The explicit form of the sixth order radiative corrections to the lepton L (L=e, μ, and τ) anomalous magnetic moment from QED Feynman diagrams with insertion of the fourth order polarization operators consisting of either two closed lepton loops or one lepton loop crossed by a photon line is discussed in detail. The approach is based on the consistent application of dispersion relations for vacuum polarization operators and the Mellin-Barnes transform for massive photon propagators. Explicit analytical expressions for corrections to the lepton anomaly are obtained for the first time in the whole interval 0
