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.
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 people 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 people consider this a major problem, and it may make penetration difficult.
A prescription is not needed to buy these devices. They are reusable and should be cleaned after each use.
Why It Is Done
Most people who have erection problems can use vacuum devices, including those who can't take sildenafil or other medicines.
How Well It Works
A vacuum erection device usually produces an erection. The erection goes away when the tight band is removed. Many people who use a vacuum device say that they are able to get an erection that is satisfactory for sexual intercourse.
The vacuum device is less popular than other methods used to create an erection.
The risk of side effects is low, and they are usually minor. Possible problems may include:
- Pain or discomfort.
- Numbness or loss of sensitivity.
- A sensation that the penis is cold.
- Pinching scrotal tissue in the device.
No significant side effects or complications have been reported.
