Abstract: A thermally regulated penile prosthetic system includes a prosthetic capsule extending longitudinally from a base to define a shaft region terminating at a tip region. The prosthetic capsule includes an inner capsule portion nested within an outer capsule portion and a fluid cushion captured therebetween. The inner capsule portion defines an inner bore extending from the base region longitudinally through the shaft region, the inner capsule portion being supported with respect to the outer capsule portion at the tip region by a stabilizing member. A heating source is coupled to transfer heat to the prosthetic capsule; and, an outer skin layer extends substantially about at least a portion of the shaft region of the prosthetic capsule. The outer skin layer is configured to emulate penile shaft skin.
