Erectile Dysfunction: Vacuum Constriction Devices
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.
The pump helps the penis become erect while the band maintains the
erection.
How does it work?
To use the device:
- Place the pump, which can be pumped by hand or run on batteries, over the 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 after releasing the vacuum.
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.
How well do vacuum constriction devices work?
Studies suggest that about 50%-80% of men are satisfied with the results of
VCD. As with any other method of treatment for erectile dysfunction (ED),
satisfaction rates may decrease with time.
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, including:
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 (a prolonged, sometime painful erection lasting
over several hours). Examples include sickle cell anemia, some forms of
leukemia, and other blood conditions.
What are the side effects?
An erection obtained by the vacuum constriction device is not the same as an
erection achieved naturally. 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 bruising 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 constriction band traps the
ejaculate or semen at the time of orgasm. This is not dangerous and usually
does not cause pain. 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.
