“…Thanks to an extensive body of experimental research on the mechanisms of the Bruce effect in rodents (specifically, in mice), we have a very good understanding of how males (and their secretions) mediate loss prior to successful implantation (Figure ). After successful implantation, however, we have comparatively little knowledge of the mechanisms for any form of male‐mediated prenatal loss, particularly for nonrodents.…”

“…Under the “olfactory memory hypothesis,” female mice form a chemical memory of the sire—mediated by noradrenaline release in the accessory olfactory bulb—during a sensitive period immediately after mating. This memory then selectively “gates” any further transmission of the chemosignal to the accessory olfactory bulb, through the medial amygdala, and to the hypothalamus . In other words, rather than ensuring that novel males do trigger the Bruce effect, the mechanism ensures that familiar males do not trigger it .…”

Sexually selected infanticide has been the subject of intense empirical and theoretical study for decades; a related phenomenon, male‐mediated prenatal loss, has received much less attention in evolutionary studies. Male‐mediated prenatal loss occurs when inseminated or pregnant females terminate reproductive effort following exposure to a nonsire male, either through implantation failure or pregnancy termination. Male‐mediated prenatal loss encompasses two sub‐phenomena: sexually selected feticide and the Bruce effect. In this review, we provide a framework that explains the relationship between feticide and the Bruce effect and describes what is known about the proximate and ultimate mechanisms involved in each. Using a simple model, we demonstrate that male‐mediated prenatal loss can provide greater reproductive benefits to males than infanticide. We therefore suggest that, compared to infanticide, male‐mediated prenatal loss may be more prevalent in mammalian species and may have played a greater role in their social evolution than has previously been documented.

“…Conspecific olfactory cues are processed through main and accessory olfactory bulbs then directly and indirectly to the medial amygdala [63,64]. OT synthesis in the medial amygdala plays a significant role in the reception of social odorant cues and the expression of approach behavior to social stimuli [65,66].…”

“…In the accessory olfactory system, pheromones are received at the vomeronasal organ and then processed at the accessory olfactory bulb (AOB) and, subsequently, higher brain regions, most importantly the medial amygdala . In the main olfactory system, odours are registered at the main olfactory epithelium and then processed at the main olfactory bulb (MOB) and, subsequently, by the anterior olfactory nucleus (AON), the piriform cortex (PC) and the cortical amygdala . The PC is more than a primary olfactory relay and plays an active role from sensory to more cognitive aspects of odour perception.…”

In the main olfactory system, odours are registered at the main olfactory epithelium and are then processed at the main olfactory bulb (MOB) and, subsequently, by the anterior olfactory nucleus (AON), the piriform cortex (PC) and the cortical amygdala. Previously, we reported populations of vasopressin neurones in different areas of the rat olfactory system, including the MOB, accessory olfactory bulb (AOB) and the AON and showed that these are involved in the coding of social odour information. Utilising immunohistochemistry and a transgenic rat in which an enhanced green fluorescent protein reporter gene is expressed in vasopressin neurones (eGFP-vasopressin), we now show a population of vasopressin neurones in the PC. The vasopressin neurones are predominantly located in the layer II of the PC and the majority co-express the excitatory transmitter glutamate. Furthermore, there is no sex difference in the number of neurones expressing vasopressin. Electrical stimulation of the lateral olfactory tract leads to a significant increase in the number of Fos-positive nuclei in the PC, MOB, AOB, dorsal AON and supraoptic nucleus (SON). However, there was only a significant increase in Fos expression in vasopressin cells of the PC and SON. Thus, functionally distinct populations of vasopressin cells are implicated in olfactory processing at multiple stages of the olfactory pathway.
