We study the effects of a fermion with Yukawa-type coupling upon the tunneling of the double-well anharmonic oscillator. These effects prove to be nondramatic, despite the zero-frequency bound-state eigenmode one would encounter if one applied the conventional boundary conditions to the path integral.
