Will the corpus spongiosum still work after implant?

[KaBoom]

The cylinders replace the corpus cavernosum and thats the part the implant works its magic on.

However, the spongiosum, the tube that runs along the bottom side, is still the same same as before.

Its only been several months, but it does not seem to inflate at all anymore , giving a bit more of a narrow oval shape in the erectile state in my case.

Does it eventually get back to normal with cycling and time? or would one need to include a viagra to get it going too?
