We study the quantum-to-classical transition induced by the loss of coherence in the double-slit experiment with large molecules. We introduce the effects of loss of coherence by considering a propagator that includes such effects. We calculate the fringe visibility and the volume of the negative part of the Wigner function and observe that these quantities decrease when the effects of loss of coherence increase.
