What does perfume having pheromones do?

Actually quite a lot. However, the power of pheromone compounds to influence behavior of both males and females are much more subtle than the marketing hype out there would have folks believe, nevertheless the effects are quite real.

As science slowly progresses, and actually has bothered to conduct clinical studies into both hormone and pheromone compounds and their affects upon others, it's becoming very clear that individuals do in fact respond to these agents to a certain degree, for instance the hormone compound Oxytocin, it's mood elevating effects are now scientifically confirmed, and confirmed by credible sources nonetheless.

Pheromone perfumes specifically are not generic, depending upon what specific pheromone compounds are used, they will tend to induce different, albeit subtle, changes in others behavior. For instance, the Astrid study which tested the pheromone compound known as Copulins, showed a 150% increase in male testosterone production during the period of exposure. Therefore, the assumption being that a male exposed to Copulins, would most likely then view the female more favorably do to his increased testosterone count while in her presence.

Therefore, various pheromone perfumes, depending upon the specific pheromone compounds used, tend to either facilitate social interaction, enhance attraction, or to act as a mood elevating agent, as in the case of Oxytocin for instance, however as I said, the effects are much more subtle that is commonly advertised.
