The paper addresses the question of existence of coherent states of fermions (apart from those defined via Grassamnn variables) analogous to bosonic coherent states. We use four different definitions of coherent states and show that no fermion states satisfy them. Moreover, properties of fermionic correlation functions are discussed in detail.
