The gravitino contribution to the one loop gaugino self energy in low energy N = 1 supergravity models derived from superstrings is considered. This contribution is shown to vanish when a supersymmetric regularization procedure is used. An identical conclusion is seen to hold for the contribution of the fermionic component of the gauge singlet chiral supermultiplet that arises out of gaugino condensation in the Hidden ('shadow') sector. Implications for supersymmetry breaking in the observable sector of superstring theories are briefly discussed.
