This article investigates the role of space in the fiction of Jeffrey Eugenides, focusing on The Virgin Suicides (1993) and Middlesex (2002) through the lens of spatial theory. Drawing on key thinkers such as Henri Lefebvre, Michel Foucault, Edward Soja, Yi-Fu Tuan, and Doreen Massey, the study explores how Eugenides constructs spatial environments that not only frame but actively shape the identities, desires, and traumas of his characters. In The Virgin Suicides, suburban domestic spaces are shown to function as heterotopias—sites of surveillance, repression, and mythologized femininity—while Middlesex engages with transnational and urban spaces to narrate diasporic and intersex identity as dynamic, embodied, and liminal. The analysis reveals that Eugenides uses space as both a narrative device and a thematic concern to interrogate gender, memory, and power. Rather than passive backdrops, the novelistic spaces become charged arenas of conflict and transformation, reflecting and resisting dominant socio-cultural discourses. This study argues that space in Eugenides’ fiction operates as a critical register for understanding the politics of belonging and the production of subjectivity. By situating Eugenides within the broader field of literary spatiality, this article contributes to contemporary debates in literary geography, gender studies, and American fiction. Full article

Gynandromorphism of mayfly has unique biological and scientific value. However, most cases of previous studies on this phenomenon were from Europe and America, with only two cases reported from China. In this study, we examined the mayfly collections in our laboratory and obtained 21 intersex specimens belonging to three families (Baetidae, Leptophlebiidae, and Siphlonuridae) and seven species (Baetis rutilocylindratus, three unnamed Baetis species, Neoleptophlebia sp., Choroterpes facialis, and Siphlonurus lacustris), which greatly enrich the diversity of mayfly gynanders of China. Biogeographically, this phenomenon appears cosmopolitan. Regarding the potential causes of mayfly gynandromorphism, we hypothesize that inorganic factors may play a significant role. Full article

The literature details the healthcare needs of migrant people living with chronic illnesses and the consequent economic, social, and healthcare needs of their caregivers. Similarly, some studies have underscored the social and healthcare needs of 2SLGBTQIA+ (two-spirit, lesbian, gay, bisexual, transgender, queer, and intersex individuals, including diverse sexual and gender identities under the “+” symbol) adults living with chronic illnesses and their caregivers. This narrative review presents the context of migrant 2SLGBTQIA+ unpaid caregivers and how their intersecting identities influence their caregiving roles for family members with chronic illnesses. In this article, caregivers are defined as family members or chosen families who provide unpaid support that may last for three months or longer for people living with chronic illnesses. Most studies and policies overlook 2SLGBTQIA+ migrants who are also unpaid caregivers of individuals living with chronic illnesses, leaving them unsupported through discrimination at the intersection of racism, homophobia, transphobia, ageism, and ableism, forcing them to remain vulnerable to increased emotional and physical strain. There is a presence of pervasive systemic barriers, including a lack of training and education among social and healthcare providers, about the needs of migrant 2SLGBTQIA+ unpaid caregivers. Additional challenges stem from inadequate policies and insufficient targeted resources, particularly for caregivers from marginalized racial and ethnic backgrounds. The findings of this study highlight the necessity for a call to action to address these gaps and improve support systems for these highly marginalized communities. Full article

Research with population groups who have undergone circumstances of vulnerability demands a careful ethical approach to ensure that the study is conducted with the utmost respect and sensitivity, addressing potential challenges not only in regards to safeguarding participants’ rights but also in preserving the well-being of researchers. This paper is based on a qualitative research project. Employing snowball sampling techniques, I contacted 21 participants by e-mail, comprising intersex individuals who had engaged in research, as well as researchers and ethics experts with experience in qualitative intersex-related studies. I conducted semi-structured interviews to gather insights from their respective experiences. The research article focuses on a set of ethical principles that could be valuable in the development of intersex-related studies. While certain principles are directed towards participants and others towards researchers, it is important to note that these categories are not strictly delineated. As the findings suggest, these categories are closely interrelated. Both the literature review and fieldwork underscore the significance of adopting various research methods, such as community-based and trauma-informed approaches, to collaborate in enhancing knowledge production for intersex-related studies.

Congenital developmental abnormalities in piglets, such as intersex and aproctia, adversely affect survival rates, growth performance, and genetic breeding efficiency in pig populations. To elucidate their genetic basis, we performed a genome-wide association study (GWAS) on 1030 Large White pigs. We combined 50 K SNP chip data with SWIM-based genotype imputation to enhance the resolution of genetic variation detection, followed by MLM analysis. Our results identified 53 significant SNPs, with 52 associated with intersex and 1 with aproctia. Key candidate genes included MAD1L1, ID4, EFNA5, and PPP1R16B for intersex and ARNT2 for aproctia. Functional enrichment analysis highlighted pathways related to gonadal development (e.g., progesterone-mediated oocyte maturation) and embryonic morphogenesis. Collectively, the identification of these SNPs and candidate genes advances our understanding of the genetic architecture of intersex and aproctia in piglets. These findings provide actionable insights for optimizing genetic breeding strategies and improving health management in Large White pig production, with potential implications for reducing economic losses caused by congenital disorders.

DNA methylation is a form of epigenetic regulation that plays an important role in regulating gene expression of organisms. However, the DNA methylation pattern of intersex crabs has not yet been clarified. In order to reveal the DNA methylation in intersex Eriocheir sinensis, this study investigated the genome-wide DNA methylation profiles of female, male, and intersex individuals. The similar results across samples showed that the levels of cytosine methylation in the CG context were significantly higher than that in the CHG and CHH contexts. The methylation levels in the promoter region were higher than those in other functional element regions. We screened 149 differentially methylated genes (DMGs) in the promoter region between female and intersex crabs and 110 DMGs between male and intersex crabs. Three core gene networks were found in a comparison group of female and intersex crabs that involved heat shock proteins, ribosomes, and metabolism pathways; two core gene networks were found in the comparison group of male and intersex crabs that involved ribosomes and metabolism pathways. The six confirmed genes of Hsc70, Hsp90, Rpl18, Acsl1, Yip2, and Rpl7 had lower methylation levels in the promoter region of intersex crabs than that of female and male crabs. However, six genes showed higher expression in intersex crabs than in female and male crabs. Our results reveal that DNA methylation is involved in the formation and maintenance of life activities of intersex crabs through the regulation of gene expression, enriching the DNA methylation library of the whole genome of E. sinensis and providing new insights for a better understanding of the epigenetic regulation of the formation of intersex E. sinensis.

Sexual and gender minority (SGM) communities experience an increased risk for sexual victimization. Because these rates are reported in aggregate, little is known about the unique experiences of sexual violence among individuals with differences of sex development/intersex variations (DSD/I). The purpose of this study is to describe the experiences of sexual victimization in adolescents and young adults (AYAs) with DSD/I as part of a larger qualitative study exploring experiences of minority stress, stigma, and resilience. Participants were recruited through multidisciplinary care clinics and DSD/I support groups in the United States and the Netherlands. Data on sexual experiences and sexual health were analyzed thematically, with a specific focus on reports of sexual victimization. Of the 20 participants, 25% reported experiences of sexual violence. Experiences were reported across gender identities and DSD/I diagnoses. Participants described experiences as (a) resulting from DSD/I, (b) exacerbated by DSD/I, or (c) healthcare practices experienced as sexual violence. Medicalization, early loss of (bodily) autonomy, and cisgender heteronormative reproductive societal norms were reported as possible factors associated with sexual victimization experiences. The sexual victimization of individuals with DSD/I appears prevalent and associated with specific risk factors and, therefore, deserves clinical and scientific attention. Full article

Intersexuality is a reproductive phenomenon that occurs in some gonochoric species and refers to the simultaneous presence of both male and female gametes within the same individual. Although this phenomenon has been reported in various invertebrate species, many aspects remain poorly understood, especially in marine mussels. However, it has been suggested that the prevalence of parasites within populations could induce the occurrence of intersex animals. We studied intersexuality in the marine mollusk Perumytilus purpuratus, a key species of the rocky intertidal zone on the southeastern coast of the Pacific Ocean. A total of 6472 mussels from eight locations in northern and southern Chile were analyzed. We estimated the size of the specimens, the sex ratio of the population, and the prevalence of parasites. Additionally, we examined the germ cells of intersex mussels. The results showed that the male-to-female sex ratio (1:1) was maintained in the populations. Intersex mussels were found in six of the eight locations, representing 0.19% of the mussels analyzed. However, no parasites were found in the intersex animals. Additionally, the abundance of intersex individuals was not correlated with parasitism levels in the population. In intersex mussels, the gonadal tissue was compartmentalized, with male and female germ cells remaining separate. It is concluded that intersexuality in Perumytilus purpuratus is a low-frequency reproductive phenomenon, likely resulting from an alteration in the sex determination mechanism. Intersexuality offers a valuable opportunity to explore the biological aspects of sex determination in mussels. Therefore, further research in this area should be pursued. Full article

Background: Research has consistently shown increased drug use among lesbian, gay, bisexual, transgender, intersex, queer/questioning, and asexual (LGBTQIA+) individuals. This is particularly the case among LGBTQIA+ adolescents. Substance use within this vulnerable community can propagate mental health issues, leading to psychiatric disorders, self-harm, and even suicide. Therefore, the objective of this scoping review was to evaluate the determinants of drug use among LGBTQIA+ adolescents. Methods: A comprehensive search of mainly primary research was conducted, using several databases. Peer-reviewed articles published between 2018 and 2023 were included. The scoping review was conducted using the framework outlined by Joanna Briggs Institute (JBI) and reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses—Extension for Scoping Reviews (PRISMA-ScR) statement. Results: A total of 29 articles (including 400,194 participants) were included in the analysis. The articles reported that the main determinants of drug use among LGBTQIA+ adolescents include homelessness, peer–peer interactions, mental health, and protective factors. The articles reported that mental health issues, which were mainly triggered by rejection, were the main determinants of drug use among LGBTQIA+ adolescents. Conclusions: Findings from this scoping review provide relatively reliable evidence that homelessness, mental health, peer–peer interactions, and protective factors are the main determinants of illicit drug use among LGBTQ+ adolescents. Rigorous studies including large sample sizes and systematic reviews are needed to further confirm these findings and assist in developing interventions to combat the unusually high level of drug use among this group.

This article explores diverse ethical considerations related to the study of vulnerable population groups to produce meaningful project outcomes that avoid harm to the involved communities. In the specific context of the intersex community, previous analyses have encountered various challenges, including the medicalization of intersex people’s bodies, the use of pathologizing language, and misrepresentation of the population’s needs. The article explores some of the beliefs, experiences, and tools that experts in research ethics, researchers, and intersex research participants consider most important regarding research ethics in intersex-related studies. The article is based on original empirical research; semi-structured interviews were conducted with 21 participants, recruited through email and snowball sampling methods, and the data were examined using thematic analysis. It moves from issues related to the research design (positionality, researcher preparation, framing intersex within the LGBT acronym) to experiences related to the research development (ethical approval, informed consent process, language use, relationship of trust). The article describes some of the major concerns and raises discussions that could be relevant for the development of future research under human rights-based perspectives. The findings are aimed to be useful beyond the field of intersex-related studies, as they can be relevant to research about other communities that have endured violations of their human rights during research.

After a decade of work, Brújula Intersexual has become a reference in Mexico and Latin America. However, the presence of the Latin American intersex movement in the specialised literature in English is restricted. We consider that conducting a self-reflexive review of Brújula Intersexual could contribute to understanding (1) the work strategies implemented by Brújula Intersexual; (2) the formation of the Spanish-speaking intersex community and movement in Mexico; and (3) the heterogeneous dynamics of the global intersex movement. We designed a qualitative–quantitative study involving discussion meetings with the Brújula Intersexual team, revision of the Brújula Intersexual archive, a scoping review, and a timeline. The results and discussion are focused on two axes: (1) Brújula Intersexual: structure and working strategies, in which two concepts are developed, namely, the intimate sphere and the atmosphere of trust; (2) The articulation of Brújula Intersexual within the intersex movement and its resonances in public policy. Researching Brújula Intersexual contributes to the collective memory and reveals important events that link the Spanish-speaking and global anglophone intersex movements. In particular, Brújula Intersexual was configured as a critical counter-device that manages intense flows of affection, allowing for the production of new subjectivation modes for people with intersex bodies.

Over the last decades, intersex studies has achieved increasing development as a field of critical knowledge, in tight collaboration with discourses developed by intersex activism and human rights bodies. This paper proposes a self-reflexive review of epistemological perspectives in intersex studies within broader discursive fields, through a thematic analysis and comparative framing analysis. This analysis is based on a narrative literature review of academic contributions, activist declarations, and documents issued by human rights bodies conducted over the last decade as a work-in-progress project. Furthermore, it includes results of a scoping review of recent knowledge production in intersex studies carried out in Scopus within the subject area ‘social sciences’. This paper focuses on the analysis of the following epistemological perspectives: human rights frameworks, legal perspectives and citizenship theories, reflections on biopolitics, medicalization and iatrogenesis, sociology of diagnosis framework, depathologization perspective, respectful health care models, and reflections on epistemological, methodological, and ethical aspects. The literature review raises questions about the existence of specific intersex epistemologies in intersex studies, their interrelation with discourses contributed by intersex activism and human rights bodies, and the opportunities for a contribution of theory making in intersex studies to the human rights protection of intersex people.

The oriental fruit fly, Bactrocera dorsalis (Hendel), poses a significant threat to the global fruit industry, causing damage to diverse fruits like citrus, mango, and guava. Chemical pesticides have limited effectiveness, and pesticide residues and pesticide resistance are pressing issues. Therefore, it is essential to develop environmentally friendly pest control methods to address this problem. Behavior-modifying chemicals, including male attractants and intersex protein baits, play a critical role in the control of B. dorsalis. The mature host fruit serves as both an oviposition site and food source under natural conditions, making it a potential attraction source for oriental fruit flies. Orange, Citrus sinensis, is a main host of B. dorsalis, and commercial orange juice is a common attractant for the egg laying of B. dorsalis. Although it can both attract and elicit oviposition behaviors in B. dorsalis adults, its active components are still unclear. This study utilized analytical chemistry, behavioral tests, and electrophysiology to identify the active components of commercial orange juice that attract B. dorsalis, with the aim of providing a reference for the development of behavior-modifying chemical-based techniques to control B. dorsalis. Five compounds with a high abundance were identified via a GC-MS, including D-Limonene, butanoic acid ethyl ester, β-myrcene, linalool, and α-terpineol. Behavioral and electrophysiological experiments uncovered that D-Limonene was the active substance that was the main attractant in the mixture of these five substances, evoking a strong electrophysiological response in adult B. dorsalis. D-Limonene strongly attracts adult B. dorsalis only when they are sexually mature, and the attraction is not rhythmic. Olfaction plays a leading role in the attraction of D-Limonene to adult B. dorsalis, and Orco^−/− mediates the perception of D-Limonene by B. dorsalis. Overall, D-Limonene is one of the key attractant compounds for B. dorsalis in the volatile compounds of commercial orange juice, offering possible support for the development of behavior-modifying chemical-based technology to control B. dorsalis in the future.

Previous research has indicated that intersex people face specific challenges in their sexual development, including uncertainties or confusion about their gender, a negative genital self-image, and hesitance to engage in romantic and sexual relationships. However, in-depth knowledge regarding a central period in this development, adolescence, is missing. In our qualitative study, we explore which factors influence the relational and sexual development of intersex youth and what elements contribute to positive development. We interviewed eighteen intersex persons aged 18–38. We identified three main themes: (1) intersex experiences, (2) the described sexual and relational life course, and (3) factors influencing a positive development. Our findings show that intersex youth face many obstacles in their relational and sexual development, many of which are related to healthcare. However, their life stories also illuminate how healthcare professionals, as well as parents, friends, partners, teachers, and others, can make a substantial difference in intersex lives by breaking normative, binary thinking on sex and gender.
