The above patent incorporates the false concept that human pheromones act via the human vomeronasal organ (VNO), which has been shown to be non-functional. Nevertheless, this research and marketing group (see below) might have been the first to show effects of a progesteronic (luteal phase) pheromone on testosterone levels in men.
