An implantable penile prosthetic insert for placement in a corpora cavernosum of a penis and capable of transitioning the penis between a flaccid and an erect state. A body of the insert is made from a bio-compatible material and extends between a proximal end and a distal end. The body includes an exterior surface defining a channel extending longitudinally along the body. The body is configured to transition between a first state corresponding to the flaccid state of the penis and a second state corresponding to the erect state of the penis. The channel is present in both the first and the second state. A method for implanting a penile prosthetic insert and a kit of parts are also disclosed.
