We discuss muon and electron lepton-number nonconservation due to renormalization effects of the scalar-lepton mass matrix in spontaneously broken N=1 supergravity theories. Differently from the case of massless or Dirac neutrinos, we find that if neutrinos are Majorana particles in a "seesaw" scheme the couplings photino-lepton-scalar-lepton lead to sizable rates for the processes e and +nucleuse+nucleus. We discuss the constraints derived from the present experimental bounds.
