Gender Identity and Gender Role in DSD Patients Raised as Females: A Preliminary Outcome Study

The role of the pediatrician in the management of the child and adolescent with gender dysphoria

Gender dysphoria is a clinical condition characterized by significant distress due to the discordance between biological sex and gender identity. Currently, gender dysphoria is also found more frequently in children and adolescents, thanks to greater social sensibleness and new therapeutic possibilities. In fact, it is estimated that the prevalence of gender dysphoria in pediatric age is between 0.5% and 2% based on the statistics of the various countries. Therefore, the pediatrician cannot fail to update himself on these issues and above all should be the reference figure in the management of these patients. Even if the patient must be directed to a referral center and be followed up by a multidisciplinary team, the treating pediatrician will care to coordinate the clinical and therapeutic framework. The aim of the present report is therefore to integrate literature data with our clinical experience to propose a new clinical approach in which the pediatrician should be the reference in the care of these patients, directing them towards the best therapeutic approach and staying in contact with the specialists of the referral center.

Gender identity disorder (GID) in adolescents and adults with differences of sex development (DSD): A systematic review and meta-analysis

Gender assignment in infants born with a difference in sexual development (DSD) remains one of the many difficult decisions faced by the multi-disciplinary treatment team as some of these children develop gender identity disorder (GID) when they become adults. In this systematic review and meta-analysis we have analyzed the prevalence of GID in adolescent and adults with DSD. The secondary outcome of this review is to help physicians in appropriate sex assignment of DSD children so that development of GID in later life can be reduced.

METHODS

Pubmed/Index medicus were searched for "intersex" [All fields] OR "disorders of sexual differentiation AND "gender identity disorder OR gender dysphoria" [MeSH] for articles published between 2005 and 2020. Typical diagnoses included were congenital adrenal hyperplasia (CAH); complete androgen insensitivity syndrome (CAIS); partial androgen insensitivity syndrome (PAIS); 5 alpha reductase deficiency (5ARD); 17-hydroxysteroid dehydrogenase deficiency (17HSD); mixed gonadal dysgenesis (MGD) and complete gonadal dysgenesis (CGD). GID or gender dysphoria (a strong feeling of dissatisfaction about oneself as male or female) prevalence in DSD patients older than 12 years of age was extracted. Within each condition, GID percentage was compared between female and male rearing.

RESULTS

The I2statistics for prevalence of GID in DSD showed high heterogeneity with I2 of 93% (95% C.I 90-95%) among the 20 articles included. The overall prevalence of GID among those with DSD was 15% (95% C.I 13-17%). CAH reared females had 4% GID while CAH reared males had significantly higher GID at 15% (p = 0.0056). All CAIS patients were raised as females and the prevalence of GID was 1.7%. GID prevalence was 12% in PAIS raised as females while 25% in those raised as males with no significant difference (p = 0.134). GID was significantly high in 5ARD (53%) and 17HSD (53%) reared as females with half of them virilizing at puberty forcing a gender change. Among sex chromosome DSD 22% of those reared as females had GID while none in those raised as male with no significant difference.

CONCLUSIONS

GID is low in women with CAH, CAIS and CGD favoring female sex of rearing in these conditions. GID is high in women with 5ARD/17HSD favoring male sex of rearing in these conditions. GID is variable in PAIS or MGD and no recommendations on sex of rearing could be made in these conditions. Each DSD patient is unique and they warrant multi-disciplinary care and long term psycho sexual support.

Brain Sex Differences Related to Gender Identity Development: Genes or Hormones?

The complex process of sexual differentiation is known to be influenced by biological and environmental determinants. The present review has the aim of summarizing the most relevant studies on the biological basis of sexual development, and in particular, it focuses on the impact of sex hormones and genetic background on the development of sexual differentiation and gender identity. The authors conducted a search of published studies on Medline (from January 1948 to December 2019). The evidence suggests that the sexual dimorphic brain could be the anatomical substrate of psychosexual development, on which gonadal hormones may have a shaping role during prenatal and pubertal periods. Additionally, according to several heritability studies, genetic components may have a role, but a promising candidate gene has not been identified. Even though growing evidence underlines the primary role of biological factors on psychosexual development, further studies are necessary to better explain their complex interactions.

The molecular mechanisms of sexual orientation and gender identity

Differences between males and females are widely represented in nature. There are gender differences in phenotypes, personality traits, behaviors and interests, cognitive performance, and proneness to specific diseases. The most marked difference in humans is represented by sexual orientation and core gender identity, the origins of which are still controversial and far from being understood. Debates continue on whether sexual behavior and gender identity are a result of biological (nature) or cultural (nurture) factors, with biology possibly playing a major role. The main goal of this review is to summarize the studies available to date on the biological factors involved in the development of both sexual orientation and gender identity. A systematic search of published evidence was performed using Medline (from January 1948 to June 2017). Review of the relevant literature was based on authors' expertise. Indeed, different studies have documented the possible role and interaction of neuroanatomic, hormonal and genetic factors. The sexual dimorphic brain is considered the anatomical substrate of psychosexual development, on which genes and gonadal hormones may have a shaping effect. In particular, growing evidence shows that prenatal and pubertal sex hormones permanently affect human behavior. In addition, heritability studies have demonstrated a role of genetic components. However, a convincing candidate gene has not been identified. Future studies (e.i. genome wide studies) are needed to better clarify the complex interaction between genes, anatomy and hormonal influences on psychosexual development.

Ambiguous genitalia-A social dilemma in Bangladesh: A case report

INTRODUCTION

Ambiguous Genitalia is a form of birth defect in which sex of the newborn cannot be readily distinguishable because of atypical appearance of the external genitalia.

CASE REPORT-CLINICAL FINDINGS

The patient, an 8 months old baby, was identified as a female baby since birth; but, some senior members of their neighborhood raised confusion regarding sex differentiation of the child. On examination, there was enlarged clitoris or micropenis, bifid scrotum or labioscrotal fold, and separate presence of urethral and vaginal orifices. Right testis was found in the middle of right inguinal canal and left testis was found near the deep inguinal ring.

CASE REPORT-DIAGNOSIS, THERAPEUTIC INTERVENTION AND OUTCOME

The ultrasonogram showed a rudimentary uterus measuring 26.7×7.27mm with no ovary and the right testis was found in the mid inguinal canal while the left testis was in the deep inguinal ring. Diagnostic endoscopic procedure showed normal appearing testes in deep inguinal ring, about 2cm vaginal remnant with normal urethra and bladder. Hormonal study revealed low serum testosterone with normal DHT and high oestradiol while the karyotyping revealed 46XY. After 3 months of hormonal treatment, multiple surgical interventions were taken to correctly determine the sex of the child. Later on the patient was discharged with follow up advices.

CONCLUSION

'Ambiguous genitalia' is considered as a taboo in Bangladesh; hence, the social awareness regarding this curable disorder is a timely need in Bangladesh.

Gender of rearing and psychosocial aspect in 46 XX congenital adrenal hyperplasia

BACKGROUND

In congenital adrenal hyperplasia (CAH) with ambiguous genitalia, assigning gender of rearing can be complex, especially If genitalia is highly virilized. Apart from karyotype, prenatal androgen exposure, patient's gender orientation, sociocultural, and parental influences play a role. The aim of this study was to assess gender dysphoria and psychosocial issues in patients of CAH raised as males and females.

MATERIALS AND METHODS

This is a cross-sectional study that includes patients (old and new) with CAH who were treated by us in the last 6 months. A semi-structured interview proforma was used to elicit history and psychosocial background of the patients. The clinical and biochemical details were noted. For psychological analysis, patients were screened for gender dysphoria using Parent Report Gender Identity Questionnaire for children <12 years and Gender Identity/Gender Dysphoria Questionnaire for Adolescents and Adults.

RESULTS

We analyzed 22 46 XX CAH patients among which, 3 were reared as males and 19 as females. Among the 19 patients reared as females, 17 patients showed no gender dysphoria. Two patients revealed gender dysphoria as indicated by their marginally low scores on the gender dysphoria assessment. However, in view of current literature and the age groups of the patients, behavior of the 6-year-old patient can be best understood as being tomboyish. Gender dysphoria in the 22-year-old can be explained by the dominance of psychosocial factors and not hormones alone. Among the three patients reared as males, two prepubertal were satisfied with their male gender identity. The third patient, aged 32 years, had gender dysphoria when reared as a male that resolved when gender was reassigned as female and feminizing surgery was done.

CONCLUSION

Gender assignment in 46 XX CAH is guided by factors such as degree of virilization of genitalia, gender orientation, patient involvement, sociocultural, and parental influences.

Gender identity, gender assignment and reassignment in individuals with disorders of sex development: a major of dilemma

INTRODUCTION

Disorders of Sex Development (DSD) are a wide range of congenital conditions characterized by an incongruence of components involved in sexual differentiation, including gender psychosexual development. The management of such disorders is complex, and one of the most crucial decision is represented by gender assignment. In fact, the primary goal in DSD is to have a gender assignment consistent with the underlying gender identity in order to prevent the distress related to a forthcoming Gender Dysphoria. Historically, gender assignment was based essentially on surgical outcomes, assuming the neutrality of gender identity at birth. This policy has been challenged in the past decade refocusing on the importance of prenatal and postnatal hormonal and genetic influences on psychosexual development.

AIMS

(1) to update the main psychological and medical issues that surround DSD, in particular regarding gender identity and gender assignment; (2) to report specific clinical recommendations according to the different diagnosis.

METHODS

A systematic search of published evidence was performed using Medline (from 1972 to March 2016). Review of the relevant literature and recommendations was based on authors' expertise.

RESULTS

A review of gender identity and assignment in DSD is provided as well as clinical recommendations for the management of individuals with DSD.

CONCLUSIONS

Given the complexity of this management, DSD individuals and their families need to be supported by a specialized multidisciplinary team, which has been universally recognized as the best practice for intersexual conditions. In case of juvenile GD in DSD, the prescription of gonadotropin-releasing hormone analogues, following the World Professional Association for Transgender Health and the Endocrine Society guidelines, should be considered. It should always be taken into account that every DSD person is unique and has to be treated with individualized care. In this perspective, international registries are crucial to improve the understanding of these challenging conditions and clinical practice, in providing a better prediction of gender identity.
