Understanding the Penis Pump

A Vacuum Erection Device (VED), often called a penis pump, is a non-invasive tool used to treat erectile dysfunction (ED) and support penile rehabilitation. It works by creating a vacuum around the penis, which draws blood into it to create an erection.

Why Use a VED?

  • Erectile Dysfunction Treatment: A VED can help you achieve an erection firm enough for sexual activity. When used with a tension band placed at the base of the penis, it can help maintain the erection.
  • Penile Rehabilitation: Regular use, especially after prostate cancer treatment, can promote healthy blood flow, which may help reduce penile shrinkage and keep the tissue healthy.

Important Considerations:

  • Some users report that the erection feels different or colder than a natural erection, and there can be a “hinge effect” at the base.
  • VEDs are not suitable for all men, especially those with a history of priapism, certain blood disorders, or those taking blood thinners. Always use a VED under medical guidance.
