It appears from all my reading that the VNO isnt involved in the processing of most of the known pheromones in humans as I posted in that thread with some studies designed to confirm this. Other mammals have also been shown to process beyond the VNO. Hedione a man made substance does trigger one of the five vomeronasal-type 1 remaining receptor genes, but not Androstadienone for example so there is no natural pheromone that does. Pheromone effects on the brain are seen with complete blockage of the VNO and those without one…
Some more info in that thread… Its good to see however they are still trying to figure out if it does do anything for humans anymore
