“…Our results for the relationship between fecal androgens and rank in female mandrills are similar to those reported for female yellow baboons (fecal testosterone, Altmann et al, 1995), ring-tailed lemurs (fecal and salivary testosterone, von Engelhardt et al, 2000), and bonobos (fecal 5a-androstan-17a-ol-3-one, Sannen et al, 2004), in which rank is also not related to androgens. However, our findings differ from those for captive talapoins (serum testosterone, Batty et al, 1986), hybrid baboons (fecal testosterone, Beehner et al, 2005), and Barbary macaques (fecal 17b-OH-androgens, Grant et al, 2011), in which dominant females show higher androgen levels than subordinates.…”

“…However, there is no relationship between rank and fecal testosterone in female yellow baboons (Papio cynocephalus, Altmann et al, 1995), between rank and fecal and salivary testosterone in ring-tailed lemurs (Lemur catta, von Engelhardt et al, 2000), or between rank and fecal 5a-androstan-17a-ol-3-one in bonobos (Pan paniscus, Sannen et al, 2004).…”

ABSTRACT A comprehensive understanding of the role of androgens in reproduction, behavior and morphology requires the examination of female, as well as male, hormone profiles. However, we know far less about the biological significance of androgens in females than in males. We investigated the relationships between fecal androgen (immunoreactive testosterone) levels and reproductive status, age, dominance rank, fetal sex and a secondary sexual trait (facial color) in semi-free-ranging female mandrills, using samples collected from 19 reproductively mature females over 13 months. Fecal androgens varied with reproductive status, being highest during gestation. Fecal androgens began to increase at 3 months of gestation, and peaked at 5 months. This pattern is more similar to that found in a platyrrhine than in other cercopithecine species, suggesting that such patterns are not necessarily phylogenetically constrained. Fecal androgens did not vary systematically with rank, in contrast to the relationship we have reported for male mandrills, and in line with sex differences in how rank is acquired and maintained. Offspring sex was unrelated to fecal androgens, either prior to conception or during gestation, contrasting with studies of other primate species. Mean facial color was positively related to mean fecal androgens across females, reflecting the same relationship in male mandrills. However, the relationship between color and androgens was negative within females. Future studies of the relationship between female androgens and social behaviour, reproduction and secondary sexual traits will help to elucidate the factors underlying the similarities and differences found between the sexes and among studies.

“…In the study by Carlson et al [44] on female meerkats, E 2 rather than T was associated with dominant position in the social structure. Moreover, no association between T levels and dominance rank was found in female African elephants [45], lemurs [46] and female bonobos [47]. Our study constitutes yet another evidence that this association may not hold true either in human females.…”

“…For example, high basal testosterone levels are related to higher dominance rank in Old World monkeys such as Rhesus Monkeys (Bernstein et al, 1983;Rose et al, 1975) and Crab-eating Macaques (Clarke et al, 1986;Czoty et al, 2009), but also in our close living relatives, Chimpanzees (Muehlenbein et al, 2004;Muller and Wrangham, 2004;Sobolewski et al, 2012). However, among our other closest relative, the more egalitarian bonobos, there is no association between male dominance rank and basal testosterone levels (Sannen et al, 2004).…”

This article examines the role of basal testosterone as a potential biological marker of leadership and hierarchy in the workplace. First, we report the result of a study with a sample of male employees from different corporate organizations in the Netherlands (n=125). Results showed that employees with higher basal testosterone levels reported a more authoritarian leadership style, but this relationship was absent among those who currently held a real management position (i.e., they had at least one subordinate). Furthermore, basal testosterone levels were not different between managers and non-managers, and testosterone was not associated with various indicators of status and hierarchy such as number of subordinates, income, and position in the organizational hierarchy. In our meta-analysis (second study), we showed that basal testosterone levels were not associated with leadership in men nor in women (9 studies, n=1103). Taken together, our findings show that basal testosterone is not associated with having a leadership position in the corporate world or related to leadership styles in leaders. We suggest that basal testosterone could play a role in acquiring leadership positions through dominant and authoritarian behavior.
