A penile prosthesis includes at least one and preferably a pair of penile implants. The penile implant is a flexible, elongated member having a short proximal stem which is hollow and includes a fluid filled reservoir. The stem is adapted to be implanted into the root end of the corpus cavernosum to support the implant. The flexible member also includes an elongated flexible, non-distensible distal portion having a chamber substantially filled with a non-compressible fluid and a conical tip and an intermediate fluid filled pressure bulb pump which includes a valve mechanism. The valve mechanism allows fluid to be pumped from the reservoir in the stem into the non-distensible chamber to pressurize it and make it rigid. The implant includes a pressure relief valve which allows fluid to be transferred back to the reservoir.
