Ovulation-induced body scents may enhance a woman's attractiveness to men, though they're not actual pheromones.
A groundbreaking study by a team of biochemists and neurointelligence researchers at the University of Tokyo has shed light on the intricate relationship between female body odor during ovulation and men's mood and perception of attractiveness.
The research, published in the journal iScience, has identified specific scent compounds in female body odor during ovulation that can have a calming effect on men and enhance their perception of female attractiveness.
The study gathered 84 body odor samples from 21 women across their menstrual cycles. Among the 98 different scent compounds identified, three stood out during ovulation: (E)-geranylacetone, Tetradecanoic acid, and (Z)-9-hexadecenoic acid.
When these three compounds were mixed together and added to a background "model" armpit odor, men judged the result as more pleasant and more feminine. This finding suggests that female ovulation is associated with changes in body scent that can positively affect men's mood and perception of attractiveness.
The ovulation odor mix was found to relax men and suppress the increase in the amount of amylase (a stress biomarker) in their saliva. However, it's important to note that the study did not conclude that the identified odor compounds are human pheromones.
The study's participants were all Japanese, and cultural context can influence scent perception. Additionally, genetic variation plays a role in how people perceive scent, with known differences in olfactory receptors across populations. Future studies will focus on tracking how ovulation odors affect activity in brain areas tied to emotion and social perception.
While the study provides a fascinating insight into the effects of ovulation on perception, it's crucial to note that it did not correct for multiple testing comparisons, which increases the chance of false positives.
This research adds a possible scent-based layer to the effects of ovulation on perception, fitting within broader evidence that human body odors convey important social and reproductive information, influencing mood and perception in nuanced ways.
In a broader context, the study supports the idea that human body odor carries subtle chemical signals that can influence mood and perception, particularly in the context of ovulation. These odor signals may serve as invisible cues tied to reproductive fitness, affecting subconscious mood and social perception.
The researchers plan to conduct further studies on how the brain processes these odor compounds to gain a deeper understanding of their psychological effects. The findings could have significant implications for our understanding of human behaviour and evolution.
