In the conventional left-right gauge model, if the Higgs scalar sector consists only of an SU(2)L doublet and an SU(2)R doublet, fermion masses are zero at tree level. There have been many studies on how they would become massive. With the help of a dark sector with U(1)D gauge symmetry, it is shown how all standard-model fermions may acquire realistic masses radiatively, including that of the top quark. In this context, the particle content of the model also implies the automatic conservation of baryon number B and lepton number L as in the standard model. Observable anomalous Higgs couplings are predicted.
