“…Alternatively, it could be a low-cost functionless byproduct of processes that function primarily to increase intrasexual competitiveness in response to changes in testosterone that occur over longer timespans, such as over pubertal development. Since some (but not all) studies have reported small increases in testosterone around ovulation (Caruso et al, 2014;Dabbs, 1990;Dabbs & de La Rue, 1991), we do not discount the possibility that increased intrasexual competitiveness when testosterone is high may occur because of direct or indirect benefits Hahn 14 associated with increased intrasexual competitiveness around ovulation (see Fisher, 2004).…”

“…Moreover, intrasexual competitiveness did not differ between these late-follicular or mid-luteal phases. Since hormonal contraceptive use lowers testosterone levels in women (Zimmerman et al, 2014) and evidence that testosterone levels change between the late-follicular and mid-luteal phases is mixed (Dabbs, 1990;Dabbs & de La Rue, 1991; see also Caruso et al, 2014), Cobey et al (2013) speculated that the observed changes in women's intrasexual competitiveness may be a consequence of changes in their testosterone levels. Indeed, this explanation would be consistent with findings showing that women's testosterone levels increased after they imagined their partner flirting with an attractive woman (Ritchie & van Anders, 2014) or were exposed to olfactory cues associated with ovulation in other women (Maner & McNulty, 2013).…”

indicating that women reported greater intrasexual competitiveness when testosterone was high. By contrast, there were no significant effects of estradiol, progesterone, estradiol-toprogesterone ratio, or cortisol and no significant effects of any hormones on reported relationship jealousy. This is the first study to demonstrate correlated changes in measured testosterone levels and women's reported intrasexual competitiveness, implicating testosterone in the regulation of women's intrasexual competitiveness.

“…Likewise, further studies could consider the influence of cycle phase in regularly cycling women, as there is some evidence to suggest that testosterone increases near to ovulation (e.g. Alexander, Sherwin, Bancroft, and Davidson 1990;Bloch, Schmidt, Su, Tobin, and Rubinow 1998;Dabbs 1990;Morris, Udry, KhanDawood, and Dawood 1987;Schultheiss, Dargel, and Rohde 2003;Welling et al 2007, but see Dabbs 1990;Liening, Stanton, Saini, and Schultheiss 2010;Schultheiss et al 2003), although this effect is unlikely to be large since daily fluctuations (due to circadian rhythm) and seasonal fluctuations in testosterone are often greater than cyclical changes.…”

How to achieve dominance in a group is a recurrent challenge for individuals of many species, including humans. Previous research indicates that both relationship status and contraceptive use appear to moderate women's testosterone levels. If testosterone contributes to dominance, this raises the possibility for group differences in dominance between single and partnered women, and between users and non-users of hormonal contraception. Here, we examine associations between relationship status and use/non-use of hormonal contraception and women's self-reported social dominance. In a sample of 84 women, we replicate previous research documenting a significant positive correlation between women's saliva testosterone levels and their selfreported dominance. Consistent with other literature, we also find that women using hormonal contraception have significantly lower testosterone than those who are regularly cycling and that partnered women have significantly lower testosterone than single women. Although we do not find a main effect of either relationship status or hormonal contraceptive use status on women's reported levels of dominance, the interaction between these variables predicted reported dominance scores. This interaction remained significant when participant age and testosterone values were added to the model as covariates. We discuss these results in the context of the existing literature on testosterone and women's dominance behaviour and with respect to the evolutionary benefits of social dominance in women.

“…Subjects were included whose blood samples were taken between 07:00 and 09:00 in order to minimize the in¯uence of diurnal rhythm of leptin 20 and androgen levels. 21 Subjects who were pregnant, had diabetes or subclinical hypothyroidism, or had a history of prior myocardial infarction or stroke, or were using estrogen replacement therapy, oral contraceptives or antihypertensive agents were excluded. Furthermore, women with irregular menstruations were excluded.…”

A strong association between biologically active testosterone and leptin in non-obese men and women is lost with increasing (central) adiposity

et al. 2001

OBJECTIVE:In both humans and rodents, males have lower levels of leptin than females at any level of adiposity. Experimental data support the idea that testosterone exerts a negative in¯uence on leptin levels. There are, however, major inconsistencies in available data concerning the possible association between androgenicity and leptin in humans. Reasons could be the in¯uence of androgenicity on leptin production being dependent on body composition, and incomplete measures of biologically active testosterone levels. In the present study we have characterized the relationship between biologically active testosterone and leptin after careful strati®cation for gender and adiposity. DESIGN AND SUBJECTS: Healthy subjects (n 158; 85 men and 73 pre-and postmenopausal women) from the Northern Sweden MONICA (Monitoring of Trends and Determinants in Cardiovascular Disease) population were studied with a crosssectional design. MEASUREMENTS: Anthropometric measurements (body mass index (BMI) and waist circumference) and oral glucose tolerance tests were performed. Circulating levels of leptin, insulin, testosterone, androstenedione, sex hormone-binding globulin (SHBG) and insulin-like growth factor-1 (IGF-1) were measured by radioimmunoassays or microparticle enzyme immunoassays. Apparent concentrations of free testosterone and non-SHBG-bound testosterone were calculated. RESULTS: After adjustments for age, BMI and insulin, leptin levels were inversely correlated to testosterone levels in non-obese men (r À0.56, P`0.01) and obese women (r À0.48, P`0.05). In contrast, leptin and testosterone correlated in a positive manner in non-obese women (r 0.59, P`0.01). Levels of SHBG were negatively associated with leptin in men with low waist circumference (r À0.59, P`0.01). The following factors were associated with leptin in a multivariate model: low levels of biologically active testosterone and SHBG in men with low and medium waist circumference, insulin in men with high waist circumference, high levels of testosterone and insulin in non-obese women, and BMI in obese women. CONCLUSION: We conclude that low leptin levels are associated with androgenicity in non-obese men and women and that the direction of this association is dependent on gender and body fat distribution. Based on these results we suggest that the relation between testosterone and leptin contributes to the gender difference in circulating leptin levels.
