Permissiveness occurs when one hormone is necessary for another hormone to exert its full effect, but it does not necessarily mean that one hormone is more dominant than another hormone. Synergism occurs when two hormones have a greater effect together than the sum of their individual effects. Antagonism occurs when one hormone opposes the action of another hormone, either by competing for the same receptor or by inhibiting the production or release of the other hormone. ADH and oxytocin are an example of complementary hormones, not antagonistic hormones, because they have different, but complementary, roles in regulating water balance and uterine contractions.
