•A predator-prey model incorporating the cost of fear into prey reproduction.•Strong anti-predator responses can stabilize the predator-prey system by excluding the existence of periodic solutions.•Model undergoes Hopf bifurcation with respect to prey birth rate r0.•Fear effect can stabilize the pre...
