Clinical evaluation study of the German network of disorders of sex development (DSD)/intersexuality: study design, description of the study population, and data quality

Analyzing body dissatisfaction and gender dysphoria in the context of minority stress among transgender adolescents

BACKGROUND

Gender dysphoria among transgender adolescents has predominantly been examined in relation to body dissatisfaction. While in adult transgender samples, body dissatisfaction is higher than in cisgender controls, this has so far rarely been investigated for adolescents. In the context of a cisnormative society, the impact of influences from the social environment on body dissatisfaction and gender dysphoria has been neglected in research. Therefore, this study aimed to (1) provide a detailed analysis of body dissatisfaction among young transgender people and (2) investigate whether body dissatisfaction and gender dysphoria are associated with experiences of minority stress such as trans hostility and poor peer relations (PPR).

METHODS

The paper presents a cross-sectional study among a sample of transgender adolescents, presenting at a specialized outpatient counseling clinic (N = 99; age M = 15.36, SD = 1.85). First, body dissatisfaction (assessed by the Body-Image-Scale; BIS), was explored and compared to data from a population-based control group of cisgender peers (N = 527; age M = 14.43, SD = 0.97). Second, within a clinic-referred transgender subsample (n = 74), associations between body dissatisfaction and gender dysphoria (measured by Utrecht Gender Dysphoria Scale; UGDS), PPR (measured by the Youth-Self-Report; YSR-R), and trans hostile experiences (assessed in clinical interview) were examined by correlations, t-tests and multivariate regression.

RESULTS

Transgender adolescents reported more body dissatisfaction than cisgender peers. The dissatisfaction with sex characteristics, non-hormonal reactive body regions and the total score for body dissatisfaction were positively related with gender dysphoria. The majority had experienced trans hostility in the present and/or past (54.1%) and PPR (63.5%). More body dissatisfaction was correlated with more PPR regarding visible body parts i.e., hair, overall appearance and muscles, whilst PPR and gender dysphoria were not associated. Transgender adolescents who experienced trans hostility showed higher gender dysphoria and PPR, but not more body dissatisfaction. In multiple regression, trans hostility predicted gender dysphoria, whilst age and PPR predicted body dissatisfaction.

DISCUSSION

Experiences of minority-stress differentially interact with body dissatisfaction and gender dysphoria among transgender adolescents. Social correlates of body dissatisfaction and gender dysphoria must be considered when working with young transgender people.

Clinical characteristics and genetic expansion of 46,XY disorders of sex development children in a Chinese prospective study

Diagnosis and management strategy of disorders of sex development (DSD) are difficult and various due to heterogeneous phenotype and genotype. Under widespread use of genomic sequencing technologies, multiple genes and mechanisms have been identified and proposed as genetic causes of 46,XY DSD. In this study, 178 46,XY DSD patients were enrolled and underwent gene sequencing (either whole-exome sequencing or targeted panel gene sequencing). Detailed clinical phenotype and genotype information were summarized which showed that the most common clinical manifestations were micropenis (56.74%, 101/178), cryptorchidism (34.27%, 61/178), and hypospadias (17.42%, 31/178). Androgen synthesis/action disorders and idiopathic hypogonadotropic hypogonadism were the most frequent clinical diagnoses, accounting, respectively, for 40.90 and 21.59%. From all next-generation sequencing results, 103 candidate variants distributed across 32 genes were identified in 88 patients. The overall molecular detection rate was 49.44% (88/178), including 35.96% (64/178) pathogenic/likely pathogenic variants and 13.48% (24/178) variants of uncertain significance. Of all, 19.42% (20/103) variants were first reported in 46,XY DSD patients. Mutation c.680G>A (p.R227Q) on SRD5A2 (steroid 5-alpha-reductase 2) (36.67%, 11/30) was a hotspot mutation in the Chinese population. Novel candidate genes related to DSD (GHR (growth hormone receptor) and PHIP (pleckstrin homology domain-interacting protein)) were identified. Overall, this was a large cohort of 46,XY DSD patients with a common clinical classification and phenotype spectrum of Chinese patients. Targeted gene panel sequencing covered most of the genes contributing to DSD, whereas whole-exome sequencing detected more candidate genes.

Pathological variants in genes associated with disorders of sex development and central causes of hypogonadism in a whole-genome reference panel of 8380 Japanese individuals

Disorders of sex development (DSD) comprises a congenital condition in which chromosomal, gonadal, or anatomical sex development is atypical. In this study, we screened for pathogenic variants in 32 genes associated with DSDs and central causes of hypogonadism (CHG) in a whole-genome reference panel including 8380 Japanese individuals constructed by Tohoku Medical Megabank Organization. Candidate pathogenic (P) or likely pathogenic (LP) variants were extracted from the ClinVar, InterVar, and Human Gene Mutation databases. Ninety-one candidate pathological variants were found in 25 genes; 28 novel candidate variants were identified. Nearly 1 in 40 (either ClinVar or InterVar P or LP) to 157 (both ClinVar and InterVar P or LP) individuals were found to be carriers of recessive DSD and CHG alleles. In these data, genes implicated in gonadal dysfunction did not show loss-of-function variants, with a relatively high tendency of intolerance for haploinsufficiency based on pLI and Episcore, both of which can be used for estimating haploinsufficiency. We report the types and frequencies of causative variants for DSD and CHG in the general Japanese population. This study furthers our understanding of the genetic causes and helps to refine genetic counseling of DSD and CHG.

Identifying the Resource Needs of Young People with Differences of Sex Development

Adolescents with differences of sex development (DSD) often have complex medical, surgical, and psychological care needs and require age-appropriate resources. This cross-sectional study describes the past and current experiences of adolescents and young adults with DSD and their need for information and support. Participants aged 14−30 years with DSD diagnoses were identified, either from departmental records at the Royal Children’s Hospital (RCH), Melbourne, Australia, or from the private practice of a gynecologist linked to RCH. Anonymized data were collected from a specifically designed online survey. Of the 314 successfully traced patients, 91 (28.9%) completed the survey. Amongst respondents, older age was strongly correlated with higher levels of distress at the time of disclosure (b = 0.67, p < 0.001). People who reported greater understanding of their condition (b = −0.45, p = 0.010) and higher levels of support (b = −0.40, p = 0.003) identified lower levels of current distress. Respondents preferred to receive information from a specialist doctor, GP, or websites and reported information needs being highest during adolescence. Only one in four respondents recalled ever being offered psychological support. A number of perceived barriers to accessing support were identified. Our findings indicate that young people’s information and support needs may be best met by improving online resources, as well as increasing introductions to knowledgeable and appropriate primary care physicians, psychological services, and peer support groups. Further work to promote and increase engagement with psychological and peer support for those with DSD will be important.

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.

The Role of International Databases in Understanding the Aetiology and Consequences of Differences/Disorders of Sex Development

The International Disorders of Sex Development (I-DSD) and International Congenital Adrenal Hyperplasia registry (I-CAH) Registries were originally developed over 10 years ago and have since supported several strands of research and led to approximately 20 peer-reviewed publications. In addition to acting as an indispensable tool for monitoring clinical and patient-centered outcomes for improving clinical practice, the registries can support a wide nature of primary and secondary research and can also act as a platform for pharmacovigilance, given their ability to collect real world patient data within a secure, ethics approved virtual research environment. The challenge for the future is to ensure that the research community continues to use the registries to improve our understanding of Disorders of Sex Development (DSD).

Oestrogen versus androgen in hormone-replacement therapy for complete androgen insensitivity syndrome: a multicentre, randomised, double-dummy, double-blind crossover trial

BACKGROUND

Women with complete androgen insensitivity syndrome (CAIS) after gonadectomy have complained about reduced psychological wellbeing and sexual satisfaction. The aim of this study was to compare the effectiveness of hormone-replacement therapy with either androgen or oestrogen in women with 46,XY karyotype and CAIS after gonadectomy.

METHODS

This national, multicentre, double-blind, randomised crossover trial was performed at three university medical centres and three specialised treatment institutions in Germany. Eligible participants were women aged 18-54 years with 46,XY karyotype, genetically diagnosed CAIS, and removed gonads. Participants were randomly assigned (14:12) by a central computer-based minimisation method to either oestradiol 1·5 mg/day for 6 months followed by crossover to testosterone 50 mg/day for 6 months (sequence A) or to testosterone 50 mg/day for 6 months followed by crossover to oestradiol 1·5 mg/day for 6 months (sequence B). Participants also received oestradiol or testosterone dummy to avoid identification of the active substance. All participants received oestradiol 1·5 mg/day during a 2 months' run-in phase. The primary outcome was mental health-related quality of life, as measured with the standardised German version of the SF-36 questionnaire. Secondary outcomes were psychological wellbeing, as measured with the Brief Symptom Inventory (BSI), sexual function, as measured with the Female Sexual Function Index (FSFI), and somatic effects, such as signs of virilisation and effects on metabolic blood values. The primary analysis included all patients who were available at least until visit 5, even if protocol violations occurred. The safety analysis included all patients who received at least oestradiol during the run-in phase. This trial is registered with the German Clinical Trials Register, number DRKS00003136, and with the European Clinical Trials Database, number 2010-021790-37.

FINDINGS

We enrolled 26 patients into the study, with the first patient enrolled on Nov 7, 2011, and the last patient leaving the study on Jan 23, 2016. 14 patients were assigned to sequence A and 12 were assigned to sequence B. Ten participants were withdrawn from the study, two of whom attended at least five visits and so could be included in the primary analysis. Mental health-related quality of life did not differ between treatment groups (linear mixed model, p=0·794), nor did BSI scores for psychological wellbeing (global severity index, p=0·638; positive symptom distress index, p=0·378; positive symptom total, p=0·570). For the FSFI, testosterone was superior to oestradiol only in improving sexual desire (linear mixed model, p=0·018). No virilisation was observed, and gonadotrophin concentrations remained stable in both treatment groups. Oestradiol and testosterone concentrations changed substantially during the study in both treatment groups. 28 adverse events were reported for patients receiving oestradiol (23 grade 1 and five grade 2), and 38 adverse events were reported for patients receiving testosterone (34 grade 1, three grade 2, and one grade 3). One serious adverse event (fibrous mastopathy) and 20 adverse events (16 grade 1 and four grade 2) were reported during the run-in phase, and 12 adverse events during follow-up (nine grade 1 and three grade 2).

INTERPRETATION

Testosterone was well tolerated and as safe as oestrogen for hormone-replacement therapy. Testosterone can be an alternative hormone substitution in CAIS, especially for woment with reduced sexual functioning.

Quality of Life in Children with Disorders of Sex Development

BACKGROUND/AIMS

Disorders of sex development (DSD) are a heterogeneous group of rare conditions. Evidence-based treatment is challenged by a lack of clinical longitudinal outcome studies. We sought to investigate the quality of life of children with DSD other than congenital adrenal hyperplasia.

METHODS

The participants (aged 6-18 years) were 23 patients raised as males and 7 patients raised as females. Control data were obtained from representatives of the patients' siblings matched for age and gender. The Pediatric Quality of Life InventoryTM Version 4.0 (PedsQL) Generic Core Scales were used as the study tool.

RESULTS

In comparison with the reference data, the patient group had significantly lower overall PedsQL (p < 0.01) and school functioning (p < 0.01) scores. Also, the total PedsQL score was significantly lower in patients with DSD who were of female social sex as compared to the controls who were females. Family income, surgical procedures, degree of virilization, and mode of puberty did not influence the PedsQL scores.

CONCLUSION

This study revealed a poorer quality of life for patients with DSD as compared to the age-matched control group. This highlights the need for a skilled multidisciplinary team to manage this group of patients.

Disorders of sex development: timing of diagnosis and management in a single large tertiary center

BACKGROUND

We describe the phenotypic spectrum and timing of diagnosis and management in a large series of patients with disorders of sexual development (DSD) treated in a single pediatric tertiary center.

METHODS

DSD patients who had visited our tertiary center during the survey period (between 2004 and 2014) were identified based on an ICD-10 inquiry, and their phenotypic and molecular genetic findings were recorded from patient charts.

RESULTS

Among the 550 DSD patients, 53.3% had 46,XY DSD; 37.1% had sex chromosome DSD and 9.6% had 46,XX DSD. The most common diagnoses were Turner syndrome (19.8%, diagnosed at the mean age of 4.7 ± 5.5 years), Klinefelter syndrome (14.5%, 6.8 ± 6.2 years) and bilateral cryptorchidism (23.1%). Very few patients with 46,XY DSD (7%) or 46,XX DSD (21%) had molecular genetic diagnosis. The yearly rate of DSD diagnoses remained stable over the survey period. After the release of the Nordic consensus on the management of undescended testes, the age at surgery for bilateral cryptorchidism declined significantly (P < 0.001).

CONCLUSIONS

Our results show that (i) Turner syndrome and Klinefelter syndrome, the most frequent single DSD diagnoses, are still diagnosed relatively late; (ii) a temporal shift was observed in the management of bilateral cryptorchidism, which may favorably influence patients' adulthood semen quality and (iii) next-generation sequencing methods are not fully employed in the diagnostics of DSD patients.

Development of Health-Related Quality of Life Instruments for Young Children With Disorders of Sex Development (DSD) and Their Parents

Objective

Research in disorders of sex development (DSD) is hindered by a lack of standardized measures sensitive to the experiences of affected children and families. We developed and evaluated parent proxy (children 2-6 years) and parent self-report (children ≤6 years) health-related quality of life (HRQoL) instruments for DSD.

Methods

Items were derived from focus groups and open-ended interviews. Clarity and comprehensiveness were assessed with cognitive interviews. Psychometric properties were examined in a field survey of 94 families.

Results

Measures demonstrated adequate to good psychometrics, including internal consistency, test-retest reliability, convergent validity, and ability to detect known-group differences. Parents reported greatest stress on Early Experiences , Surgery , and Future Concerns scales.

Conclusions

These instruments identify patients' and families' needs, monitor health and quality of life status, and can evaluate clinical interventions. Findings highlight the need for improved psychosocial support during the diagnostic period, better parent-provider communication, and shared decision-making. HRQoL measures are needed for older youth.

Participation of adults with disorders/differences of sex development (DSD) in the clinical study dsd-LIFE: design, methodology, recruitment, data quality and study population

BACKGROUND

dsd-LIFE is a comprehensive cross-sectional clinical outcome study of individuals with disorders/differences of sex development (DSD). This study focuses on various rare genetic conditions characterized by impaired gonadal or adrenal functionality.

METHODS/DESIGN

The study aims to assess quality of life (QoL) as a measure of psychosocial adaptation, psychosexual and mental health aspects as major outcomes. Health status and functioning, medical and surgical therapies, participants' views on health care, psychological and social support, sociodemographic factors and their interrelations will be investigated as factors associated with the outcomes. In addition, ethical considerations in the field of DSD are addressed and previous experiences with health care were gathered. One thousand and forty participants with different DSD conditions were recruited by 14 study centres in 6 European countries (France, Germany, the Netherlands, Poland, Sweden and the United Kingdom) from February 2014 until September 2015. The conditions included were: Turner syndrome (n = 301); 45,X0/46,XY conditions (n = 45); Klinefelter syndrome (n = 218); 47,XYY (n = 1); 46,XY gonadal dysgenesis/ovotestes (n = 63); complete androgen insensitivity (CAIS) (n = 71); partial androgen insensitivity (PAIS) (n = 35) and androgen synthesis disorders (n = 20); severe hypospadias (n = 25); other or non-classified 46,XY DSD (n = 8); 46,XX congenital adrenal hyperplasia (CAH) (n = 226); 46,XX gonadal dysgenesis/ovotestis (n = 21); and 46,XX in males (n = 6). For an add-on study, 121 46,XY male-assigned individuals with CAH due to 21-hydroxylase deficiency were recruited. Mean age of participants' was 32.4 (+/- 13.6 years).

DISCUSSION

Participation was high in conditions not commonly described as DSD, such as Turner and Klinefelter syndromes or CAH. Recruitment of individuals with XY DSD conditions proved to be more difficult. The data collection of PROs resulted in high data quality. Within medical and physical examination data, more missings and/or inaccurate data were found than expected. The European dsd-LIFE study recruited and evaluated the largest cross-sectional sample of individuals with different conditions classified under the term DSD. The data from this large sample will provide a sufficient basis for evidence-based recommendations for improvement of clinical care of individuals affected by a DSD condition.

Health-related quality of life and psychological well-being in adults with differences/disorders of sex development

OBJECTIVE

Rare congenital conditions with incongruence of chromosomal, gonadal and phenotypic sex have been classified as differences/disorders of sex development (DSD). Included in DSD are conditions with diverse genetic aetiology, varying levels of prenatal androgen effects, phenotypes and, subsequently, different medical treatments. Quality of life (QoL) and psychological well-being are indicators of successful psychosocial adaptation to the conditions. We sought to investigate the HRQoL and psychological well-being in this population.

DESIGN

This multicentre clinical evaluation study was part of a German network related to DSD funded by the German Ministry of Science and Education (BMBF 2003 to 2007).

METHODS

To assess health-related quality of life (HRQoL), we used the Short Form Health Survey (SF-36), and for psychological well-being, the Brief Symptom Inventory (BSI). Participants were classified into five groups: females with CAH, females with XY DSD conditions where there is a partial androgen effect (partial androgen insensitivity, mixed/partial gonadal dysgenesis, disorders of androgen biosynthesis), females with XY DSD without androgen effect (complete androgen insensitivity, complete gonadal dysgenesis), males with XY DSD, and individuals with DSD conditions and other gender.

RESULTS

Participants included 110 adults with DSD (age range 17-62). We found a trend of lowered mental HRQoL and significant higher physical HRQoL for participants as compared to the norm. The high physical HRQoL especially applied to females with androgen effect and XY karyotype. Participants reported significant higher psychological distress compared to the norm. Forty-seven participants (42·7%) reported distress in a clinically relevant range on the BSI.

CONCLUSIONS

Although we did not find significant impairments in overall HRQoL, participants reported significant impaired psychological well-being. Specialized interdisciplinary care should focus in particular on psychological issues to ensure good overall health and well-being.

Behavioural Problems in Children with 46XY Disorders of Sex Development

The aim of this study is to determine the behavioural problems of children with 46XY disorders of sex development (DSD) with genital ambiguity and to identify the risk factors that may influence behaviour. The 27 participants (aged 6-18 years) consisted of 21 patients raised as boys and 6 patients raised as girls. Control data were obtained from a representative sibling of each patient who was matched for age and gender. The study tool used was the Child Behaviour Checklist (CBCL), which is a parent-administered questionnaire. The analysis of the behavioural scores revealed that the patient group had poorer scores in the total, externalizing, and internalizing realms. This group also had poorer scores in the anxious-depressed, social, and rule-breaking realms as compared to the control group. In addition, the XY-F group had higher scores (more pathological) than the XY-M group, although the difference in the scores was not statistically significant. A comparison of the prevalence of patients with scores in the clinical range with that of the control group was not statistically significant. These findings support the current recommendations that psychological counselling should be an integral part of the professional support offered to patients with DSD.

Recalled and current gender role behavior, gender identity and sexual orientation in adults with Disorders/Differences of Sex Development

The magnitude of sex differences in human brain and behavior and the respective contributions of biology versus socialization remain a topic of ongoing study in science. The preponderance of evidence attests to the notion that sexual differentiation processes are at least partially hormonally mediated, with high levels of prenatal androgens facilitating male-typed and inhibiting female-typed behaviors. In individuals with Disorders/Differences of Sex Development (DSD), hormonal profiles or sensitivities have been altered due to genetic influences, presumably affecting gender(ed) activity interests as well as gender identity development in a minority of the affected population. While continued postnatal androgen exposure in a number of DSD syndromes has been associated with higher rates of gender dysphoria and gender change, the role of a number of mediating and moderating factors, such as initial gender assignment, syndrome severity and clinical management remains largely unclear. Limited investigations of the associations between these identified influences and gendered development outcomes impede optimization of clinical care. Participants with DSD (n=123), recruited in the context of a Dutch multi-center follow-up audit, were divided in subgroups reflecting prenatal androgen exposure, genital appearance at birth and gender of rearing. Recalled childhood play and playmate preferences, gender identity and sexual orientation were measured with questionnaires and semi-structured interviews. Data were compared to those of control male (n=46) and female participants (n=79). The findings support that (a) prenatal androgen exposure has large effects on (gendered) activity interests, but to a much lesser extent on sexual orientation and that (b) initial gender of rearing remains a better predictor of gender identity contentedness than prenatal androgen exposure, beyond syndrome severity and medical treatment influences. Nonetheless, 3.3% of individuals with DSD in our sample self-reported gender dysphoria from an early age and changed gender, which further underlines the need for thorough long- term follow-up and specific clinical support.

The Youth Health Care measure-satisfaction, utilization, and needs (YHC-SUN)-development of a self-report version of the Child Health Care (CHC-SUN) proxy-measure

BACKGROUND

The transition of health care of youth (age 15-25) with chronic conditions requires the assessment of adolescents' access, use and needs as well as satisfaction with the health services they use. The aim of this study was to test the adolescent adaptation of the parent version "Child Health Care Questionnaire - Satisfaction, Utilization and Needs" (CHC-SUN) concerning its psychometric performance and appropriateness for adolescents and young adults.

METHODS

The Youth Health Care Measure (YHC-SUN) was designed to allow self-report of youth and it was pilot-tested in a small sample using cognitive debriefing. A cross-sectional survey in a sample of youth with chronic conditions in the transition period was carried out.

RESULTS

One hundred eighty-two ambulatory care patients with three conditions participated in the survey. The subscales of the section on satisfaction with care showed excellent internal consistencies, uni-dimensionality and fit to the model of the parent version. There was no impact of gender and education on satisfaction with care. Associations with age, diagnosis, experiences with care and health literacy affecting the satisfaction with care indicate discriminatory and content validity.

CONCLUSIONS

Potential applications of the new instrument are evaluations of health care services for adolescents and young adults using self-reports and evaluations of transition programs and interventions such as patient education.

Psychosocial well-being in Dutch adults with disorders of sex development

OBJECTIVE

Atypical sex development is associated with psychosocial vulnerability. We investigated psychosocial well-being in individuals with disorders of sex development (DSD) and hypothesized that psychosocial well-being was related to degree of genital atypicality at birth.

METHODS

120 male (n=16) and female (n=104) persons with DSD, aged 14-60 years, participated in a follow-up audit on psychosocial well-being. They were stratified in: women with 1) 46,XY and female genitalia, 2) 46,XY or 46,XX and atypical genitalia, and 3) men with 46,XY and atypical genitalia. We used the Illness Cognition Questionnaire (ICQ), Checklist Individual Strength (CIS8R), TNO-AZL Quality of Life questionnaire (TAAQOL), Adult Self-Report (ASR), and the Rosenberg Self-Esteem Scale (RSES).

RESULTS

Data were compared to reference groups. Participants generally were coping well with DSD (ICQ). Women with DSD reported elevated levels of fatigue (CIS8R) and slightly more attention and memory problems (TAAQOL, ASR). Women with atypical genitalia reported more emotional and behavioral problems. On the ASR Rule-breaking Behavior and Antisocial Personality scales, these women had similar scores as reference men. Women with DSD reported a higher self-esteem (RSES). No differences in psychosocial well-being were found between men with DSD and reference men.

CONCLUSION

Individuals with DSD across all diagnostic groups generally reported a good psychosocial well-being. The results further suggest involvement of prenatal androgens in the development of personality traits related to assertiveness and egocentricity. We recommend that individuals with a DSD and their families are involved in decision-making processes and have access to multidisciplinary care.

Subjective need for psychological support (PsySupp) in parents of children and adolescents with disorders of sex development (dsd)

Disorders/diversity of sex development (dsd) is an umbrella term for congenital conditions often diagnosed within childhood. As most parents are unprepared for this situation, psychological support (PsySupp) is recommended. The aim of this study was to analyse the extent to which parents express a need for PsySupp. Three hundred twenty-nine parents of children with dsd were included; 40.4 % of the parents indicated to have a need for PsySupp, only 50 % of this group received it adequately. The diagnoses partial gonadal dysgenesis, partial androgen insensitivity syndrome (pAIS) and disorders of androgen synthesis are associated with a high need for PsySupp in parents (54, 65, and 50 %). Sex assignment surgery neither reduced nor increased the need for PsySupp. Taking a picture, radiography, laparoscopy, gonadal biopsy, gonadectomy and hormonal puberty induction are associated with a high need for PsySupp. There was no association between the need for PsySupp and the parents' perception of the appearance of the genitalia.

CONCLUSION

Having a child with dsd is associated with a high need for PsySupp in parents. In particular, parents of children with XY-dsd with androgen effects other than hypospadias expressed a high need of PsySupp. PsySupp for parents should be an obligatory part of interdisciplinary care to reduce fears and concerns. What is known • In parents, having a child with dsd provokes insecurities and fears. Hence, psychological support is recommended as part of the interdisciplinary care. What is new • This is the first study investigating the subjective need for psychological support in a large sample of parents of children with dsd in Germany. We present data on the subjective need for psychological support of the parents, related diagnoses and factors, which should be considered in psychological counselling.

Quality of Life and Psychological Adjustment of Women Living with 46,XY Differences of Sex Development

BACKGROUND

Progressive care improvement for differences of sex development (DSD), regarding diagnosis communication, psychological, medical and surgical management has been claimed.

AIM OF THE STUDY

To assess clinical management, quality of life (QoL) and the general psychosocial adjustment of individuals with 46,XY DSD. Some differences related to age at diagnosis are investigated.

DESIGN

Cross-sectional study using standardized questionnaires.

POPULATION

Forty-three Caucasian females with 46,XY DSD (self declared diagnoses: complete androgen insensitivity syndrome, n = 34; complete gonadal dysgenesis, n = 1; 5α-reductase deficiency, n = 4; Leydig cell hypoplasia, n = 1; unknown diagnosis, n = 3; age years: 31.5 ± 9.6 [range 18-57 years]).

SETTING

University Hospitals.

METHODS

Subjects were required to fill in questionnaires (ABCL, WHOQOL, dedicated 17-item questionnaire). Academic and socioeconomic data were compared with those of the Italian population. QoL and psychological data were compared with those of a comparison group (46,XX healthy females: n = 43; age, years: 34.5 ± 9.7, range 22-51 years).

RESULTS

Present sample of women living with 46,XY DSD were well adapted and were higher achievers than controls, both in educational and professional life. They showed good QoL, but they appeared less satisfied in psychological and social areas. They had borderline mean scores and statistically higher scores than the comparison group for depression, anxiety, internalizing and externalizing problems. Younger persons living with a 46,XY DSD showed better psychosocial adjustment than older ones. Younger women showed lower age at diagnosis communication. Psychological support was more often proposed at the time of diagnosis communication to younger individuals, and they undertook it more frequently than older ones.

CONCLUSIONS

Italian people living with 46,XY DSD were well adapted and successful; they reported a good QoL but showed higher degree of psychological distress than the comparison group. Lower psychological distress in younger women could indicate some positive effects of changes in management.

DSDs: genetics, underlying pathologies and psychosexual differentiation

Mammalian sex determination is the unique process whereby a single organ, the bipotential gonad, undergoes a developmental switch that promotes its differentiation into either a testis or an ovary. Disruptions of this complex genetic process during human development can manifest as disorders of sex development (DSDs). Sex development can be divided into two distinct processes: sex determination, in which the bipotential gonads form either testes or ovaries, and sex differentiation, in which the fully formed testes or ovaries secrete local and hormonal factors to drive differentiation of internal and external genitals, as well as extragonadal tissues such as the brain. DSDs can arise from a number of genetic lesions, which manifest as a spectrum of gonadal (gonadal dysgenesis to ovotestis) and genital (mild hypospadias or clitoromegaly to ambiguous genitalia) phenotypes. The physical attributes and medical implications associated with DSDs confront families of affected newborns with decisions, such as gender of rearing or genital surgery, and additional concerns, such as uncertainty over the child's psychosexual development and personal wishes later in life. In this Review, we discuss the underlying genetics of human sex determination and focus on emerging data, genetic classification of DSDs and other considerations that surround gender development and identity in individuals with DSDs.

Unbiased identification of patients with disorders of sex development

Disorders of sex development (DSD) represent a collection of rare diseases that generate substantial controversy regarding best practices for diagnosis and treatment. A significant barrier preventing a better understanding of how patients with these conditions should be evaluated and treated, especially from a psychological standpoint, is the lack of systematic and standardized approaches to identify cases for study inclusion. Common approaches include "hand-picked" subjects already known to the practice, which could introduce bias. We implemented an informatics-based approach to identify patients with DSD from electronic health records (EHRs) at three large, academic children's hospitals. The informatics approach involved comprehensively searching EHRs at each hospital using a combination of structured billing codes as an initial filtering strategy followed by keywords applied to the free text clinical documentation. The informatics approach was implemented to replicate the functionality of an EHR search engine (EMERSE) available at one of the hospitals. At the two hospitals that did not have EMERSE, we compared case ascertainment using the informatics method to traditional approaches employed for identifying subjects. Potential cases identified using all approaches were manually reviewed by experts in DSD to verify eligibility criteria. At the two institutions where both the informatics and traditional approaches were applied, the informatics approach identified substantially higher numbers of potential study subjects. The traditional approaches yielded 14 and 28 patients with DSD, respectively; the informatics approach yielded 226 and 77 patients, respectively. The informatics approach missed only a few cases that the traditional approaches identified, largely because those cases were known to the study team, but patient data were not in the particular children's hospital EHR. The use of informatics approaches to search electronic documentation can result in substantially larger numbers of subjects identified for studies of rare diseases such as DSD, and these approaches can be applied across hospitals.

Management of disorders of sex development

The medical term disorders of sex development (DSDs) is used to describe individuals with an atypical composition of chromosomal, gonadal and phenotypic sex, which leads to differences in the development of the urogenital tract and reproductive system. A variety of genetic factors have been identified that affect sex development during gonadal differentiation or in specific disorders associated with altered androgen biosynthesis or action. The diagnosis of DSDs in individuals and the subsequent management of patients and their families requires a targeted and structured approach, involving a multidisciplinary team with effective communication between the disciplines. This approach includes distinct clinical, imaging, laboratory and genetic evaluations of patients with DSDs. Although treatment of patients with DSDs can include endocrine and surgical options, many patients have concerns that arise from past incorrect treatments that were founded on the traditional binary concept of the sexes. To dispel these concerns, it is necessary to create centres of expertise for DSDs that include physicians, surgeons, psychologists and specialists in diagnostic procedures to manage patients and their families. Additionally, the inclusion of trained peer support in the multidisciplinary DSD team seems to be integral to the supportive management of patients with DSDs. Most importantly, dealing with DSDs requires acceptance of the fact that deviation from the traditional definitions of gender is not necessarily pathologic.

Utilization of health care services and satisfaction with care in adults affected by disorders of sex development (DSD)

BACKGROUND

Disorders of sex development (DSD) are a heterogeneous group of rare genetic disorders of sex determination or differentiation. Evidence-based guidelines concerning gender assignment and surgical and hormonal treatment are limited for many DSD entities, and health care is highly fragmented across various sub-specialties and settings. A lack of informed consent, secrecy about the condition, shame, and impaired sexual and psychosocial functioning may affect satisfaction with care.

OBJECTIVES

The main goal of this study was to describe satisfaction with care in individuals with DSD and to identify factors associated with low satisfaction with care. METHODS/MAIN MEASURES: Using both biological (chromosomes) and social categories (sex of rearing), we classified participants according to the nomenclature of the European Society for Pediatric Endocrinology/Lawson Wilkins Pediatric Endocrine Society (ESPE/LWPES) consensus statement. We used standardized measures to assess satisfaction with care (CSQ-8), health-related quality of life (SF-36), psychological symptoms (BSI), and gender identity (FGI), in addition to self-constructed questionnaires probing experiences with health care and access to self-help groups.

PARTICIPANTS

A total of 110 adults were recruited between January 2005 and December 2007 in four study centers in Germany, Austria, and German-speaking Switzerland.

RESULTS

Reports of half the participants scored below the cut-off indicating low quality of care. Women with XX DSD conditions and virilization (i.e., congenital adrenal hyperplasia) reported the highest scores for satisfaction with care, and women with XY DSD conditions and complete lack of androgen effects reported the lowest scores. Satisfaction with care was positively associated with indicators of psychological well-being.

CONCLUSIONS

Satisfaction with care is lowest among participants with the rarest conditions, highlighting the lack of evidence-based recommendations and the lack of coordination of care. Associations of satisfaction and well-being indicate the need to ensure access to mental health services.

Health-related quality of life in children with disorders of sex development (DSD)

Disorders of sex development (DSD) are rare genetic conditions resulting in atypical development of the sex organs. While some evidence is available on psychosexual outcomes, much less is known about the quality of life in this population, especially in children. Health-related quality of life (HRQOL) is a widely accepted endpoint for assessment and evaluation of interventions and medical care. Within the German DSD Network study, 86 children aged 8-12 years with several subtypes of DSD were recruited from Germany, Austria and Switzerland. Demographic, medical and psychosocial variables were collected through interviews of the attending physicians, the children and the parents. HRQOL was the primary outcome. It was assessed by the KINDL-R Questionnaire [2001]. Psychosexual determinants included gender identity/gender dysphoria, gender role behaviour, the child's knowledge about the condition and number/timing of genital surgery. A significant reduction of HRQOL was reported in children's self-report (p < 0.001), in particular in the area of self-esteem (p < 0.001), physical well-being (p < 0.01) and school functioning (p < 0.05). Girls with congenital adrenal hyperplasia who experienced gender dysphoria reported lower HRQOL scores compared to the study group at large. Atypical gender role behaviour was not associated with HRQOL.

CONCLUSION

Psychosocial support of children with DSD and their families appears to be necessary in at least some cases and must be accessible for all patients.

Long-term evaluation of patients undergoing genitoplasty due to disorders of sex development: results from a 14-year follow-up

PURPOSE

To summarize the experience in treating patients with genitoplasty due to disorders of sex development in China.

METHODS

The operative procedures, gender of rearing, surgical outcome, and psychosocial and family adjustments of 262 patients were reviewed retrospectively.

RESULTS

At initial diagnosis, the mean age was 14.3 ± 2.8 years (range: 2-38 years). There were 96 children, 133 adolescents, and 33 adults. Follow-up was done every 6 months. Patients with female sex assignment had no urinary incontinence or voiding difficulty. Five patients underwent the second surgery (3%); vaginal dilation was performed in 35 patients with postoperative vaginal stenosis; 12 patients (7.4%) were unsatisfactory with the outcome. For patients with male sex assignment, the median length of penis was 2.2 cm in prepubertal patients, 4.2 cm in pubertal patients, and 5.0 cm in adults; 39 patients developed postvoid dribbling (39%); 21 patients underwent a second surgery (21%); urethral dilation was done in 28 patients (28%) due to urethral stricture; 38 patients were unsatisfactory with the outcome (38%). In addition, 136 patients (83%) with female sex assignment and 54 (54%) with male sex assignment had favorable psychosocial adjustment.

CONCLUSIONS

Patients with male sex assignment have more surgical complications and difficulties in psychosocial adjustment as compared to those with female sex assignment.

Translational genetics for diagnosis of human disorders of sex development

Disorders of sex development (DSDs) are congenital conditions with discrepancies between the chromosomal, gonadal, and phenotypic sex of the individual. Such disorders have historically been difficult to diagnose and cause great stress to patients and their families. Genetic analysis of human samples has been instrumental in elucidating the molecules and pathways involved in the development of the bipotential gonad into a functioning testis or ovary. However, many DSD patients still do not receive a genetic diagnosis. New genetic and genomic technologies are expanding our knowledge of the underlying mechanism of DSDs and opening new avenues for clinical diagnosis. We review the genetic technologies that have elucidated the genes that are well established in sex determination in humans, discuss findings from more recent genomic technologies, and propose a new paradigm for clinical diagnosis of DSDs.

Targeted massively parallel sequencing provides comprehensive genetic diagnosis for patients with disorders of sex development

Disorders of sex development (DSD) are rare disorders in which there is discordance between chromosomal, gonadal, and phenotypic sex. Only a minority of patients clinically diagnosed with DSD obtains a molecular diagnosis, leaving a large gap in our understanding of the prevalence, management, and outcomes in affected patients. We created a novel DSD-genetic diagnostic tool, in which sex development genes are captured using RNA probes and undergo massively parallel sequencing. In the pilot group of 14 patients, we determined sex chromosome dosage, copy number variation, and gene mutations. In the patients with a known genetic diagnosis (obtained either on a clinical or research basis), this test identified the molecular cause in 100% (7/7) of patients. In patients in whom no molecular diagnosis had been made, this tool identified a genetic diagnosis in two of seven patients. Targeted sequencing of genes representing a specific spectrum of disorders can result in a higher rate of genetic diagnoses than current diagnostic approaches. Our DSD diagnostic tool provides for first time, in a single blood test, a comprehensive genetic diagnosis in patients presenting with a wide range of urogenital anomalies.

Psychosexual development in adolescents and adults with disorders of sex development--results from the German Clinical Evaluation Study

INTRODUCTION

Both biological and psychosocial factors influence psychosexual development. High levels of pre- and postnatal androgens lead to more male-typical behavior. So far, the influence of androgens on gender identity and sexual orientation is unclear. Disorders of sex development (DSDs) are heterogeneous genetic conditions with different levels of prenatal androgens resulting in variations of genital development. Through DSD, the role of the different factors, especially androgen exposure, on psychosexual development can be evaluated.

AIM

The purpose of the study was to assess psychosexual development in adolescents and adults with different forms of DSD.

METHODS

For the examination of psychosexual development of 66 adolescents and 110 adults with DSD, the authors used the Utrecht Gender Dysphoria Scale for adolescents, the Questionnaire of Gender Identity for adults, and a condition-specific DSD study questionnaire. Individuals were analyzed in four subgroups reflecting the karyotype, absence/presence of androgen effects, and gender of rearing.

MAIN OUTCOME MEASURES

Main outcome measures used were gender identity, friendships, love and sexual relationships, and sexual orientation in adolescents and adults with DSD.

RESULTS

Individuals with DSD did not show increased gender dysphoria. However, partnership and sexuality were identified to be difficult areas of life. Both adolescents and adults with DSD reported fewer experiences regarding love or sexual relationships compared with unaffected individuals. Especially men with DSD and undervirilization and women with DSD and androgen effects less often had a love relationship. Adult women with DSD and androgen effects more frequently engaged in love and sexual relationships with individuals of the same gender compared with women without DSD.

CONCLUSION

Individuals with DSD experience atypical hormonal influences (higher levels of androgens in girls/women and lower levels in androgens in boys/men); however, they did not show increased gender dysphoria in this study. However, partnership and sexual relationships are difficult areas of life for adolescents and adults with DSD. We recommend that individuals with DSD should get support from a multiprofessional team with competency in assessing and counseling issues regarding relationships and sexuality. Contact to other individuals with DSD can be helpful for nonprofessional support and exchange of experiences.

Psychological adjustment and sexual development of adolescents with disorders of sex development

PURPOSE

Disorders of sex development (DSD) are a heterogeneous group of congenital conditions characterized by an atypical development of chromosomal, gonadal, or anatomical sex. Particularly at the time of expected puberty, adolescents with DSD may become aware of being different from peers. This study explores the effect of DSD on psychosocial well-being and sexual development.

METHODS

We interviewed 60 adolescents aged 13-16 years with a DSD. To measure health-related quality of life, mental health, and body image, we used standardized instruments and additional questions related to sexuality and coping with DSD. Reference and control data were available from the German Health Survey for Children and Adolescents (Kiggs) and from a secondary school survey.

RESULTS

The general psychological well-being of adolescents with DSD was not impaired. However, outcomes related to adolescent developmental tasks like sexual activities demonstrated impaired participation, especially girls with DSD reported fewer sexual activities than female controls. Adolescents who needed hormonal treatment to induce puberty reported impaired well-being in nearly all outcomes in contrast to those who entered puberty spontaneously.

CONCLUSIONS

Interdisciplinary health care teams should focus on the pressure of conformity and openly discuss it with the adolescent in context of treatment decisions. Furthermore, special counseling concerning sexuality and coping with the condition in daily life is needed.

Long-term psychosocial adjustments, satisfaction related to gender and the family equations in disorders of sexual differentiation with male sex assignment

PURPOSE

The varied management and counseling in disorders of sexual differentiation (DSD) depends a lot on the socioeconomic structure. A follow-up study was designed to evaluate the outcome in terms of patient satisfaction with strong socio-cultural issues.

METHOD

Of the 1,134 DSD patients being followed up in pediatric intersex clinic, 60 adolescents and adults assigned male sex in childhood were called for follow-up. They were interviewed for psychosocial and family adjustments including level of acceptance of gender, social relationships and future expectations.

RESULTS

The ages ranged from 15 to 25 years (mean, 19.3 ± 3.7 years). The disorders were male pseudo hermaphrodite (MPH)-43, mixed gonadal dysgenesis (MGD)-3, true hermaphrodite (TH)-7 and congenital adrenal hyperplasia (CAH)-7. Of all patients, 85% (51/60) felt satisfied with their gender assignment; 76.9% (46/60) did not feel comfortable with the opposite sex. Penile erections; ejaculation and masculine voice were present in 53, 44 and 47 patients. Facial hair was normal; sparse and absent in 16, 26 and 18 patients, respectively. Stretched penile length was 2.5-9 cm (median, 5.5 cm) and 16/60 patients were satisfied with their penile length; 28 patients required redo surgeries for scrotum diverticulum (1), proximal penile diverticulum (1), stricture urethra (2), hair in the urethra (3), vaginal pouch dilatation (1), orchiopexy (2), residual chordee correction (3), distal urethroplasty (4), urethral fistula repair (21), mastectomy (6) and testicular prosthesis (4). Family support was available to all 85% (51/60) of the patients who had good family relationships. However, only 15% (9/60) felt that they fitted into society. Peer relationships were considered 'good' by 43/60 and poor by 17/60. Two patients had got married and 44.8% (26/58) patients would consider marriage in future. Most patients (42/60) were worried about the smaller size of the phallus and lack of adequate semen, leading to apprehension before marriage. As much as 15 patients had jobs, 15 attended school, 3 attended colleges and 17 illiterate patients were dependent on their families.

CONCLUSIONS

Despite moral, social and economic support provided by the parents, children with DSD continue to have apprehensions in social adjustments.

Disorders of sex development and Diamond-Blackfan anemia: is there an association?

Diamond-Blackfan anemia (DBA) is a rare disorder characterized by congenital pure red cell aplasia. Mutations in ribosomal protein S19 (RPS19) have been identified in 25% of DBA patients. More recently, mutations in other ribosomal protein genes, namely RPS7, RPS15, RPS24, RPS17, RPS27A, RPL35a, RPL36, RPL11, and RPL5, have also been found in patients with DBA. Approximately 30-40% of affected patients have various associated physical anomalies, mostly craniofacial and at the extremities, but also cardiac or urogenital malformations. Anomalies of the urogenital tract in DBA patients comprise changes in the kidney (dysplasia, agenesis, duplication, horseshoe kidney) and genitalia (hypospadias). To date, disorders of sex development (DSD) have only been described once in association with DBA. We report here four DBA patients who exhibited DSD.

Psychosexual development in children with disorder of sex development (DSD)--results from the German Clinical Evaluation Study

Psychosexual development is influenced by biological and psychosocial factors. Human beings show a great variability in psychosexual development both between and within gender-groups. However, there are relatively stable gender-related behaviors and self-perceptions, in which males and females differ distinctly. There is strong evidence that high concentrations of androgens lead to more male-typical behavior and that this also influences gender identity. Disorders of sex development (DSD) provide the opportunity to analyze the role of different factors on psychosexual development. We examined 166 children age 4 to 12 with DSD using instruments concerning gender role behavior, gender identity, and friendship. Results underline the hypothesis, that androgens play a decisive role in the masculinization of gender role behavior in children. There are also some relations between the experience of gender change and psychosexual outcomes which have to be discussed. Nevertheless, results indicated a high congruence between the children's gender identity and gender of rearing.

46,XY DSD with Female or Ambiguous External Genitalia at Birth due to Androgen Insensitivity Syndrome, 5alpha-Reductase-2 Deficiency, or 17beta-Hydroxysteroid Dehydrogenase Deficiency: A Review of Quality of Life Outcomes

Disorders of sex development refer to a collection of congenital conditions in which atypical development of chromosomal, gonadal, or anatomic sex occurs. Studies of 46,XY DSD have focused largely on gender identity, gender role, and sexual orientation. Few studies have focused on other domains, such as physical and mental health, that may contribute to a person's quality of life. The current review focuses on information published since 1955 pertaining to psychological well-being, cognition, general health, fertility, and sexual function in people affected by androgen insensitivity syndromes, 5-α reductase-2 deficiency, or 17β-hydroxysteroid dehydrogenase-3 deficiency—reared male or female. The complete form of androgen insensitivity syndrome has been the focus of the largest number of investigations in domains other than gender. Despite this, all of the conditions included in the current review are under-studied. Realms identified for further study include psychological well-being, cognitive abilities, general health, fertility, and sexual function. Such investigations would not only improve the quality of life for those affected by DSD but may also provide information for improving physical and mental health in the general population.
