Early developmental masculinization among boys: More prenatal testosterone action (assessed via 2D:4D) renders their faces perceived as masculine but not pretty or cute.

The 'organizational-activational hypothesis' posits that the fetal environment has a lasting impact on offspring physical, cognitive, and behavioral phenotype. An established biomarker for human prenatal testosterone exposure is the second-to-fourth digit ratio (2D:4D). While related facial characteristics and their social perceptions have been investigated in young adults, studies focusing on younger or older age groups are scarce. Standardized facial photographs of 17 Austrian boys aged 4 to 11 years were each rated by 162 adults in Austria (78 female, 84 male) for masculinity, dominance, physical strength, maturity, independence, cuteness, and prettiness. Following high interrater agreement (Cronbach's alphas >0.96), average ratings per face were subjected to a principal component analysis. The first principal component (52 % var. expl.) correlated positively with the boys' age (r = 0.685), whereas the second principal component (37 % var. expl.) reflected organizational effects of prenatal androgen exposure (i.e. androgenization), as shown by a negative correlation with the boys' 2D:4D (r = -0.487). Geometric morphometrics was employed to extract the facial shapes corresponding to these two principal components. Overall, adults consistently attributed masculinity in line with prenatal testosterone exposure, whereby masculinity was assessed as neither pretty nor cute. In contrast to findings within adults, boys' face ratings of dominance and physical strength did not correspond with their masculinity assessments, but rather with the social attributions reflecting age-related developmental progress (maturity and independence). This adds an ontogenetic layer of complexity. Prenatal testosterone exposure influences the development of boys' facial features, which in turn even shape social stereotypes in adults.

Negotiating Hegemonic Masculinities and Mutual Exoticization within Grindr Tourism Interactions: "Everyone in Tel Aviv is a Muscle God".

Dating apps are spaces where masculinities are communicated digitally, affecting inequalities around gender expressions. This study aims to identify the masculinities communicated within Grindr tourism interactions in Tel Aviv and analyze how masculinities shape relations among international tourists and locals. Methods consist of interviews and audio diaries with nineteen tourist, local, and immigrant Grindr users in Tel Aviv. Theories of affordances, hegemonic masculinities, and relational sociology are used to analyze the data. In discussion of the results, the concept of mutual exoticization is put forth to interpret the social dynamics valued within Grindr tourism interactions, thereby revealing oppositional fantasies tied to nationalities and masculinities. The study also explores ethnicity's association with social and erotic capital in digital circulations of a localized Mizrahi masculinity. Findings reveal that while hegemonic masculinities are circulated on Grindr, resistance is also a part of Grindr tourism relations around masculinities. This research concludes by shedding light on masculinity inequalities within digital spaces where different nationalities co-congregate, revealing everyday negotiations of gender regimes. Grindr is the site of both reproduction of and resistance to social inequalities around masculinities.

Reflexivity and positionality applied to medical practice: a study on implicit gender bias with medical students in a Swiss university.

BACKGROUND: An array of evidence shows how the presence of implicit bias in clinical encounters can negatively impact provider-patient communication, quality of care and ultimately contribute to health inequities. Reflexive practice has been explored as an approach to identify and address implicit bias in healthcare providers, including medical students. At the Lausanne School of Medicine, a clinically integrated module was introduced in 2019 to raise students' awareness of gender bias in medical practice using a reflexivity and positionality approach. The purpose of this study is to describe the gender bias that were identified by medical students, analysing their types, places and modes of emergence during a clinical encounter. It further explores how positionality supported students' reflection on the way in which social position modulates their relationship to patients. METHODS: As part of the teaching activity, medical students individually reflected on gender bias in a specific clinical encounter by answering questions in their electronic portfolio. The questionnaire included a section on positionality. We qualitatively analysed the students' assignments (n=76), applying a thematic analysis framework. RESULTS: Medical students identified and described gender biases occurring at different moments of the clinical encounter (anamnesis (i.e. patient history), physical exam, differential diagnosis, final management). They causally associated these biases with wider social phenomena such as the gendered division of labour or stereotypes around sexuality and gender. Analysing students' reflections on how their position influenced their relationship with patients, we found that the suggested exercise revealed a major contradiction in the process of medical enculturation: the injunction to be neutral and objective erases the social and cultural context of patients and impedes an understanding of gender bias. CONCLUSION: Gender biases are present in the different steps of a clinical consultation and are rooted in broader gendered social representations. We further conclude that the tension between a quest for objectivity and the reality of social encounters should be made explicit to students, because it is constitutive of medical practice.

Fathers' experiences with supportive parenting interventions: A qualitative systematic review.

Despite proven efficacy, fatherhood interventions face challenges in attracting and retaining participants. This qualitative systematic review aims to inform the future design of fatherhood interventions by consolidating and synthesizing the evidence around fathers' experiences with interventions aimed at enhancing their involvement and relationships with their children. Following PRISMA guidelines, we analyzed 10 studies from a search of six electronic databases. Our analysis coalesced into three pivotal themes: (a) creating a sense of belonging: facilitating participation; (b) transformative takeaways; and (c) challenges of negotiating expectations of masculinity. Our findings indicate that group-based, culturally sensitive programs are advantageous but also reveal that fathers grapple with reconciling evolving fatherhood roles with societally entrenched expectations of masculinity. This review offers actionable insights for the future development, evaluation, and implementation of fatherhood interventions, particularly those utilizing qualitative research methodologies.

Understanding Public Perceptions of Nipple and Scar Characteristics After Chest Wall Masculinization Surgery.

BACKGROUND: Surgical chest masculinization procedures, especially gender-affirming top surgery (GATS), are becoming increasingly prevalent in the USA. While a variety of surgical techniques have been established as both safe and effective, there is limited research examining ideal aesthetic nipple appearance and incision scar pattern. This study employs patient images to understand the public's perception on top surgery outcomes when adjusting for BMI ranges and Fitzpatrick skin types. METHODS: Images from RealSelf modified via Adobe Photoshop depicted various scar types and nipple-areolar complex (NAC) sizes/positions. A Qualtrics survey was distributed utilizing Amazon Mechanical Turk. Statistical analysis was performed through JMP Pro 17 for ordinal and categorical values, with a p value less than or equal to 0.05 statistically significant. RESULTS: A moderately sized and laterally placed NAC was preferred. A transverse scar that resembles the pectoral border between the level of the inframammary fold and pectoral insertion was deemed most masculine and aesthetic. Majority of results demonstrated that this is unaffected by Fitzpatrick skin types. Increased BMI images impacted public preferences, as a nipple placed farther from the transverse incision (p = 0.04) and a transverse scar position closer to the IMF was preferred in higher BMI patients. CONCLUSIONS: An understanding of the most popular NAC and scar choices, as well as how these factors may differ when considering a Fitzpatrick skin type or BMI categorization was attained. This validates the importance of patient-centered approach when employing surgical techniques in GATS. Future studies intend to obtain reports from actual patients considering GATS. NO LEVEL ASSIGNED: This journal requires that authors assign a level of evidence to each submission to which Evidence-Based Medicine rankings are applicable.

Adolescent boys' aggressive responses to perceived threats to their gender typicality.

When adult men are made to feel gender-atypical, they often lash out with aggression, particularly when they are pressured (vs. autonomously motivated) to be gender-typical. Here, we examined the development of this phenomenon. Specifically, we provided a first experimental test of whether threatening adolescent boys' perceived gender typicality elicits aggression as a function of their pressured (vs. autonomous) motivation to be gender-typical. We also investigated whether this causal link emerges as a function of boys' chronological age versus pubertal development. Participants were a geographically diverse sample of 207 adolescent US boys (ages 10-14; 23.2% boys of color) and one of their parents. Boys played a "game" and received randomly-assigned feedback that their score was atypical versus typical of their gender. For boys in mid-to-late puberty (but not before), feedback that they are gender-atypical predicted an aggressive reaction, particularly among boys whose motivation to be gender-typical was pressured (vs. autonomous). Next, we explored which aspects of boys' social environments predicted their pressured motivation to be gender-typical. Boys' pressured motivation was positively correlated with their perceptions that their parents and peers would be "upset" if they deviated from gender norms, as well as with their parents' endorsement of so-called hegemonic beliefs about masculinity (i.e., that men should hold power over women). Parents with these beliefs resided in more conservative areas, had less formal education, and had lower incomes. Our results inform theorizing on gender identity development and lay the foundation for mitigating the harmful effects of gender typicality threat among adult men. RESEARCH HIGHLIGHTS: Similar to young adult men, adolescent boys in mid-to-late puberty (but not before) responded with aggression to perceived threats to their gender typicality. Aggression was heightened among boys whose motivation to be gender-typical was pressured (i.e., driven by social expectations) rather than autonomous. Which boys showed pressured motivation? Those whose parents endorsed hegemonic beliefs about masculinity (e.g., that men should have more power than people of other genders). Hegemonic beliefs about masculinity were strongest among parents who resided in more conservative US counties, had less formal education, and had lower incomes.

Assessing age invariance of the Male Depression Risk Scale-22 in younger and older adult males.

OBJECTIVES: Women are twice as likely to be diagnosed with major depressive disorder as men. Yet suicide rates are four times higher in men than women, increasing to six times when comparing older men to older women. Investigators have begun researching if depression presents differently in individuals who adhere to masculine norms, leading to the conceptualization of masculine depression. Despite validity evidence for the Male Depression Risk Scale-22 (MDRS-22) in mixed-age samples, few studies have investigated the possibility of age-related differences in masculine depression. The present study aimed to test for age invariance of the MDRS-22. METHOD: Age invariance for the MDRS-22 was tested via a multi-group confirmatory factor analysis with groups of younger (18-64 years) and older (65+ years) males (N = 469). RESULTS: Age invariance for the MDRS-22 was not established, ΔX2 = 451.47, Δdf = 16, p < 0.001. CONCLUSION: Results of the study indicate that masculine depression may present differently between younger and older men. To fully understand the construct of masculine depression, it is important to investigate how symptoms may present in individuals of all ages. Overall, the study highlights the importance of investigating how masculine depression may present differently in older men.

Masculinity stigma and metastatic prostate cancer: A review with a focus on Latin America.

BACKGROUND: This review examines the impact of masculinity stigma on the diagnosis and treatment of metastatic prostate cancer, particularly in Latin America. It aims to provide insights into the influence of masculinity stigma on patient outcomes and inform strategies to address this issue. METHODS: A comprehensive search was conducted in electronic databases (PubMed, PsycINFO, CINAHL and LILACS) using relevant keywords and controlled vocabulary related to metastatic prostate cancer, masculinity, stigma, diagnosis, and treatment up to April 2023. The search strategy was developed in consultation with a medical librarian to ensure its comprehensiveness. Thirty-three studies that investigate the role of masculinity stigma in the diagnosis and treatment of metastatic prostate cancer were included. RESULTS: Our findings highlight the unique sociocultural influences in Latin America that shape prostate cancer stigma. It emphasizes the impact of cultural beliefs, gender norms, and social expectations on stigma. Notions of masculinity, such as strength and invulnerability, contribute to the stigmatization of prostate cancer. Machismo culture and religious/spiritual beliefs further compound the challenges and hinder open communication about the disease. Cultural taboos, limited awareness, and misconceptions perpetuate the stigma. CONCLUSIONS: These sociocultural factors shape the experiences and challenges faced by individuals with and at risk of prostate cancer in Latin America.

Re-evaluating the Role of Partnership-Related Perceptions in Women's Preferences for Men with Masculine Face Shapes.

Many researchers have proposed that women perceive men with masculine face shapes to be less suitable as parents and long-term partners than men with feminine face shapes, causing women to find masculine men more attractive for short-term than long-term relationships. However, recent work shows that results obtained using the type of experimentally manipulated stimuli that were employed in studies presenting evidence for these claims are not necessarily observed when natural (i.e., unmanipulated) face stimuli were used to suggest that the evidence for these claims may need to be revaluated. Consequently, we tested for possible relationships between ratings of natural male faces for parenting- and relationship-related traits and shape masculinity (Study 1) and also tested whether women's preferences for shape masculinity were stronger when natural male faces were rated for short-term relationships than when natural male faces were rated for long-term relationships (Studies 2 and 3). We saw no evidence for either of these predictions, instead finding that men with more attractive faces were perceived to be better parents and better long-term partners. Thus, our findings do not support the widely held view that masculine men are more attractive for short-term relationships because they are perceived to be unlikely to invest time and effort in their romantic partners and offspring.

Understanding the Meat-Masculinity Link: Traditional and Non-Traditional Masculine Norms Predicting Men's Meat Consumption.

Conformity to masculinity ideology predicts men's meat consumption and willingness to reduce their meat intake, but it is unknown which specific masculine norms account for these relationships. This study investigated which traditional and non-traditional masculine norms predict meat consumption, red and processed meat consumption, and willingness to reduce meat consumption in 557 Australian and English males. Men who support the use of physical violence and place high importance on sex ate more meat. Willingness to reduce was highest among men with gender egalitarian views. Targeting these specific masculine norms may be important for mitigating men's overconsumption of meat.

Relationships between Grey Matter Volume in the Bilateral Superior Frontal Gyrus and Reactive Aggression Varied by Level of Traditional Masculinity.

Although previous behavioral studies have associated reactive aggression (RA) and proactive aggression (PA) with traditional masculinity, further investigation is needed into the traditional masculinity-linked neuroanatomical characteristics of RA and PA. This study analyzed the traditional masculinity-by-aggression interaction in 705 participants (350 men) by measuring grey matter volume (GMV). We have expanded on previous studies and found that traditional masculinity was not associated with RA and PA when not controlled for traditional femininity. However, the association appeared when controlling for it. Furthermore, we found significant traditional masculinity-by-RA interactions on the GMV in the bilateral superior frontal gyrus, a region known to be involved in cognitive control. When traditional masculinity scores were 1 standard deviation above the mean, there was a positive correlation between RA and the GMV in the bilateral superior frontal gyrus. Conversely, when traditional masculinity scores were 1 standard deviation below the mean, there was a negative correlation between RA and the GMV in the region. However, no traditional masculinity-linked neuroanatomical characteristics of PA were found. The results indicated that individuals with high/low traditional masculinity perceived RA as a different outcome (gain or loss) of self-control. The results supported an opportunity to develop prevention or intervention strategies for RA.

'My sexual desires, everything, my normal life just stops'; a qualitative study of male sexual health in inflammatory bowel disease.

AIM: To describe and interpret the sexual health experiences of men with IBD. DESIGN: Interpretive qualitative study. METHODS: In-depth, semi-structured interviews were conducted with 22 men with a diagnosis of Inflammatory Bowel Disease. Interviews were digitally audio-recorded and transcribed verbatim. Data were analysed using constant comparative, thematic analysis. RESULTS: Three themes were identified from interview data: (1) the disease shapes intimate connections, (2) the disease thwarts sexual experiences and (3) the disease disrupts male gender norms. Men reported that active disease lowered libido and could change pre-, inter- and post-coital sexual practices. All participants noted that health professionals did not initiate the discussion of sexual health and well-being needs in the outpatient hospital setting. Men who engaged in receptive anal sex reported a lack of disease-specific guidance and understanding from professionals. CONCLUSION: Inflammatory bowel disease can negatively impact the sexual well-being, gender identity and activities of men. Further research is required to identify the care preferences of men with IBD and clarify the barriers and facilitators to sexual health assessment so that nurses may better support the health needs of this population. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE: This study highlights the need for sexual health and well-being support that is specific to disease and gender in IBD. There is a paucity of information and guidance for men with peri-anal disease and proctitis who engage in receptive anal sex, which requires urgent attention. REPORTING METHOD: Reporting follows the COREQ checklist. PATIENT OR PUBLIC CONTRIBUTION: A patient and public involvement group informed the development of the study design. The group reviewed public facing documents and interview guides. One member of the group provided comments on the identified themes.

Hostile Masculinity, Male Peer Support for Violence, and Problematic Anger: Linking Childhood Abuse to Men's Partner Violence Perpetration.

Child abuse and masculinity have been linked to intimate partner violence (IPV) perpetration. However, there is a lack of work examining multiple aspects of masculinity as links between early abuse experiences and men's IPV perpetration. Grounded in notions of gendered power and patriarchy, this study aimed to examine hostile masculinity, male peer support for violence against women, and problematic anger as aspects of masculinity connecting childhood victimization and men's violence against women. Structural equation modeling results demonstrated that childhood adversity was indirectly related to IPV perpetration via the proposed factors. However, various patterns emerged based on the type of childhood abuse experienced. Practice-based implications are offered.

The lived experience of South African men having a premature baby.

Background: Much has been written about fathers, fatherhood and premature babies. However, in the South African context, studies about the experiences of fathers having a premature baby are lacking. Aim: This study aimed to explore how South African fathers (n = 10) experience having a premature baby using a descriptive phenomenological approach. Setting: This research study was conducted online using various social media platforms such as WhatsApp, Google Meet and through telephonic conversations. Methods: A descriptive phenomenological approach that allowed for the distillation and elucidation of common core experiences among fathers who had a premature baby. Results: The findings demonstrated that the participants experienced intense fears regarding the survival and well-being of their children. They reported experiencing financial difficulties related to hospital bills and experienced being alienated by hospital institutions. Despite these reported barriers, these fathers were adamant in their resolve to support their children and partners during this challenging time. Conclusion: The experiences of fathers were riddled with fear, uncertainty, ambiguity and alienation, which placed them in very precarious situations when trying to navigate their role in a more sensitive and enlightened way. Having a premature infant calls into question the systems that men are positioned within as these systems to a large extent shape these events and how they are experienced. Contribution: This study is original as no other published studies seem to exist in South Africa that speaks to fathers' lived experiences of having a premature baby.

Honor Endorsement and Increased Firearm Purchasing Behavior and Intentions During the COVID-19 Pandemic.

The surge in firearm sales from the onset of the COVID-19 pandemic have been linked to increases in firearm violence, which is of public concern given that having firearms in one's home is associated with increased risk for domestic violence and suicide. Consistent with pre-pandemic trends, individuals tended to purchase firearms for self-protection during COVID-19. Prior work indicates that protective firearm ownership is motivated not only by perceptions that the world (and one's local environment) is dangerous, but also by one's endorsement of masculinity norms found in U.S. cultures of honor (primarily southern and western states). Honor-based masculinity norms emphasis reputation defense, toughness, and an absolute intolerance of disrespect. The present research examined the relative motivating influences of various threat perceptions and masculine honor endorsement in predicting reasons for non-COVID-19 firearm ownership, firearm purchasing during COVID-19, and purchase intentions. Three separate samples (total N = 2483) of mostly White U.S. men completed online surveys during different months of the first year of the COVID-19 pandemic. Participants completed measures of their endorsement of masculine honor norms, factors associated with firearm purchasing (e.g., dangerous world beliefs, intolerance of uncertainty), and firearm purchasing behaviors. Results indicated that masculine honor endorsement was higher among (1) protective firearm owners compared to non-owners and non-protective owners, (2) firearm owners who purchased a firearm during COVID-19 compared to non-owners and non-purchasing owners, and (3) firearm owners with intentions to purchase firearms in the next year compared to those without intentions and undecided owners. Relative to other predictors (e.g., COVID-19 concerns, dangerous world beliefs), masculine honor endorsement was consistently the strongest predictor of these outcomes. Findings add to the literature by highlighting the strength of masculine honor endorsement in motivating (protective) firearm ownership. Implications for interpersonal violence and suicide are discussed.

Developmental Trajectories Leading to Hostility Toward Women: A Structural Equation Modeling Study.

Hostility toward women is frequently examined as a risk factor for violence against women, but research on its antecedents is sparse. The aim of this study was to explore the developmental and psychological antecedents associated with hostility toward women in a Canadian sample of sexual aggressors of women. Drawing on Malamuth's confluence model of sexual aggression, we developed a multifactorial model of hostility toward women, using structural equation modeling. The results indicate the presence of three trajectories, all starting from childhood victimization and leading to hostility toward women, involving antisocial characteristics, emotional negativity, anxiety, and depression.

Men's peer support for mental health challenges: future directions for research and practice.

Peer support has a long history of helping people navigate mental health challenges and is increasingly utilized within men's mental health promotion initiatives. Despite considerable research conceptualizing and evaluating peer support in various contexts, little is known about the gendered dimensions of men's peer support and mutual help for mental health. This article provides an empirically informed commentary on men's peer support and informal help-seeking preferences to make recommendations for future directions for research and practice. Research examining men's peer support is emergent and the available evidence suggests that there is potential to conceptually align with many men's values and preferences for mental health help-seeking. Peer support offers a non-clinical, strength-based adjunct to professional support that may aid men in navigating a range of mental health challenges. Consideration must be given to the influence of gender socialization and men's diverse experiences with developing and maintaining peer relationships. It should not be assumed that authentic and supportive relationships will naturally form when men congregate together. As a growing number of interventions and programs emerge targeted at boys and men, there are important opportunities to leverage these health promotion efforts to encourage and coach men to engage in mutual help. Opportunities for research and practice are discussed to better understand and harness the health-promoting potential of peer support for men's mental health.

Size Matters? Penis Dissatisfaction and Gun Ownership in America.

In this study, we formally examine the association between penis size dissatisfaction and gun ownership in America. The primary hypothesis, derived from the psychosexual theory of gun ownership, asserts that men who are more dissatisfied with the size of their penises will be more likely to personally own guns. To test this hypothesis, we used data collected from the 2023 Masculinity, Sexual Health, and Politics (MSHAP) survey, a national probability sample of 1,840 men, and regression analyses to model personal gun ownership as a function of penis size dissatisfaction, experiences with penis enlargement, social desirability, masculinity, body mass, mental health, and a range of sociodemographic characteristics. We find that men who are more dissatisfied with the size of their penises are less likely to personally own guns across outcomes, including any gun ownership, military-style rifle ownership, and total number of guns owned. The inverse association between penis size dissatisfaction and gun ownership is linear; however, the association is weakest among men ages 60 and older. With these findings in mind, we failed to observe any differences in personal gun ownership between men who have and have not attempted penis enlargement. To our knowledge, this is the first study to formally examine the association between penis size and personal gun ownership in America. Our findings fail to support the psychosexual theory of gun ownership. Alternative theories are posited for the apparent inverse association between penis size dissatisfaction and personal gun ownership, including higher levels of testosterone and constructionist explanations.

Social Perceptions of Masculinity and Sexual Esteem Are Impacted by Viagra Use, Testosterone, and Sexual Performance.

Sexual behaviors play a role in the social construction of masculinity. Moreover, this stereotype has been capitalized upon by pharmaceutical companies, as well as those that sell products not approved by the U.S. Food and Drug Administration, for purposes of marketing sexual medicines. Stereotypical notions of masculinity, however, also emphasize the importance of self-reliance, which may cause some to look unfavorably upon the use of sexual medicine. Consistent with this notion, a male target was viewed as more masculine when his female partner consistently reached orgasm, unless he had no history of erectile dysfunction (ED), but was taking Viagra anyway (Experiment 1; N = 522). In addition, when his partner consistently reached orgasm, ratings of his sexual esteem were also lower if he used Viagra than if he did not, but only if he had no history of ED. In Experiment 2 (N = 711), although there was no effect of a male target's use of testosterone, social perception of his masculinity and sexual esteem increased as his "natural" levels of testosterone increased. In addition, exploratory analysis revealed that if the male target had low (but not normal or high) "natural" levels of testosterone, ratings of his masculinity were higher if his female partner consistently had an orgasm, which suggests that female orgasm served to "rescue" masculinity. Because expectations about drugs drive their use, it is important to address preconceived notions about the use of sexual medicines for purposes of enhancing masculinity and sexual esteem, as the social perception of their use is much more complex.

[Men working through mobile applications in Brazil: Reflections from occupational health]. / Hombres que trabajan a través de aplicaciones móviles en Brasil: reflexiones desde la salud ocupacional.

Work through mobile applications emerged as an alternative for many Brazilian men during the economic crisis and rising unemployment. However, these workers operate informally, without a formal employment relationship, leading to labor precariousness and a lack of workers' rights. Using a theoretical-reflexive, this study analyzes the intersection between occupational health, the platformization of work, and the specific challenges faced by male delivery app workers, especially during the COVID-19 pandemic. Reflective categories are divided into two thematic sections: "Labor insertion through mobile applications in Brazil and the algorithmic work model" and "men, health, and motorcycles: occupational health and male behavior in app-based delivery work." The study examines the expansion of this type of work in the Brazilian socio-economic context, the lack of security and labor protection for these workers, as well as the risks faced, particularly during the pandemic, within a male-centric culture.

El trabajo a través de aplicaciones móviles surgió como una alternativa para muchos hombres brasileños durante la crisis económica y el aumento del desempleo. Sin embargo, estos trabajadores operan de manera informal, sin relación laboral, lo que genera precariedad laboral y falta de derechos laborales. Desde un abordaje teórico-reflexivo, este artículo analiza la intersección entre la salud ocupacional, la plataformización del trabajo y los desafíos específicos que enfrentan los hombres repartidores de aplicaciones, especialmente durante la pandemia de covid-19. Las categorías reflexivas se dividieron en dos secciones temáticas: "La inserción laboral a través de aplicaciones móviles en Brasil y el modelo de trabajo mediante algoritmos" y "hombres, salud y motocicletas: la salud ocupacional y el comportamiento masculino en el trabajo a través de aplicaciones de entrega". Se examina la expansión de este tipo de trabajo en el contexto socioeconómico brasileño, la falta de seguridad y protección laboral para estos trabajadores, así como los riesgos enfrentados, especialmente durante la pandemia, en el marco de una cultura masculina.
