P-1390. Anorectal Human Papillomavirus (HPV) Infection in HIV-Positive Men who have Sex with Men (MSM) in Nicaragua

Abstract Background HIV-positive men who have sex with men (MSM) are at increased risk for sexually transmitted infections, including anorectal HPV, with the consequent likelihood of neoplasia at that level. There is a complete lack of information on this situation in Nicaragua. This study explores and establishes for the first time the prevalence of anorectal HPV infection in HIV-positive MSM and its correlation with cytological abnormalities, and some associated behavioral, virological, and immunological factors in Nicaragua.Figure 1.Prevalence of HPV Anorectal Infection in MSM HIV Positive Diagnosed by RT-PCR Xpert HPV. Methods A prospective, multicenter cohort study was conducted between January 2023 at December 2023, at Dr. Fernando Vélez Paiz Hospital, Antonio Lenin Fonseca Hospital, and Manolo Morales Hospital in the city of Managua, Nicaragua. HIV-positive MSM patients were enrolled to the study with prior consent. Anorectal swab samples were processed by molecular method for HPV detection (GeneXpert HPV®) of different genotypes individually or grouped into genetic patterns (16, 18/45, P3: 31/32/35/52, P4: 51/59, and P5: 39/56/66/68). In addition, anorectal Pap smears were performed for cytopathology study. All samples were processed in the microbiology and pathology laboratories of the Dr. Fernando Vélez Paiz Hospital, the main center of the research.Figure 2.Different Genotypes Detected by Xpert HPV Anorectal Infection in MSM HIV Positive. Results A total of 44 patients were enrolled in the study. A significant proportion of patients declined to participate in the study. The mean age was 35.2 ± 12.4 years. Most of the patients reported having a passive or versatile sexual role. 22.7% were naïve to antiretroviral therapy (ART). The prevalence of anorectal HPV infection was 86.3% (Figure 1). The most frequent genotype was HPV 16 (21.7%) (Figure 2). In the combined genotype patterns, P3 (31/32/35/52) was observed in 40.5% of patients. All patients were infected with more than one genotype. 31.5% of those infected had cytological abnormalities, the most frequent being low-grade squamous intraepithelial lesion (Table 1). HPV-positive patients were younger, had a higher viral load, and a lower CD4+ lymphocyte count (Table 2).Table 1.Abnormalities in Anal Papanicolau in MSM HIV-positive con HPV Infection Diagnosed by Xpert HPV. Conclusion The prevalence of anorectal HPV infection in this study is high, with serotype 16 being the most frequent. Almost a third of them have altered cytology, with low-grade squamous intraepithelial lesion being the most frequent finding.Table 2.Differences in Age, HIV Viral Load and Count of Lymphocyte CD4+ in MSM HIV-Positive with and wihtout HPV Infection Disclosures All Authors: No reported disclosures

Rip Van Winkle in the Rainforest

Abstract This article reports on a several-week-long visit to Upper River Saamaka by two anthropologists who had been absent from the area for 45 years. They witnessed significant changes in transportation, communication, village layout, education, clothing, agriculture, ritual life, and sex roles. They also report on central government encroachment, illegal logging, Saamaka political resistance, and depopulation due to migration to the capital and to neighboring French Guiana.

Natural and sexual selection and functional roles influence colouration but not the amount of variation in butterfly wing colour patterns

BackgroundTrait variation is shaped by functional roles of traits and the strength and direction of selection acting on the traits. We hypothesized that in butterflies, sexually selected colouration is more variable owing to condition-dependent nature and directional selection on sexual ornaments, whereas naturally selected colouration may be less variable because of stabilising selection. We measured reflectance spectra, and extracted colour parameters, to compare the amount of variation in sexually versus naturally selected colour patches across wing surfaces and sexes of 20 butterfly species across 4 families (Nymphalidae, Papilionidae, Pieridae, Lycaenidae).ResultsWe found that: (a) males had more conspicuous, i.e., brighter and more saturated colour patches compared with females (as expected of sexually selected traits but not necessarily of naturally selected traits), and (b) dorsal surfaces in both sexes had more conspicuous sexual ornaments as well as protective (aposematic/mimetic) colour patches on darker wing backgrounds, compared with ventral surfaces. However, colour patches did not differ in the amount of variation either in selection (ecological/sexual functions), sex or wing surface-specific manner.ConclusionsThese findings show that functional roles and selection influence colour parameters but not the amount of variation in butterfly wing colour patterns.

Perception of the General Population About Sexual Activities in Later Life: A Cross-Cultural Perspective

Abstract Background: Cultural and societal norms could influence older age sexuality as societal sexual attitudes are shown to set the stage for how one adjusts to biological changes. Therefore, understanding cultural diversity and its association with public perception of sexuality in later life is warranted. Objectives: To explore the public’s perception of sexual activities in later life through a cross-cultural perspective to comparatively identify the elements of the people’s culture that are most associated with how the public views sex in later life. Materials and Methods: This was comparative research utilizing a cross-sectional online survey among the general population of Nigeria 79 (73.8%) and India 28 (26.1%) adults aged 18 years and above (n = 107; female = 54.2%). Data for the study were collected using an adapted questionnaire to elicit responses on the sociodemography of respondents and their perception of appropriateness, emotions, reactions, and thoughts about sexual activities among older people. Results: The findings consistently showed that what attitudes and perceptions the public/individuals have is a function of their prevailing culture as their ethnicity, nationality, and religious status mostly showed statistically significant relationships with their attitudes and perceptions (P < 0.05) showing the cultural sensitivity of human sexuality especially for older persons that are unmarried, widowed, and divorced. Conclusion: This study aligns with recent literature on the beneficial role of later-life sexuality and hereby creates awareness of the positive aspects of sexuality in later life and calls for social and medical support for the aged to access and receive sexual relations all through their later life.

The Intimate and Sexual Costs of Emotional Labor: The Development of the Women’s Sexual Emotional Labor Assessment

Emotional labor, the act of suppressing or altering one’s feelings to enhance another person’s well-being, is predominantly performed by women, especially within intimate relationships. Despite its impact on well-being, research on its role in sexuality remains limited. We developed the Women’s Sexual Emotional Labor Assessment (WOSELA), a 12-item scale based on themes identified by past qualitative studies. To ensure its reliability and validity, we conducted three studies with women partnered with men, as well as heterosexual single women from the UK and the USA (N = 831). Drawing on exploratory factor analysis in Study 1, four subscales were identified: faking orgasm, performing desire, tolerating discomfort or pain, and partner-referenced sexual satisfaction. Confirmatory factor analyses in Study 2 (pre-registered) provided support for the WOSELA in its current form. In Study 3 (pre-registered), we demonstrated the validity of the WOSELA by establishing significant negative correlations with sexual agency, sexual communication, and sexual pleasure. Our results further show that the WOSELA was not significantly related to positive-partner-oriented sexual responsiveness. The WOSELA offers a unique tool to explore the role of emotional labor in sustaining the pleasure gap, as well as in broader power dynamics within intimate relationships and its impact on women’s well-being.

The Rise and Assimilation of Western Queer Cinema: Resistance and Dilemma in the Mainstream

Queer cinema has risen to prominence in recent years, frequently featured at major international film festivals and gaining a foothold in the global market. As an extension of queer theory, which highlights the fluidity of gender and sexuality, queer cinema initially aimed to challenge traditional gender norms and heteronormativity through radical narrative structures and visual expressions. Early queer films often subverted mainstream narratives, offering an alternative, politically charged lens to explore marginalized identities. However, as queer cinema has increasingly entered the mainstream market, it has been subjected to assimilation and commodification pressures. This has led to a dilution of its radical and subversive elements, as the narratives are increasingly shaped to fit within heteronormative frameworks. Queer characters, once at the centre of challenging societal norms, are now often marginalized or simplified to meet the expectations of broader, more mainstream audiences. This paper examines how capitalism and patriarchy have contributed to the assimilation and marginalization of queer cinema, limiting its political expression and cultural impact. While Russo highlights how Hollywood perpetuates lazy stereotypes of queer characters, White suggests that cinema, as a tool of capitalist and patriarchal power, helps maintain normative gender and sexual roles. Despite these challenges, queer cinema remains an important cultural tool for breaking down stereotypes and resisting the dominance of heteronormativity. To maintain its relevance and continue its political and cultural resistance, queer cinema must resist commodification and strive for more diverse, authentic representations of queer identities.

CD4 Co-Receptor Regulates Sex-Specific NK Cell Responses to Acute Toxoplasma gondii Infection.

Immunity to Toxoplasma gondii ( T. gondii ) is sexually dimorphic in humans and mice, with females having higher morbidity and mortality during immune dysfunction and HIV-AIDS. The mechanisms underlying these sex differences are unclear. We investigated how a lack of CD4+ T cells (CD4 co-receptor KO) impacted T. gondii survival in mice. Female CD4 co-receptor KO mice succumbed to T. gondii much faster than males. To dissect why female CD4 co-receptor KO mice died faster, we tested their NK cell responses to acute T. gondii infection compared to males. Although in wild-type (WT) animals, both sexes had similar increases in total NK cells and IFNγ + NK cells, infected CD4 co-receptor KO female mice had 50% fewer IFNγ+ NK cells than infected WT female mice. Infected male CD4 co-receptor KO had a similar increase in IFNγ+ NK cells as WT male mice. Since CD4 co-receptor deficient mice still have functional helper T cells that are CD4-, we next tested survival and NK cell responses in female and male MHCII deficient (MHCIIKO) animals, which completely lack helper CD4+T cells. Surprisingly, survival, NK cell numbers, and IFNγ+ NK cells were not significantly different between WT or MHCIIKO female and male mice. These results suggest CD4 co-receptor expression is required for survival via optimal NK cell responses during acute T. gondii infection only in female mice and not in male mice. Our findings reveal an unappreciated sexual dimorphic role of CD4 co-receptor expression in regulating NK cell responses to acute T. gondii infection.

Intimate Partner Violence Experiences among Men Who Have Sex in Hanoi, Vietnam.

Intimate partner violence (IPV) victimization is a pressing issue among men who have sex with men (MSM) and has profound health implications. This study aims to estimate the prevalence of IPV and identify factors associated with its occurrence among MSM in Hanoi, Vietnam. A cross-sectional study was conducted from March to May 2023 at an MSM-friendly sexual health clinic in Hanoi. Participants completed a self-administered questionnaire on a tablet after screening for eligibility. IPV victimization was assessed using a 21-item scale (the IPV-GBM scale). Logistic regression models were used to identify factors associated with IPV victimization in the past 12 months. Among 309 respondents, the mean age was 28 and half of participants reported using PrEP for 12 months or more. Two-thirds reported IPV victimization in the past 12 months (67%). Emotional IPV (47%) was most prevalent, followed by monitoring (39%), controlling (19%), and physical/sexual IPV (15%). Participants who were reported experiencing IPV in the past 12 months were more likely to be aged ≤ 24 years (aOR = 1.98, 95% CI: 1.14, 3.44), to report preferring the insertive sexual role (aOR = 2.02, 95% CI: 1.10, 3.70), or to report having more sexual partners (2-5 partners vs ≤ 1 partner: aOR = 2.02, 95% CI: 1.10, 3.70; ≥ 5 partners vs. ≤ 1 partner: aOR = 2.02, 95% CI: 1.10, 3.70). IPV victimization among MSM on PrEP in Hanoi is highly prevalent. Tailored interventions are needed to address these vulnerabilities and promote safer behaviors and healthier relationships. Efforts should prioritize younger MSM. Further research is necessary to explore IPV dynamics across diverse settings.

The Forced-To-Penetrate Myth Acceptance Scale (FTP-MAS): A New Attitudinal Tool for Assessing Myths That Surround Female Perpetrated Sexual Violence Against Men.

The purpose of this study was to develop and validate a new measurement tool designed to capture endorsement of myths surrounding female perpetrated sexual violence against men, specifically in 'forced-to-penetrate' cases. Data were collected among a sample of 4152 UK adults aged 18-55+ (52% female). Dimensionality and construct validity of the Forced-to-Penetrate Myth Acceptance Scale (FTP-MAS) was investigated using traditional Confirmatory Factor Analysis (CFA) techniques separately for the complete sample, males only, and females only. CFA results indicated that FTP-MAS scores are best captured by a three-factor model (1. Distorted Sex and Gender Roles; 2. Harm Minimisation; 3. Offence Denial) across all samples tested. Excellent composite reliability and differential predictive validity were observed for all three subscales. The validated 22-item FTP-MAS constitutes the first measurement tool which allows for the assessment and evaluation of public attitudes towards female perpetrators who force men to penetrate them without consent. As such, this tool enables researchers to better understand the multi-faceted nature of these myths, assess prevalence in different contexts, and can also be used as an outcome measure in research seeking to evaluate the effectiveness of interventions that aim to debunk endorsement of such myths and stereotypes.

Revealing the dominant metacognitive activities of high school students in solving central tendency and dispersion problems based on gender

Research on the relationship between gender and metacognition in mathematical problem-solving has yielded inconsistent findings. Some studies suggest that gender influences metacognitive activities, while others report no significant differences. This study seeks to explore metacognitive activities during each stage of statistical problem-solving among two 12th-grade students with contrasting gender expressions: a feminine-expressing female and a masculine-expressing male. The instruments utilized in this research include the Bem Sex Role Inventory (BSRI) gender questionnaire, a mathematical ability test, a statistical problem-solving task, and an interview guide. Data collection was conducted in two phases: the BSRI questionnaire and mathematical ability test were used to classify participants, followed by problem-solving tasks and semi-structured interviews to capture their metacognitive processes. Employing a descriptive exploratory design with a qualitative approach, the study applied thematic analysis to organize and interpret data from task performance and interview transcripts. These findings were further synthesized into hierarchical diagrams to illustrate the dominance of metacognitive components at different problem-solving stages. Results indicate that the feminine-expressing female predominantly utilized metacognitive knowledge, specifically declarative knowledge, during the problem-understanding phase. In contrast, the masculine-expressing male demonstrated more reliance on metacognitive regulation, particularly in planning and monitoring, during the problem-implementation stage. These findings underscore the importance of developing inclusive curricula and differentiated teaching strategies to enhance metacognitive skills across diverse student populations.

Bisexuality among Men who have Sex with Men in Sub-Saharan Africa: Findings from the HPTN 075 Study.

Studies among men who have sex with men (MSM) in sub-Saharan Africa (SSA) focus mainly on HIV epidemiology, revealing little about the diversity within this population. We utilized data from the HIV Prevention Trials Network (HPTN) 075 study, to explore demographic and psychosexual characteristics of MSM in SSA who also have sex with women. Persons included in the analyses were aged 18-44 years and assigned male sex at birth and identified as male, reported anal sex with a man in the past 3 months, and had enrolled at one of four study sites (Kisumu, Kenya; Blantyre, Malawi; Cape Town and Soweto, South Africa). Nearly a quarter of the participants had recently engaged in sex with both men and women (MSMW). These men differed in terms of demographic and psychosexual characteristics, and sexual behavior from men who only had had sex with men (MSME). Compared to the latter, MSMW were more likely to prefer the insertive sexual role, reported more sexual partners in the past three months, and had more instances of condomless insertive anal intercourse with a man. These findings suggest that men who have sex with both men and women have specific characteristics and need tailored interventions that take their specific needs into account.

Is Being Male a Marker of Aggression? Evidence for the Decoupling of Sex and Gender Role Orientation.

This study explores whether sex differences in reactive aggression (RA) and proactive aggression (PA) are attributable to sex, gender role orientation, or their interaction and explores the neuroanatomical characteristics of these sex differences. In a sample of 108 males and 126 females, we examined the sex-by-gender role orientation interaction on RA, PA, and brain gray matter volume (GMV). Then, we explored the relationship between aggression and regional GMV. When the effects of sex and gender role orientation on aggression were disentangled, there were no sex differences in RA, regardless of gender role orientation. However, sex differences (male > female) in PA were observed within the masculine group but not within the feminine group. Brain imaging results revealed sex differences (male > female) on the right inferior frontal gyrus GMV, a region involved in cognitive control, within the masculine group. Moreover, a negative association between PA and the right inferior frontal gyrus GMV was observed in masculine females rather than masculine males. These findings indicate that gender role orientation has a more significant effect on aggression than sex, particularly with regard to PA, and hint that the goal of cognitive control involved in displaying PA differs in masculine males and masculine females.

Identification of Research Trends Related to Marriage Values Using Keyword Network Analysis

The purpose of this study was to analyze research trends related to marriage values using keyword network analysis. To this end, 157 dissertations and academic journal papers related to marriage values published in Korea from 2001 to April 2024, along with 247 keywords were selected for analysis. Keyword network analysis was applied to the selected keywords using Microsoft Excel 365 and NetMiner 4.0. The results were as follows. First, research related to marriage values was low for the 10 years starting in 2001; however, the number of research materials gradually increased in the 2010s, and then increased significantly from the late 2010s. The 30 keywords that appeared most frequently were related to various personal psychological and socio-cultural variables that influence marriage values, and the keyword that appeared most frequently was 'family values'. Second, an analysis of keyword network centrality revealed that 'marriage intent' appeared in the connection centrality, 'sex role values' appeared in the proximity centrality, and 'generation' appeared in the mediation centrality. In terms of the overall centrality, 'child value' also exerted a relatively high influence. By identifying the various variables that affect marriage values, this study provides a wealth of information useful for the development of educational programs aimed at forming marriage values among adolescents, college students, unmarried men and women, prospective couples, prospective parents, and parents.

Features influencing surface acting of different clusters of nursing students in vocational college based on interpretable machine learning: A cross-sectional study

AimTo explore and explain the mechanisms that influence surface acting in nursing students with different characteristics. BackgroundNurses are now expected to deliver patient-centered care which necessitates the emotional labor. Surface acting, a form of emotional labor, can lead to negative outcomes. Given that nursing students are the backbone of the future nursing profession, there is an urgent need to investigate their surface acting tendencies and identify potential factors for early intervention. DesignA cross-sectional study. MethodsThis study was surveyed in a vocational college in Gansu, China. Participants completed the general information questionnaire, Bem Sex Role Inventory, Professional Identity Questionnaire of Nursing Students and Surface Acting Scale. K-means cluster analysis was performed, followed by random forest algorithm and SHapley Additive exPlanations based on Python program. ResultsA total of 1241 nursing students from vocational college were investigated and were clustered into 4 groups. The five dimensions of professional identity had higher feature importance in all four groups, with professional self-image having the highest feature importance in Cluster 3. Professional self-image and understanding retention benefits and turnover risks were negative predictors of surface acting in all four groups. Social comparison and self-reflection, independence of career choice and social modeling regarding nursing profession were positively correlated with surface acting in specific groups. In Cluster 1, there exists a positive correlation between professional self-image and the constructs of social comparison and self-reflection; as well as a negative correlation between maternal education and understanding of retention benefits and turnover risks. ConclusionsProfessional identity significantly influences surface acting behaviors among nursing students, with professional self-image serving as a key negative predictor. Positive family conditions, access to educational resources, parental literacy, masculine or feminine gender roles and first-year nursing students, these traits have implications when dimensions of professional identity are used to predict surface acting behaviors.

Sex versus gender associations with depressive symptom trajectories over 24 months in first-episode schizophrenia spectrum disorders

BackgroundFemales with schizophrenia often experience more severe and persistent depressive symptoms than males, in particular during the acute phase of the illness. In contrast to sex (a biological distinction), little is known about the associations between gender (a societal construct) and depression in schizophrenia. AimWe examined the associations of sex versus gender with visit-wise changes in depressive symptoms over 24 months in patients with first-episode schizophrenia spectrum disorders (FES) (n = 77) compared to matched healthy controls (n = 64). MethodsThe Bem Sex Role Inventory was used to measure feminine gender role endorsement. The Calgary Depression Scale for Schizophrenia was used to measure depressive symptoms at baseline, weeks 2, 4, and 6, and months 3, 6, 9, 12, 15, 18, 21, and 24. We used mixed models for continuous repeated measures to examine the moderating effects of childhood trauma, premorbid adjustment, age of psychosis onset, and cannabis use on the associations of sex and gender with depressive symptoms. ResultsHigher feminine gender role endorsement, independent of biological sex, was associated with more severe baseline depression and worse initial treatment trajectories. Childhood trauma exposure was also associated with worse depression outcomes, and mediated the association between gender and pre-treatment depression severities. ConclusionsGender, but not sex, was associated with depressive symptom trajectories in FES. The consideration of both sex and gender offered a more nuanced insight into depressive symptoms compared to biological sex alone.

MAPPING THE FEMVERTISING LANDSCAPE: A SYSTEMATIC LITERATURE REVIEW

In this systematic literature review, the aim is to explore the place of the concept of femvertising in academic literature. Accordingly, articles published in journals indexed in the Web of Science database that use the keyword "femvertising" have been analyzed. The results revealed that research on femvertising has been conducted since 2016, with most studies focusing on the business category. More than half of the articles have employed qualitative research methods. The review of contemporary literature reveals a growing body of research centered around the concept of femvertising, with a particular emphasis on the interplay between social media, women empowerment, and consumer attitudes. A notable gap in the existing literature is the paucity of studies investigating the intersection of femvertising and corporate social responsibility. After the VOSviewer analysis, the most frequently cited sources are revealed as the Journal of Advertising, International Journal of Advertising, Female Media Studies, and Sex Roles. The presence of Female Media Studies and Sex Roles emphasizes the interdisciplinary aspect of femvertising research, thus suggesting that a comprehensive understanding of the topic requires perspectives from both marketing and gender studies. This underscores femvertising's relevance in both fields. Also, the analyzed articles mainly used qualitative methods, with content analysis, interviews, discourse analysis, and textual analysis being the most common. Quantitative methods like experiments and structural equation modeling were also used, though studies combining both approaches were rare. There is a notable deficiency in research employing big data analytics.

Form And Meaning of Javanese Woman’s Masculinity in Joko Anwar’s “Perempuan Tanah Jahanam” (2019)

This research aims to find out the form and meaning of Javanese women’s resistance of NyiMisni, a Javanese woman character in the film entitled “Perempuan Tanah Jahanam” (2019), and how her masculinity is reflected through the interaction between her and other characters in the film. The analysis is conducted in the context of patriarchal domination over Javanese women specifically, and Indonesian women in general. The main data is obtained from the dialog uttered by the main female character, NyiMisni, in Joko Anwar’s “Perempuan Tanah Jahanam” (2019) film. It is supported by secondary data from other articles that mentioned masculinity traits shown by Javanese female characters in other films. The method of collecting data used in this research is the observation method using an observation technique. The techniques conducted are watching the movie, note-taking all dialogues that contain masculinity features, and classifying the data based on the masculinity features shown by NyiMisni. The analysis is conducted using Bem’s Sex Role Inventory (1982) and the theory of symbolic interactionism by Smelser (2013. Furthermore, the speech act theory by Searle (1976) is used as the supporting theory. The findings discovered some forms and meanings of Javanese women’s resistance as the masculinity features shown by NyiMisni and how she interacts with other participants through her utterances. Female masculinity is featured in assertiveness, dominance, and aggression. Her utterance is directly conducted, yet the intention is indirect.

Hospital policies as a tool to reduce gaps between ethnic groups of employees and patients

Abstract Background As diverse organizations, hospitals require an inclusive culture that respects and promotes ethnic diversity. Violence, a threat to this diversity, hampers effective organizational functioning. Our study delves into the positive influence of cultural diversity policies and communication about violence on the perception of the hospital’s atmosphere regarding ethnic differences among health employees. It enhances hospital labor relations and mitigates the risk of workplace violence. Methods 372 hospital employees with an average tenure of 6.5 and an average age of 38 filled out an online close-ended questionnaire (83% are Israeli Jews, 68% are female). 91% report working closely with people from different ethnic origins. Respondents ranked the atmosphere in the hospital regarding ethnic differences between employees and patients, the hospital’s cultural diversity policy, and organizational communication about violence. Data were analyzed by SPSS 28. Results Positive correlations were found between variables. A positive atmosphere was significantly related to the hospital’s cultural diversity policy (r=.14, p=.002) and to organizational communication about violence (r=.22, p< .001). However, the regression analysis (with control variables age, sex, and managerial role) revealed that despite employees acknowledging the hospital’s efforts to address diversity and violence, these factors only predict 10% of the variance of the hospital atmosphere [F(5, 366) = 8.346, p < .001; R²=.10]. Conclusions The hospital should increase actions that will improve the ethnic atmosphere in the hospital. Understanding how the encounter, where employees and patients from diverse ethnic backgrounds interact, influences the hospital’s atmosphere is crucial. These interactions can lead to tensions and offensive behaviors toward employees if not managed well. Hospitals can create an inclusive and harmonious work environment by addressing these tensions. Key messages • A cultural diversity policy and communication are necessary to maintain harmonious working relationships. It is essential, particularly in health organizations characterized by ethnic diversity. • Reducing the perception of ethnic differences may increase well-being and decrease violence. While hospitals often don’t prioritize these issues, this study forefront their influence and importance.

Anisogamy and sex roles: a commentary.

The origin and maintenance of sex differences in reproductive behavior (often labeled sex roles) have remained controversial topics, and recent meta-analyses and theoretical models have helped to elucidate the processes that generate diverse sex roles. We are glad to see that our study (Mokos et al., 2021) generated a healthy debate, and in agreement with recent commentaries (Janicke, 2024; Lehtonen & Parker, 2024) we call for a more comprehensive approach to understanding sex role evolution.
