To determine whether solitary men’s BO smelled dissimilar to the new BO away from hitched men, heterosexual lady players rated men’s BO towards the four characteristics (e.g., sexiness, liking). According to previous browse suggesting male testosterone account was in fact positively ( not notably) in the healthier smell BO critiques (Rantala et al., 2006) and you can single males possess highest quantities of testosterone (elizabeth.g., Booth and you may Dabbs, 1993), we hypothesized you to definitely unmarried men’s BO create smell stronger than you to off partnered men’s room.

We made zero a priori forecasts on the differences between unmarried and you will married men’s face appeal ratings. Ultimately, to be sure the capacity to compare the BO and deal with evaluations off solitary and you can married guys, participants rated the latest stimuli away from about three unmarried and you can about three partnered unknown guys.
