Abstract
A review is given on the quantum correction in the -- mass correlation at the electroweak two-loop level, as derived from the calculation of the muon lifetime in the Standard Model. Exact results for and the -mass prediction including corrections with fermion loops are presented and compared with previous results of a next-to-leading order expansion in the top-quark mass.
