What is a Vacuum Constriction Device (VCD) & How Does It Work?

What is a Vacuum Constriction Device (VCD) & How Does It Work?

For many men, vacuum constriction devices or vacuum pumps are a first-line solution to help with erectile issues. They’re easy to use, and also avoid potential drug interactions and serious side effects from medications.

Essentially, a vacuum constriction device or VCD is an external pump that can help men maintain an erection. The pump helps the penis to become erect, and a band attached to the pump helps to maintain the erection. The VCD consists of an acrylic cylinder with a pump and a constriction ring or band, which is placed on the cylinder at the other end. The cylinder and pump are used to create a vacuum to help the penis become erect, and the band or constriction ring is used to help maintain the erection.

How do VCDs work?

Essentially, VCDs work by creating a vacuum around the penis. The vacuum helps blood flow into the penis, producing an erection-like state, while a constrictive band is placed around the base of the penis to maintain the erection. The process is completely scientific, and repeated use has shown to result in longer-lasting erections over time.

While VCDs and vacuum pumps like VaxAid aren’t a cure for the conditions that prevent you gaining or maintaining an erection, they can be an effective way to restore your sexual ability. Scientific studies estimate that 90% of those with certain conditions are able to regain sexual function by using an ED vacuum pump like VaxAid. We've designed VaxAid to be far more convenient and powerful than other ED pumps, giving you the best option available.

Unlike other ED pumps, VaxAid doesn't require lubrication - it's designed to be used in the shower or bath for a more discreet, comfortable and effective experience.

Who should consider using a VCD?

Vacuum constriction devices are most commonly used to treat medical causes of ED. These causes include:

  • Poor blood flow into the penis
  • Excess blood flow out of the penis during erection
  • Damage to nerves that control the erection reflex
  • Because VCDs are safe to use and have few long-term side effects, they are also sometimes recommended as a treatment for anxiety-based ED

Because there are dozens of issues that can potentially cause ED, including a number of potential physical and mental health problems such as cardiovascular issues, stress, depression, anxiety, sleep apnea, low testosterone levels, and more, it’s important to work with your healthcare provider to first determine the cause of your symptoms.

Once you have done so, helping your physical symptoms through penile exercises and vacuum pumps can help. To learn more about Vaxaid’s unique hydro pump options, visit our shop or our FAQ section.
