Abstract
We have calculated the fermion contributions to the shift of the position of the poles of the massive gauge boson propagators at two--loop order in the Standard Model. Together with the bosonic contributions calculated previously the full two--loop corrections are available. This allows us to investigate the full correction in the relationship between MS and pole masses of the vector bosons Z and W. Two--loop renormalization and the corresponding renormalization group equations are discussed. Analytical results for the two-loop propagator type diagrams are presented. A new approach of summing multiple binomial sums has been used.
