A mechanical penile prosthesis designed to be surgically implanted in the penis for the treatment of erectile impotence or as a functional component of a penile replacement prosthesis. The penile prosthesis comprises a pre-stretched, flexible, elastic, tubular component or sheath closed at each end thereof, and a plurality of cylindrically shaped segments or links, each having one or more convex ends and/or a concave end, enclosed within the tubular component. The pre-stretched tubular sheath maintains the segments in reference to one another, i.e. link-to-link contact, so that on straightening of the normally curved tubular enclosure a concave end of a segment mates with a convex end of an adjacent segment whereby the segments are aligned into a straight rod configuration resulting in an erect penis.
