In the prairie vole, oxytocin released into the brain of the female during sexual activity is important for forming a pair bond with her sexual partner.Vasopressin appears to have a similar effect in males.Oxytocin modulates fear responses by enhancing the maintenance of social memories.Rats that are genetically modified to have a surplus of oxytocin receptors display a greater fear response to a previously conditioned stressor.Amastatin, bestatin (ubenimex), leupeptin, and puromycin have been found to inhibit the enzymatic degradation of oxytocin, though they also inhibit the degradation of various other peptides, such as vasopressin, met-enkephalin, and dynorphin A.In the hypothalamus, oxytocin is made in magnocellular neurosecretory cells of the supraoptic and paraventricular nuclei, and is stored in Herring bodies at the axon terminals in the posterior pituitary.

The two genes are believed to result from a gene duplication event; the ancestral gene is estimated to be about 500 million years old and is found in cyclostomata (modern members of the Agnatha).The activity of the PAM enzyme system is dependent upon vitamin C (ascorbate), which is a necessary vitamin cofactor.By chance, sodium ascorbate by itself was found to stimulate the production of oxytocin from ovarian tissue over a range of concentrations in a dose-dependent manner.This possibly plays a role in the emotional bonding between humans and dogs.Oxytocin is typically remembered for the effect it has on prosocial behaviors, such as its role in facilitating trust and attachment between individuals.
