Study Finds Certain Female Body Odors During Ovulation Can Boost Men’s Mood and Reduce Stress

Researchers at the University of Tokyo have discovered that specific compounds in women’s body odor, which increase during ovulation, can positively influence men’s mood and emotional state. When men were exposed to a blend of these compounds mixed with a model armpit odor, they rated the scent as more pleasant and associated images of women with these samples as more attractive and feminine. Furthermore, the scent reduced stress levels in men, as evidenced by a suppression of salivary amylase, a stress biomarker.

Although this study showed that female body odor can subtly shape male emotions and perceptions, researchers caution that these findings do not confirm the existence of human pheromones—chemical signals known to affect behavior in other species. Instead, these compounds may contribute to subtle, non-conscious communication between men and women, possibly influencing social interaction and attraction.

This research helps illuminate the complex role that human body odors may play in emotional and social communication but stops short of establishing a direct causal effect akin to pheromones.

Disclaimer: The described findings are based on controlled scientific research and should not be interpreted as definitive proof of human pheromones or guaranteed effects on mood or attraction in everyday life. Individual responses can vary, and broader social and psychological factors also play critical roles in human interactions.
