It appears that exponentially increasing amounts of hCG are required to prolong the functional lifespan of the corpus luteum, which explains why the corpus luteum survives early pregnancy but regresses during unfertilized menstrual cycles, despite the fact that LH and hCG have similar actions on the corpus luteum.69 Thus, administration of antisera to hCG in early gestation causes pregnancy termination in primate models, and immunization against hCG epitopes may be an effective contraceptive vaccine.70 Other roles for hCG have been suggested based on the discovery of LH/CG receptors in the fallopian tube, endometrium, and myometrium
