A penis pump, also known as a vacuum erection device, helps men with erectile dysfunction (ED) achieve and maintain an erection. It works by creating a gentle vacuum that draws blood into the penis, improving firmness and sexual performance.

While it doesn’t permanently enlarge the penis, it effectively supports natural blood flow and can be used alone or with ED medications like Viagra or Cialis. For best results, use it with an ED ring (cock ring) to help maintain the erection.
