By definition and according to evolutionary theory, pheromones work within a species. These pheromones are detected by us through the nose in the Vomeronasal Organ. How do pheromones work?

Human pheromones, on the other hand, are highly individualized, and not always noticeable. Many pheromones have been found in nature that does not depend on a VNO to function and there have been documented cases of definite reactions to pheromones in animals without a VNO. Even though scientists don’t know exactly how this organ works when it comes to humans, they do know that it works nevertheless. Do pheromones work the same way in humans as animals and plants? What are pheromones? However, not all smells are pheromones.
