Adiposity, compared with masculinity, serves as a more valid cue to immunocompetence in human mate choice - PMC
According to the ‘good genes’ hypothesis, females choose males based on traits that indicate the male's genetic quality in terms of disease resistance. The ‘immunocompetence handicap hypothesis’ proposed that secondary sexual traits serve as ...

Antibody response was significantly correlated with facial attractiveness (r69 = 0.43, p < 0.001), in line with previously reported findings using the current sample [29]. In the multiple regression model, facial adiposity significantly predicted facial attractiveness, whereas facial masculinity and antibody response did not (figure 1b). Both adiposity and masculinity were significantly predicted by antibody response (figure 1b). The electronic supplementary material, figure S2 illustrates the facial features associated with high- and low-antibody response. As with the body measurements, adiposity significantly mediated the relationship between antibody response and facial attractiveness, whereas masculinity did not (see table 1 and the electronic supplementary material, table S2). There was no significant difference between the specific indirect effect through adiposity and the specific indirect effect through masculinity (table 1). Circulating testosterone levels were significantly correlated with adiposity (r69 = 0.52, p < 0.001) and masculinity (r69 = 0.38, p = 0.001). There was no significant difference in the testosterone–adiposity and testosterone–masculinity correlations (Steiger's Z = 1.04, d.f. = 66, p = 0.28).
