Prolactin promotes oxytocin and vasopressin release by activating neuronal nitric oxide synthase

"Prolactin enhances nNOS activity in the PVN and SON, thereby contributing to the regulation of OXT and AVP release. This mechanism likely contributes to the regulation of processes beyond those of female reproduction."

Oxytocin and vasopressin in the medial amygdala differentially modulate approach and avoidance behavior toward illness-related social odor

This study shows an essential role of OT and AVP receptors, especially type 1a, in the MeA in regulating approach/avoidance behaviors, respectively, in social odorant communication.
