  The class of `Asymmetric Dark Matter' scenarios relies on the existence of a
primordial particle/anti-particle asymmetry in the dark sector related to the
baryon asymmetry as a way to address the observed similarity between the
baryonic and dark matter energy densities today. Focusing on this framework we
calculate the evolution of the dark matter relic abundance in the presence of
particle/anti-particle oscillations. We show how oscillations re-open the
parameter space of asymmetric dark matter models, in particular in the
direction of allowing large (WIMP-scale) DM masses. Finally, we constrain the
parameter space in this framework by applying up-to-date bounds from indirect
detection signals on annihilating DM.
