Following the procedure in the Glashow-Weinberg-Salam (GWS) model for electroweak interaction, by using two doublets and one induced bidoublet Higgs fields as a result of the interactions of the two doublets, we evaluate the predictive power of the left-right symmetry model based on S(2)_Lx
SU(2)_R x U(1) gauge group to the gauge bosons masses, leptons masses, and the structure of electroweak interactions. Both bidoublet and doublet Higgs fields have the contribution to the gauge boson masses after symmetry breaking. Meanwhile, leptons masses arise only from the bidoublet Higgs field. The parity violation could be associated with the mixing of the charged gauge boson masses from the induced bidoublet Higgs
