- Abstract
Disorders/Differences of Sex Development (DSD) encompass congenital conditions with atypical development of chromosomal, gonadal, or anatomical sex. Due to the rarity and complexity of these conditions, strong evidence for clinical practices is scarce, leading to controversies in management. This study, part of a broader project, examines changes over time in the attitudes and beliefs of DSD healthcare providers, focusing on factors contributing to patients' life satisfaction and the influence of medical specialty, gender, and age. Participants included active members of the Pediatric Endocrine Society (PES) and the Societies for Pediatric Urology (SPU) at three time points: 2003–2004 (T1), 2010–2011 (T2), and 2020 (T3). A survey covering predictors of patient life satisfaction, attitudes and beliefs regarding DSD care and outcomes, and participant characteristics was administered. Data were analyzed using descriptive statistics and Generalized Estimating Equations (GEE). Demographics: Participation rates were 56% (PES) and 64.7% (SPU) at T1, 41.1% (PES) and 52.3% (SPU) at T2, and 25.6% (PES) and 51.2% (SPU) at T3. Most participants were male (T1: 70.6%, T2: 61.7%, T3: 70.6%). Factors Affecting Life Satisfaction: Both endocrinologists and urologists ranked "gender identity consistent with assigned sex" as most important. Over time, the endorsement of some factors, such as performing genital surgery at Centers of Excellence, increased, while others, like the influence of prenatal androgen exposure determining gender identity, varied by specialty and gender. Attitudes and Beliefs: Across 18 statements, responses indicated three clusters with strong agreement, moderate agreement, and strong disagreement. Statements on the importance of family background and avoiding gender discordance were consistently endorsed, while those on delaying hypospadias repair until consent were least endorsed. The study highlights variability in beliefs about DSD management over time, influenced by specialty, gender, and age. Despite consensus on some care principles, discrepancies remain, particularly regarding the impact of prenatal androgens and the timing of surgical interventions. These findings underscore the need for regular interdisciplinary communication to align clinical practices with evidence-based guidelines and address subjective beliefs. The survey illustrates evolving perspectives among DSD healthcare providers, emphasizing the need for continued dialogue and education to bridge gaps between clinical evidence and practice. Collaborative efforts, such as the international I-DSD and the U.S. DSD Translational Research Network, are crucial for advancing patient-centered care in this field. [ABSTRACT FROM AUTHOR]

Background: Complete androgen insensitivity syndrome (CAIS) is a rare disorder of sex development characterized by 46,XY karyotype and testes, yet presenting with a complete female phenotype, which is related to mutations in the androgen receptor (AR) gene. Case presentation: We herein present the case of a 14-year-old adolescent with primary amenorrhea and suspected delayed puberty whose diagnostic journey led to the identification of CAIS through the demonstration of a novel AR variant (c.159_207del). Case-based review: Our report encompasses the complexity of CAIS management, focusing on the risk of malignancy, surveillance options, hormone replacement therapy, timing of an eventual gonadectomy, and the psychosocial impact of such a diagnosis. An algorithm has been formulated for the management of CAIS starting in adolescence, highlighting the conservative approach for those patients unwilling to undergo gonadectomy. Conclusions: Primary amenorrhea and delay in puberty development may provide clues, ultimately leading to a diagnosis of CAIS. This review emphasizes the cruciality of a multidisciplinary approach in managing patients with CAIS, needing for an individualized care to optimize the overall outcome. [ABSTRACT FROM AUTHOR]

Purpose: We aimed to identify the genetic causes of hypospadias in children using targeted gene panel sequencing for disorders of sex development (DSD). Materials and Methods: This study included 18 twin boys with hypospadias: seven and two pairs were monozygotic and dizygotic twins, respectively, and six were discordant and three were concordant twins. Targeted gene panel sequencing for 67 known DSD genes was performed. Sequence variants were classified into five different categories, pathogenic, likely pathogenic, variants of uncertain significance, likely benign, and benign, following the American College of Medical Genetics and Genomics Standards and Guidelines. Results: The mean gestational age and birth weight were 35.3±2.0 weeks and 1.96±0.61 kg, respectively, with seven patients being small for gestational age. Hypospadias was present in 12 patients, with posterior type in 33.3% and anterior type in 66.7%. In three families with twins, both siblings had hypospadias. In addition, cryptorchidism was observed in one subject. Surgical correction of hypospadias was performed at a mean age of 22.1 months. Molecular analysis identified 12 different genetic variants, including two pathogenic mutations in the AMH (p.E389*) and SRD5A2 (p.R246Q) genes, found in subjects with hypospadias, respectively. However, only heterozygous mutations were detected. Conclusions: This study did not identify a definitive genetic component contributing to the development of hypospadias; however, the findings suggest that intrauterine growth retardation may play a significant role.

ObjectiveTo investigate the clinical manifestations, molecular genetics and gonadal pathology characteristics of patients with disorders of sex development (DSD), and to summarize the clinical experience of identifying rare diseases from common symptoms.MethodsThe clinical data of 416 patients with DSD diagnosed and treated in the multidisciplinary center of DSD of Guangzhou Women and Children′s Medical Center from May 2018 to August 2023 were retrospectively analyzed, summarized and discussed.ResultsAccording to chromosome karyotype, 416 cases of DSD were classified into three types: 92 cases(22.1%) of abnormal sex chromosome karyotype, 285 cases(68.5%) of 46, XY karyotype and 39 cases(9.4%) of 46, XX karyotype. Among the 92 patients with abnormal sex chromosome karyotype, 59 cases were raised as males, 18 cases (30.5%) complained of short penis with hypospadias and cryptorchidism. The most common karyotype was 45, X/46, XY(58 cases, 63.0%).Among the 285 patients with 46, XY karyotype, 238 cases were raised as males, and 63 cases(26.5%)complained of short penis and hypospadias; 47 cases were raised as females, and 13 cases(27.7%) complained of inguinal mass. A total of 216 patients with 46, XY karyotype were subjected to whole exome gene detection, and 155 cases(71.8%) were found to have molecular pathogenesis with the clinical phenotype. Among the 39 patients with 46, XX karyotype, 19 cases were raised as males, and 8 cases(42.1%) complained of short penis and hypospadias. In the 18 cases of gonad biopsy, 17 cases showed testicular tissue in gonads. Whole exome sequencing was performed in 14 cases. NR5A1 gene heterozygous mutation, SRY gene mutation and SOX3 gene mutation were found in 2 cases, respectively(14.3%). Twenty cases were raised as females, and 14 cases(70.0%) complained of clitoral hypertrophy. Gonad biopsy was performed in 8 cases, with 7 cases of ovotestis(87.5%) and 1 case of NR5A1 gene heterozygous mutation(14.3%).ConclusionsThe etiologies of DSD are complex and diverse, and the clinical manifestations are various, which can be manifested as hypospadias, micropenis, cryptorchidism and other common symptoms of the urinary system. Different etiologies have different treatment options. Therefore, chromosome karyotype, molecular genetic testing and gonadal pathology can be used to clarify the cause of disease, especially for rare diseases, improve the detection rate, reduce the rate of missed diagnosis, and ensure reasonable treatment, especially sex selection.

Abstract Background Differences in Sex Development (DSD) is a heterogeneous group of congenital alterations that affect inner and/or outer primary sex characters. Although these conditions do not represent a mortality risk, they can have a severe psycho-emotional impact if not appropriately managed. The genetic changes that can give rise to DSD are diverse, from chromosomal alterations to single base variants involved in the sexual development network. Epidemiological studies about DSD indicate a global frequency of 1:4500–5500, which can increase to 1:200–300, including isolated anatomical defects. To our knowledge, this study is the first to describe epidemiological and genetic features of DSD in a cohort of Mexican patients of a third-level care hospital. Methods Descriptive and retrospective cross-sectional study that analyzed DSD patients from 2015 to 2021 attended a Paediatric Hospital from Mexico City. Results One hundred one patients diagnosed with DSD were registered and grouped into different entities according to the Chicago consensus statement and the diagnosis defined by the multidisciplinary group. Of the total, 54% of them belong to the chromosomal DSD classification, 16% belongs to 46, XX and 30% of them belongs to the 46, XY classification. Conclusion The frequency for chromosomal DSDs was consistent with the literature; however, we found that DSD 46, XY is more frequent in our cohort, which may be due to the age of the patients captured, the characteristics of our study population, or other causes that depend on the sample size.

Background:DHX37 is an autosomal gene responsible for encoding a helicase from the DExD/H-box family that plays an essential role in ribosome biogenesis. Variants in this gene were previously reported in two different phenotypes: neurodevelopmental disorders and disorders/differences of sex development (DSD). Particularly for the DSD group, variants were mainly reported associated with gonadal dysgenesis and testicular regression syndrome. Summary: Focusing specifically in the DSD group, we revised the 21 DHX37 variants described across a total of 55 cases published in the literature so far. We summarized the most important clinical and molecular features of all cases, trying to have a better comprehensiveness about this gene in the sexual development. Key Messages: The trick question regarding DHX37 is how a helicase involved in basic cell function could have a specific role in testis development. Little is known about the impact of DHX37 variants in DSD individuals. Nevertheless, current research strongly suggests that DHX37 is involved in the male sex development pathway, particularly in testis determination and maintenance. This is evidenced by the predominant assignment of affected individuals as males and the presence of Wolffian structures in most of the cases. Advancements in molecular techniques, such as the generation of induced pluripotent stem cells and the digenic inheritance for DHX37 cases, are also addressed in this paper. This represents the first comprehensive review of all DHX37 variants published in the literature to date. [ABSTRACT FROM AUTHOR]

Biallelic variants of steroidogenic acute regulatory protein (STAR/STARD1) may cause primary adrenal insufficiency and 46,XY disorder of sex development. STAR plays a pivotal role in transporting cholesterol into mitochondria where cholesterol serves as an essential substrate for initiating steroid biosynthesis by its conversion to pregnenolone. Generally, loss-of-function mutations of STAR cause the classic form of lipoid congenital adrenal hyperplasia (LCAH) where steroidogenesis of the adrenal cortex and the gonads is severely affected. By contrast, partial activity of STAR causes a less severe phenotype, the non-classic LCAH, which is characterized by later onset and initial manifestation with isolated adrenal insufficiency only. Disease-causing STAR variants are very rare. Numerous variants of all types have been described worldwide. Prevailing variants have been reported from Japan and Korea and in some population clusters where STAR is more common. Genotype–phenotype correlation is pretty good for STAR variants. While the exact mechanisms of cholesterol transport into mitochondria for steroidogenesis are still under investigation, the important role of STAR in this process is evident by inactivating STAR variants causing LCAH. The mechanism of disease with STAR deficiency is best described by a two-hit model: the first hit relates to impaired cholesterol import into mitochondria and thus lack of substrate for all steroid hormone biosynthesis; the second hit then relates to massive cytoplasmic lipid overload (evidenced by typically enlarged and fatty adrenal glands) leading to cell death and organ destruction. This review summarizes phenotype and genotype characteristics of human STAR variants found through the ClinVar database. [ABSTRACT FROM AUTHOR]

- Abstract
To generate normative data and validate the recently developed, gender-neutral, External Genitalia Score (EGS) in Indian preterm and term neonates and children up to 2 years of age with normal and atypical genitalia. This observational study included 1,040 neonates born between 28 and 42 weeks of gestation and 152 children between 1 and 24 months of age. In addition, 50 children with disorders of sex development (DSD) were also enrolled in the study. The Prader stage/external masculinization score (EMS) (as applicable), anogenital ratio (AGR) and EGS were assessed for all neonates and children with typical and atypical genitalia. Median EGS values in newborn males with typical genitalia were 9.5 at 28–31 weeks, 10.5 at 32–33 weeks, 11 at 34 weeks and 11.5 in males at 35–42 weeks of gestation. For all females with typical genitalia, the EGS was 0. EMS and EGS showed a positive correlation in males with typical genitalia (r=0.421, p=0.000**) and all children with DSD (r=0.857, p=0.000**). Mean AGR in males and females with typical genitalia and those with DSD were 0.52±0.07, 0.31±0.05 and 0.47±0.13, respectively. EGS correlated with AGR in all males with typical genitalia (r=0.107, p=0.008**), and in all children with DSD (r=0.473, p=0.001**). The EGS enables accurate, gender-neutral and comprehensive assessment of external genitalia in Indian neonates and children with typical and atypical genitalia/DSD. Evaluation for DSD is recommended in any child with EGS greater than 0 and ≤10th percentile for gestation or age (10.5 in a term neonate). [ABSTRACT FROM AUTHOR]

Disorders of sex development (DSD) result from intrauterine defects in sex discrimination. The clinical phenotype differs based on the disease type. Cases with ambiguous external genitalia are diagnosed at birth. However, diagnosis of cases with normal-appearing external genitalia may be delayed until puberty. Here, we report a patient with a pelvic mass and a small uterus that was diagnosed by abdominal ultrasound, in addition to the history of primary amenorrhea and physical examination suggested Swyer syndrome, confirmed by genetic karyotyping. Pathological examination of the surgically removed mass revealed dysgerminoma. Until the age of 19, the patient did not have any idea about 46, XY karyotype, and assumed to be a female. The development of dysgerminoma (as a result of the simultaneous presence of gonadal dysgenesis and Y-chromosome) was another challenge that the patient had to deal with. The diagnosis of this patient at an earlier age could have prevented the development of gonadoblastoma, by removal of the streak gonads. By the presentation of this case, we intend to increase the physician's awareness about DSDs; earlier diagnosis may help the patient deal with her disease better and reduce the risk of further complications.

- Abstract
Individuals with differences of sex development (DSD) experience complex, often competing, medical and psychosocial challenges surrounding fertility. The study aimed to characterize how “success” in fertility-related care is conceptualized and attained among individuals with a DSD, their parents or caregivers, healthcare providers, and other stakeholders.Introduction: As part of a larger study, DSD stakeholders (Methods: n = 110) participated in semi-structured interviews covering the clinical care of patients with DSD. Primary questions included “What is a successful outcome in DSD care?” and “How do you achieve it?” with fertility as either a spontaneous or suggested topic of discussion. Transcripts were analyzed utilizing a phenomenological approach. This analysis focuses on the extracted themes related to fertility. Fertility was discussed by 19/24 individuals with DSD, 12/19 parents or caregivers, 35/37 healthcare providers, and 19/30 other stakeholders. Components of successful fertility-related care included (1) specific discussions surrounding the relationship between DSD and fertility potential, options for fertility preservation, and options for non-biologic parenthood; (2) early and repeated introduction of these topics; and (3) consideration of age, developmental maturity, and cultural context on decisions around fertility. Challenges included the lack of fertility outcome data in this population and the irreversibility of gonadectomy. Trade-offs identified included anatomic typicality versus function, fertility preservation versus cancer risk reduction, and balancing the different priorities of stakeholders.Results: A wide range of DSD stakeholders highlighted the importance of addressing fertility concerns in achieving favorable outcomes for individuals with DSD. These stakeholder perspectives should inform fertility-related education, shared decision-making processes, and clinical care. [ABSTRACT FROM AUTHOR]Discussion/Conclusions: - Published

Clinical decision-making for individuals with 46,XY disorders/differences of sex development (DSD) remains unsettled and controversial. The North American DSD Clinician Survey examines the recommendations of a large group of clinical specialists over the last two decades. Active members of the (Lawson Wilkins) Pediatric Endocrine Society and the Societies for Pediatric Urology were invited to respond to a web-based survey at three different timepoints: 2003–2004 (T1), 2010–2011 (T2), and 2019–2020 (T3). Data from 429 participants in T1, 435 in T2, and 264 in T3 were included in this study. The participants were presented with three XY newborn clinical case scenarios—micropenis, partial androgen insensitivity syndrome, and iatrogenic penile ablation—and asked for clinical management recommendations. The main outcomes assessed included the recommended gender of rearing, surgical decision-maker (parent or patient), timing of genital surgery, and age at which to disclose medical details and surgical history to the patient. For all scenarios, the overwhelming majority recommended rearing as male, including a significant increase across timepoints in those recommending a male gender of rearing for the infant with penile ablation. The proportions recommending female gender of rearing declined significantly across timepoints. In general, most recommended parents (in consultation with the physician) serve as surgical decision-makers, but these proportions declined significantly across timepoints. Recommendations on the timing of surgery varied based on the patient's gender and type of surgery. There has been a shift in recommendations away from the "optimal gender policy" regarding gender of rearing and surgical interventions for patients with XY DSD. [ABSTRACT FROM AUTHOR]

OBJECTIVE: Secrecy about a childs difference of sex development (DSD) can lead to internalized shame and stigma. We explored how teenagers and adults with DSD, parents, healthcare providers, and allied professionals value and perceive patient education. METHODS: Stakeholders (n = 110) completed qualitative semi-structured interviews. Relevant themes for educational content were queried and organized. RESULTS: Education was consistently identified as essential to successful outcomes. There was less consistency in how to educate patients. Disagreement existed regarding who should champion the education process. Participants believed medically relevant information should be shared gradually with attention to developmental capacity. Details were lacking regarding how much or what information to share. Participants noted that vetted resources were helpful. Benefits of sharing condition-specific information with patients included supporting their psychosocial development. Barriers included parental resistance to sharing information due to shame/stigma, and cultural and/or family dynamics. CONCLUSIONS: Stakeholders different perspectives regarding patient DSD education warrant future research to focus on the design, evaluation, and implementation of education-focused interventions. PRACTICE IMPLICATIONS: Healthcare providers are responsible for supporting the education of children and teenagers with DSD about their condition. When considering barriers, adopting a cultural or family systems framework can reduce parental resistance and promote open dialogue.

There is growing need to distinguish between sex and gender. While sex is assigned at birth, gender is socially constructed and may not correspond to one's assigned sex. However, in most research studies, sex or gender is assessed in isolation or the terms are used interchangeably, which has implications for research accuracy and inclusivity. We used data from the UK Biobank to quantify the prevalence of disagreement between chromosomal and self-reported sex and identify potential reasons for discordance. Among approximately 200 individuals with sex discordance, 71% of discordances were potentially explained by the presence of intersex traits or transgender identity. The findings indicate that when describing sex- and/or gender-specific differences in health, researchers may be limited in their ability to draw conclusions regarding specific sex and/or gender health information.

Purpose: This case study refers to a case of complete androgen insensitivity syndrome, which presented with amenorrhea back in the past. Case: After conformation of the diagnosis, parents decided not to reveal the condition’s specifics to the patient. At the age of 34 years, she attended our hospital with abdominal swelling, and the following CT scan showed an abdominal mass arising from the ovary of 13 cm x 14 cm size. A laparotomy was done, and a mixture of solid and cystic mass of 20 cm in diameter was found and removed with the ovary. Histopathology of the tumor showed features of testicular seminoma. Conclusion: The aim of this case report is to outline the difficulties in choosing whether and when to do the gonadectomy and whether and how to explain the condition to the patient.

This article argues for a ban on the performance of medically unnecessary genital normalizing surgeries as part of assigning a binary sex/gender to infants with intersex conditions on the basis of autonomy, regardless of etiology. It does this via a dis/analogy with the classic case in bioethics of Jehovah Witness (JW) parents' inability to refuse life‐saving blood transfusions for their minor children. Both cases address ethical medical practice in situations where parents are making irreversible medical decisions on the basis of values strongly held, identity, and relationship‐shaping values—such as religious beliefs or beliefs regarding the inherent value of binary sex/gender—amidst ethical pluralism. Furthermore, it takes seriously—as we must in the intersex case—that the restriction of parents' right to choose will likely result in serious harms to potentially large percentage of patients, their families, and their larger communities. I address the objection that parents' capacity to choose is restricted in the JW case on the basis of the harm principle or a duty to nonmaleficence, given that the result of parent choice would be death. I provide evidence that this is mistaken from how we treat epistemic uncertainty in the JW case and from cases in which clinicians are ethically obligated to restrict the autonomy of nonminor patients. I conclude that we restrict the parents' right to choose in the JW case—and should in the case of pediatric intersex surgery—to secure patient's future autonomy. [ABSTRACT FROM AUTHOR]

- Abstract
The management of Differences of Sex Development (DSD) has evolved considerably in recent years. The questioning of systematic early childhood treatment of DSD requires a better understanding of the outcomes of such treatments and long-term studies are therefore essential to better evaluate the prognosis of DSD. Unfortunately, limitations are numerous including the limited size of the series, the absence of standardized methodology, the evaluation of managements that no longer take place today and the absence of prospective and comparative studies. Despite these difficulties, the purpose of this paper is to present the current data on the long-term follow-up of patients with DSD from the urological, sexual and fertility points of view. Even if it remains difficult at present to establish precise recommendations, we recapitulate the most important points that should drive follow-up of these patients especially the constitution of a multidisciplinary team with a holistic approach, the organization of the transition between adolescence and adulthood, a particular attention to psychological care, a careful communication with the patients and his/her family and the use of standardized data collection systems.

ADRENOGENITAL syndrome ,SEX differentiation disorders ,GENDER identity ,GENDER dysphoria ,CHROMOSOME abnormalities - Abstract
Differences/disorders of sex development (DSD) comprise a large group of rare congenital conditions. 46,XX DSD, excluding congenital adrenal hyperplasia (CAH), represent only a small number of these diseases. Due to the rarity of non-CAH 46,XX DSD, data on this sex chromosomal aberration were confined to case reports or case series with small numbers of patients. As the literature is still relatively sparse, medical data on the long-term effects of these pathologies remain scarce. In this review, we aim to provide an overview of current data on the long-term follow-up of patients with non-CAH 46,XX DSD, by covering the following topics: quality of life, gender identity, fertility and sexuality, global health, bone and cardiometabolic effects, cancer risk, and mortality. As non-CAH 46,XX DSD is a very rare condition, we have no accurate data on adult QoL assessment for these patients. Various factors may contribute to a legitimate questioning about their gender identity, which may differ from their sex assigned at birth. A significant proportion of gender dysphoria has been reported in various series of 46,XX DSD patients. However, it is difficult to give an accurate prevalence of gender dysphoria and gender reassignment in non-CAH 46,XX DSD because of the rarity of the data. Whatever the aetiology of non-CAH 46,XX DSD, fertility seems to be impaired. On the other hand, sexuality appears preserved in 46,XX men, whereas it is impaired in women with MRKH syndrome before treatment. Although there is still a paucity of data on general health, bone and cardiometabolic effects, and mortality, it would appear that the 46,XX DSD condition is less severely affected than other DSD conditions. Further structured and continued multi-center follow-up is needed to provide more information on the long-term outcome of this very rare non-CAH 46,XX DSD condition. [ABSTRACT FROM AUTHOR]

- Abstract
Background: 46,XY sex reversal 11 (SRXY11) [OMIM#273250] is characterized by genital ambiguity that may range from mild male genital defects to gonadal sex reversal in severe cases. DHX37 is an RNA helicase that has recently been reported as a cause of SRXY11. So far, a total of 21 variants in DHX37 have been reported in 58 cases with 46,XY disorders of sex development (DSD). Methods: Whole exome sequencing (WES) was conducted to screen for variations in patients with 46,XY DSD. The subcellular localization of mutant DHX37 proteins was detected by immunofluorescence. And the levels of mutant DHX37 proteins were detected via Western blotting. Results: A novel pathogenic variant of DHX37 was identified in a patient with 46,XY DSD c.2012G > C (p.Arg671Thr). Bioinformatics analysis showed that the protein function of the variant was impaired. Compared with the structure of the wild‐type DHX37 protein, the number of hydrogen bonds and interacting amino acids of the variant protein were changed to varying degrees. In vitro assays revealed that the variant had no significant effect on the intracellular localization of the protein but significantly reduced the expression level of the protein. Conclusions: Our finding further expands the spectrum of the DHX37 variant and could assist in the molecular diagnosis of 46,XY DSD patients. [ABSTRACT FROM AUTHOR]

Several aspects of clinical management of 46,XX congenital adrenal hyperplasia (CAH) remain unsettled and controversial. The North American Disorders/Differences of Sex Development (DSD) Clinician Survey investigated changes, over the last two decades, in clinical recommendations by specialists involved in the management of newborns with DSD. Members of the (Lawson Wilkins) Pediatric Endocrine Society and the Societies for Pediatric Urology participated in a web-based survey at three timepoints: 2003–2004 (T1, n = 432), 2010–2011 (T2, n = 441), and 2020 (T3, n = 272). Participants were presented with two clinical case scenarios—newborns with 46,XX CAH and either mild-to-moderate or severe genital masculinization—and asked for clinical recommendations. Across timepoints, most participants recommended rearing the newborn as a girl, that parents (in consultation with physicians) should make surgical decisions, performing early genitoplasty, and disclosing surgical history at younger ages. Several trends were identified: a small, but significant shift toward recommending a gender other than girl; recommending that adolescent patients serve as the genital surgery decision maker; performing genital surgery at later ages; and disclosing surgical details at younger ages. This is the first study assessing physician recommendations across two decades. Despite variability in the recommendations, most experts followed CAH clinical practice guidelines. The observation that some of the emerging trends do not align with expert opinion or empirical evidence should serve as both a cautionary note and a call for prospective studies examining patient outcomes associated with these changes.

People with innate variations of sex characteristics (also known as intersex traits or disorders or differences of sex development) have any of a wide range of innate physical traits that differ from medical and social norms for female and male bodies. Responses to these physical differences create experiences and risks of stigmatisation, discrimination, violence, and harmful medical practices intended to promote social and familial integration and conformity with gender stereotypes. As is evident globally, the Australian policy response to the existence and needs of people with innate variations of sex characteristics has been largely incoherent, variously framing the population as having disordered sex development in need of "fixing", and a third sex/gender identity group in need of recognition, with only recent engagement by intersex community-controlled civil society organisations. This paper presents an overview of the context and goals of the intersex human rights movement in Australia. Australian intersex community organisations have sought to apply human rights norms and develop new infrastructure to address key health and human rights issues, and necessitating new ways of resolving policy incoherence. Together with human rights, mental health, and public health institutions, they have called for significant changes to medical models of care and reform to research and classification systems. Intersex community organising and resourcing have made a tangible difference. The Australian Capital Territory is the first jurisdiction in the country to move ahead with reforms to clinical practice, including a legislative prohibition of certain practices without personal informed consent, oversight of clinical decision-making, and investment in psychosocial support. A national community-controlled psychosocial support service has also commenced. [ABSTRACT FROM AUTHOR]

ObjectivesThere is a lack of in-depth studies on men's personal experiences of having hypospadias across different aspects of their lives. We therefore aimed to explore the experience of having hypospadias in relation to identity and interpersonal relationships.Subjects and methodsUsing purposive sampling, we included 17 adult men aged 20–49 with variation in hypospadias phenotype. The informants further represented variation in sexuality, relationship status, parental status, and familial cultural context. In-depth interviews were conducted with each informant and the data was analysed using qualitative content analysis.ResultsWe identified four categories. Firstly, The internal experience of hypospadias in relation to being different, being impacted, and being masculine. The remaining three categories related to interpersonal spaces: Intimate spaces, comprising personal relationship with sex, having sex, and being in a relationship; Familial spaces, comprising being a son, and becoming a father; and Public spaces, comprising being hidden, being naked, and peeing. We identified the latent theme varying impact and coping, highlighting differences in experiences relating to both the internal and interpersonal.DiscussionIssues related to hypospadias included struggles with identity and confidence, as well as recurring patterns of social and sexual avoidance. While informants generally related to certain shared experiences, there is large variation in how much hypospadias impacts life, ranging from hardly at all to extensively. This could also fluctuate over time, with puberty and adolescence being an especially sensitive period. Functional and aesthetic outcomes are potentially important for well-being, especially in the case of more severe complications, while personal and interpersonal circumstances play a role in coping and the overall experience of the individual.ConclusionHealthcare, research, and other channels such as patient groups may be able to offer support to those who need it to help more boys and men with hypospadias live unhindered lives.

STUDY OBJECTIVE: Infants with genital development considered atypical for assigned female sex may undergo feminizing genitoplasty (clitoroplasty and/or vaginoplasty) in early life. We sought to identify factors associated with parent/caregiver decisions regarding genitoplasty for their children with genital virilization. DESIGN: Longitudinal, observational study SETTING: Twelve pediatric centers in the United States with multidisciplinary differences/disorders of sex development clinics, 2015-2020 PARTICIPANTS: Children under 2 years old with genital appearance atypical for female sex of rearing and their parents/caregivers INTERVENTIONS/OUTCOME MEASURES: Data on the childs diagnosis and anatomic characteristics before surgery were extracted from the medical record. Parents/caregivers completed questionnaires on psychosocial distress, experience of uncertainty, cosmetic appearance of their childs genitalia, and demographic characteristics. Urologists rated cosmetic appearance. For 58 patients from the study cohort with genital virilization being raised as girls or gender-neutral, we compared these data across 3 groups based on the childs subsequent surgical intervention: (i) no surgery (n = 5), (ii) vaginoplasty without clitoroplasty (V-only) (n = 15), and (iii) vaginoplasty and clitoroplasty (V+C) (n = 38). RESULTS: Fathers and urologists ratings of genital appearance were more favorable in the no-surgery group than in the V-only and V+C groups. Clitorophallic length was greater in the V+C group compared with the V-only group, with substantial overlap between groups. Mothers depressive and anxious symptoms were lower in the no-surgery group compared with the V-only and V+C groups. CONCLUSIONS: Surgical decisions were associated with fathers and urologists ratings of genital appearance, the childs anatomic characteristics, and mothers depressive and anxious symptoms. Further research on surgical decision-making is needed to inform counseling practices.

Background: Complete androgen insensitivity syndrome (CAIS) is a rare disorder of sex development characterized by 46,XY karyotype and testes, yet presenting with a complete female phenotype, which is related to mutations in the androgen receptor (AR) gene. Case presentation: We herein present the case of a 14-year-old adolescent with primary amenorrhea and suspected delayed puberty whose diagnostic journey led to the identification of CAIS through the demonstration of a novel AR variant (c.159_207del). Case-based review: Our report encompasses the complexity of CAIS management, focusing on the risk of malignancy, surveillance options, hormone replacement therapy, timing of an eventual gonadectomy, and the psychosocial impact of such a diagnosis. An algorithm has been formulated for the management of CAIS starting in adolescence, highlighting the conservative approach for those patients unwilling to undergo gonadectomy. Conclusions: Primary amenorrhea and delay in puberty development may provide clues, ultimately leading to a diagnosis of CAIS. This review emphasizes the cruciality of a multidisciplinary approach in managing patients with CAIS, needing for an individualized care to optimize the overall outcome.

Children with innate variations of sex characteristics (also termed differences of sex development or intersex traits) are routinely subjected to medical interventions that aim to make their bodies appear or function more typically female or male. Many such interventions lack clear evidence of benefit, they have been challenged for thirty years, and they are now understood to violate children's rights to bodily autonomy and bodily integrity. In this paper I argue that these persist in part due to epistemic injustices and biomedical authority. Epistemic injustices include limited disclosure of current practices, the systemic marginalisation of community voices and psychosocial professionals, and attempts to discredit or misrepresent testimony. Bioethics has largely failed to change medical practice, and sometimes plays a role in perpetuating epistemic injustices. I find that the development of an intersex movement provides opportunities for epistemic justice and liberation by engaging with other disciplines and promoting oversight of medical decision-making. The paper draws particularly on Australian sources, including internationally influential ethical principles. [ABSTRACT FROM AUTHOR]

- Abstract
In the last 15 years, the care provided for individuals born with differences of sex development (DSD) has evolved, with a strong emphasis on interdisciplinary approaches. However, these developments have not convinced some stakeholders to embrace the current model of care. This care model has also paid insufficient attention to socio-cultural differences and global inequalities.Background: This article is an opinion statement, resulting from in-depth discussions and reflection among clinicians, patients, and family support organizations based in the USA and Europe, where we seek areas of common ground and try to identify opportunities to further develop resources. The product of these conversations is summarized in 10 panels. The corresponding sections provide additional discussion on some of the panel items.Summary: Participants identified areas of agreement, gained a deeper understanding of the reasons behind disagreements on certain matters, and identified the necessary steps to foster future consensus. We offer preliminary recommendations for guiding clinical management and resource allocation. By promoting a broader consensus, we aim to enhance the quality of care and well-being for individuals of all ages who have a DSD. [ABSTRACT FROM AUTHOR]Key Messages: - Published

45,X/47,XYY sexual dysplasia is a disorder of abnormal sexual development due to a rare chromosomal abnormality. We report a case of 45,X/47,XYY mosaicism disorders of sex. The patient presented with primary amenorrhea and masculinization, as well as Turner syndrome. Laparoscopic exploration showed gonadal type for one side the cord -like gonads, one side the ovoid structure. The pathological condition was cryptorchidism type gonadal gland. Bilateral appendages were surgically removed, artificial cycle therapy was given, and then the patient had menstruation. In this paper, we summarized a total of 11 cases, including this case and other ten cases with the female phenotype reported in the literature, seeing a doctor for primary amenorrhea were found. The clinical manifestations, diagnosis and treatment of this disease were summarized as follows: women with phenotype 45,X/47,XYY sexual dysplasia have various clinical manifestations, most of which are Turner syndrome combined with masculinization. It should be early detection and removal of dysplasia gonads, to prevent the occurrence of gonadal tumors and masculine effects. Long-term alternative hormone therapy and psychological counseling should be performed after surgery. [ABSTRACT FROM AUTHOR]

Context Despite high abundance of small indels in human genomes, their precise roles and underlying mechanisms of mutagenesis in Mendelian disorders require further investigation. Objective To profile the distribution, functional implications, and mechanisms of small indels in the androgen receptor (AR) gene in individuals with androgen insensitivity syndrome (AIS). Methods We conducted a systematic review of previously reported indels within the coding region of the AR gene, including 3 novel indels. Distribution throughout the AR coding region was examined and compared with genomic population data. Additionally, we assessed their impact on the AIS phenotype and investigated potential mechanisms driving their occurrence. Results A total of 82 indels in AIS were included. Notably, all frameshift indels exhibited complete AIS. The distribution of indels across the AR gene showed a predominance in the N-terminal domain, most leading to frameshift mutations. Small deletions accounted for 59.7%. Most indels occurred in nonrepetitive sequences, with 15.8% situated within triplet regions. Gene burden analysis demonstrated significant enrichment of frameshift indels in AIS compared with controls (P <.00001), and deletions were overrepresented in AIS (P <.00001). Conclusion Our findings underscore a robust genotype-phenotype relationship regarding small indels in the AR gene in AIS, with a vast majority presenting complete AIS. Triplet regions and homopolymeric runs emerged as prone loci for small indels within the AR. Most were frameshift indels, with polymerase slippage potentially explaining half of AR indel occurrences. Complex frameshift indels exhibited association with palindromic runs. These discoveries advance understanding of the genetic basis of AIS and shed light on potential mechanisms underlying pathogenic small indel events. [ABSTRACT FROM AUTHOR]

Biological sex affects numerous aspects of biology, yet how sex influences different biological processes have not been extensively studied at the molecular level. Caenorhabditis elegans, with both hermaphrodites (functionally females as adults) and males, is an excellent system to uncover how sex influences physiology. Here, we describe a method to isolate large quantities of C. elegans males by conditionally degrading DPY-27, a component of the dosage compensation complex essential for hermaphrodite, but not male, development. We show that germ cells from males isolated following DPY-27 degradation undergo meiosis and spermiogenesis like wild type and these males are competent to mate and sire viable offspring. We further demonstrate the efficacy of this system by analyzing gene expression and performing affinity pull-downs from male worm extracts.

Recently, the so-called Semenya case has brought the problem of gender in sports competitions back into the spotlight. But the fact is that it is not a unique case; rather, it seems a recurrent and inconclusive problem in the history of sports. In this context, the Spanish athlete Martínez-Patiño is an important figure in the history of sport and gender verification, as well as the Indian sprinter Dutee Chand. Martínez-Patiños story thus serves as an important case study of the gender-based anxieties that hampered womens advancement in track and field. Martínez-Patiños experience in Spanish athletics demonstrates the difficulties women faced when attempting to compete in track and field, both in Spain and internationally. Moreover, her experience with gender policies shows the inadequacies of the chromosomal check as a sex marker, as well as the harms caused by the technique. Finally, Martínez-Patiños protest of the International Association of Athletics Federations policy started to dismantle compulsory sex verification used as a criterion for gender eligibility. The publicity surrounding her case pushed the track and field federation to abandon mandatory, on-site testing in 1992. Seven years later, the International Olympic Committee also dropped its compulsory control. Martínez-Patiño became the face of the fight against sex/gender verification in sport and helped dismantle the practice. The case of Martinez-Patiño remains in the collective memory of elite sports and serves as an argument for national and international sporting institutions to reconsider discriminating policies in the context of progress being made for womens rights.

Purpose Androgen insensitivity syndrome (AIS) is a rare X-linked recessive disorder caused by unresponsiveness to androgens because of mutations in the AR gene. Here, we investigated the clinical outcomes and molecular spectrum of AR variants in patients with AIS attending a single academic center. Methods This study included 19 patients with AIS who were confirmed by molecular analysis of AR. Clinical features and endocrinological findings were retrospectively collected, including presenting features, external genitalia, sex of rearing, timing of gonadectomy, pubertal outcomes, and sex hormone levels. Molecular analysis of AR was performed using Sanger, targeted gene panel, or whole-exome sequencing. Results Among all 19 patients, 14 (74%) were classified as having complete AIS (CAIS), whereas 5 (26%) had partial AIS (PAIS). All patients with CAIS, and 3 patients with PAIS were reared as female. One patient with CAIS manifested a mixed germ cell tumor at the age of 30 years. Molecular analysis of AR identified 19 sequence variants; 12 (63%) were previously reported, and the remaining 7 (37%) were novel. Missense mutations were the most common type (12 of 19, 63%), followed by small deletions, nonsense mutations, an insertion, and a splice site mutation. Conclusions Here, we describe the clinical outcomes and molecular characteristics of 19 Korean patients with AIS. Patients with PAIS manifested various degrees of masculinization of the external genitalia. Nonsense and frameshift mutations were frequent in patients with CAIS, whereas patients with PAIS harbored exclusively missense mutations.

Background Intersex individuals experience poor health due, in part, to healthcare avoidance. Nonconsensual intersex surgery may contribute to medical mistrust and avoidance among intersex populations. Purpose The purpose of this study was to explore the relationship between nonconsensual surgery and healthcare avoidance among intersex populations and to examine if medical mistrust mediates this relationship. Methods Data for this cross-sectional study were collected in 2018 and analyzed in 2022. Participants completed a survey collecting information on demographics, medical mistrust, history of nonconsensual surgery, and history of postponing healthcare. One hundred nine participants with valid responses to all regression model variables were included in the study. Multivariable logistic regression models controlling for age, race, and income, examined the relationship between nonconsensual surgery and postponing preventive and emergency healthcare. Mediation analyses of cross-sectional data examined whether medical mistrust mediated the relationship between nonconsensual surgery and postponing preventive and emergency healthcare. Results Mean medical mistrust score was 2.8 (range = 1–4; standard deviation = 0.8), 49.7% of participants had nonconsensual surgery in their lifetime, 45.9% postponed emergency healthcare, and 61.5% postponed preventive healthcare in their lifetime. Nonconsensual surgery was associated with increased odds of delaying preventive (adjusted odds ratio [AOR] = 4.17; confidence interval [CI] = 1.76–9.88; p =.016) and emergency healthcare (AOR = 4.26; CI = 1.71–10.59; p =.002). Medical mistrust mediated the relationship between nonconsensual surgery and delaying preventive (indirect effect = 1.78; CI = 1.16–3.67) and emergency healthcare (indirect effect = 1.66; CI = 1.04–3.30). Conclusions Nonconsensual surgery contributed to healthcare avoidance in this intersex population by increasing medical mistrust. To decrease healthcare avoidance, intersex health promotion interventions should restrict nonconsensual surgery and build trust through trauma-informed care. [ABSTRACT FROM AUTHOR]
