We evaluate the contribution to the nucleon-nucleon interaction due to correlated πρ exchange in the π, ω, and A1/H1 channels by means of dispersion-theoretic methods based on a realistic meson exchange model for the interaction between π and ρ mesons. These processes have substantial effects: In the pionic channel it counterbalances the suppression generated by a soft πNN form factor of monopole type with a cutoff mass of about 1 GeV; in the ω-channel it provides nearly half of the empirical repulsion, leaving little room for explicit quark-gluon effects.
