Typically the corpora are irretrievably damaged or removed. But not always. (This I infer at least one study I read that found a small number (vanishingly small) of men actually retain or regain some degree of erectile ability after implantation.)
Of course, some of that erectile ability might be the spongiosum, which SHOULD be insufficient for (coitus-ready) erections, but, who knows?
