The aim of this preliminary research was to establish if there are intersex occurrences in wild freshwater fish in Slovenian rivers and streams. In the first study we evaluated all fish species of both sexes obtained from the river Ljubljanica from its source to mouth. In the second study we focused on the rainbow trout (Oncorhynchus mykiss) and brown trout (Salmo trutta m. fario) males from 30 rivers and streams in different parts of Slovenia. The male gonads were histologically assessed for the presence of oocytes to determine the frequency and degree of intersex...

In the past decade there has been considerable positive change regarding the civil rights and liberties of those from lesbian, gay, bisexual, transgender and intersex (LGBTI) communities. For example, the decriminalisation of homosexuality, the recent recognition of marriage and civil partnerships in some European, American and North and South American and Australasian countries, as well as the passing of anti-discriminatory laws that support equality. While these positive changes are welcomed there are areas that remain a challenge for LGBTI individuals and communities...

Stigma defined as "undesired differentness" (Goffman, 1963) and subtyped as "experienced" or "enacted," "anticipated," and "internalized" has been documented for patients with diverse chronic diseases. However, no systematic data exist on the association of stigma with somatic intersexuality. The current report concerns women with classical congenital adrenal hyperplasia (CAH), the most prevalent intersex syndrome, and provides descriptive data on CAH-related stigma as experienced in the general social environment (excluding medical settings and romantic/sexual partners) during childhood, adolescence, and adulthood...

An increasing number of children are born with intersex variation (IV; ambiguous genitalia/hermaphrodite, pseudohermaphroditism, etc.). Evidence shows that endocrine-disrupting chemicals (EDCs) in the environment can cause reproductive variation through dysregulation of normal reproductive tissue differentiation, growth, and maturation if the fetus is exposed to EDCs during critical developmental times in utero. Animal studies support fish and reptile embryos exhibited IV and sex reversal when exposed to EDCs...

This article examines the discursive construction of female same-sex sexual identities in Nairobi. We identify the discursive forces of "choice," devaluation, and invisibility as influential within Kenyan media representations of lesbian, gay, bisexual, transgender, and intersex citizens. Using creative focus groups and participant observation, we demonstrate how same-sex attracted women in Nairobi resist and rearticulate these discursive forces to assert their identity and agency as individuals and as a queer community...

INTRODUCTION: Tobacco use among lesbian, gay, bisexual, and transgender (LGBT) people is double the general population. Limited evidence suggests high smoking rates among intersex people. Lesbian, gay, bisexual, transgender, and intersex (LGBTI) people are a priority population in Australian health policy, particularly mental health and ageing. Despite associations between smoking and non-communicable diseases relevant to ageing and mental health, LGBTI-targeted smoking cessation interventions in Australia have been limited to people living with HIV...

Xenopus laevis is an important model for detecting feminizing effects of endocrine disrupting chemicals (EDCs) on amphibians because its genetic males can be induced to phenotypic females by estrogenic chemicals. It is crucial that chemical exposures begin at sensitive developmental stages for gonadal sex-reversal in X. laevis. To determine the optimal stages for initiating exposures, we investigated gonadal sex-reversal induced by low concentrations of 17α-ethinylestradiol (EE2) when exposures were initiated at different stages (3/4, 45/46, 48 and 50) until stage 58...

Much has been written on the successful lesbian, gay, bisexual, transgender, and intersex movement in South Africa, and the resulting institutionalization of sexual minority rights. Comparatively less has been written about the forms of activism undertaken specifically by Black lesbians that are not oriented toward legal change. In this article, I assert the need to examine public demonstrations of mourning as an act of Black lesbian resistance to violence in South Africa. Based on in-depth interviews with members of Free Gender, a Black lesbian organization, I argue that members' conceptualizations of mourning as providing community support force a reconsideration of what it means to be human...

In the present study, we investigated the occurrence of intersex condition, histopathological changes in the gonad and endocrine disruptor biomarker responses in Tilapia species (Tilaipia guineensis, Sarotherodon galileaus and Oreochromis niloticus) along the Ogun River, Nigeria. The study sites covered a length of 320 km and a total of 1074 tilapias were collected from three sampling sites (Abeokuta, Isheri and Ikorodu) with different degrees of anthropogenic contamination. Samples were also collected from an upstream putative control site (Igboho) along the Ogun River...

Two foxl2 paralogs, foxl2 (also named foxl2a) and foxl3 (also named foxl2b) were considered as fish-specific duplicates. Both belong to the Forkhead box family of transcription factors, which play important roles in regulating reproduction involved in sexual differentiation and regulation of primordial germ cell and gonadal somatic cell development. We isolated the complete foxl3 cDNA from the rice field eel (Monopterus albus), which undergoes a natural female-to-male sex change via an intersex stage during its life cycle...

Male fish are susceptible to developing intersex, a condition characterized by the presence of testicular oocytes. In the present study, the relationship between intersex and exposure to estrogenic endocrine active contaminants (EACs) was assessed for 2 genera of sport fish, Micropterus and Lepomis, at 20 riverine sites. Seasonal trends and relationships between EACs and intersex (prevalence and severity) were examined at varying putative sources of EACs throughout North Carolina, identified as 'point', 'non-point' and 'reference' sites...

Intersex people and bodies have been considered incapable of integration into society. Medical interventions on often healthy bodies remain the norm, addressing perceived familial and cultural demands, despite concerns about necessity, outcomes, conduct and consent. A global and decentralised intersex movement pursues simple core goals: the rights to bodily autonomy and self-determination, and an end to stigmatisation. The international human rights system is responding with an array of new policy statements from human rights institutions and a handful of national governments recognising the rights of intersex people...

As we transition our undergraduate biology classrooms from traditional lectures to active learning, the dynamics among students become more important. These dynamics can be influenced by student social identities. One social identity that has been unexamined in the context of undergraduate biology is the spectrum of lesbian, gay, bisexual, transgender, queer, intersex, and asexual (LGBTQIA) identities. In this exploratory interview study, we probed the experiences and perceptions of seven students who identify as part of the LGBTQIA community...

The adverse outcome pathway (AOP) framework could be helpful for chemical risk assessment and mechanistic research. The aim of the present study was to unravel the mechanism of chlordecone-induced endocrine disruption by illustrating the main molecular initiating event (MIE)/perturbations responsible for the observed effects. In silico simulations were performed to predict the MIE(s), and the results pointed to agonistic interaction with estrogen receptors (ERα, ERβ), androgen receptor (AR), cytochrome P450 (CYP19A) by chlordecone...

Various types of weapon traits found in insect order Coleoptera are known as outstanding examples of sexually selected exaggerated characters. It is known that the sex determination gene doublesex (dsx) plays a significant role in sex-specific expression of weapon traits in various beetles belonging to the superfamily Scarabaeoidea. Although sex-specific weapon traits have evolved independently in various Coleopteran groups, developmental mechanisms of sex-specific expression have not been studied outside of the Scarabaeoidea...

In an effort to address healthcare disparities in lesbian, gay, bisexual, transgender, and queer (LGBTQ) populations, many hospitals and clinics institute diversity training meant to increase providers' awareness of and sensitivity to this patient population. Despite these efforts, many healthcare spaces remain inhospitable to LGBTQ patients and their loved ones. Even in the absence of overt forms of discrimination, LGBTQ patients report feeling anxious, unwelcome, ashamed, and distrustful in healthcare encounters...

Perchlorate is a common aquatic contaminant that has long been known to affect thyroid function in vertebrates, including humans. More recently perchlorate has been shown to affect primordial sexual differentiation in the aquatic model fishes zebrafish and threespine stickleback, but the mechanism has been unclear. Stickleback exposed to perchlorate from fertilization have increased androgen levels in the embryo and disrupted reproductive morphologies as adults, suggesting that perchlorate could disrupt the earliest stages of primordial sexual differentiation when primordial germ cells (PGCs) begin to form the gonad...

The aim of this study was to assess the response of the gonopodium morphology, and the gonadal and liver histology of adult male Cnesterodon decemmaculatus, to sublethal long-term exposure concentrations of 17α-ethinylestradiol (EE2 ). Two experiments were conducted exposing the fish to waterborne concentrations of EE2 ranging from 20 to 200 ng/L for 8, 12 and 16 weeks. Intersex gonads were observed after 8 and 16 weeks in fish exposed to 200 and 100 ng EE2 /L, respectively. Oocytes development from testis germ cells, and replacement of the efferent duct PAS positive secretion surrounding spermatozeugmata by parenchymal tissue and duct structure alterations, were the major observed changes in the gonads...

When a child is born with indeterminate genitalia (so-called intersex or disordered sex development), it becomes very difficult to balance the child's right to determine their own sexual future against the problems of living as a child with an indeterminate gender. Moreover, the initial assignment of gender may prove to be inappropriate and major psychological disturbances in the recipient can arise during adolescence and adult life. The problems of these children were explained to the Australian Senate Committee during its inquiry into intersex surgery in 2013...

Plastic surgery of the vulva for aesthetic reasons is recently gaining popularity in the Western world, as well as in Israel. There are different methods of executing these operations with no meaningful difference in the surgical results and the satisfaction of the patients. There are also more complicated plastic operations, in which the vulva is involved. These are performed in cases of pseudohermaphroditism, various states of intersex, sex change operations and developmental defects of the genitor-urinary systems...
