A Vacuum Erection Device (VED) uses negative pressure to draw blood into the penis. With a constriction ring, it can be used for intercourse. Without a ring, short daily sessions are sometimes recommended to oxygenate penile tissue and help maintain length and elasticity. This practice can support erectile health in men who experience reduced nocturnal erections - whether due to ageing, chronic conditions, prostate surgery recovery, or Peyronie’s disease.
