  Loop Quantum Cosmology is an appealing quantum completion of classical
cosmology, which brings along various theoretical features which in many cases
offer remedy or modify various classical cosmology aspects. In this paper we
address the gravitational baryogenesis mechanism in the context of Loop Quantum
Cosmology. As we demonstrate, when Loop Quantum Cosmology effects are taken
into account in the resulting Friedmann equations for a flat
Friedmann-Robertson-Walker Universe, then even for a radiation dominated
Universe, the predicted baryon-to-entropy ratio from the gravitational
baryogenesis mechanism is non-zero, in contrast to the Einstein-Hilbert case,
in which case the baryon-to-entropy ratio is zero. We also discuss various
other cases apart from the radiation domination case, and we discuss how the
baryon-to-entropy ratio is affected from the parameters of the quantum theory.
In addition, we use illustrative exact solutions of Loop Quantum Cosmology and
we investigate under which circumstances the baryon-to-entropy ratio can be
compatible with the observational constraints.
