Vacuum Erection Device

What are vacuum erection devices?

The flow of blood into the penis is increased mechanically via a vacuum erection device or pump. An external penile pump (either manual or battery-operated) creates vacuum suction within the cylinder, pushing blood into the penis to create an erection. The base of the penis is then wrapped in a stretchable tension band to keep the erection for long enough to have sex (up to 30 minutes).

How do they function?

VEDs operate by placing your penis in a plastic cylinder, which is then pumped to remove the air. This creates a vacuum inside the cylinder, causing the penis to fill with blood and induce an erection. Then you slide a constriction ring around the base of your penis to keep the blood from leaving and your erection in tact.

What is the duration of their effectiveness?

Using a vacuum device, you can have a complete erection in a matter of minutes. You can release the vacuum and remove the cylinder after your penis is erect and the constriction ring is in position on the penis. The constriction ring prevents blood from escaping from the penis, ensuring that your erection is maintained. After that, you can engage in sexual activity. The constriction ring should not be left on your penis for more than 30 minutes because it can cause injury.

Are there any unfavorable effects?

Yes, but they’re minor issues. You may observe discoloration or bruising of your penis on a regular basis. Some patients remark that their penis feels “cold,” and that their erection lacks the stability of a normal erection, but this is rarely a problem.

The constricting ring may be a little unpleasant for you. It also stops the flow of sperm during the orgasm (climax), which can be unpleasant. This is harmless because the semen returns to your bladder and is passed out with your urine when you next empty your bladder.

Most men who use VEDs believe them to be a safe and effective way to get an erection, with few adverse effects and decent outcomes after some practice.

ED is a little embarrassing to talk about, but I want you to know your situation can change.
