  Traversable Wormhole are amazing astrophysical objects predicted by General
Relativity which are able to connect remote region of space-time. Even if their
existence has not been proved yet they are object of continuous investigation.
From the theoretically point of view, to exist, traversable wormholes need a
special form of energy density termed exotic. Since this exotic source must be
concentrated on the throat of the wormhole, we discuss the implications of
assuming Yukawa-like profiles which could be realize such a configuration.
