Angular correlations arising from particle-particle propagation in nuclear matter are presented. Their account emerges from an exact treatment of the Pauli blocking on intermediate states while retaining the angular structure of the energy denominator. As a result, a correlation form factor appears from the Cauchy principal-value of the particle-particle propagator, while the imaginary part becomes structurally different from those in Lippmann-Schwinger-type equations. In selfconsistent runs these features alter the behavior of the mass operator near the Fermi surface, modifying the saturation properties of infinite nuclear matter.
