Examining the Fraternal Birth Order Effect and Sexual Orientation: Insights from an East European Population.

The development of human sexual orientation remains a complex and multifaceted subject. It is often studied but its origins continue to elude us. In this preregistered study, our primary objective was to demonstrate the fraternal birth order effect (FBOE), which assumes a higher prevalence of older brothers in gay men than in their straight counterparts and which has also been recently recorded in lesbian women. Our second aim was to explore any potential impact of the FBOE on anal-erotic role orientation (AERO), both in gay and straight men. Our study sample included 693 gay men, 843 straight men, 265 lesbian women, and 331 straight women from Czechia and Slovakia. Employing a conventionally parameterized logistic regression model, we substantiated the FBOE among both gay men (OR = 1.35 for maternal older brothers) and lesbian women (OR = 1.71). These outcomes were confirmed by a more nuanced parameterization recently proposed by Blanchard (2022). Nonmaternal older brothers did not exhibit a significant influence on their younger brothers' sexual orientation. Contrary to some earlier reports, however, our data did not establish the FBOE as exclusive to gay men with the receptive AERO. Furthermore, our observations indicated a lower offspring count for mothers of gay men compared to mothers of straight men. Emphasizing the positive FBOE outcomes, we acknowledge the need for caution regarding the various options that can be used to estimate the familial influences on sexual orientation.

Intense Body Contact Increases Homosexual Pair Bond Stability in Female Japanese Macaques (Macaca fuscata).

The Japanese macaque (Macaca fuscata) has become a key species for studying homosexual behavior over recent decades. With the non-conceptive nature, their same-sex consortships illustrate that individual partner preferences can exist beyond direct reproductive benefits or apparent sociosexual strategies. An open question is whether the behavior shared between partners in consortship directly affects their choice to remain with a partner. With this study, we examined behavioral aspects underlying consortship temporal patterns in these promiscuous and bisexual primates. While these patterns could be relevant in both homo- and heterosexual consortships, our study primarily focused on female-female pairs. We hypothesized that the stability of consortships (duration and occurrence) is influenced by a pair's sexual behavior, mutual sexual stimulation, and close affiliative inter-mount behaviors involving high-intensity body contact. A semi-free population of Japanese macaques was observed over one mating season. In total, 40 h of focal data on female-female consortship behaviors were analyzed. Forty-six percent of all sexually mature females engaged in homosexual interactions. Our behavioral analyses of female-female pairs found that close body contact, rather than grooming or sexual interactions, was correlated with the stability of homosexual consortships. The greater the amount of huddling and embracing a pair engaged in, the more likely they were to stay together and reunite again. However, the frequency of mounting, rubbing or thrusting had no discernable effect on consortship stability. The results of this study thus add important knowledge to partner qualities in promiscuous primates as well as to inter-group differences of homosexual behavior in Japanese macaques.

Saúde sexual e acesso aos serviços para mulheres lésbicas em Manaus, Amazonas, Brasil / Sexual health and access to services for lesbian women in Manaus, Brazil

Resumo O estudo tem por objetivo compreender os significados relacionados à saúde sexual e os contornos que definem a experiência de acesso aos serviços de saúde para mulheres lésbicas de Manaus, Amazonas. Trata-se de uma pesquisa de abordagem qualitativa. Contou com a participação de dez mulheres que se autoidentificaram como lésbicas. Foram realizadas entrevistas semiestruturadas e suas análises ocorreram por meio de três eixos temáticos. O primeiro abordou as representações sobre prevenção e práticas sexuais, destacando a noção de fidelidade no relacionamento como "fator de proteção". Foram relatadas dificuldades no uso de preservativos em relações entre duas mulheres. O segundo discutiu a heteronormatividade e seus efeitos no cuidado de si, relatando as dificuldades de as participantes serem compreendidas e acolhidas pelos serviços de saúde. O terceiro abordou a busca do próprio conhecimento como tática de cuidado, destacando a importância da informação e da autonomia para a promoção da saúde e a prevenção de infecções sexualmente transmissíveis. Conclui-se que existe a necessidade de políticas públicas voltadas para a promoção da saúde sexual de mulheres lésbicas e o reconhecimento de suas especificidades pelos serviços de saúde.

Abstract This study aims to understand the meanings related to sexual health and the delineations that define the experience of accessing health services for lesbian women in Manaus, Brazil. This study followed a qualitative approach, counting on the participation of ten women who self-reported themselves as lesbians. Semi-structured interviews were carried out and their analyses occurred through three thematic axes. The first addressed the representations concerning prevention and sexual practices, highlighting the notion of fidelity in the relationship as a "protective factor". Difficulties in the use of condoms in relationships between two women were reported. The second discussed heteronormativity and its effects on self-care, reporting the participants' difficulties in being understood and welcomed by health services. The third addressed the search for one's own knowledge as a care tactic, highlighting the importance of information and autonomy for health promotion and prevention of Sexually Transmitted Infections (STIs). It can therefore be concluded that there is a need for public policies aimed at promoting the sexual health of lesbian women and the recognition of their specificities by health services.

Factors associated with bacterial vaginosis in women with homosexual, bisexual and heterosexual practices.

BACKGROUND: The factors associated with bacterial vaginosis in women with homosexual, bisexual and heterosexual practices are still poorly explored. Thus, the aim of this study was to analyze the factors associated with bacterial vaginosis in women with different sexual practices. METHODS: Cross-sectional study that included 453 women, 149 Women with Homosexual practice (WSW); 80 bisexual Women (WSWM) and 224 Women with heterosexual practice (WSM). The diagnosis of bacterial vaginosis was performed by microscopic examination of the vaginal smears stained by Gram method and classified according to the Nugent et al. (1991) score. Data analysis was performed by Cox multiple regression. RESULTS: Bacterial vaginosis was associated to years of education among WSW (0.91 [95% CI 0.82‒0.99]; p = 0.048) and non-white skin color (2.34 [95% CI 1.05‒5.19]; p = 0.037) between WSWM. Changing partners in the last 3-months (2.09 [95% CI 1.14‒3.82]; p = 0.017), inconsistent use of condoms (2.61 [95% CI 1.10‒6.20]; p = 0.030) and positive diagnosis of Chlamydia trachomatis (2.40 [95% CI 1.01‒5.73]; p = 0.048) were associated with bacterial vaginoses only in WSH. CONCLUSIONS: The factors associated to bacterial vaginosis differ between different sexual practices, suggesting that the type of sexual partner may influence the risk of developing this classic dysbiosis.

Conhecimento de mulheres que fazem sexo com mulheres sobre Infecções Sexualmente Transmissíveis e Aids / Knowledge of women who have sex with women about Sexually Transmitted Infections and AIDS

Resumo O objetivo deste artigo é estudar o conhecimento de mulheres que fazem sexo com mulheres sobre Infecções Sexualmente Transmissíveis e Aids. Estudo transversal com 260 mulheres, sendo 81 mulheres que fazem sexo com mulheres ou com mulheres e homens (MSM) e 179 mulheres que fazem sexo exclusivamente com homens (MSH). Dados obtidos entre 2019 e 2020, por meio de aplicação de formulário e de instrumentos validados. Para estudar a associação entre parceria sexual e nível de conhecimento sobre Infecções Sexualmente Transmissíveis e Aids foram ajustados modelos de regressão múltipla de Cox, sendo significativas as associações com p<0,05. A mediana do percentual de acerto das questões foi inferior entre às MSM quando comparadas às das MSH [68% (18-96) vs 75% (14-96); p=0,023]. Fazer sexo com mulher [RP=2,36 (1,07-5,21); p=0,033] e escolaridade menor que 11 anos de estudo [RP=2,64 (1,12-6,21); p=0,026] associaram-se independentemente ao baixo conhecimento. As MSM apresentaram menor nível de conhecimento sobre Infecções Sexualmente Transmissíveis e Aids do que as MSH, assim como a menor escolaridade associou-se independentemente a esse desfecho.

Abstract This article aims to study the knowledge of women who have sex with women about Sexually Transmitted Infections and AIDS. Cross-sectional study of 260 women, 81 women who either have sex with women or with men and women (WSW) and 179 women who have sex exclusively with men (WSM). Data were collected in 2019/2020 by means of a form and validated instruments. To study the association between sexual partnership and level of knowledge about Sexually Transmitted Infections and AIDS, multiple Cox regression models were adjusted, producing significant associations of p<0,05. The median percentage of correct answers was lower among WSW when compared to WSM [68% (18-96) vs 75% (14-96); p=0.023]. Having sex with woman [PR=2.36 (1.07-5.21); p=0.033] and less than 11 years of schooling [PR=2.64 (1.12-6.21); p=0.026] were independently associated with low knowledge. WSW had a lower level of knowledge about Sexually Transmitted Infections and AIDS than WSM, and lower education was independently associated with this finding.

Female Homosexuality and (Non)Performativity in the 21st-C. Syrian Novel: Queerness as/at Home in Samar Yazbek's Ra'ihat al-Qirfa (2008)/Cinnamon (2012).

Given the regression in empowering representations of queer women in the literary and, more generally, the cultural life of the modern Arab world, this article spotlights the hitherto under-researched literary portrayals of female homosexuality as a site of redemptive and/or reparative, queer(ed) home in 21st-century Syria. Through a close reading of Samar Yazbek's Ra'ihat al-Qirfa (2008), and, for added nuance, its English translation Cinnamon (2012), the study explores the novel's curation of home in and through the protagonist Aliyah's same-sex relationship with her employer Hanan al-Hashimi. Using Roberta Rubenstein's and Sara Ahmed's notions of fixing past homes, and of queer(ing) home, respectively, the article shows how the sense of home cushioned by the same-sex affair transcends social class and domination/submission binaries. I thus argue that even as the same-sex relationship in Yazbek's novel may not be performative from a contemporary lesbian feminist perspective, it kneads hope, not desolation, into the plot and the real-life setting it extrapolates, since it responds to the local context the characters inhabit.

Experiences of Violence Against Lesbian and Bisexual Women in Brazil.

BACKGROUND: Lesbophobia and biphobia are manifestations of homophobic violence directed at lesbian and bisexual women that results in daily violation of rights and social exclusion. AIM: To describe experiences of the violence against lesbian and bisexual women in Brazil. METHODS: Sequential mixed methods study was carried out in 2 stages. In the first one, quantitative, an electronic questionnaire was applied to women from all regions, with questions about sociodemographic characteristics, self-identification and lesbophobic and biphobic events. In the second one, qualitative, lesbian, and bisexual women were interviewed face to face about the violence suffered. OUTCOMES: The chi-square test was applied to compare violence against lesbian and bisexual women (type of violence, place of aggression, gender and age range of the aggressor, bond with the aggressor, repetition of violence, and denunciation of violence) and the content analysis for qualitative data (main categories of analysis were events of violence, denunciation, and consequences of violence). RESULTS: The report of violence was present in 65% of the answers. There was a predominance of psychological violence (39.8%), in the public environment (63%), practiced by men (73.2%), by strangers (66.2%) and repeatedly (82%). Lesbian women, compared to bisexuals, were more prone to violence in the public environment (59.5% vs 39.5%) and with repetition (84.3% vs 60.6%). The narratives explained intimidating experiences in the family environment (insults, threat of suicide or homicide and false imprisonment) and public (harassment, beatings, and rape). Discriminatory attitudes, insults, and refusal of service in restaurants and bars were recurrent. CLINICAL IMPLICATIONS: The data provide information that can serve to improve policy initiatives to reduce these episodes. STRENGTHS AND LIMITATIONS: This is the first study of mixed methods, with national coverage, on lesbophobia and biphobia events in Brazil. Future studies should include women underrepresented in this research as trans women, non-white, less educated, and from the most distant regions of the country. CONCLUSION: Lesbophobic or biphobic event has harmful repercussions for multiple aspects of these women's lives, including mental health. Rufino AC, Filho CEWBdeC, Madeiro A.

Acesso de mulheres lésbicas aos serviços de saúde à luz da literatura / Access to health services for lesbian women: a literature review

Resumo O trabalho tem como objetivo explorar como se afiguram as especificidades do acesso de lésbicas aos serviços de saúde à luz da literatura. Como metodologia, realizou-se uma pesquisa bibliográfica e, em seguida, com base nos achados do acervo analisado, produziu-se uma síntese interpretativa ancorada em aspectos teóricos de Pierre Bourdieu. Em relação aos resultados, destacam-se duas temáticas com seus respectivos núcleos de sentidos: (a) barreiras e dificuldades do acesso de lésbicas à atenção à saúde (questões relacionadas à revelação de ser lésbica e dificuldades de os serviços e profissionais de saúde lidarem com essas mulheres) e (b) experiências das lésbicas nos serviços de saúde (atendimento desigual, invisibilidade e constrangimento). No que se refere a conclusões, dentre outros aspectos, observa-se que, apesar dos avanços em relação a políticas e protocolos de atendimento a população em questão, as diversidades sexual e de gênero devem ser amplamente debatidas nos espaços sociais, de formação e de atenção à saúde.

Abstract This study explores access to health services for lesbians in the light of current literature. A literature search was conducted using various databases and an interpretive synthesis of the findings of the selected articles was produced anchored in the concepts of habitus and symbolic violence developed by Pierre Bourdieu. Two main themes and their respective units of meaning were identified: (a) barriers and difficulties experienced by lesbians in accessing healthcare (issues related to coming out as a lesbian and difficulties experienced by health services and professionals in dealing with lesbian women); and (b) lesbian women's experiences in health services (unequal care, invisibility, and feeling uncomfortable). We conclude that, despite advances in policy and care protocols, sexual and gender diversity needs to be widely discussed in social, educational, and health settings.

A manless adultery: the story of Bassa as related in a Marcus Valerius Martialis' epigram.

During the Golden Age of the Roman Empire, Rome was transformed into a magnificent city where architecture, the arts, and commerce flourished. An inconceivable amount of wealth was accumulated by a handful of noble families, while the masses starved. In such a context, moral values inevitably decline, while sexual mores are liberalized and ever more veer towards salacity. This reality was elegantly illustrated in short, often sarcastic poems known as epigrams. Herein, we present a case of a woman with enigmatic appearance of the external genitalia, exhibiting unrestrained homosexual activity, as described in an epigram by Marcus Valerius Martialis (a contemporary poet who lived in the 1st century AD). Based on the information provided in the ancient text, we formulate a differential diagnosis and deduce that this woman was, in fact, a case of congenital adrenal hyperplasia (CAH). To our knowledge, this is the earliest literary description worldwide of a case of CAH as a cause of homosexuality and unquenchable lust.

Homosexualidad masculina y lesbianismo en la psicología china: revisión sistemática entre 2012 y 2016 / Male homosexuality and lesbianism in Chinese psychology: systematic review between 2012 and 2016

Resumen Para identificar el estudio y enfoque que la psicología de China realiza sobre la homosexualidad y el lesbianismo se realizó una revisión sistemática de la bibliografía publicada entre 2012-2016. Se realizó la búsqueda en seis bases de datos: BVS, Dialnet, PsycINFO (PsycNET), Scopus, Web of Science y CNKI (中国知网). Como resultado, se encontraron 240 artículos: 202 de la China continental, 30 de Hong Kong y 12 de Taiwan. Se analizaron los idiomas utilizados, cantidad de publicación en cada año, las áreas de psicología en que se publican y los temas de los artículos publicados se han organizado en doce categorías. A partir de los resultados, presentamos una discusión sobre la patologización construida de la población homosexual, la invisibilidad de la población homosexual femenina, la hegemonía de la lengua inglesa y el efecto de la censura de la publicación científica.

Abstract To identify the study and the approach Chinese psychology takes on homosexuality and lesbianism, a systematic review of the bibliography published between 2012 and 2016 was conducted. The search was made in six databases: BVS, Dialnet, PsycINFO (PsycNET), Scopus, Web of Science and CNKI (中国知网). As result, 240 articles were found: 202 from mainland China, 30 from Hong Kong, and 12 from Taiwan. We analyzed the languages used, amount of publication in each year, the areas of psychology in which they were published and the topics of the published articles have been organized into 12 categories. Based on the results, we present a discussion on the constructed pathologization of the homosexual population, the invisibility of the female homosexual population, the hegemony of the English language and the effect of censorship of scientific publication.

Vulnerabilidade de mulheres que fazem sexo com mulheres às infecções sexualmente transmissíveis / Vulnerability to sexually transmitted infections of women who have sex with women

Resumo O objetivo do presente estudo foi identificar as dimensões da vulnerabilidade de mulheres que fazem sexo com mulheres associadas às infecções sexualmente transmissíveis. Estudo transversal com 150 mulheres, entre 2015-2017. Aplicou-se questionário estruturado, realizou-se exame ginecológico para diagnóstico de Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, papiloma vírus humano e coleta de sangue periférico para detecção de HIV, hepatite B e sífilis. A variável desfecho foi a ocorrência de infecção sexual e as variáveis independentes compõem o referencial da vulnerabilidade, nas dimensões individual, social e programática. Análise de dados foi realizada por modelo de regressão logística. Os resultados mostraram alta prevalência das infecções (47,3%) e apenas variáveis relacionadas à vulnerabilidade individual se associaram de forma independente ao desfecho: chance de infecção foi quatro vezes maior entre mulheres com antecedente de infecção; nunca ter realizado exame sorológico aumentou a chance em quase três vezes e ter tido relação sexual com homem nos últimos 12 meses aumentou em quase nove vezes a chance do desfecho. Concluiu-se que essas mulheres são vulneráveis às infecções sexualmente transmissíveis em decorrência da vulnerabilidade individual.

Abstract The scope of this study was to assess the degree of vulnerability to sexually transmitted infections of women who have sex with women. It involved a cross-sectional study of 150 women between 2015 and 2017. A structured questionnaire was applied, and a gynecological examination was performed to diagnose Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis and papillomavirus. Blood tests were conducted to detect HIV, hepatitis B and syphilis. The outcome variable was sexual infection and the independent variables comprised the vulnerability level in the individual, social and programmatic dimensions. Data analyses were performed through logistic regression. The results showed a high prevalence of infections (47.3%) and only variables of individual vulnerability were associated with the outcome. The incidence of infection was four times higher among women who had had prior infections. The fact of never having had a blood test tripled the chance of having sexually transmitted infections. The fact of also having sexual intercourse with men in the previous 12-month-period increased the risk of the outcome by a factor of approximately nine. The conclusion drawn is that these women are vulnerable to sexually transmitted infections due to their individual vulnerability.

Constructed Realities: Claude Cahun's Created World in Aveux Non Avenus.

In her 1930 publication, Aveux non Avenus, Claude Cahun used the relationship between her inwardly focused poetic writing and symbolic photomontages to construct a unique reality for self-expression. This article focuses on three chapters and respective photographic images from the publication to relate Cahun's, and by association her partner Marcel Moore's, discussion on sexuality and gender expression. The utopian dreamscape created investigates issues of narcissism and otherness, female homosexuality, dandyism and going beyond gender, individual and social critique, mocking the antiquated views of art and writing, accepting and breaking taboos, while allowing for other departures from the accepted norm. Through analysis of the publication and supporting evidence from early influences, it can be seen that Cahun created a world in Aveux non Avenus where she could exist in a space between the established feminine-masculine binary of 20th-century Europe.

A review of the role of Malawi's law reform agency in criminalization and decriminalization of female same-sex sexual conduct.

The Law Commission is an institution created by Malawi's 1995 Constitution with the mandate to review and recommend laws to be in conformity with the Constitution and international law. In 2000, the Commission recommended, for the first time in the history of Malawi, the criminalization of female same-sex sexual conduct. This was enacted into law in 2011. This article examines the role of the Commission in influencing the development of sex- and gender-related laws to address gender inequality and discrimination. It describes the historical context of legal developments since colonial times, leading to the adoption of a democratic constitution and commitment to incorporating human rights norms and standards in national laws. It argues that, in contradiction to its mandate, the Commission played an influential role in the development of a law that further marginalizes women and entrenches sex discrimination. It concludes that the Commission should therefore take responsibility for its actions and review the offending law sua sponte.

Prevalence of sexually transmitted infections and bacterial vaginosis among lesbian women: systematic review and recommendations to improve care / Prevalência de infecções sexualmente transmissíveis e vaginose bacteriana em mulheres lésbicas: revisão sistemática e recomendações para melhoria do cuidado / Prevalencia de infecciones sexualmente transmisibles y vaginosis bacteriana entre mujeres lesbianas: revisión sistemática y recomendaciones para mejorar el cuidado

Our aim was to systematically review data about the risk of sexually transmitted infections (STI) and bacterial vaginosis among lesbian women and to suggest strategies to improve prevention, diagnosis and treatment. A search strategy for lesbian, STI and bacterial vaginosis was applied to PubMed, LILACS and BDENF databases. Of 387 unique references retrieved, 22 fulfilled the inclusion criteria (cross-sectional studies reporting prevalence for 8 STIs/bacterial vaginosis and history of a STI). The most frequent infection reported was bacterial vaginosis, and none study reported data on hepatitis B. A wide range of prevalence was observed for most infections. In terms of risk factors, the number of sexual partners, the past or current smoking, a history of forced sex and sexual stigma seem to increase the risk of STI and bacterial vaginosis. The findings of this review are discussed considering guidelines directly addressing the LGBT community's health and relevant studies investigating both safe sexual practices and the intricate relationship between LGBT people and their care providers. A set of recommendations to improve preventive care for lesbian women is proposed. Affirming that little is known about the extent of STIs and bacterial vaginosis transmission in female-to-female sexual activities or about the risk factors for STI and bacterial vaginosis among lesbian women is reasonable. In fact, the overall quality of the studies was low or very low with significant uncertainty around their findings. However, we consider that the available knowledge indicates some paths to be followed by care providers and policy decision-makers to improve their actions towards better sexual health of lesbian women.

Nosso objetivo foi revisar sistematicamente dados sobre o risco de infecções sexualmente transmissíveis (ISTs) e vaginose bacteriana em mulheres lésbicas e sugerir estratégias para melhorar prevenção, diagnóstico e tratamento. Uma estratégia de busca para lésbica, ISTs e vaginose bacteriana foi aplicada às bases PubMed, LILACS e BDENF. De 387 referências únicas identificadas, 22 preenchiam os critérios de inclusão (estudos seccionais relatando a prevalência de 8 ISTs/vaginose bacteriana e histórico de ISTs). A infecção mais frequentemente relatada foi vaginose bacteriana e nenhum estudo relatou dados sobre hepatite B. Uma ampla gama de prevalências foi observada para a maioria das infecções. Em termos de fatores de risco, o número de parceiras sexuais, ser ou ter sido fumante, histórico de sexo forçado e estigma sexual parecem aumentar o risco de ISTs e vaginose bacteriana. Os resultados desta revisão são discutidos à luz de diretrizes que abordam diretamente a saúde da comunidade LGBT e também de estudos relevantes que investigaram tanto práticas de sexo seguro quanto a complexa relação entre pessoas LGBT e profissionais de saúde. Um conjunto de recomendações para melhorar o cuidado preventivo para mulheres lésbicas é proposto. É razoável afirmar que pouco se sabe sobre a dimensão da transmissão de ISTs e vaginose bacteriana em atividades sexuais entre mulheres ou sobre os fatores de risco para ISTs e vaginose bacteriana em mulheres lésbicas. De fato, a qualidade dos estudos foi, de forma geral, baixa ou muito baixa, com incerteza significativa quanto a seus resultados. Contudo, consideramos que o conhecimento disponível indica alguns caminhos a serem seguidos por profissionais de saúde e na elaboração de políticas públicas para melhorar ações em direção a uma melhor saúde sexual de mulheres lésbicas.

Nuestro objetivo fue realizar una revisión sistemática de los datos sobre infecciones de trasmisión sexual (ITS) y riesgo de vaginosis bacteriana entre mujeres lesbianas y sugerir estrategias para mejorar su prevención, diagnóstico y tratamiento. La estrategia de búsqueda de lesbiana, ITS y vaginosis bacteriana se realizó en las bases de datos de PubMed, LILACS y BDENF. De 387 referencias únicas recogidas, 22 reunían criterios de inclusión (estudios transversales informaron sobre la prevalencia de 8 ITS/vaginosis bacteriana e historial de una ITS). La infección más frecuente fue vaginosis bacteriana y ningún estudio proporcionó datos sobre hepatitis B. se observó un amplio rango de prevalencia para la mayoría de las infecciones. En términos de factores de riesgo, el número de parejas sexuales, ser fumador o exfumador, un pasado de abusos sexuales, así como el estigma sexual parece que incrementaron el riesgo de ITS y vaginosis bacteriana. Los hallazgos del presente estudio se discuten a la luz de las directrices de salud directamente dirigidas a la comunidad LGBT, y también a estudios relevantes que investigaban tanto las prácticas sexuales seguras, como la relación intricada entre individuos del colectivo LGBT y sus proveedores de salud. Se propone un conjunto de recomendaciones para mejorar el cuidado preventivo de mujeres lesbianas. Es razonable afirmar que se conoce poco sobre el grado de transmisión de las ITS y vaginosis bacteriana en las relaciones sexuales entre mujeres o sobre los factores de riesgo para las ITS y vaginosis bacteriana entre mujeres lesbianas. De hecho, la calidad general de los estudios fue baja o muy baja con una incertidumbre significativa sobre sus resultados. No obstante, consideramos que el conocimiento disponible indica algunos caminos que pueden recorrer proveedores de salud y tomadores decisiones para mejorar sus acciones orientadas a una mejor salud sexual de las mujeres lesbianas.

Vivencias de usuarias lesbianas sobre el proceso de atención perinatal en la región metropolitana, Chile en 2016 / Experiences of lesbian users about the process of perinatal care in the metropolitan region of Chile in 2016 / Vivências de usuárias lésbicas sobre o processo de atenção perinatal na região metropolitana do Chile em 2016

El objectivo de la investigación fue explorar las vivencias de la atención perinatal de usuarias lesbianas en la Región Metropolitana, Chile en 2016. Se trata de un estudio transversal exploratorio con enfoque fenomenológico, usando la estrategia muestral bola de nieve. Fueron realizadas entrevistas en profundidad con análisis de contenido. Se han experimentado vivencias favorables de las usuarias lesbianas sobre su proceso de gestación, parto y puerperio y un trato inclusivo y antidiscriminatorio de los proveedores de salud. Hay una aceptación generalizada de los profesionales de salud hacia las familias homoparentales y a la visibilización de la homosexualidad. El empoderamiento y la autoestima de las usuarias entrevistadas es un elemento que favorece la relación médico-paciente. Sin embargo, las alternativas para acceder a la maternidad no se encuentran asequibles para toda la población debido al alto costo que poseen.(AU)

The study aimed to explore the experiences of perinatal care of lesbian users in the metropolitan area of Chile in 2016. It was a cross-sectional and phenomenological study with snowball sampling. In-depth interviews were carried out and the reports were interpreted using the content analysis technique. The interviews revealed positive experiences by lesbian users during their pregnancy, childbirth and postpartum periods, and an inclusive treatment, with no prejudice by healthcare providers. There is a broad acceptance by healthcare professionals of homosexual families and the visibility of homosexuality. The empowerment and self-esteem exhibited by the interviewed users favor the doctor-patient relationship. However, the alternatives to achieve motherhood are not available for the entire population because of their high cost.(AU)

O objetivo do trabalho foi percorrer as vivências da atenção perinatal, de usuárias lésbicas na região metropolitana do Chile em 2016. Trata-se de estudo transversal de exploração com abordagem fenomenológica, utilizando a amostragem em bola de neve. Foram realizadas entrevistas em profundidade, com análise de conteúdo. Foram observadas vivências favoráveis das usuárias lésbicas acerca de seus processos de gestação, parto e puerpério, e um tratamento inclusivo e sem discriminação dos prestadores de saúde. Existe uma geral aceitação dos profissionais da saúde em relação às famílias homossexuais e à visibilidade da homossexualidade. O empoderamento e a autoestima das usuárias entrevistadas é um elemento que favorece o relacionamento médico-paciente. Porém, as alternativas para alcançar a maternidade não são acessíveis para toda a população, devido ao alto custo que elas têm.(AU)

Possible Balancing Selection in Human Female Homosexuality.

A growing number of researchers suggest that female homosexuality is at least in part influenced by genetic factors. Unlike for male homosexuality, few familial studies have attempted to explore maintenance of this apparently fitness-detrimental trait in the population. Using multiple recruitment methods, we explored fecundity and sexual orientation within the pedigrees of 1,458 adult female respondents. We compared 487 homosexual and 163 bisexual with 808 heterosexual females and 30,203 of their relatives. Our data suggest that the direct fitness of homosexual females is four times lower than the direct fitness of heterosexual females of corresponding ages. The prevalence of nonheterosexuality within the homosexual female respondents' families (2.83%) appear to be more than four times higher than the basal prevalence in the Italian population (0.63%). Pedigree size and relative fecundity in both the paternal and maternal sides of the homosexual women's families were significantly higher than in the heterosexuals' families. If confirmed, the relative average fecundity increase within the family seems to offset the loss in fitness due to the low direct fitness of homosexual females. Therefore, the balanced fecundity in the homosexual females' families may allow the trait to be maintained at a low-frequency equilibrium in the population.

The Sexual Health of Women in Lebanon: Are There Differences by Sexual Orientation?

PURPOSE: From studies conducted in Western countries (United States, United Kingdom, and Australia), we know that the sexual health of sexual minority women (SMW) differs in key ways from that of heterosexual women (HSW). To date, the sexual health of SMW living in the Middle East and North Africa region has not been studied. The purpose of this study was to compare the sexual health of SMW and HSW living in Lebanon. METHODS: SMW and HSW living in Lebanon (N = 95) completed an anonymous, self-administered survey. SMW's risk perceptions and health promoting and sexual behaviors were compared to those of HSW. We examined differences by sexual orientation by using t tests and Fisher's exact tests. RESULTS: The 45 SMW and 50 HSW had similar demographic characteristics. Significantly more SMW had heard of human papillomavirus, but only 22% of women from both groups knew of its association with abnormal Papanicolaou tests. Cervical cancer screening rates were similar in SMW and HSW, although remarkably low (42%) compared with rates in Western countries. Significantly more SMW (18%) reported difficulty with access to care than HSW (0%). Forty-four percent of SMW reported discomfort in disclosing their sexual orientation to their healthcare provider and 61% reported that healthcare providers lacked sensitivity toward lesbian, gay, bisexual, and transgender needs. Unwanted sexual contact occurred more frequently in SMW (53%) than HSW (23%). CONCLUSION: The sexual health of women is affected by sociocultural factors. SMW living in Lebanon have unique health needs that should be addressed within their sociocultural context.

Social network: evaluation of the support or containment contexts of lesbian mothers / Red social: la evaluación del contexto de apoyo o contención de madres lesbianas / Rede social: avaliação do contexto de apoio ou contenção de mães lésbicas

ABSTRACT Objective: To evaluate the social network of lesbian mothers, from the social contexts of support or restraint. Method: Descriptive, exploratory study, of qualitative approach, based on the theoretical reference of Social Network, with eight lesbian mothers selected through Snowball technique, using semi-structured interview. Data analysis was performed with IRAMUTEQ software, through Similarity Analysis. Results: The social network is configured as: 1) Emotional distance and non-acceptance of motherhood by the family members - primary network elements; 2) Interference in the socio-cultural medium for the effectiveness of the mother-child bond - secondary network elements. Final considerations: Social network is grounded on trivialized and negative conceptions that highlight prejudice and disrespect. The discussion of this theme contributes to a greater visibility of those new family arrangements as well as to reduce stigmas e prejudices that pervade the social network components of these women.

RESUMEN Objetivo: Evaluar la red social de madres lesbianas desde el contexto social de apoyo o contención. Método: Estudio descriptivo, exploratorio, de abordaje cualitativo, anclado en el referencial teórico Red Social, con ocho madres lesbianas, seleccionadas por medio de la técnica Snowball, de acuerdo con la encuesta semiestructurada. Se realizó el análisis de los datos por el programa (software) IRAMUTEQ por el Análisis de Similitud. Resultados: La red social se configura en: 1) La distancia afectiva y no la aceptación de la maternidad por los familiares - elementos de la red primaria; 2) Las interferencias en el medio sociocultural para la efectuación del vínculo madre e hijo - los elementos de la red secundaria. Consideraciones finales: La red social está basada en las concepciones banalizadoras y negativistas que subrayan el prejuicio y la falta de respeto. Tratar de este tema es aportar para la mayor visibilidad a esos nuevos arreglos familiares, así como para disminuir los estigmas y prejuicios que permean los elementos componentes de la red social de esas mujeres.

Tratar deste tema é contribuir para maior visibilidade a esses novos arranjos familiares, bem como para diminuir os estigmas e preconceitos que permeiam os elementos componentes da rede social dessas mulheres.

Prevalence of bacterial vaginosis and factors associated among women who have sex with women / Prevalência de vaginose bacteriana e fatores associados em mulheres que fazem sexo com mulheres / Prevalencia de vaginosis bacteriana y factores asociados en mujeres que tienen sexo con mujeres

ABSTRACT Objective: to describe the prevalence of bacterial vaginosis and factors associated among women who have sex with women. Method: cross-sectional, descriptive and analytical study with 150 women. The vaginal microbiota profile was analyzed by microscopic examination of vaginal swabs according to the Gram method. Endocervical samples were collected with cytobrush for the investigation of endocervicitis by Chlamydia trachomatis. The polymerase chain reaction was used to diagnosis Human Papillomavirus infection. Socio-demographic data, sexual behavior and clinical history were obtained through an interview. Logistic regression was performed to identify risk factors independently associated with bacterial vaginosis. Results: among the 150 participants, 71 (47.3%) presented some alteration in the vaginal microbiota, 54 (36.0%) bacterial vaginosis and 12 (8.0%) Flora II. The variable independently associated with bacterial vaginosis was the use of sexual accessories [2.37(1.13-4.97), p=0.022]. Conclusion: the high prevalence of bacterial vaginosis among women who have sex with women indicates the need for screening this population and association between use of sexual accessories and this disease suggests the possibility of transmission of sexual fluids between the partners during the sexual act, which demonstrates the need for educational actions on sexual and reproductive health.

RESUMO Objetivo: descrever a prevalência de vaginose bacteriana e fatores associados em mulheres que fazem sexo com mulheres. Método: trata-se de estudo transversal, descritivo e analítico com 150 mulheres. O padrão de microbiota vaginal foi analisado por microscopia do conteúdo vaginal corado pelo método de Gram. Amostras de secreção endocervical foram coletadas com cytobrush para a pesquisa de endocervicites por Chlamydia trachomatis e para infecção por Papilomavírus Humano por meio de reação em cadeia da polimerase. Dados sociodemográficos, de comportamento sexual e de história clínica foram obtidos por entrevista. Regressão logística foi realizada para identificar fatores de risco independentemente associados à vaginose bacteriana. Resultados: dentre as 150 participantes, 71 (47,3%) tinham alguma alteração da microbiota vaginal, 54 (36,0%) vaginose bacteriana e 12 (8,0%) Flora II. A variável independentemente associada com vaginose bacteriana foi o uso de acessórios sexuais [2,37(1,13-4,97), p=0,022]. Conclusão: a elevada prevalência de vaginose bacteriana entre mulheres que fazem sexo com mulheres aponta a necessidade de rastreio nessa população. O uso de acessórios sexuais associado a esse agravo sugere a possibilidade de transmissão de fluidos sexuais entre as parceiras durante o ato sexual, o que demonstra necessidade de ações de educação em saúde sexual e reprodutiva.

RESUMEN Objetivo: describir la prevalencia de la vaginosis bacteriana y los factores asociados en mujeres que tienen sexo con mujeres. Método: se trata de un estudio transversal, descriptivo y analítico realizado entre 150 mujeres. El patrón de microbiota vaginal se analizó por microscopía del contenido vaginal teñido por el método de Gram. Se recolectaron muestras de secreción endocervical con un citocepillo para investigar la endocervicitis por Chlamydia trachomatis y la infección por el Virus del Papiloma Humano mediante la reacción en cadena de la polimerasa. De la entrevista se obtuvieron datos sociodemográficos, de comportamiento sexual y del historial clínico. Se llevó a cabo una regresión logística para identificar factores de riesgo asociados independientemente a la vaginosis bacteriana. Resultados: entre las 150 participantes, el 71 (47,3%) tenía alteración de la microbiota vaginal, el 54 (36,0%), vaginosis bacteriana y el 12 (8,0%), Flora II. La variable asociada independientemente a la vaginosis bacteriana se debió al uso de accesorios sexuales [2,37(1,13-4,97), p=0,022]. Conclusión: la prevalencia elevada de vaginosis bacteriana entre mujeres que tienen sexo con mujeres señala la necesidad de estudiar dicha población, y el uso de accesorios sexuales asociado a este agravante sugiere la posibilidad de transmisión de fluidos sexuales entre las compañeras durante el acto sexual, razón por la cual deben llevarse a cabo acciones de educación en salud sexual y reproductiva.
