A body implantable penile prosthetic assembly offering a user a one touch to erection (OTTER) capability and a penile implant deflation capability is described. The assembly includes a pump and a release mechanism. The pump is connectable to a pressure reservoir and a penile implant. The pump is operable to pressurize liquid in the pressure reservoir and the pressure reservoir is operable to store the pressurized liquid at a first pressure between 20-50 PSIg that is configured to inflate the penile implant to an erect state. The release mechanism is connectable between the pressure reservoir and the penile implant. The release mechanism is operable to inflate the penile implant with one-touch input from the user where the release mechanism is configured to release the stored pressurized liquid from the pressure reservoir to inflate the penile implant at a second pressure between 10-20 PSIg.
