{"title":"Sexual Dimorphism in the Facial Morphology and Skin Color in Sub-Saharan Africa","authors":"Karel Kleisner, Šimon Pokorný, Viktor Černý","doi":"10.1007/s10508-026-03552-9","DOIUrl":"https://doi.org/10.1007/s10508-026-03552-9","url":null,"abstract":"In human faces, sexual dimorphism manifests itself in both morphological traits and skin color differences between males and females. Existing research has focused mainly on facial shape, but less is known about the interplay between dimorphism in facial structure and skin color, particularly in African populations. We investigated the degree of sexual dimorphism in facial shape and skin color in four sub-Saharan African populations (Cameroon, Mauritania, Senegal, and Sudan) using geometric morphometric analyses. We examined whether masculinization of facial morphology was consistently associated with darker skin tones, as would be expected given the influence of sex hormones on pigmentation, or whether this relationship varied across populations. Sexual dimorphism varied significantly in both shape and color across populations. The Sudan sample exhibited the strongest shape dimorphism in facial structure, while the Cameroonian and Mauritanian samples showed less pronounced differences. In contrast, the Senegal sample demonstrated the highest dimorphism in skin color, with men being notably darker than women. An unexpected pattern emerged in the Cameroonian and Mauritanian samples, where the most morphologically masculine men had a lighter skin than their less facially masculine peers. This challenges the expectation of skin darkening with increased masculinization. Given the drawbacks of highly masculine appearance, we discuss a possible compensatory mechanism where highly masculinized men have a lighter skin to offset the social or reproductive costs associated with morphological hypermasculinity. Our findings highlight the complexity of sexual dimorphism in African populations, emphasizing the need for further research into the impact of evolutionary, genetic, and sociocultural factors on facial diversity.","PeriodicalId":8327,"journal":{"name":"Archives of Sexual Behavior","volume":"12 1","pages":""},"PeriodicalIF":3.8,"publicationDate":"2026-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149360084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These approaches can produce very different prevalence estimates, making comparisons across studies difficult. Therefore, this study examined how these two criteria, self-identification versus practice frequency, differ in describing BDSM engagement, other sexual behaviors, and their sexual function, using a sample of self-identified BDSM practitioners and the general population. We analyzed data from 3904 Chilean adults who completed measures of sexual behaviors and sexual function, using the International Index of Erectile Function and Female Sexual Function Index. Results showed that practice frequency identified nearly twice as many BDSM practitioners as self-identification. Although the two criteria were positively correlated, the overlap was small. Compared with non-self-identified BDSM participants, individuals classified by practice frequency reported more frequent engagement in BDSM-specific activities, greater sexual pleasure from these practices, and, especially among high-frequency practitioners, better sexual function. In contrast, self-identification captured fewer practitioners and was less sensitive to differences in sexual behaviors and function, though it was associated with reduced reports of sexual pain among women. Overall, practice frequency provided a broader picture of BDSM engagement, while self-identification reflected a smaller, possibly more community-oriented group. These findings highlight the importance of considering both criteria when studying BDSM, as each captures distinct aspects of sexual identity and behavior. Using both approaches can improve the accuracy of prevalence estimates and deepen understanding of BDSM’s relationship to sexual health.</p></div>","PeriodicalId":8327,"journal":{"name":"Archives of Sexual Behavior","volume":"55 7","pages":"3237 - 3256"},"PeriodicalIF":2.6,"publicationDate":"2026-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149317373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A recent development is the proliferation of artificial intelligence (AI) image generators, which enable rapid, cost-effective, and highly customizable images with appealing aesthetics based on textual requests (prompts). To examine the opportunities and challenges of AI-generated images in SRHR communication, we used the topic of menstruation and developed six research questions (RQs) anchored in the current state of research on AI-supported visual health communication. These questions addressed key areas of concern, such as unsuccessful image creation (RQ1), objective image flaws (RQ2), lack of diversity of human representation (RQ3), stereotypical portrayals of women (RQ4), use of visual symbols (RQ5), and image valence (RQ6). Our study applied 15 AI image generators, 2 user accounts per generator, 5 menstruation-related prompts, 2 prompt languages, and 2 images per prompt, resulting in a sample of N = 600 AI outputs generated in Autumn 2025. All outputs were manually coded using a reliability-tested codebook developed through both deductive and inductive approaches. In 20.0% of cases, menstruation prompts did not produce the requested image but only text output (RQ1). When images were generated, they often (78.1%) exhibited visual and/or textual flaws (RQ2). The images showed a lack of diversity in some human attributes (e.g., body type) but not in others (e.g., skin tone; RQ3). Stereotypical depictions of women were observed but not predominant (RQ4). Common menstruation-related visual symbols (e.g., blood, pain) were identified (RQ5), but most images did not convey a negative portrayal and instead a neutral or positive portrayal of menstruation (RQ6). While results show that initial outputs from AI image generators are often not directly suitable for visual sexual health communication, they might work with targeted refinement. Further research is required to examine the production, characteristics, consumption, and effects of AI-generated images in SRHR communication.</p>","PeriodicalId":8327,"journal":{"name":"Archives of Sexual Behavior","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149332169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We examined 62 facial metrics extracted from face photos of 100 androphilic (i.e., sexually attracted to adult males) women, 100 gynephilic (i.e., sexually attracted to adult females) men, 100 <i>muxe nguiiu</i> (masculine-presenting androphilic males), and 100 <i>muxe gunaa</i> (feminine-presenting androphilic males). Multivariate analyses confirmed facial morphology differences across groups. Binary logistic regression models accurately predicted sex (81.5%), male sexual orientation (77.7%), and androphilic male gender identity/presentation (69.5%). In addition, a discriminant function analysis (DFA) successfully classified 69.8% of participants on the basis of their facial metrics. DFA revealed a masculinity–femininity continuum (Function 1: gynephilic men &gt; <i>muxe nguiiu</i> &gt; <i>muxe gunaa</i> ≈ androphilic women) alongside unexpected hyper-masculinization continuum (Function 2: <i>muxes</i> &gt; gynephilic men; <i>muxe gunaa</i> &gt; <i>muxe nguiiu</i>). Univariate partial correlations revealed significant associations between facial metrics and sex (29/62), male sexual orientation (26/62), and androphilic male gender identity/presentation (12/62), partially replicating Skorska et al.’s (2015) findings in relation to sex but not male sexual orientation. Integrating the univariate differences in facial metrics using multivariate analyses resulted in improved predictive accuracy for distinguishing among the four groups by sex, sexual orientation, and androphilic male gender identity/presentation. We discuss plausible biological mechanisms associated with the development of these traits. Our findings provide further evidence suggesting that associations between facial morphology, sex, and sexual orientation are present cross-culturally.</p></div>","PeriodicalId":8327,"journal":{"name":"Archives of Sexual Behavior","volume":"55 7","pages":"2929 - 2946"},"PeriodicalIF":2.6,"publicationDate":"2026-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149261076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
