Caring for individuals with a difference of sex development (DSD): a Consensus Statement

Challenges in Care Provision for Children and Adolescents With Differences of Sex Development

OBJECTIVES

The ideal model of care for individuals with Differences of Sex Development (DSD) continues to evolve, with multiple models proposed. This study aimed to explore current care models for individuals with DSD in Australia and New Zealand (NZ) and to identify clinician perceptions of gaps and barriers in current practice.

METHODS

Cross-sectional anonymous online questionnaire, conducted via Research Electronic Data Capture (REDCap) software. Clinicians involved in the diagnosis and management of individuals with DSD in Australia and NZ were contacted through multimodal recruitment approaches. Themes included demographics of respondents, preferred terminology, composition of the DSD multidisciplinary team (MDT) and availability of a database.

RESULTS

Seventy-nine eligible participants from centers in all states and territories of Australia and NZ commenced the survey with 63 complete responses. Almost One-third (31%) of participants are not currently part of a DSD MDT meeting at their center. While three quarters (76%) of respondents identified changes to DSD care over the past 5 years, three quarters (75%) also identified barriers to current care provision. Only 20% of respondents reported psychology being a current part of their MDT and 70% identified psychology as a desired but missing part of their team.

CONCLUSIONS

Responses to the survey identify gaps and barriers to DSD care across Australia and NZ, particularly a lack of psychosocial supports. Current models fall short of international recommendations and services need to explore the reasons for these gaps further.

Role of the pediatrician in the initial management of a newborn with Differences of Sex Development or hypospadias

Caring for newborns with atypical genitalia presents significant challenges. With advancements in prenatal imaging and genetic testing, differences of sex development (DSD) diagnoses are increasingly made before birth through ultrasound and genetic testing, offering opportunities to optimally prepare parents for the birth of their child. Although guidelines recommend management in a specialized DSD center, most newborns who have a DSD are born in settings without immediate access to such expertise. Consequently, local healthcare professionals play a crucial role in the initial assessment, communication, and parental support. This document provides a structured approach to conduct a comprehensive physical examination, evaluate the external genitalia, and initiate appropriate biochemical, hormonal and genetic investigations. Clear, neutral, and supportive language is essential when communicating with parents and has been shown to improve outcomes.

CONCLUSION

A structured clinical approach, early consultation with an expert DSD team, and clear, compassionate communication with the parents are key for the initial management of babies born with a DSD and their parents.

WHAT IS KNOWN

• Differences in sex development (DSD) are rare, complex congenital conditions that often present with atypical genitalia in newborns, requiring early specialized care from a multidisciplinary team. • International and regional guidelines have been developed for the multidisciplinary management of DSD to improve the quality of care.

WHAT IS NEW

• This article offers practical and structured guidance for pediatricians on the initial management of newborns suspected of having Disorders of Sex Development (DSD), both before and after birth. • It emphasizes the significance of a systematic clinical approach, early consultation with experts, and effective communication with parents.

Ovotesticular Disorders of Sexual Development: Diagnostic, Therapeutic, and Evolutionary Aspects

INTRODUCTION

Disorders of sexual development (DSDs) have various etiologies. Our study aims to describe the diagnostic, therapeutic, and evolutionary aspects of ovotesticular disorders of sexual development (OT-DSDs).

PATIENTS AND METHODS

We conducted a retrospective, descriptive study in the pediatric surgery department of the Albert Royer National Children's Hospital Center in Dakar. From January 2019 to December 2023, sixteen children diagnosed and followed for OT-DSD were included in the study. The patient's ages ranged from 3 days to 14 years, with a mean age of three years. We studied the assigned gender, genetic sex, clinical presentation, imaging findings, treatment, and morbidity.

RESULTS

The assigned gender was female in ten patients (62 %), male in five (32 %) and undetermined for one patient. Among those raised as male, two showed signs of female puberty. Nine patients (56 %) presented with an ambiguous phenotype. All of our patients had a 46, XX karyotype. The diagnosis included unilateral ovotesticular DSD in ten cases (63 %), lateral in five cases (31 %), and bilateral in one case (6 %). Three patients were reassigned to the female gender, and two maintained their male assigned gender. Partial gonadectomy was performed in 56 % of the cases. Genitoplasty was performed in nine patients, seven of whom underwent feminizing procedures (78 %). Postoperative morbidity included one case of vaginal stenosis (11 %).

CONCLUSION

Disorders of sex development can be diagnosed late, with patients typically having a 46, XX karyotype. The most common form is unilateral, involving an ovotestis and an ovary. Partial gonadectomy is possible even without intraoperative histological examination.

Genetic and genomic insights into male reproductive tract development

Genetic and genomic analysis continues to drive important insights into male reproductive tract (MRT) development. Here, we briefly review normal MRT development, highlighting recent discoveries of cell types and cellular processes delivered by single-cell sequencing. We report a systematic review of phenotype terms and genes linked to MRT development, identifying 35 terms from the Human Phenotype Ontology associated with 269 unique genes. A parallel review of mouse data revealed differences in the phenotype terms available and the number and identity of genes linked to MRT defects, indicating opportunities for harmonization of knowledge. We used a published single-cell atlas of the developing testis to characterize the regulation of MRT genes across cell types and stages of fetal testis development. Single-cell RNA sequencing data support the conclusion that Leydig cells and Sertoli cells are the primary testicular cell types expressing MRT genes. Furthermore, we find post-conception weeks 6, 8, and 16 to be the key points of upregulation of testicular MRT genes. New advances, especially in imaging and spatially resolved molecular measurements, provide exciting prospects for MRT research and diagnosis, and we expect rapid progress in the coming years. Continued investigation in this space is essential to understand the genetic basis of MRT development and how MRT defects are related to medical outcomes in adult life.

Clinical and genetic diagnosis of first cohort of differences of sexual development in the Iranian population

OBJECTIVES

Differences of sex development (DSD) refer to various congenital conditions affecting the urogenital and hormonal systems. Accurate diagnosis and personalized management are crucial for supporting patients through complex decisions, such as those related to gender identity.

METHODS

This study represents the first comprehensive investigation into DSD in Iran, analyzing patient's clinical and genetic data between 1991 and 2020. Karyotype analysis was performed on 69 patients without a molecular diagnosis, with sex chromosome DSD excluded. Presence of SRY gene evaluated in all sex reversal patients. Whole exome sequencing (WES) was used for 26 undiagnosed patients, revealing pathogenic variants in WT1, NR5A1, DHX37, AR, CYP17A1, and LHCGR genes.

RESULTS

The most common diagnosis was testicular TDSD, identified in 42 patients (60.86 %), with the SRY gene being the primary cause in 36 of these patients. The study highlights the importance of genetic analysis in identifying novel and rare gene variants, particularly within the steroid hormone and gonad differentiation pathways, for both 46, XY and 46, XX DSD.

CONCLUSIONS

These findings emphasize the need for genetic analysis in providing personalized patient care and tailored counseling to help individuals navigate complex decisions, including those involving gender identity.

Global perspective of psychosocial care of patients with differences of sex development from low-income countries

OBJECTIVE

Management of Differences of Sex Development (DSD) is complex and in resource limited settings the psychosexual and psychosocial aspects of DSD care have received limited attention. This review aims to explore recent literature on psychosocial care of DSD in low and upper middle-income countries (L/UMIC).

MATERIALS AND METHODS

Scientific databases were searched and papers on management of DSD were reviewed according to predefined inclusion criteria.

RESULTS

Papers published between January 2010 and July 2024 were screened for eligibility. Seventy studies specifically focusing on psychosexual and psychosocial aspects were identified. In these papers, the following aspects were studied in detail: gender identity, sexual behaviour, quality of life, perception of parents and society, communication and family counselling and socio-cultural and religious aspects.

CONCLUSIONS

The geographical distribution and volume of studies on the psychosexual and psychosocial aspects of DSD in L/UMIC are mostly originating from East-and South-Asia and South & Central America. The findings underscore the need for integrated and culturally sensitive interventions to support the psychosocial well-being of patients and their families affected by DSD within resource-limited contexts. We highly recommend providing specific guidelines recognising the socio-cultural milieu and resource restricted settings. International collaboration providing education and training should be encouraged.

Ambiguous Genitalia Due to 3β-Hydroxysteroid Dehydrogenase Type 2 Deficiency: Clinical, Genetic, and Functional Characterization of Two Novel HSD3B2 Variants

3β-Hydroxysteroid dehydrogenase 2 deficiency (3βHSD2D) is a rare form of congenital adrenal hyperplasia (CAH) with variable clinical presentation. We describe a 46, XY child with ambiguous genitalia and CAH without apparent adrenal insufficiency due to 2 novel heterozygous variants in the HSD3B2 gene (c.779C > T/p.Pro260Leu and c.307 + 1G > A/p.Gly103Asp,fs29X). The disease-causing effect of the novel variants was assessed by genetic and functional studies informing on positive genotype-phenotype correlation. Sex registration was female, and no gender dysphoria has been noted until the present age of 7 years, but psychological assessments have been difficult with a concomitant diagnosis of autism spectrum disorder. Virilization that already progresses prepubertally through peripheral conversion of androgen precursors by 3β-hydroxysteroid dehydrogenase 1 will pose an increasing challenge during puberty.

Satisfaction with a new patient education program for children, adolescents, and young adults with differences of sex development (DSD) and their parents

Objective

Evaluation of the participant satisfaction with a newly developed interdisciplinary, modular education program for children, adolescents, and young adults with differences of sex development (DSD) and their parents.

Methods

The two-day program including tailored medical information, peer consultation and psychological support aimed to improve diagnosis-specific knowledge and empowerment. Post-training satisfaction was measured using an adapted ZUF-8 questionnaire, scoring from 5 (worst) to a maximum of 26 (best) for persons aged 6-17 and from 10 to 40 points for adults, including 2 open-ended questions.

Results

The questionnaire, completed by 89 children (6-13 years), 92 adolescents (14-17 years), 47 young adults (18-24 years), and 345 parents, revealed consistent high satisfaction with the program regardless of age or diagnosis (children 24.4 ± 2.1, adolescents 23.5 ± 2.7; young adults 36.0 ± 4.0, parents 36.6 ± 3.4). Neither sociodemographic factors nor diagnosis burden, shame, or informedness showed relevant associations with satisfaction levels. Participants highlighted exchange and open atmosphere as key satisfaction elements.

Conclusion

Satisfaction with the new education program was high in all examined groups. Implementing it in routine care requires further analysis to determine the program's long-term effects on well-being and knowledge.

Innovation

The first educational program for young people with DSD addressing their specific challenges through inclusive language, an open approach to sex and gender and the inclusion of self-help groups.

Genomic testing for differences of sex development: Practices and perceptions of clinicians

OBJECTIVES

To investigate the approach taken by clinicians involved in the diagnosis and management of individuals with Differences of Sex Development (DSD), particularly with regard to genomic testing, and identify perceived gaps/strengths/barriers in current practice.

DESIGN AND METHODS

An anonymous online survey was developed, with questions exploring demographics, perceptions of genomic testing, availability of genetics services and opinions on the role and utility of genomic testing in DSD. All responses were anonymous. Clinicians involved in the diagnosis and management of individuals with DSD were recruited from relevant societies and departments across Australia and New Zealand.

RESULTS

79 eligible clinicians commenced the survey, with 63 completing it and 16 providing a partial response. The perceived benefit of having a genetic diagnosis for DSD was almost unanimous (97%). Almost half (48%) of respondents reported barriers in genomic testing. 81% of respondents reported they order genomic tests currently. Approaches to genomic testing when faced with four different clinical scenarios varied across respondents. Clinicians perceived genomic testing to be underutilised (median 36 on sliding scale from 0 to 100).

CONCLUSIONS

Despite 97% of respondents reporting benefit of a genetic diagnosis for individuals with DSD, this was not reflected throughout the survey with regard to clinical implementation. When faced with clinical scenarios, the recommendations for genomic testing from respondents was much lower, indicating the discrepancy between perception and clinical practice. Genomic testing in the context of DSD is seen as both beneficial and desired, yet there are multiple barriers impacting its integration into standard clinical care.

DSD-related attitudes and beliefs held by pediatric endocrinologists and urologists: Insights from the North American disorders/differences of sex development (DSD) clinician survey

BACKGROUND

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.

OBJECTIVE

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.

METHODS

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).

RESULTS

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.

DISCUSSION

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.

CONCLUSION

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.

Prevalence of Intersex/Differences in Sex Development and Primary Gonadal Insufficiency in a Pediatric Transgender Population

Purpose

This study aims to assess the prevalence of intersex variations/differences in sex development (I/DSDs), associated adrenal conditions, and primary gonadal insufficiency in children with gender dysphoria.

Methods

We performed a comprehensive review of the medical records for individuals who carried the diagnostic codes for gender dysphoria in addition to intersex and/or other conditions associated with sex steroid variations among patients evaluated by pediatric endocrinologists from 2013 to 2022.

Results

We found that 9 of 612 (1.5%) transmasculine (TM) and 4 of 215 (1.9%) transfeminine patients had detectable I/DSDs. Although most patients were diagnosed with I/DSDs before evaluation of gender dysphoria, 4 of 13 (30.7%) were diagnosed with I/DSDs after being referred to endocrinology for gender dysphoria. In all cases, diagnoses were made by the endocrinologists evaluating for gender dysphoria. An additional 0.7% of TM patients were diagnosed with distinct hyperandrogenic adrenal conditions, and 1% of TM patients were diagnosed with primary ovarian insufficiency.

Conclusion

The low, but clinically relevant, prevalence of I/DSDs, distinct adrenal conditions, and primary gonadal insufficiency in this transgender population supports the need for access to individualized expert medical care. Specifically, multidisciplinary clinics with experience in endocrinology may provide specialized support for the transgender community.

Persistent Müllerian Duct Syndrome with Supernumerary Testicles Due to a Novel Homozygous Variant in the AMHR2 Gene and Literature Review

Introduction: Persistent Müllerian duct syndrome (PMDS) is a rare disorder of sex development (DSD) caused by mutations in the genes coding anti-Müllerian hormone (AMH) or the AMH receptor, characterized by the persistence of Müllerian derivatives, the uterus and/or fallopian tubes, in otherwise normally virilized boys. Testicular regression syndrome is common in PMDS, yet the association with supernumerary testis has been reported in only two patients where genetic testing was not performed. Method: Thus, we report an individual with this particular association caused by a previously unreported homozygous variant in the AMHR2 gene to enable future genotype-phenotype correlations in this rare disorder. In addition, a search of PMDS associated with congenital anomalies reported in the literature was performed to provide a comprehensive overview of this pathology. Results: We present the case of a 13-year-old boy with a history of bilateral cryptorchidism. Two attempts of right orchidopexy were performed at the age of 4 and 5 years. At that time, exploratory laparoscopy identified an intra-abdominal left testicle. In addition, a fibrous structure extending from the left intra-abdominal testicle to the deep inguinal ring (Müllerian duct remnants) and a medially located abdominal mass, bilaterally fixated to the parietal peritoneum (uterine remnant), were detected. The left testicular biopsy revealed immature prepubertal testicular tissue. The uterine remnant was dissected and removed and the left orchidopexy was performed. The karyotype was 46, XY without other numerical or structural chromosomal abnormalities. Reinterventions on the left testicle were performed at the age of 9 and 12 years when a testicular remnant was identified in the left inguinal canal and removed. Three months after left orchidectomy, ultrasound followed by abdominopelvic MRI identified a structure resembling a testis in the left inguinal area. Another surgical exploration was performed, and a mass located outside (lateral) the inguinal canal was found. A biopsy from the suspected mass was performed. The histopathologic examination showed characteristics of immature prepubertal testis. The patient was later referred to our clinic with the suspicion of DSD. Serum AMH and inhibin B were normal. Therefore, the diagnosis of PMDS was suspected. Genetic testing was performed using next-generation sequencing in a gene panel that included AMH and AMHR2 genes. A homozygous variant classified as likely pathogenic in the AMHR2 gene was identified but remains unreported in the literature (NC_000012.11:g.53823315T>C in exon 8 of the AMHR2 gene). Conclusions: A high degree of suspicion and awareness is needed to diagnose this condition in order to avoid iterative surgery. The coexistence of two extremely rare conditions (PMDS and supernumerary testes) has been reported previously in only two patients, yet the association could have a common pathophysiologic background. Our case, reporting a novel AMHR2 variant, highlights the importance of genetic testing in these individuals in order to elucidate a possible genotype-phenotype correlation.

Genetic and Clinical Characteristics of 185 Japanese Children with 46,XY Differences of Sex Development

CONTEXT

46,XY differences of sex development (DSD) are heterogeneous in etiology. The detailed phenotypes of 46,XY DSD patients with monogenic disorders have not been fully elucidated.

OBJECTIVES

To estimate the proportion of monogenic disorders in 46,XY DSD and to characterize the clinical phenotypes of patients with monogenic disorders.

METHODS

A total of 185 Japanese patients (178 families) were enrolled. We sequenced 25 genes related to 46,XY DSD, and assessed the pathogenicity of the identified sequence variants according to the American College of Medical Genetics and Genomics guidelines, supplemented by in silico or in vitro analyses. We analyzed the clinical phenotypes of patients with monogenic disorders, with particular attention to the external or internal genitalia.

RESULTS

We identified 51 patients (47 families) with any monogenic disorders (26%), who possessed pathogenic variants in AR (11%), SRD5A2 (4.5%), NR5A1 (4.0%), SRY (2.8%), WT1 (1.1%), STAR (1.1%), CYP17A1 (0.56%), HSD3B2 (0.56%), or MAP3K1 (0.56%). The proportion of monogenic disorders was significantly higher in subjects with detected Müllerian derivatives (57%) than in those undetected (26%) (P = 0.029), in subjects with female-typical genitalia (91%) than those with ambiguous genitalia (19%) (P < 0.001).

CONCLUSIONS

The proportion of monogenic disorders in Japanese 46,XY DSD patients was approximately 26%. Monogenic disorders were frequent among patients with severe undermasculinization of the external or internal genitalia.

Working towards convergence of the clinical management of differences of sex development/intersex conditions and the human rights framework: A case study

OBJECTIVE

Medical treatments that aim to modify the appearance of the genitals in children who are born with a difference of sex development/intersex (DSD/I*) condition are highly controversial. Human Rights bodies worldwide have argued that such treatments are conflicting with the child's right of personal autonomy and should be legally restricted to the unique situation where the child's physical health is in danger.

DESIGN

We here review the current status of legal initiatives in Europe that have addressed the issue of medical treatments in minors who have a DSD for which they have not been able to give personal informed consent due to their young age.

PATIENTS

The management of a 3 years old child who has congenital adrenal hyperplasia (CAH) and grows up with atypical-looking genitals is discussed.

RESULTS

In spite of extensive psychosocial support to the child and family from birth onwards, and good medical control of CAH, the child develops signs of emotional distress, suspected to be attributable to the genital difference. Our discussions include perspectives from the multidisciplinary DSD team caring for the child, a human rights specialist, and an intersex activist. From our discussions, we conclude that with evolving medical care, new ethical and human rights challenges are raised. A truly holistic human rights approach should not only consider physical but also mental health and psychosocial and psychosexual adaptation of the child to the medical condition, when reflecting on the acceptability of medical treatments in minors for which no personal informed consent can be obtained due to their young age. In addition it is paramount to include the meaningful participation of the child in the clinical management at the earliest possible stage.

CONCLUSIONS

Continued convergence of clinical management and the human rights framework can be realised based on constructive discussions involving all stakeholders, and with the best interest of the child - and adult that they will become - as a common goal.

Sex Assignment in Cases of Ambiguous Genitalia

Ambiguous genitalia is a rare disorder where it is unclear whether an infant's external genitals are male or female. This can be attributed to various internal and external etiologies, such as androgen receptor abnormalities, gonadal abnormalities (such as gonadal dysgenesis or Klinefelter syndrome where a male has an extra X chromosome), enzymatic defects, etc. Correction of such atypical genitalia requires a multidisciplinary approach, including but not limited to surgeons and therapists. It is important to keep in mind that the treatment plan is tailored according to the specific etiology that is causative of the patient's condition, along with the anticipated perioperative and postoperative complications. Islamically speaking, this topic has been addressed in various Islamic literature and disciplines, including guidelines for dealing with this medical condition. Moreover, follow-up of the patient must be done to allow smooth integration into society.

Through the eyes of the parents: a transdiagnostic psychiatric perspective for children with differences of sexual development

PURPOSE

Existing literature lacks data on a subgroup exhibiting psychiatric symptoms below the DSM-5 diagnostic threshold within DSD cases. Our study aims to assess parental knowledge, attitudes toward DSD, and parental perceptions of emotional and behavioral states through a transdiagnostic perspective.

METHODS

The study was conducted with a total of 35 parents of children with DSD. Two groups were established via k-means clustering, based on psychiatric symptomatology levels, derived from The Strength and Difficulties Questionnaire - Parent Form and The Revised Children's Anxiety and Depression Scale - Parent Form: with one group exhibiting lower reported psychiatric symptoms (LPS=27) and the other demonstrating higher psychiatric symptoms (HPS=8) by parents.

RESULTS

Our study found that many parents were hesitant to disclose DSD diagnoses to their children, believing them to be too young to comprehend the information (42.9 %) and that they were unaware of the available support that could be provided by the medical team in disclosing the diagnosis (25.7 %). Our study found no differences in DSM-5 diagnoses between HPS and LPS groups (p>0.05), with ADHD being the most prevalent diagnosis (21.7 %) and a significant overrepresentation of children with a discrepancy between assigned gender at birth and gender upbringing in the HPS group compared to the LPS group (p<0.001).

CONCLUSIONS

Our study emphasizes the necessity of a transdiagnostic approach in psychiatry to move beyond binary conceptualizations and better understand the complexities of individuals with DSD.

Complete Androgen Insensitivity Syndrome in a Young Girl with Primary Amenorrhea and Suspected Delayed Puberty: A Case-Based Review of Clinical Management, Surgical Follow-Up, and Oncological Risk

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.

The Approach to Patients with Disorders of Sex Development (DSD) in the Era of Precision Medicine: The Careful Use of Terminology

The term "DSD" was coined for "disorders of sex development", referring to conditions where the chromosomal, gonadal and/or genital sex is discordant or ambiguous, to replace terms considered imprecise and stigmatizing. Recently, the term "disorder" has been questioned and the term "differences" has been proposed as not stigmatizing, reflecting that the term DSD should be depathologized. In this opinion article, I discuss the importance of using precise technical terminologies amongst healthcare professionals, in the era of "precision medicine", to avoid misleading diagnoses or classifications while being extremely careful to use sensitive terminologies when interacting with patients and their families. On the other hand, I challenge the concept that DSD are not disorders.

Psychosocial Support for Parents, Infants, Children, and Adolescents with Variations of Sex Characteristics: Results from a Pan-European Survey

Early psychosocial support for parents/legal guardians who have children with variations of sex characteristics (VSCs) is crucial in helping avoid potentially harmful medical procedures. Psychosocial support, including peer support, can help parents/legal guardians choose the best care path for their child, and it remains important throughout childhood. However, there is a lack of data on the provision of psychosocial support for families with a child who has VSCs. We sought knowledge about the timing and types of psychosocial support, and the level of implementation of psychosocial support amongst health and psychosocial care professionals and peer supporters. A survey was conducted using a purposive sample of healthcare professionals and members of peer support groups across Europe. A total of 301 responses were received and analysed using descriptive and inferential methods. The survey results showed that psychosocial support primarily addresses diagnostic procedures, medical treatment, and medical interventions. Whilst the majority of healthcare professionals aspired to have psychosocial support provided at the point where a diagnosis of VSCs was suspected, this was only reported as current practice by a minority of respondents. Overall, the survey indicates that there is a need for greater implementation of psychosocial support, and more collaboration between healthcare professionals and peer support groups in caring for children with VSCs and their families.

Perspectives on conducting "sex-normalising" intersex surgeries conducted in infancy: A systematic review

Children with intersex variations continue to be subject to elective, irreversible, "sex-normalising" surgical interventions, despite multiple human rights and legislative bodies calling for their prohibition. Our systematic review aims to understand how medical literature reports rationales for "sex-normalising" surgical interventions conducted in childhood, and how they are contextualised within the medical and social controversy surrounding such interventions. PubMed, EMBASE and CINAHL were searched for English language, peer-reviewed articles reporting primary data on elective, genital, "sex-normalising" surgical interventions conducted on individuals <10 years, published 01/07/2006-30/06/2023 (PROSPERO ID: CRD42023460871). Data on outcomes reported, rationale for the conduct and timing of interventions and acknowledgement of controversy were extracted. Narrative synthesis described rationales and controversy. Risk of bias was assessed using Johanna Briggs Institute Tools. 11,042 records were retrieved, with 71 articles included for analysis. One of the most common outcomes collected in included literature were cosmetic outcomes, primarily reported by surgeons or parents. 62.0% of studies reported no rationale for intervention timing, 39.4% reported no rationale for conduct and 52.1% acknowledged no controversy in intervention conduct. Rationales included parental desire for intervention, anatomical/functional/cosmetic reasons, and a perceived goal of aligning with sex assigned by surgical teams or parents. Controversies addressed included concerns about the quality of interventions, the ethics of intervention conduct and gendered and social considerations. "Sex-normalising" interventions are conducted based largely on rationales that were not adequately supported by evidence, a desire from parents and surgeons to match genital cosmesis typically ascribed to male and female bodies, and a parental desire for intervention conduct. Legislating and medical regulatory bodies should advocate for ending the conduct of irreversible, elective, "sex-normalising" interventions conducted without the full, free and informed consent of the person concerned, to promote and protect the highest attainable standard of health for people with intersex variations.

Impact of luteoma during pregnancy on fetal development and its long-term effects into adulthood

A woman in her 30s presents to the Differences in Sexual Development Programme at a tertiary care academic medical centre with vaginal stenosis and scarring. Her medical history is significant for virilisation in utero due to a maternal luteoma of pregnancy. Laboratory investigations at the time of birth showed elevated androgens in both mother and daughter. During infancy, she underwent clitoroplasty and vaginoplasty for correction of posterior vaginal fusion. She represented as an adult with vaginal stenosis, with associated physical and psychosocial implications. She was not able to insert a tampon or have penetrative intercourse. After examination and shared decision-making, the patient underwent cystoscopy, vaginoscopy and posterior vaginoplasty with the goal to create a normal calibre vagina. Postoperative dilator use was recommended to prevent restenosis of the introitus. In clinic follow-up, the patient was observed to have a normal calibre vagina.

Trajectories of illness uncertainty among parents of children with atypical genital appearance due to differences of sex development

OBJECTIVE

The present study aimed to identify distinct trajectories of parental illness uncertainty among parents of children born with atypical genital appearance due to a difference of sex development over the first year following diagnosis. It was hypothesized that four trajectory classes would emerge, including "low stable," "high stable," "decreasing," and "increasing" classes, and that select demographic, familial, and medical factors would predict these classes.

METHODS

Participants included 56 mothers and 43 fathers of 57 children born with moderate to severe genital atypia. Participants were recruited from eleven specialty clinics across the U.S. Growth mixture modeling (GMM) approaches, controlling for parent dyad clustering, were conducted to examine classes of parental illness uncertainty ratings over time.

RESULTS

A three-class GMM was identified as the best-fitting model. The three classes were interpreted as "moderate stable" (56.8%), "low stable" (33.0%), and "declining" (10.3%). Findings suggest possible diagnostic differences across trajectories.

CONCLUSIONS

Findings highlight the nature of parents' perceptions of ambiguity and uncertainty about their child's diagnosis and treatment the year following their child's birth/diagnosis. Future research is needed to better understand how these trajectories might shift over the course of the child's development. Results support the development of tailored, evidence-based interventions to address coping with uncertainty among families raising a child with chronic health needs.

Recommendations for 46,XY Disorders/Differences of Sex Development Across Two Decades: Insights from North American Pediatric Endocrinologists and Urologists

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.

Evidence for NR2F2/COUP-TFII involvement in human testis development

NR2F2 encodes COUP-TFII, an orphan nuclear receptor required for the development of the steroidogenic lineages of the murine fetal testes and ovaries. Pathogenic variants in human NR2F2 are associated with testis formation in 46,XX individuals, however, the function of COUP-TFII in the human testis is unknown. We report a de novo heterozygous variant in NR2F2 (c.737G > A, p.Arg246His) in a 46,XY under-masculinized boy with primary hypogonadism. The variant, located within the ligand-binding domain, is predicted to be highly damaging. In vitro studies indicated that the mutation does not impact the stability or subcellular localization of the protein. NR5A1, a related nuclear receptor that is a key factor in gonad formation and function, is known to physically interact with COUP-TFII to regulate gene expression. The mutant protein did not affect the physical interaction with NR5A1. However, in-vitro assays demonstrated that the mutant protein significantly loses the inhibitory effect on NR5A1-mediated activation of both the LHB and INSL3 promoters. The data support a role for COUP-TFII in human testis formation. Although mutually antagonistic sets of genes are known to regulate testis and ovarian pathways, we extend the list of genes, that together with NR5A1 and WT1, are associated with both 46,XX and 46,XY DSD.

Approaches in care for people with variations of sex characteristics-focus groups in the European context on the strengths and challenges of multidisciplinary teams

Background

New guidelines in the Consensus Statement on Management of Intersex Disorders by the Lawson Wilkins Pediatric Endocrine Society/European Society for Paediatric Endocrinology Consensus Group 2006 introduced multidisciplinary teams (MDTs) to provide care that involves collaboration between healthcare professionals, parents, and children with variations of sex characteristics (VSC).

Aim

The aim of this study was to examine a neglected but important field of collaboration among healthcare professionals and peer support groups who provide care for people with VSC.

Outcomes

The study outcome was the information obtained regarding the actual composition and collaboration of the multidisciplinary teams caring for children with VSC, including their collaboration with parents, peer support groups, and other care providers.

Methods

In this study we used an exploratory qualitative design based on mixed focus groups (in terms of professional background) and reflexive thematic analysis. Semi-structured focus group interview guides were used to obtain information about the participants' viewpoints on the composition and challenges of, and collaboration between, peer support groups and members of multidisciplinary teams working to care for children with VSC and their parents. Seven focus groups were conducted with healthcare professionals and peer support groups in care teams in Central, Northern, and Western Europe. The data from the focus groups were examined using reflexive thematic analysis.

Results

The participants in the focus groups provided information regarding the use of multidisciplinary and interdisciplinary child- and family-oriented approaches and the strengths and challenges of collaboration and peer support groups. The results showed that the teams used a predominantly multidisciplinary approach and suffered from a lack of psychosocial providers, poor collaboration with peer support groups, and poor implementation of shared decision-making to address the clinical uncertainty of parents and people with VSC.

Clinical Implications

Clinicians should provide more psychosocial support and improve collaboration with peer support groups and nonmedical professionals.

Strengths and Limitations

This study is one of the first qualitative studies to provide information on the collaboration of multidisciplinary teams working to provide care for children with VSC and collaborate with their parents in the European context. However, due to language barriers, the dropout rate of participants, and the under-representation of peer support groups in the sample there was a lack of information on collaboration among healthcare professionals and peer support groups.

Conclusions

The collaboration between MDTs and parents does not involve adequate psychosocial and peer support or shared decision-making to address the uncertainty experienced by children and families when faced with information about variations of sex characteristics.

Healthcare communication satisfaction and psychosocial outcomes in adolescents and young adults with differences of sex development

OBJECTIVES

We examined: (1) healthcare communication satisfaction and psychosocial outcomes (resilience, QoL, and psychological adjustment) in adolescents and young adults (AYA) with differences of sex development (DSD), (2) differences in psychosocial outcomes between those who were highly satisfied and those who were less satisfied, and (3) group differences between adolescents (ages 12-17) and young adults (ages 18-26) regarding associations with healthcare communication and psychosocial outcomes.

METHODS

AYA with DSD across four study sites reported on satisfaction with healthcare communication and psychosocial outcomes. Analyses included descriptive statistics (aim 1), independent samples t-tests (aim 2), and Pearson's correlations (aim 3).

RESULTS

Participants reported high levels of satisfaction with healthcare communication. Higher healthcare communication satisfaction was associated with greater resilience (p = .01), better QoL (p = .02), and fewer internalizing problems (p = .04). For adolescents, higher healthcare communication satisfaction was associated with better psychosocial outcomes (p values ranging from.01-.04). No significant associations were found in the young adult group.

CONCLUSIONS

Satisfaction with healthcare communication is related to positive psychosocial outcomes in adolescents with DSD.

PRACTICE IMPLICATIONS

These data underscore the importance of optimizing communication with families, engaging AYA in early and ongoing discussions about their care, and including psychosocial providers in DSD care.

Development of Quality Indicators to Evaluate the Quality of Care for People with Differences of Sex Development

INTRODUCTION

Achieving evidence-based, high-quality medical care is the overarching goal of healthcare quality management. Quality indicators (QIs) serve as proxies to show whether good quality is reached or not. This article describes the development of QI for the evaluation of healthcare quality in the area of differences of sex development (DSD).

METHODS

Following the model of Donabedian, the aim was to develop QI to assess defined relevant aspects of the quality of structures, processes, and outcomes of care in DSD. Ten DSD clinical centres and two self-advocacy groups in Germany included in the DSDCare project were involved in the development of the QI and a benchmarking system. The development of the QI involved several structured steps: analysis of guidelines and recommendations, literature review, qualitative interviews with key stakeholders in the field of DSD, and patients or their carers. QIs were discussed in a multi-stage systematic consensus process and assessed in terms of their relevance, feasibility, and practicability.

RESULTS

In a multi-stage systematic consensus process involving medical and psychological experts from a range of disciplines, people with DSD and their families, and representatives of self-advocacy groups, we have developed a set of 37 QIs (22 structure, seven process, and eight outcome quality). The QIs serve to evaluate care in the field of DSD and may add to the German criteria for certification of Centres for Rare Conditions formulated by the National Action League for People with Rare Diseases (NAMSE) in this area of expertise.

CONCLUSION

We have succeeded in developing and jointly adopting a set of QIs that consider a wide range of perspectives on the quality of care for people with DSD and their families. These QIs have been found to be relevant, feasible, and practicable, and they are now used for a yearly quality benchmarking in the participating DSD centres.

Queering genomics: How cisnormativity undermines genomic science

Over the past century, genetics and genomics ("genomics") have contributed significantly to our knowledge of human biology and disease. Genomics has also bolstered inaccurate and harmful arguments about "essential" differences between socially defined groups. These purported differences have reinforced class hierarchies and justified the mistreatment of groups such as Black people, Indigenous people, and other people of color and/or people with disabilities. With this history in mind, we explore how genomics is used to reinforce scientifically unsound understandings of the relationship between two fundamental aspects of the human experience: sex and gender. We argue that imprecise, inaccurate practices for collecting data and conducting genomic research have adversely influenced genomic science and can contribute to the stigmatization of people whose sex and/or gender challenge binary expectations. The results have been to preclude transgender and intersex people from accessing high-quality, evidence-based healthcare and to hinder their participation in scientifically sound research. In this perspective, we use the lens of queer theory to render this situation more visible. First, we highlight the theoretical contributions queer theory can make to genomic science. Second, we examine practices in research and clinical genomics that exclude and stigmatize transgender and intersex people. Third, we highlight the ways that many current genomic research practices generate false conclusions that are used to support unjust public policies. We conclude by recommending ways that clinicians and researchers can-and should-harness the scientific, social, and cultural power of genomics to advance knowledge and improve lives across the spectra of sex and gender.

Genital Modifications in Prepubescent Minors: When May Clinicians Ethically Proceed?

When is it ethically permissible for clinicians to surgically intervene into the genitals of a legal minor? We distinguish between voluntary and nonvoluntary procedures and focus on nonvoluntary procedures, specifically in prepubescent minors ("children"). We do not address procedures in adolescence or adulthood. With respect to children categorized as female at birth who have no apparent differences of sex development (i.e., non-intersex or "endosex" females) there is a near-universal ethical consensus in the Global North. This consensus holds that clinicians may not perform any nonvoluntary genital cutting or surgery, from "cosmetic" labiaplasty to medicalized ritual "pricking" of the vulva, insofar as the procedure is not strictly necessary to protect the child's physical health. All other motivations, including possible psychosocial, cultural, subjective-aesthetic, or prophylactic benefits as judged by doctors or parents, are seen as categorically inappropriate grounds for a clinician to proceed with a nonvoluntary genital procedure in this population. We argue that the main ethical reasons capable of supporting this consensus turn not on empirically contestable benefit-risk calculations, but on a fundamental concern to respect the child's privacy, bodily integrity, developing sexual boundaries, and (future) genital autonomy. We show that these ethical reasons are sound. However, as we argue, they do not only apply to endosex female children, but rather to all children regardless of sex characteristics, including those with intersex traits and endosex males. We conclude, therefore, that as a matter of justice, inclusivity, and gender equality in medical-ethical policy (we do not take a position as to criminal law), clinicians should not be permitted to perform any nonvoluntary genital cutting or surgery in prepubescent minors, irrespective of the latter's sex traits or gender assignment, unless urgently necessary to protect their physical health. By contrast, we suggest that voluntary surgeries in older individuals might, under certain conditions, permissibly be performed for a wider range of reasons, including reasons of self-identity or psychosocial well-being, in keeping with the circumstances, values, and explicit needs and preferences of the persons so concerned. Note: Because our position is tied to clinicians' widely accepted role-specific duties as medical practitioners within regulated healthcare systems, we do not consider genital procedures performed outside of a healthcare context (e.g., for religious reasons) or by persons other than licensed healthcare providers working in their professional capacity.

Differences of sex development and surgical decisions: focus group interviews with health care professionals in Norway

Background

Differences of Sex Development (DSD) are congenital conditions where the chromosomal, gonadal and anatomical sex characteristics do not strictly belong to male or female categories, or that belong to both at the same time. Surgical interventions for individuals with DSD remain controversial, among affected individuals, caregivers, and health-care providers. A lack of evidence in support of, for deferring, or for avoiding surgery complicates the decision-making process. This study explores Norwegian health-care professionals' (HCPs) perspectives on decision-making in DSD-related surgeries and the dilemmas they are facing in this process.

Methods

Focus group interviews with 14 HCPs integrated into or collaborating with multidisciplinary DSD teams were analyzed using reflexive thematic analysis.

Results

Two overarching dilemmas shed light on the intricate considerations and challenges that HCPs encounter when guiding affected individuals and caregivers through surgical decision-making processes in the context of DSD. The first theme describes how shared decision-making was found to be influenced by fear of stigma and balancing the interplay between concepts of normality, personal experiences and external expectations when navigating the child's and caregivers' needs. The second theme illuminated dilemmas due to a lack of evidence-based practice. The core concepts within each theme were the dilemmas health-care professionals face during consultations with caregivers and affected individuals.

Conclusion

HCPs were aware of the controversies with DSD-related surgeries. However, they struggled to reconcile knowledge with parents' wishes for surgery and faced dilemmas making decisions in the best interests of the child. This study draws attention to the benefits of increased knowledge on the consequences of performing or withholding surgery as well as incorporating tools enabling shared decision-making between HCPs and affected individuals/caregivers.

Exploratory factor analysis of the Illness Intrusiveness Rating Scale for parents of children with atypical genital appearance due to differences of sex development (DSD)

OBJECTIVE

Illness intrusiveness refers to the subjective cognitive appraisal of a chronic health condition interfering in daily, valued activities and may be highly relevant for parents of children with atypical genital appearance due to differences of sex development (DSD). However, a measure of illness intrusiveness has not been validated for this population. The current study aimed to evaluate the factor structure of the Illness Intrusiveness Scale for Parents (IIS-P) and examine convergent validity.

METHODS

Participants included 102 parents (Mage = 33.39 years, SD = 6.48; 58% mothers) of 65 children (<2 years old) diagnosed with DSD participating in a larger, longitudinal study. Parents completed the IIS-P as well as self-report measures of stigma, and anxious and depressive symptoms. An exploratory factor analysis (EFA) was conducted.

RESULTS

EFA results supported a 1-factor intrusiveness solution (α = .93), as well as a 2-factor solution measuring intrusiveness on daily living (α = .92) and community connectedness (α = .85). The 1-factor solution and both factors of the 2-factor solution demonstrated significant convergent validity with stigma as well as anxious and depressive symptoms.

CONCLUSIONS

Support emerged for both 1- and 2-factor solutions of the IIS-P in parents of children with DSD. The decision to evaluate illness intrusiveness as a total score or to examine the subscales of daily living and community connectedness should be tailored to the unique aims of researchers and clinicians. Future research should conduct a confirmatory factor analysis with both 1- and 2-factor models with larger, more diverse samples of caregivers.

Body image and psychosocial outcomes in youth and young adults with differences of sex development: a multi-method study

OBJECTIVE

Differences of sex development (DSD) can affect the physical health, appearance, and psychosocial functioning of affected individuals, but little is known about how subjective appearance perceptions (body image) impact psychosocial outcomes. This study evaluated body image and its associations with psychosocial outcomes including quality of life, resilience, and psychosocial adjustment.

METHODS

This cross-sectional, multi-method study assessed body image and psychosocial outcomes including quality of life, adjustment, and resilience in 97 youth and young adults with DSD (mean age = 17 ± 3.7 years; 56% assigned female in infancy) using psychometrically sound instruments. A subsample (n = 40) completed qualitative interviews.

RESULTS

Quantitative results indicated that overall, participants were satisfied with their physical appearance, although less so with their primary sex characteristics. Body image dissatisfaction was associated with poorer psychosocial adjustment, quality of life, and resilience. Qualitatively, youth and young adults reported a variety of perceptions, both positive and negative, related to their body image and the impact of living with a DSD condition. Themes identified included appearance management; effects of DSD on body image; diagnostic factors and features; attitudes about diagnosis; and treatment.

CONCLUSIONS

Body image is significantly associated with psychosocial outcomes in youth and young adults with DSD, with qualitative findings highlighting both positive and negative body image experiences. Results have implications for clinical care including screening for appearance concerns, normalization of appearance variations, and intervention development to better support healthy body image and psychosocial functioning in youth and young adults with DSD.

A Pilot Survey of Indian Stakeholders: Parents, Doctors, and Grown-Up Patients of Disorders of Sexual Differentiation on Management Decisions and Associated Gender Dysphoria

Background and Aims

Of late, there are many legal representations from select quarters to halt all medical interventions in children with differences of sex development (DSD). In this survey on management decisions in DSD, we distil the views of Indian stakeholders: parents, physicians, and grown-up patients with DSD on their management decisions to identify decisional satisfaction or gender dysphoria.

Methods

The survey domains included the patient demographics, final diagnosis, decision on the sex of rearing, surgical interventions, opinion of the stakeholders on the preferred age of sex assignment, final sex of rearing, and agreement/disagreement about sex assignment (gender dysphoria).

Results

A total of 106 responses were recorded (66% parents, 34% grown-up patients aged 12-50 years). Among parents, 65/70 (95%) preferred the sex to be assigned soon after birth. All grown-up patients preferred sex to be assigned soon after birth. Regarding decisions on surgery, 74% of physicians and 75% of the grown-up patients felt parents should be allowed to decide interventions. Among Indian parents, 90% felt they should have the right to decide surgery in the best interest of their child for a safe social upbringing. Overall, gender dysphoria among Indian DSD patients was <1% (1/103, 0.97%).

Conclusions

The predominant preference and opinion of major Indian stakeholders (physicians, parents, and grown-up DSD patients) support the existing approach toward DSD management, including early sex assignment and necessary medical intervention.

Preferences in Clinical Care of Individuals With Differences of Sex Development

OBJECTIVES

To identify the most important attributes related to the process of achieving, and outcomes associated with, successful care for differences of sex development (DSD).

METHODS

We developed a best-worst scaling survey administered to 520 DSD stakeholders, including individuals or family members of those with DSD, health care specialists, and patient support and advocacy representatives. Fourteen process-related attributes and 16 outcome-related attributes were identified through qualitative research. We estimated relative importance scores and coefficients from regression analysis to understand the relative importance of attributes and conducted latent class analysis to explore heterogeneity in preferences.

RESULTS

The 3 most important process attributes were (1) good communication between care team and patient/family, (2) care team educated patient/family about condition, and (3) care team incorporates the values of patient/family. The 3 most important outcome attributes were (1) patient satisfaction, (2) patient mental health, and (3) treatment maintains physical health. Latent class analyses showed that respondents had heterogeneous preferences. For process-related attributes, we identified 3 respondent groups: "Patient autonomy and support" (46% of respondents), "Education and care transitions" (18%), and "Shared decision-making" (36%). For outcome-related attributes, we identified 2 respondent groups: "Preserving function and appearance" (59% of respondents) and "Patient health and satisfaction" (41%).

CONCLUSIONS

Outcomes such as patient satisfaction and health were the most important outcome attributes, and good communication and education from the care team were the most important process attributes. Respondents expressed heterogeneous preferences for selected DSD care attributes that providers should consider to improve satisfaction with and quality of DSD care.

Adult outcomes of urinary, sexual functions and fertility after pediatric management of differences in sex development: Who should be followed and how?

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.

Gender determination and long-time follow-up analysis of mixed gonadal dysgenesis

INTRODUCTION

Mixed gonadal dysgenesis (MGD) is a rare disorder of sexual development. The management of MGD is challenging since the disease significantly impacts a patient's growth, hormone balance, and gonadal development. This article used a large population and a long follow-up period for its analysis.

OBJECTIVES

This study aims to summarize the gender determination basis and analyze the long-term follow-up of mixed gonadal dysgenesis.

METHODS

A total of 45 patients' clinical data were summarized and analyzed. Patients were divided by gender. Next, we followed up regarding the occurrence of complications after surgery, the patients' satisfaction with external genitalia appearance, the growth of the patients, counting the surgical pattern the incidence of surgical complications and the development of the patients' growth. All patients included in this study underwent chromosomal karyotype analysis, abdomen exploration, and pathological biopsy. After sex determination, 7 patients who were raised as female underwent clitoroplasty, and bilateral gonadectomy. 38 male patients underwent urethroplasty + one-sided gonadectomy.

RESULTS

Patient follow-up started in the third month after surgery. Female patients reported no surgery-related complications, while 14 male patients showed surgery-related complications. Additionally, 20 male patients (60.6 %) had a lower height compared to normal peers, 12 of which (36.4 %) were lower than the second standard deviation of the height of normal peers.

CONCLUSION

The clinical manifestations of mixed gonadal dysgenesis are variable, and the management is complicated. Children's gonadal function, external genital conditions, psychological evaluation, and parents' wishes should be considered before sex determination. In China, most patients are raised as males with a high incidence of postoperative complications. We found that short stature is a common feature in male patients, thus their height and growth should be carefully supervised. Patients should pay attention to their sexual function and sexual potential during adulthood.

46,XX Differences of Sex Development outside congenital adrenal hyperplasia: pathogenesis, clinical aspects, puberty, sex hormone replacement therapy and fertility outcomes

The term 'differences of sex development' (DSD) refers to a group of congenital conditions that are associated with atypical development of chromosomal, gonadal, and/or anatomical sex. DSD in individuals with a 46,XX karyotype can occur due to fetal or postnatal exposure to elevated amount of androgens or maldevelopment of internal genitalia. Clinical phenotype could be quite variable and for this reason these conditions could be diagnosed at birth, in newborns with atypical genitalia, but also even later in life, due to progressive virilization during adolescence, or pubertal delay. Understand the physiological development and the molecular bases of gonadal and adrenal structures is crucial to determine the diagnosis and best management and treatment for these patients. The most common cause of DSD in 46,XX newborns is congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency, determining primary adrenal insufficiency and androgen excess. In this review we will focus on the other rare causes of 46,XX DSD, outside CAH, summarizing the most relevant data on genetic, clinical aspects, puberty and fertility outcomes of these rare diseases.

Role of NR5A1 Gene Mutations in Disorders of Sex Development: Molecular and Clinical Features

Disorders/differences of sex development (DSDs) are defined as broad, heterogenous groups of congenital conditions characterized by atypical development of genetic, gonadal, or phenotypic sex accompanied by abnormal development of internal and/or external genitalia. NR5A1 gene mutation is one of the principal genetic alterations implicated in causing DSD. This review outlines the role of NR5A1 gene during the process of gonadal development in humans, provides an overview of the molecular and functional characteristics of NR5A1 gene, and discusses potential clinical phenotypes and additional organ diseases due to NR5A1 mutations. NR5A1 mutations were analyzed in patients with 46,XY DSD and 46,XX DSD both during the neonatal and pubertal periods. Loss of function of the NR5A1 gene causes several different phenotypes, including some associated with disease in additional organs. Clinical phenotypes may vary, even among patients carrying the same NR5A1 variant, indicating that there is no specific genotype-phenotype correlation. Genetic tests are crucial diagnostic tools that should be used early in the diagnostic pathway, as early as the neonatal period, when gonadal dysgenesis is the main manifestation of NR5A1 mutation. NR5A1 gene mutations could be mainly associated with amenorrhea, ovarian failure, hypogonadism, and infertility during puberty. Fertility preservation techniques should be considered as early as possible.

Long-term outcomes in non-CAH 46,XX DSD

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.

Psychological support for individuals with differences of sex development (DSD)

OBJECTIVE

Congenital conditions with atypical development of chromosomal, gonadal, or anatomic sex characteristics are referred to as Differences of Sex Development (DSD). Psychosocial care is recommended to be an integral part of clinical management for individuals with DSD. Few studies have examined the perceived need for, utilization of and the opinions of individuals with DSD regarding psychological support.

METHODS

This cross-sectional study was part of a European multicentre study in 14 different medical centres in six countries. In total, 1040 individuals with DSD participated in a patient-reported outcome questionnaire asking about experiences and opinions regarding psychological support in DSD care.

RESULTS

A majority of the participants reported that they had not received psychological support, in childhood and/or adolescence (70.6%, n = 692) nor in adulthood (67.9%, n = 661). Need for psychological support in childhood and/or adolescence was reported by 51.3% (n = 503), need for psychological support in adulthood, was reported by 49.5% (n = 482). The majority (80.2%; n = 718) agreed with the statement that people with DSD should always be offered psychological support. According to 78.7% (n = 697) of the participants, parents of children with DSD should always be offered psychological support.

CONCLUSION

Our findings support the existing consensus that psychological support should be an integral part of DSD care. The discrepancy between received and perceived need for psychological support suggests that individuals with DSD experience barriers to access mental health care services. Psychosocial and psychological services for children, adolescents and adults should therefore be available and offered throughout the lifespan to individuals with DSD.

Objective documentation of hypospadias anatomy with three-dimensional scanning

INTRODUCTION

The absence of a standardized classification of hypospadias hinders understanding of the anatomic differences among patients and the evaluation of outcomes following surgical repair. In working towards a standardized, objective method of recording patients' hypospadias anatomy, we describe our initial experience using a non-invasive three-dimensional scanner.

MATERIAL AND METHODS

An Artec3D Space Spider scanner was used to obtain 3D scans in 29 patients undergoing hypospadias repair. Measurements of the urethral plate width, urethral plate length, glans width, penile shaft length, and penile shaft width were made by 2 pediatric urology attendings and 1 pediatric urology fellow. Measurements were compared and inter-rater reliability was calculated.

RESULTS

A total of 435 measurements were made on 29 successfully generated 3D scans, ranging from distal to proximal hypospadias. The inter-rater reliability of measurements from the generated 3D models shown good inter-rater reliability of urethral plate width (ICC0.87 [95%CI:0.76,0.93]), penile shaft length (ICC0.87 [95%CI:0.70,0.94]) and glans width (ICC0.83 [95%CI:0.68,0.92]), excellent inter-rater reliability of urethral plate length (ICC0.96) and moderate inter-rater reliability of penile shaft width (ICC0.69 [95%CI:0.44,0.84]).

DISCUSSION

There was a high degree of reliability of measurements made across multiple users. Calculation of the ratio of the urethral plate length/total penile shaft length objectively defined the initial position of the urethral meatus. When compared to the 3-dimensional volume of the glans, a more proximally positioned urethral meatus was associated with a lower glans volume.

CONCLUSION

3D scanning offers a rapid, reproducible, and non-invasive method of documenting hypospadias anatomy. The ability to evaluate three dimensional features (i.e. glans volume) offers an exciting opportunities for robust investigation of hypospadias outcomes and further understanding of the relationship between a patient's genotype and phenotype.

Prenatal DEHP exposure induces lifelong testicular toxicity by continuously interfering with steroidogenic gene expression

Background

Epidemiologic studies suggested the association between prenatal di-(2-ethylhexyl) phthalate (DEHP) exposure and disorders of sex development (DSD), adult male disorders, and reproductive aging. Inhibiting testosterone synthesis by interfering with steroidogenic gene expression induces testicular toxicity, however, whether prenatal DEHP exposure induces testicular toxicity through this mechanism remains uncertain.

Methods

C57BL/6JGpt male mice underwent different doses (0, 100, 500, 1,000 mg/kg) of prenatal DEHP exposure during gestational day 10 to delivery day, the testicular toxicity (genital development, testosterone, semen quality, and morphology of testis tissue) in the neonatal, post-puberal and middle-aged stages was observed, and the steroidogenic gene (Lhcgr, Star, Cyp11a1, Cyp17a1, Hsd17b3, and Hsd3b2) expression was analyzed by quantitative polymerase chain reaction (qPCR) and Western blot (WB). The interference of steroidogenic gene expression in TM3 cells after mono-(2-ethylhexyl) phthalate (MEHP) exposure was also explored for verification.

Results

Prenatal DEHP exposure induced immediate testicular injury in the neonatal stage [reduced anogenital distance (AGD) and intratesticular testosterone], DSD in the post-puberal stage (poor genital development), and reproductive aging in the middle-aged stage (obesity, reduced testosterone and semen quality, and atrophic seminiferous tubules), especially in the high dose. Prenatal DEHP exposure continuously interfered with steroidogenic gene expression (Hsd3b2, Hsd17b3) in RNA and protein levels. MEHP inhibited testosterone synthesis of TM3 cells by interfering with steroidogenic gene expression (Hsd3b2, Hsd17b3) in RNA and protein levels.

Conclusions

Prenatal DEHP exposure induces lifelong testicular toxicity by continuously interfering with steroidogenic gene expression, thus indicating the association between prenatal exposure and DSD, adult male disorders, and reproductive aging.

Navigating the complexities of adult healthcare for individuals with variations of sex characteristics: from paediatric emergencies to a sense of abandonment

Intersex people and those with variations of sex characteristics face significant health and social issues. This paper analyses the complexities of adult healthcare for this diverse population, including the root causes of deficiencies in care provision. Many minors with variations of sex characteristics are subjected to irreversible, non-consensual medical interventions, which can have negative effects on their health and wellbeing as adults. This 'emergency' approach to intersex paediatric healthcare has been challenged since the 1990s, but there is still a lack of understanding about how the paradigm affects adult care. This paper aims to raise awareness of the health challenges faced by adults with variations of sex characteristics. It identifies themes related to the challenges associated with accessing appropriate adult care, including the repercussions of childhood treatment, the lack of transitional services and psychological support, the limited general medical knowledge about variations of sex characteristics, and the reluctance to access services due to fear of stigma or past medical trauma. The paper indicates the need for more attention to intersex people's health needs as adults, moving away from attempts to 'fix' them as minors towards approaches which consider and provide for their diverse healthcare needs in a broader temporal context.

A novel MAMLD1 variant in a newborn with hypospadias and elevated 17-hydroxyprogesterone

PURPOSE

Disorders of sex development (DSD) have complex pathogenesis, and evidence suggests an association between MAMLD1 defects and DSD. MAMLD1 is expressed in gonadal tissues and affected males exhibit hypospadias, steroid hormone abnormalities, or gonadal underdevelopment. We performed genetic testing on a newborn patient with severe hypospadias and an elevation of 17-hydroxyprogesterone (17α-OH) for the diagnosis of DSD.

METHODS

Genetic testing of the proband and parents was conducted using whole-exome and Sanger sequencing. The identified variant was transfected into HEK293T cells to assess mutant protein expression using western blot (WB) and into steroidogenic NCI-H295R cells to assess MAMLD1 and CYP17A1 transcript levels using qPCR. Molecular dynamics simulations were performed to construct a structural model and analyze potential biological implications.

RESULTS

A novel heterozygous variant was identified in the proband's MAMLD1, NM_005491.5: c.1619_1637del (p.Gln540Alafs*72), inherited from the mother. In transfected cells, the wild-type and mutant proteins were 86.2 and 68.3 kDa, respectively, indicating the formation of a truncated protein. While MAMLD1 transcription was not affected, CYP17A1 transcription levels decreased with the variant compared to wild-type, suggesting an impact on the transactivation of CYP17A1. The truncated protein exhibited enhanced hydrophobicity, owing to the absence of the C-terminal structural portion, resulting in a looser protein structure.

CONCLUSION

Severe hypospadias in the proband may be attributed to a novel MAMLD1 variant, whereas the 17α-OH elevation might be related to interference with CYP17A1 transcriptional activation. This study expands the spectrum of MAMLD1 variants and underscores the critical role of genetic testing in the diagnosis of DSD.

A life course perspective on Mayer-Rokitansky-Küster-Hauser syndrome: women's experiences and negotiations of living with an underdeveloped uterus and vagina

PURPOSE

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is characterized by the absence or underdevelopment of the uterus and upper part of the vagina. It is usually diagnosed during adolescence, and the present study investigates how women experience and negotiate to live with MRKH syndrome long-term.

METHODS

From January to March 2021, eighteen Danish women with MRKH syndrome participated in semi-structured interviews via video conference. The mean time since diagnosis was 11.5 years. A thematic analysis using the life course framework as a theoretical approach was applied.

RESULTS

The analysis identified the diagnosis as a turning point, that dramatically altered the women's imagined futures. Not conforming to dominant social norms regarding sexuality and pregnancy meant that the women continuously managed and negotiated the meaning and impact of MRKH syndrome in relation to the five principles of the life course perspective: (1) Lifelong development, (2) Timing, (3) Human agency, (4) Linked lives, and (5) Historical time and place.

CONCLUSION

Using the life course framework contributed to a holistic understanding of life with MRKH syndrome by showing how the meaning and consequences of the congenital condition changed over time and in adaptation to gendered and age-related social norms and expectations.IMPLICATIONS FOR REHABILITATIONThe perceived meaning and impact of living with Mayer-Rokitansky-Küster-Hauser syndrome change over time, and women's information and support needs thus change accordinglySensitive, clinical communication is essential when discussing treatment optionsOnline communities may provide support and reduce feelings of loneliness.

Multi-Stakeholder Opinion Statement on the Care of Individuals Born with Differences of Sex Development: Common Ground and Opportunities for Improvement

BACKGROUND

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.

SUMMARY

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.

KEY MESSAGES

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.

Challenges in Transition of Care for People with Variations in Sex Characteristics in the European Context

OBJECTIVE

People with variations in sex characteristics (VSCs) have been receiving inadequate care for many decades. The Chicago consensus statement in 2006 aimed to introduce improved comprehensive care, which would include the transition of care from pediatric to adult services organized by multidisciplinary teams. Yet, the evidence for transitional care is scarce. The aim of this paper is to outline the delivery of transition of care for adolescents and young adults with VSCs.

METHOD

Seven focus groups were conducted with health care professionals and peer support groups by care teams in Central, Northern, and Western Europe. The data from the focus groups were examined using reflexive thematic analysis.

RESULTS

Even though the transition of care has been implemented in the last two decades, it remains inadequate. There are differences among countries, as the quality of care depends on available resources and variations in sex characteristics. Moreover, there are significant hurdles to adequate transition of care, as there is lack of time and funding. The lack of adult care providers and psychosocial support often leaves young adults with VSCs to navigate the health care system alone.

CONCLUSION

The outcome of the study shows that the transition of care is organized through the department of pediatric endocrinology. The quality of care varies due to resources and variations in sex characteristics. A lack of adult specialists, and especially psychosocial support, represents the biggest obstacle for young adults and adults in navigating the health care system and for improvements in the provision of health care to adults. There is a risk of re-traumatization, as adolescents and young adults must often repeat their medical history and educate adult care providers who are insufficiently trained and knowledgeable.
