The only thing that might be an indicator of pheromones in humans is a
phenomenon that occurs
among women:
When women are around each other for any length of time, their
menstral cycles will start to coincide and, in time, will run on the same timeline. This is not just some
freak coincidence that happened to me once, it has been proven time and time again
all over the world. Within the past decade, some researchers have started debating whether the nature of this occurance is caused by pheromones, marking the first and only evidence of
human pheromone interaction.
