The Bruce Effect

The discussion centers on the intriguing Bruce effect, where female mice can terminate pregnancies based on the scent of non-stud males, showcasing a robust biological response. While humans possess a vestigial vomeronasal organ, the implications for pheromone effects remain uncertain, as social chemo signaling may still occur through the main olfactory system. The complexity of studying human anatomy postmortem raises questions about the functionality of this organ in humans.
