Disorders or Differences of Sex Development? Views of Affected Individuals on DSD Terminology

Family functioning in adolescents and young adults with differences of sex development

OBJECTIVE

Family functioning influences various psychosocial outcomes for individuals with pediatric chronic health conditions (e.g., Leeman, J., Crandell, J. L., Lee, A., Bai, J., Sandelowski, M., & Knafl, K. (2016). Family Functioning and the Well-Being of Children With Chronic Conditions: a Meta-Analysis. Research in Nursing & Health, 39, 229-243), but this has not been examined among families of youth with differences of sex development (DSD). The objective of this study was to examine (a) differences in family functioning based on DSD-related and demographic characteristics, (b) the associations between family functioning and psychosocial outcomes, and (c) the moderating effects of current age.

METHODS

Participants were 57 adolescents and 40 young adults (AYA) ages 12-25 years (M  = 16.97) with DSD resulting in atypical genital appearance and/or discordance between phenotypic and chromosomal sex who participated in a cross-sectional study examining psychosocial outcomes. Participants completed the Family Environment Scale, the McMaster Family Assessment Device, the Perceived Acceptance Scale, and outcome measures including the Youth Self-Report/Adult Self-Report and the Connor-Davidson Resilience Scale. Analyses included t-tests and linear regressions with moderation effects.

RESULTS

AYA reported better family functioning if they were diagnosed at a younger age, learned about their diagnosis at a younger age, had 46, XY karyotype, and identified as male. General family functioning, family conflict, and family acceptance had the strongest associations with psychosocial outcomes. Greater family acceptance was associated with fewer total problems, and this association was stronger for adolescents (ps < .05).

CONCLUSIONS

AYA with certain DSD-related characteristics may demonstrate more adaptive family functioning. Family functioning is strongly associated with psychosocial outcomes for AYA with DSD. Results highlight the importance of developing family-focused interventions to promote psychosocial functioning in AYA with DSD.

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.

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.

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.

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.

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.

Adverse Birth Experiences and Parent Adjustment Associated With Atypical Genital Appearance Due to Differences of Sex Development

OBJECTIVE

Differences/disorders of sex development (DSDs) are rare, congenital conditions involving discordance between chromosomes, gonads, and phenotypic sex and are often diagnosed in infancy. A key subset of parents of children newly diagnosed with a DSD experience clinically elevated distress. The present study examines the relationship between perinatal factors (i.e., gestational age, delivery method) and trajectories of parental adjustment.

METHODS

Parent participants (mothers = 37; fathers = 27) completed measures at baseline, 6- and 12-month follow-up. Multilevel linear regression controlled for clustering of the data at three levels (i.e., time point, parent, and family) and examined the relationship between perinatal factors and trajectories of depressive and anxious symptoms. Two-way interactions between perinatal factors and parent type were evaluated.

RESULTS

Overall depressive and anxious symptoms decreased over time. There were significant interactions between gestational age and parent type for depressive and anxious symptoms, with younger gestational age having a stronger negative effect on mothers vs. fathers. There was a significant interaction between time and gestational age for depressive symptoms, with 36 weeks' gestational age demonstrating a higher overall trajectory of depressive symptoms across time compared to 38 and 40 weeks. Findings for the delivery method were not significant.

CONCLUSIONS

Findings uniquely demonstrated younger gestational age was associated with increased depressive symptoms, particularly for mothers compared to fathers. Thus, a more premature birth may predispose parents of infants with DSD to distress. Psychosocial providers should contextualize early diagnosis-related discussions within stressful birth experiences when providing support.

Public understanding of intersex: an update on recent findings

Surgical interventions on infants with intersex characteristics are considered justified by some on the grounds that they carry a high risk of intolerable stigma. However, public understanding of intersex and its medicalization are under-researched. We review recent qualitative and quantitative studies of the understandings of intersex and its medicalization among people who have no particular professional or public experience of intersex. First, such laypeople reason about clinical dilemmas by drawing on values in similar ways as expert healthcare professionals do. Second, laypeople can over-estimate the utility of current 'umbrella terms,' including intersex, for people with direct familial experience of intersex. Third, beliefs about good and bad effects of medical intervention are affected by framing intersex as either a medical condition or the natural basis for a social identity. Fourth, sexual identity is the best evidenced predictor of opinions about early surgical intervention and its legal limitation on human rights grounds. We argue that possible stigmatizing reactions from the public may not be a solid basis on which to justify early surgical intervention on intersex characteristics.

The psychology of people with variable sex characteristics/intersex

Psychological research on people with variable sex characteristics (VSC)/intersex is broadening from the traditional exploitation of this population to ask nature/nurture questions about sexuality and gender. Healthcare for this population has been highly controversial, prompting research on psychological outcomes, the life-span development of adults with VSC, and distress trajectories of parents of children with VSC. Psychological research on clinical psychologists' roles in multidisciplinary care teams, and on decision making about medical pathways informed by those teams, both inform the evaluation of contemporary healthcare. Research is broadening to consider schoolchildren with VSC, elite athletes with VSC, and public understanding of VSC. The growing interdisciplinary field of intersex studies provides critical resources for psychologists.

Masculinizing surgery in disorders/differences of sex development: clinician- and participant-evaluated appearance and function

OBJECTIVES

To report the long-term follow-up outcomes of masculinizing surgery in disorders/differences of sex development (DSD), including both physicians' and patients' perspectives on appearance and functional outcome, including sexuality.

PATIENTS AND METHODS

In total, 1040 adolescents (age ≥16 years) and adults with a DSD took part in this multicentre cross-sectional clinical study in six European countries in 2014/2015. Of those, 150 living in other than the female gender had some kind of masculinizing surgery: hypospadias repair, orchidopexy, breast reduction and/or gonadectomy. The study protocol included medical data collection, an optional genital examination, and patient-reported outcomes including satisfaction with appearance and current sexual functioning.

RESULTS

Diagnoses included partial and mixed gonadal dysgenesis (45,XO/46,XY; n = 38), Klinefelter syndrome/46,XX males (n = 57), and various 46,XY DSDs (n = 42; e.g. partial androgen insensitivity syndrome, severe hypospadias) and 13 with other diagnoses. Of the participants, 84 underwent hypospadias surgery, 86 orchidopexy, 52 gonadectomy and 32 breast reduction (combinations possible). Physicians evaluated anatomical appearance at genital examination as poor in approximately 11% of patients. After hypospadias surgery, 38% of participants reported that they were (very) dissatisfied with anatomical appearance and 20% with function. The physician and patient evaluations were moderately correlated (r = 0.43).

CONCLUSION

The majority of participants were neutral to satisfied with the appearance and function in the long-term after masculinizing surgery. Given the initial severe phenotype and a risk of unsatisfactory results after masculinizing surgery in DSD, treatment should be handled by experienced multidisciplinary teams in order to optimize the postoperative results.

Differences of sex development in the newborn: from clinical scenario to molecular diagnosis

Differences/disorders of sex development (DSD) are defined as a group of congenital conditions in which the development of chromosomal, gonadal or anatomical sex is atypical. The incidence of DSD is 1:4500 births. The current classification divides DSDs into 3 categories according to chromosomal sex: 46,XX DSD, 46,XY DSD and sex chromosome DSD. DSD phenotypes can be concordant with the genotype (apparently normal external genitalia associated with gonadal dysgenesis), or can range from simply hypospadias to completely masculinised or feminised genitalia with a discordant karyotype. Numerous genes implicated in genital development have been reported. The search of genetic variants represents a central element of the extended investigation, as an improved knowledge of the genetic aetiology helps the immediate and long-term management of children with DSDs, in term of sex of rearing, hormone therapy, surgery, fertility and cancer risk. This review aims to assess the current role of molecular diagnosis in DSD management.

Early Genital Surgery in Disorders/Differences of Sex Development: Patients' Perspectives

Controversy continues over a proposed moratorium on elective genital surgery in childhood for disorders/differences of sex development (DSD). Empirical evidence on patient preference is needed to inform decision-making. We conducted a multicentre survey by cross-sectional questionnaire in 14 specialized clinics in six European countries. The sample comprised 459 individuals (≥ 16 years) with a DSD diagnosis, including individuals with congenital adrenal hyperplasia (CAH) (n = 192), XY DSD with prenatal androgen effect (A) (n = 150), and without (nA) (n = 117). Main outcome measures were level of agreement with given statements regarding genital surgery, including clitoris reduction, vaginoplasty, and hypospadias repair. A total of 66% of individuals with CAH and 60% of those with XY DSD-A thought that infancy or childhood were the appropriate age for genital surgery. Females with XY DSD were divided on this issue and tended to prefer vaginoplasty at a later age (XY DSD-A 39%, XY DSD-nA 32%). A total of 47% of males preferred early hypospadias surgery. Only 12% (CAH), 11% (XY DSD-A), and 21% (XY DSD-nA) thought they would have been better off without any surgery in childhood or adolescence. Individuals who had early genital surgery were more likely to approve of it. Outcome data failed to support a general moratorium on early elective genital surgery. Participant perspectives varied considerably by diagnostic category, gender, history of surgery, and contact with support groups. Case-by-case decision-making is better suited to grasping the ethical complexity of the issues at stake.Trial registration: German Clinical Trials Register DRKS00006072.

Assessing the health-related management of people with differences of sex development

PURPOSE

Health care requirements and perception of people with differences of sex development (DSD) have changed enormously since the "Chicago Consensus Conference" in 2005. Therefore, new standards of care and evaluation of care have to be developed.

METHODS

We summarize the social and legal approach to care for DSD during the last two decades and report the main results of European research activities.

RESULTS

The last two decades were accompanied by legal and societal discussion regarding how to deal with a nonbinary concept of sex. This leads to the necessity to assess health care requirements for individuals with DSD in an objective manner. We briefly review the results of the recently funded European research projects dealing with health-related issues in DSD like EU COST Action DSD, I-DSD, and dsd-LIFE, and address the compilation of quality indicators that will be needed to benchmark health care provision and health care-related outcomes.

CONCLUSIONS

The benchmarking process has to be implemented among health care providers for individuals with DSD within the European Reference Networks for Rare Conditions.

Applying Single-Cell Analysis to Gonadogenesis and DSDs (Disorders/Differences of Sex Development)

The gonads are unique among the body's organs in having a developmental choice: testis or ovary formation. Gonadal sex differentiation involves common progenitor cells that form either Sertoli and Leydig cells in the testis or granulosa and thecal cells in the ovary. Single-cell analysis is now shedding new light on how these cell lineages are specified and how they interact with the germline. Such studies are also providing new information on gonadal maturation, ageing and the somatic-germ cell niche. Furthermore, they have the potential to improve our understanding and diagnosis of Disorders/Differences of Sex Development (DSDs). DSDs occur when chromosomal, gonadal or anatomical sex are atypical. Despite major advances in recent years, most cases of DSD still cannot be explained at the molecular level. This presents a major pediatric concern. The emergence of single-cell genomics and transcriptomics now presents a novel avenue for DSD analysis, for both diagnosis and for understanding the molecular genetic etiology. Such -omics datasets have the potential to enhance our understanding of the cellular origins and pathogenesis of DSDs, as well as infertility and gonadal diseases such as cancer.

Risk of gonadal neoplasia in patients with disorders/differences of sex development

BACKGROUND

Patients with disorders/differences of sex development (DSD), especially those possessing the Y chromosome, have a higher risk of gonadal germ-cell tumours (GCTs). We aimed to examine the incidence of different types of gonadal neoplasia and associated risk factors.

METHODS

A total of 1040 DSD patients aged ≥16 years participated in a cross-sectional multicentre European study (dsd-LIFE). Data on medical history were gathered from the patients' archival medical documents. A web-based questionnaire was filled out individually by the participants. A physical examination was performed in all, while ultrasonography of gonads was carried out in 214 and semen analysis was performed for 53 patients.

RESULTS

Germ-cell neoplasia was present in 12 % of patients with DSD and in 14 % of those with XY DSD. The highest risk (36 %) was observed in 46,XY patients with gonadal dysgenesis (GD): complete GD (33 %) and partial GD (23 %), but also in mixed GD (8 %) and complete androgen insensitivity syndrome (AIS) (6%). It was not reported in partial AIS, XX male, 46,XX DSD and congenital adrenal hyperplasia, Turner and Klinefelter syndromes, or in androgen biosynthesis defects. Benign sex cord-stromal tumours (Sertoli- and Leydig-cell tumours) were noted only in patients with complete AIS (3.1 %) and Klinefelter syndrome (14.3 %). A relationship between risk factors for GCT and gonadal neoplasia appearance, other than the Y chromosome, was not found.

CONCLUSION

Adult patients with GD and the Y chromosome have the highest risk of GCT and should be kept under thorough medical control and receive special medical follow-up to prevent the development of gonadal tumours.
