|Hormonal Modification of Social Behavior. IV. The Mechanism of Estrogen-Induced Dominance in Chimpanzees
|| Herbert G. Birch, George Clark
||Two castrate female chimpanzees, one of whom showed unmistakable dominance over the other, were separately administered estrogen and progesterone. The progesterone had the effect of inhibiting swelling of the sex skin. When estrogen was given to the subordinate female she rapidly became dominant, but if swelling of the sexual skin was inhibited by the progesterone this dominance did not appear. Control observations showed no effect on dominance from the progesterone alone. Estrogen given to the dominant animal simply reinforced the dominance if sexual swelling was not inhibited.
