Abstract

The vomeronasal organ is a chemoreceptive structure located at the base of the nasal septum with direct axonal connections to the accessory olfactory bulb in many terrestrial vertebrates. Pheromones presumably bind to the vomeronasal organ and exert behavioral or physiologic responses, thereby allowing chemical communication between animals of the same species. The presence and function of the vomeronasal organ in humans is debated. A phenotypic classification schema for the human vomeronasal organ is described and applied to 253 human subjects who underwent nasal examination. Of these subjects, only 6 percent possessed a vomeronasal organ with 64 percent unilateral and 36 percent bilateral in appearance. No difference existed in gender, age, or race between those subjects with or without a vomeronasal organ. There is no evidence supporting involutional senescence of this structure. Future investigations should use this phenotypic schema for the vomeronasal organ to allow accurate comparisons of study populations.
