I assume that Dwight refers to sural nerve grafts, performed after the
erectile nerves are destroyed during surgery.

I recommend doing a Google search on "sural nerve grafts."

It appears from a cursory read that the graft is performed during the
prostatectomy, not after.

I would guess it' medically feasible, but it would require going back
inside that nest of internal scar tissue all over again and it doesn't
raise the odds of potence dramatically. The boost odds are statistically
well defined for no nerves/one side/both sides spared.

I.P.
