Unexpected features of the BaBar data on e+e- in baryon-antibaryon crosssections are discussed. These data have been collected, with unprecedentedaccuracy, by means of the initial state radiation technique, which isparticularly suitable in giving good acceptance and energy resolution atthreshold. A striking feature observed in the BaBar data is the non-vanishingcross section at threshold for all these processes. This is the expectation dueto the Coulomb enhancement factor acting on a charged fermion pair. In the caseof e+e- in proton-antiproton it is found that Coulomb final state interactionslargely dominate the cross section and the form factor is |G^p(4M^2_p)|~1,which could be a general feature for baryons. In the case of neutral baryons aninterpretation of the non-vanishing cross section at threshold is suggested,based on quark electromagnetic interaction and taking into account theasymmetry between attractive and repulsive Coulomb factors. Besides strangebaryon cross sections are compared to U-spin invariance predictions.
