We present here some arguments to support our suggestion that data on the helicity structure for the hard exclusive electroproduction of ρ mesons at HERA (and in possible future high-energy electron-proton colliders) provide useful information to constrain the κ-shape of the unintegrated gluon distribution in the proton.
