We show that certain models for neutrino masses that lead to the MSW explanation of the solar neutrino data and/or the hot dark matter component in the universe can also naturally allow for the successful generation of the cosmological baryon asymmetry at the electroweak scale. This follows either because the experimental Higgs boson mass limit is weakened due to the smaller production rate and the presence of sizeable invisible decays involving majoron emission, or due to the effect of additional electrically charged scalar bosons which substantially modify the condition for succesful baryogenesis.
