  Recent electroweak two-loop corrections in the Minimal Supersymmetric
Standard Model (MSSM) are reviewed. They have been obtained with the help of
the programs FeynArts and TwoCalc, making use of the recently completed MSSM
model file for FeynArts. Short examples of how to use the two codes together
with the analytic result for the O(Gf^2 m_t^4) corrections to the
$\rho$-parameter in the MSSM are presented.
