Courtship stimulates aromatase activity in preoptic area of brain in male ring doves

SD Dudley, RS Salisbury, EK Adkins-Regan and J Weisz

Aromatase activity was quantified in vitro in different regions of the basal forebrain of male ring doves at various times after the initiation of courtship. By 24 h after the introduction of a female dove into the cage of a male, there was a significant, nearly two-fold, increase in aromatase activity which was confined to the ventromedial preoptic area (VM-POA) where enzyme activity was concentrated. This increase in aromatase activity, which was sustained through day 5 of courtship, presumably serves to activate nest-oriented behavior.
