      abstract     = {Female chemical signals underlie the advertising of sexual
                      receptivity and fertility. Whether the body odor of a
                      pregnant woman also has a signaling function with respect to
                      male behavior is yet to be conclusively established. This
                      study examines how the body odors of ovulating and pregnant
                      women differentially affect the behavior of heterosexual
                      men.Body odor samples were collected from 5 pregnant women
                      and 5 matched controls during ovulation. In a double-blind
                      functional magnetic resonance imaging design, 18
                      heterosexual men were exposed to female body odors during
                      ovulation (OV) and pregnancy (PRG) while being required to
                      indicate the attractiveness of concurrently presented female
                      portrait images. The participants were also required to
                      indicate whether they assumed a depicted woman was
                      pregnant.While neither OV nor PRG altered the perceived
                      attractiveness of a presented face, the men tended to
                      identify the women as pregnant while exposed to a PRG body
                      odor. On the neural level, OV activated a network of the
                      frontotemporal and limbic regions, while PRG activated the
                      superior medial frontal gyrus.The results suggest that the
                      detection of sexual availability activates the male brain
                      regions associated with face processing and
                      reward/motivation, whereas sensing pregnancy activates a
                      region responsible for empathy and prosocial behavior. Thus,
                      the female body odor during pregnancy likely helps foster
                      circumstances conducive to the future care of offspring
                      while the body odor advertising sexual availability promotes
                      mating behavior. The brains of heterosexual men may be
                      capable of unconsciously discriminating between these two
                      types of olfactory stimuli.},
