In this review, we present several variants of left-right symmetric models in the context of neutrino masses and leptogenesis.
In particular, we discuss various low scale seesaw mechanisms like linear seesaw, inverse seesaw, extended seesaw and their implications to
lepton number violating process like neutrinoless double beta decay. We also visit an alternative framework of left-right models with
the inclusion of vector-like fermions to analyze the aspects of universal seesaw. The symmetry breaking
of left-right symmetric model around few TeV scale predicts the existence
of massive right-handed gauge bosons $W_R$ and $Z_R$ which might be detected at the LHC in near future. If such signals are detected at the LHC
that can have severe implications for leptogenesis, a mechanism to explain the observed baryon asymmetry
of the Universe. We review the implications of TeV scale left-right symmetry breaking for leptogenesis.

Keywords: Left right symmetry, neutrino mass, leptogenesis, neutrinoless double beta decay, low scale seesaw
