For an explanation of baryon asymmetry an extra source of CP violation is required.I will review Two-Higgs-Doublet extensions of the Standard Model whichoffer simplest scenario for spontaneous or explicit braking of CP in a scalar sector. It turns outthat observation of the Standard-Model-like Higgs boson at the LHC severely constrainsthe models. It will be shown that the presence of CP violation requires the mostgeneral Two-Higgs-Doublet Model and therefore implies a possibility for large flavour changingneutral currents (FCNC).
