  I propose a new mechanism for baryogenesis, in which the out-of-equilibrium
condition is not neccessary. When the electroweak symmetry is broken
spontaneously, left-handed neutrinos may get Majorana masses containing
$CP-$violating phases. This induces a lepton asymmetry spontaneously, which is
then converted to a baryon asymmetry in the presence of the sphaleron field.
