The low energy theorem based on chiral symmetry for the photoproduction of neutral pions from proton at threshold is reviewed in the light of recent experimental results from Saclay and Mainz. There is no appreciable disagreement at threshold but the energy dependence of the threshold amplitude remains unexplained. A critique of the assumptions made in deriving low energy theorems by various methods is presented.
