In many non-human animals, a lordosis posture in a female is a reliable signal of sexual receptivity. Recently, it has been argued that this posture is linked to a similar signal between men and women. The current research across three investigations aimed to test the predictions arising from the sexual receptivity hypothesis of lordosis posture.</p><h3>Methods</h3><p>Using realistic 3D generated stimuli, both men and women viewed women’s arched back postures in standing, supine and quadruped poses (Studies 1 and 2) and were asked to rate them for perceived sexual receptivity. In Study 3, a male model was used.</p><h3>Results</h3><p>In Study 1 we tested whether the arched back posture in women is an indicator of sexual receptivity. Results showed that both men and women associated increases in the arch of the back with higher sexual receptivity in women. Study 2 predicted and confirmed that sexual receptivity is also perceived from non-standing postures, namely supine and quadruped poses. Study 3 tested the prediction that the perception of sexual receptivity is specific to the posture being adopted by women.</p><h3>Conclusion</h3><p>Collectively this research provides support for the sexual receptivity hypothesis of lordosis posture by showing that sexual receptivity is perceived by an increase in the arch of the back (Study 1), it is perceived as sexually receptive irrespective of the body posture (Study 2), and this is specific to women (Study 3).</p></div>","PeriodicalId":7178,"journal":{"name":"Adaptive Human Behavior and Physiology","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44885433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In humans, the link between immunocompetence and mate value has found circumstantial support by way of both expressed mate preferences for healthy partners, and via preferences for attractive phenotypes that are ostensibly linked to immune functioning. We examined whether a biological marker of immunocompetence, salivary immunoglobulin A (sIgA), along with self-reported frequency and severity of symptoms of poor health predicted individuals’ reported mate value and mating behavior in a sample of 691 young adults. Our measures of immunocompetence (sIgA and symptoms of poor health) correlated significantly with one another, suggesting sIgA is a viable marker of general immune function in young adults. We then examined the independent contributions of these variables to mate value, controlling for age, sex, and body mass index (BMI). Results showed that sIgA (positively) and poor health (negatively) predicted mate value, but not lifetime number of sex partners or current romantic relationship status. These findings suggest that those with better health and immune function report being more desirable as mating partners but support past research showing null links to reported mating behavior.
