more attractive during the high-fertility ovulatory phase than during other phases in the menstrual cycle. In particular, women’s bodily odour may influence important aspects of male mating behaviour, but the precise nature of this phenomena remains to be elucidated.Twenty-six men and five women participated in the study. Each woman wore a cotton Tshirt during the night for 3 days during the ovulatory phase, after which the regions of the Tshirt
that had been in contact with the woman’s chest, armpits, and back, were cut out of the
garment. We evaluated the changes in testosterone and cortisol levels in the saliva of men
who smelled these cloth pieces. The odour emitted from the backs of women in the ovulatory
phase was found to increase testosterone secretion in men, whereas the odour emitted
from the chests of women in the ovulatory phase reduced cortisol secretion in men. These
results suggest that the odour of specific body parts of women modulate unconscious physiological
reactions in men., PLoS ONE, 15(3), art.no.e0230838; 2020},
