Nothing will change except his ability to fertilize a jill.  His scent,
behavior, and personality should stay exactly the same.  In general terms,
in a vasectomy, the tubes which lead from where sperm are produced to where
they leave the body are blocked or severed.  All the other glands and body
parts are completely intact; the vasectomized ferret functions normally, but
no sperm come out.
