Human pheromones?

  • Chapter
The Psychological Basis of Perfumery

Abstract

The evidence concerning the occurrence and importance of pheromones in insects and numerous species of animals, such as rats, mice, rabbits and pigs, is incontrovertible. Whether humans produce odorous substances which influence other humans, most likely at an unperceived level, however, is still a question which is strongly debated — hence the question mark after the title. The possibility of human pheromones was argued for cogently three decades ago by Wiener (1966) and, more recently, by Comfort (1971, 1974). Since that time numerous experiments have been designed by researchers in attempts to determine whether human pheromones exist, and it is the purpose of this chapter to survey critically the growing number of experimental results and to discuss the problems inherent in the design and interpretation of such experiments.
