A vacuum device, which is sometimes used to treat
erection problems (erectile dysfunction), is a tube
made of plastic that fits around the penis. You coat the base of the penis with
lubricant and insert the penis into the tube. Air is pumped out of the tube, which
creates a vacuum. The vacuum helps blood flow into the penis, producing an
erection-like state in about 5 minutes. A constrictive band is placed around the
base of the penis to maintain the erection, and the tube is removed.
To a healthy young man, erectile dysfunction (ED) may seem unthinkable. You can probably remember times (think back to high school) when you wished it wasn't so easy to get an erection.
But as you age -- and especially when you have diabetes -- you may notice some changes. Maybe it takes more coaxing to get erect than it used to. Sometimes it may take more direct stimulation of the penis, whereas merely a daydream or the suggestion of sex was once enough. Or perhaps your erections aren't quite as...
The constrictive band may be left in place for up to 30 minutes. If
you want the erection to last longer, you may remove the band for a few minutes
and then repeat the process.
Vacuum devices may block ejaculation. You can still have an orgasm but may
not ejaculate (release semen).
Some men say the erection is "wobbly" or has a "hinge-like" feeling,
since the tissues beneath the ring on the base of the penis don't get hard. A
small number of men consider this a major problem, and it may make penetration
A prescription is not needed to buy these devices. They are
reusable and should be cleaned after each use.
What To Expect After Treatment
The device usually produces an erection, which goes away when the
constrictive band is removed.
Why It Is Done
Most men who have erection problems from physical causes can use
vacuum devices. Men who have erection problems because of psychological causes
may also use these devices.
How Well It Works
Between 6 and 9 out of 10 men who use a vacuum device say that they are able to get an erection that is satisfactory for sexual intercourse.1
The vacuum device is less popular than other methods used for creating an erection. The number of men who are happy with the device ranges from 3 to 7 out of 10 men who use it.1
The risk of side effects is low, and they are usually minor.

What To Think About
Be sure to discuss using a vacuum device with your partner. It is
important that both of you have realistic expectations of what the device can
do. The vacuum device gives you an erection that may be suitable for sexual
intercourse but is not the same as a normal erection.
The device can be difficult to
learn to use, and about four tries are needed to learn to use it
Some men find the band around the base of the penis distracting or
irritating during sex.
