  We propose a new mechanism to generate baryons. Electroweak strings produced
at the electroweak phase transition will introduce anomalous currents through
interactions of the strings with the background electromagnetic field and
through changes in the helicity of the string network. These anomalous currents
will produce fluctuations in the baryon and lepton number. We show that in the
two-Higgs model corrections to the action coming from the effective potential
introduce a bias in the baryon asymmetry that leads to a net baryon number
production.
