TL;DR
The similarities in the effects of the hormonal manipulations on paternal responsiveness and AVP immunoreactivity provide further support for the hypothesis that AVP-ir projections of the stria terminalis and medial amygdaloid nucleus are implicated in paternal behavior.
Abstract
Castration reduced paternal responsiveness of male prairie voles (Microtus ochrogaster). Castration also reduced the number of vasopressin immunoreactive (AVP-ir) cells in the bed nucleus of the stria terminalis (BST) and medial amygdaloid nucleus (MA), as well as the density of AVP-ir fibers in the lateral septum. Testosterone treatment of castrated voles prevented these changes. The similarities in the effects of the hormonal manipulations on paternal responsiveness and AVP immunoreactivity provide further support for the hypothesis that AVP-ir projections of the BST and MA are implicated in paternal behavior.

Since the vasopressin fiber density was found to decrease drastically in the lateral septum after lesioning the bed nucleus of the stria terminalis, the vasOPressin cells found in this area are probably the source of these fibers.

Using immunocytochemistry, vasopressin innervation was determined in the brain of the European hamster (Cricetus cricetus) during different seasons, and it was found that the spring period coincides with a dense vasopressive innervation in many brain regions in the male hamster, and lower vasoppressin fibre density in some brain areas in the female hamster.
