Sociosexuality, testosterone, and life history status: prospective associations and longitudinal changes among men in Cebu, Philippines

Abstract

Sociosexuality is defined as an individual's interest in uncommitted sexual activity and can be measured in terms of both psychological orientations and behavioral expression. In socio-ecological contexts in which adults monogamously partner and 1 digitalcommons.unl.edu

Are Sexual Desire and Sociosexual Orientation Related to Men’s Salivary Steroid Hormones?

“…95%CI = [-0.16; -0.00]). These results are in line to Gettler and colleagues (Gettler et al 2019 ) findings that changes in men’s testosterone levels are not related to changes in sociosexuality scores. Further, they suggest no compelling evidence that changes in men’s cortisol levels or the interaction between testosterone and cortisol are linked to changes in sociosexuality or sexual desire, an association which, to our knowledge, has not been investigated in any previous study.…”

“…Although this is not optimal, we believe that, due to our longitudinal design, we should have a better test power than most previous work. Especially for within-subjects analyses, as our number of observations (= 283) largely exceeds those of Gettler and colleagues (Gettler et al 2019 ) analyses (= 99), which is the only study investigating within-subjects changes in testosterone and sociosexual orientation that has been published so far. Further, our sample size matches the one of Raisanen and colleague‘s (Raisanen et al 2018 ) study (to our knowledge the only study investigating an interaction effect of testosterone and cortisol) for between-subjects analyses.…”

“…In addition, it remains unclear whether natural changes in testosterone are related to sexual desire or sociosexual orientation as well. Importantly, the only study that reports longitudinal results (within-subjects changes) in a non-clinical sample does not find compelling evidence for a link between within-men changes in sociosexual orientation and testosterone (Gettler et al 2019 ).…”

“…No significant main or interaction effects of sociosexual behavior or attitudes (and relationship status; all βs < 0.19, ps > 0.05). Gettler et al 2019 N = 288 men at baseline n = 99 men at follow-up n = 99 completed two sessions (five years apart), all other participants completed one session. Cross-sectional and longitudinal analyses (the latter with 99 observations).…”

Are sexual desire and sociosexual orientation related to men’s salivary steroid hormones?

“…Importantly, the only study that reports longitudinal results (within-subjects changes) in a non-clinical sample does not find compelling evidence for a link between within-men changes in sociosexual orientation and testosterone (Gettler et al, 2019).…”
