The creation of spinor particles in an arbitrary external field from states described by quadratic density matrices is considered. Expressions are obtained for the spectra of the created particles. It is shown that in the case of the creation of fermions (spin 1/2) in the Friedmann universe from states described by a thermal density matrix statistical effects significantly suppress the particle creation process.
