We first heard of Bathmate ten years go. Bathmate hydro pumps are advertised to promote penile growth and help curb or even prevent symptoms of erectile dysfunction. This is also known as hydrotherapy. Bathmates work by using air and water to create  and maintain negative pressure (or vacuum) inside the tube chamber. This vacuum is created by the man pumping the unit towards his pelvis until there is a seal. This promotes an abundance of blood flow to the penis. Repeated use has been shown that Bathmates do help men with symptoms of E.D.

Many doctors are jumping on board of the Bathmate and are prescribing them to their male patients with positive results of sexual performance, stamina, and hardness being reported.
