  Sterile neutrino dark matter is expected to suppress structure formation at
small astrophysical scales. The details of the suppression depend on the
sterile neutrino production mechanism in the early universe. In this
proceeding, we focus on the most popular cases of resonant production (via the
mixing between active and sterile neutrinos) and scalar decay production (via
the decay of a hypothetical scalar singlet). We first review current
constraints from structure formation before discussing how the sterile neutrino
dark matter hypothesis can alleviate the overabundance problem of dwarf
galaxies in the local universe.
