  The current status of the theoretical predictions for the electroweak
precision observables M_W, sin^2_theta_eff and m_h within the MSSM is briefly
reviewed. The impact of recent electroweak two-loop results to the quantity
Delta_rho is analysed and the sensitivity of the electroweak precision
observables to the top-quark Yukawa coupling is investigated. Furthermore the
level of precision necessary to match the experimental accuracy at the next
generation of colliders is discussed.
