that predisposes them to a condition called priapism.

What Are the Side Effects?

Being an unnatural approach, there are possibilities of side effects. The penis tends to be purplish in color and can be cold or numb. Other side effects can include:

• A black and blue mark or small area of bleeding on the shaft of the penis. This is usually painless and generally will resolve in a few days
• Decrease in the force of the ejaculation. The semen will usually dribble out once the constriction band is removed. Generally, this does not interfere with the pleasure of a climax or orgasm
