How Does a Penile Vacuum Pump Work?
A penile vacuum pump, also referred to as a vacuum erection device (VED), works by applying gentle negative pressure around the penis. This action draws blood into the erectile tissue and supports temporary straightening and expansion of the shaft. For men with Peyronie’s disease, the process may also help reduce rigidity in scarred areas over time.
Here’s how the treatment is typically performed:
- Placement of the Cylinder – The penis is inserted into a clear plastic tube, forming a seal around the base.
- Controlled Vacuum Pressure – Air is removed from the chamber via a hand-operated or motorised pump, which encourages blood to flow into the penis.
- Stabilising with a Tension Ring – Once erect, a rubber ring is positioned at the base to help sustain the erection by restricting venous outflow.
This approach is non-invasive and typically painless. The device is used under guidance, with erections maintained for a limited period, usually up to 30 minutes.
