The activity change during puberty suggests that humans communicate through odors. [4] Several axillary steroids have been described as possible human pheromones: androstadienol, androstadienone, androstenone, androstenol, and androsterone. Androstenol is the putative female pheromone. [5]
Pheromones are chemical messengers produced and emitted by the body that contribute significantly to interpersonal attraction. [8] The two types of pheromones include signal and primer, each playing a distinct role in human behavior. Signal pheromones act as attractants and repellents; they are classified short-term behavioral pheromones.
No study has led to the isolation of true human sex pheromones. [9] [10] While humans are highly dependent upon visual cues, when in close proximity, smells also play a role in sociosexual behaviors. An inherent difficulty in studying human pheromones is the need for cleanliness and odorlessness in human participants. [11]
Pheromones are a factor seen in the mating selection and reproduction in humans. In women, the sense of olfaction is strongest around the time of ovulation , significantly stronger than during other phases of the menstrual cycle and also stronger than the sense in males.

In general, this type of pheromone elicits a rapid response, but is quickly degraded. In contrast, a primer pheromone has a slower onset and a longer duration. For example, rabbit (mothers) release mammary pheromones that trigger immediate nursing behavior by their babies. [20]
While noting that humans (along with elephants and whales) theoretically have the potential to live longer than most other mammals, de Magalhães said that every mammal is still living under ...
