The aim of the thesis is to study models of the electroweak symmetry breaking caused by dynamically generated masses of quarks and leptons. (1) We perform the basic analysis whether the main underlying idea, that the masses of only known fermions can provide the electroweak symmetry breaking, is actually feasible. For that we elaborate a two-composite-Higgs-doublet model of the top-quark and neutrino condensation. The model suggests rather large number, O(100), of right-handed neutrinos. (2) We analyze the model of strong Yukawa dynamics where the dynamical fermion mass generation is provided by exchanges of new elementary massive complex doublet scalar fields. We focus on solving the coupled Schwinger--Dyson equations for fermion and scalar self-energies by means of approximative methods. We document that strongly hierarchical mass spectra can be reproduced. (3) We elaborate the flavor gauge model where the dynamical fermion mass generation is provided by asymptotically free non-Abelian self-breaking flavor gauge dynamics. We show that the Majorana type condensation of right-handed neutrinos in the flavor sextet representation triggers the complete flavor symmetry breaking. It leads to huge right-handed neutrino Majorana masses.
