Abstract Introduction: Differences of Sex Development (DSDs) encompass variations in formation of internal or external sex characteristics. Historically, sex assignment in children with DSDs depended on phenotype, and gender was thought to be malleable. Attention in DSD has recently shifted toward reducing gender dysphoria and preserving fertility potential. Our multidisciplinary DSD clinic was formed in 2008 with these goals and includes specialists from Endocrinology, Gynecology, Urology, Psychology, Social Work, Genetics, and Chaplaincy. Subjects: A chart review was done on all patients seen in our DSD clinic between April 2008 and June 2019 to determine rates of sex reassignment and gender dysphoria. Two hundred patients were seen: 23 were found to not have DSDs; 61 were 46,XX; 66 were 46,XY; 31 had a sex chromosome DSD; 5 had gonadal dysgenesis without known chromosome mosaicism; and 14 had syndromic genital atypia. Mean age of follow-up is 8.77 years. Results: Only 2 patients underwent sex reassignment at our institution. One was assigned male at birth, but was found to be 46,XX with 21-hydroxylase deficiency and was reassigned female at 1 month of age. The second was assigned male at birth and was found to be 46,XY with an NR5A1 variant. Sex was reassigned female at two months of age. Two additional patients had a sex reassignment outside our institution. One was born abroad and assigned male at birth. The patient was found to be 46,XY with an NR5A1 variant, and was reassigned female. The second patient was assigned male at birth, but was found to be 46,XX with P450 oxidoreductase deficiency. The parents changed the sex of rearing to female at 19 months of age. To date, none has signs of gender dysphoria. A total of three patients experienced gender dysphoria and underwent transition. The first had genital ambiguity with sex chromosome mosaicism in the gonads and was assigned female at birth. We held care conferences with the family and discussed the possibility of gender dysphoria. At age 3, the patient declared that he was male, and parents socially transitioned him at that time. Two were assigned female after receiving the diagnosis of 46,XX 21-hydroxylase deficiency. Both declared male gender identity later, one at 12.5 years of age, and one at 20.5 years of age. Conclusion: Whereas our patient population is still relatively young, it is reassuring that the overall rate of gender dysphoria is low. The rate in patients with CAH is similar to previous reports in the literature. Careful attention to sex assignment in early childhood may reduce the rates of gender dysphoria in children with DSDs.

21 Hydroxylase Deficiency

Disorders of sex development (DSD), formerly termed “intersex” conditions, arise from numerous causes. CAH secondary to 21-hydroxylase deficiency is the most common cause of DSD. Sex chromosome disorders, including sex chromosome mosaicism, are the second most common cause of DSD. We discuss a medically complex neonate with DSD presenting with ambiguous genitalia. Hormone levels suggested 21-hydroxylase deficiency. Molecular analysis revealed compound heterozygous mutations in the 21-hydroxylase gene (CYP21A2), confirming the diagnosis of CAH. Chromosome analysis revealed sex chromosome mosaicism with three cell lines: 45,X[8]/45,X,tas(Y;16)(p11.32;p13.3)[8]/45,X,t(Y;8)(p11.32;p23.3)[4] with the Y chromosome in telomere association with chromosomes 8p and 16p in different cell lines, a “jumping translocation.” Histologically, the right gonad had irregular, distended seminiferous tubules with hyperplastic germ cells contiguous with ovarian stroma and primordial follicles. The left gonad had scant ovarian stroma and embryonic remnants. Chromosome analyses showed mosaicism in both gonads: 45,X[17]/45,X,tas(Y;8)(p11.32;p23.3)[3]. This is the first case of coexisting CAH and 45,X/46,XY mosaicism reported in the English literature and the third case of a constitutional chromosome Y “jumping translocation.” Our report documents the medical and genetic complexity of children such as this one with ambiguous genitalia and discusses the need for a multidisciplinary team approach.

Abstract Introduction: Congenital Adrenal Hyperplasia (CAH) is defined as a group of autosomal recessive disorders characterized by a deficiency of the enzyme required to synthesize cortisol by the adrenal cortex. Defects in the 21-hydroxylase enzyme make up 90% of CAH. These defects impaired cortisol synthesis leading to an ACTH increase resulting in androgen excess in both salt-wasting (SW) or simple virilizing (SV) forms. As androgens play a role in the human psychosexual development favoring male psychosexuality, this study was designed to evaluate the impact of androgen exposure on the psychosexuality of individuals with CAH due 21-hydroxylase deficiency. Methods: This retrospective cohort includes 46,XX individuals (115 female-assigned; 8 male-assigned) with a molecular diagnosis of CAH due to CYP21A2 pathogenic variants in homozygous or compounds heterozygous state. External genitalia virilization was scored using Prader scale. Phenotype, time at diagnosis, sex assignment, and gender change were assessed. The gender role at childhood was assessed through the playmates and toys profile at childhood. Gender identity was assessed by a projective psychological test (HTP). Sexual orientation was assessed by self-report sexual identity. Compliance of glucocorticoid replacement was assessed by adequate testosterone and androstenedione serum levels for age. Results: CAH was diagnosed at the neonatal time in 73% (n=78). Fifth-nine (51%) had the SW form and 49% (n=56) had the SV form. While all cases of SW were diagnosed at the neonatal time (0.12 ± 0.14 months), the mean age at diagnosis among SV was 6.03 ± 8.45 years (p=<.001). The median of Prader score was 3 in both forms. Male sex assignment was associated with more virilized external genitalia (p=.002). Gender change occurred in 6 cases (female to male), all with SV form. The prader score was higher among those who changed gender (p=.01). All of those who changed their gender had poor treatment compliance. A total of 13% (n=15) of all groups defined themselves as homosexual. There was a strong association between male toys and preference for male playmates in childhood with homosexuality and male gender identity in adulthood with both gender change from female to male and homosexuality. Conclusion: Prenatal androgen exposure favors male psychosexuality in 46,XX CAH individuals as observed by the association between highest Prader scores and all assessed psychosexual outcomes. This influence is also substantiated by post-natal androgen exposure as observed by compliance issues and late diagnosis among those who changed from female to male gender.

Abstract Background Antley-Bixler syndrome (ABS) caused by P450 oxidoreductase deficiency (PORD) is a congenital adrenal hyperplasia with skeletal malformations and disordered sex development in both sexes. There have been no reports of ABS caused by PORD in Chinese children. Methods We described the clinical and genetic characteristics of eight Chinese children with ABS caused by PORD and compared them with those of subjects in previous studies. Results Eight patients, aged 6 months–17.8 years, showed strikingly similar craniofacial malformations. We first described four unreported features: lower eyelid fat pads (4/8), prominent lower eyelid-zygoma transverse line (4/8), underdeveloped or absent antihelix (5/8) and single earlobe crease (5/8). Five 46, XY patients presented various degrees of undervirilization, while three 46, XX cases showed masculinization. Basal endocrine measurements revealed the following consistent results: normal cortisol; elevated adrenocorticotropic hormone, progesterone, pregnenolone, 17-hydroxypropgesterone, and corticosterone; and decreased or normal testosterone/oestradiol. We identified three previously reported variants and four novel variants (c.51719_51710delGGCCCCTGTGinsC, p.D210G, p.Y248X and p.R554X) of POR. The most prevalent variant was p.R457H (8/16). The hydrocortisone dosages of patients differed because of variable degrees of adrenal insufficiency. Conclusions We described novel phenotypes and genotypes of ABS caused by PORD. The variant p.R457H was the most prevalent in this cohort. All subjects had combined characteristics of 17-hydroxylase and 21-hydroxylase deficiency. Steroid replacement therapy for patients with PORD requires individually tailored dosing.

Objective. To evaluate diagnosis, age of referral, karyotype, and sex of rearing of cases with disorders of sex development (DSD) with ambiguous genitalia.Methods. Retrospective study during 23 years at outpatient clinic of a referral center.Results. There were 408 cases; 250 (61.3%) were 46,XY and 124 (30.4%) 46,XX and 34 (8.3%) had sex chromosomes abnormalities. 189 (46.3%) had 46,XY testicular DSD, 105 (25.7%) 46,XX ovarian DSD, 95 (23.3%) disorders of gonadal development (DGD), and 19 (4.7%) complex malformations. The main etiology of 46,XX ovarian DSD was salt-wasting 21-hydroxylase deficiency. In 46,XX and 46,XY groups, other malformations were observed. In the DGD group, 46,XY partial gonadal dysgenesis, mixed gonadal dysgenesis, and ovotesticular DSD were more frequent. Low birth weight was observed in 42 cases of idiopathic 46,XY testicular DSD. The average age at diagnosis was 31.7 months. The final sex of rearing was male in 238 cases and female in 170. Only 6.6% (27 cases) needed sex reassignment.Conclusions. In this large DSD sample with ambiguous genitalia, the 46,XY karyotype was the most frequent; in turn, congenital adrenal hyperplasia was the most frequent etiology. Malformations associated with DSD were common in all groups and low birth weight was associated with idiopathic 46,XY testicular DSD.

21 Hydroxylase Deficiency

Congenital Adrenal Hyperplasia (CAH) is considered to be the most common cause of genital ambiguity in children. According to World’s literature, 90-95% of this disease is caused by 21-hydroxylase deficiency that impairs the synthesis of cortisol and aldosterone. The consequent excess in androgen production leads to virilization in the affected females. This study was aimed to find the number of cases with CAH (21-hydroxylase deficiency) in the children presented with disorders of sexual differentiation. For this purpose, 100 patients presented to The Children’s hospital for gender assessment were taken and their 17- OH progesterone levels were measured to confirm 21-hydroxylase deficiency, and chromosomal analysis was done to confirm chromosomal sex. Results indicated that out of 100 patients 49 were suffering from CAH. 63.2% of CAH patients were initially presented as males. Out of these, 44.8% were reassigned female gender on chromosomal analysis. So, it is concluded that the majority of patients presented with genital ambiguity in the tertiary care health facility have the ambiguity due to congenital adrenal hyperplasia.

21 Hydroxylase Deficiency

11β-hydroxylase deficiency is a rare autosomal recessive disorder due to impaired steroidogenesis in the adrenal cortex caused by pathogenic mutations in the CYP11B1 gene. The main clinical manifestations are determined by a deficiency of cortisol, ACTH hyperproduction, excessive androgens secretion and the accumulation of 11-deoxycorticosterone, which leads to the development of arterial hypertension. In the diagnostic search, it is important to take into account the ethnicity of the patient, since the frequency of the disease and the prevalence of mutations differ between ethnic groups. The article presents a clinical case of 11β-hydroxylase deficiency as the result of compound heterozygous mutations in the CYP11B1 gene in a patient of Turkic origin. This case shows the clinical manifestations and the development of complications of 11β-hydroxylase deficiency, the stages of differential diagnosis of patients with 21-hydroxylase deficiency.

The Impact

Variables that impact gender development in humans are difficult to evaluate. This difficulty exists because it is not usually possible to tease apart biological influences on gender from social variables. People with disorders of sex development, or DSD, provide important opportunities to study gender within individuals for whom biologic components of sex can be discordant with social components of gender. While most studies of gender development in people with 46,XY DSD have historically emphasized the importance of genes and hormones on gender identity and gender role, more recent evidence for a significant role for socialization exists and is considered here. For example, the influence of parents’ perceptions of, and reactions to, DSD are considered. Additionally, the impact of treatments for DSD such as receiving gonadal surgeries or genitoplasty to reduce genital ambiguity on the psychological development of people with 46,XY DSD is presented. Finally, the role of multi-disciplinary care including access to peer support for advancing medical, surgical and psychosexual outcomes of children and adults with 46,XY DSD, regardless of sex of rearing, is discussed.

Abstract Background Primary adrenal insufficiency (PAI) in children is a rare condition and potentially lethal. The clinical characteristics are non-specific. It may be manifested as a chronic condition or crisis. The etiologies of PAI in children are different from the adult population. Therefore, diagnostic investigation becomes challenging. Methods A retrospective study was conducted at The First Affiliated Sun Yat Sen University Pediatric Endocrine unit between September 1989 and July 2016. Results A total of 434 patients (237 males, 197 females) were identified as having PAI. Congenital adrenal hyperplasia (CAH) was the most frequent etiology (83.4%, n = 362, male:female = 174:188), of which 351 (97.2%) were 21-hydroxylase deficiency (21-OH) CAH. Non-CAH etiology accounted for 11.3% (n = 49, male:female = 47:2), of which 46 (93.9%) were of non-autoimmune. The etiologies of the 49 cases were adrenoleukodystrophy (ALD; n = 22), X-linked adrenal hypoplasia congenital (X-AHC; n = 20), autoimmune polyglandular syndrome (APS; n = 3), triple A syndrome (n = 2), steroidogenic factor 1 (SF-1) gene mutation (n = 1) and adrenalectomy (n = 1). The etiology was not identified for 23 patients (5.3%, male:female =16:7). Clinical symptoms were in accordance with the incidence of genital ambiguity (42.6%), digestive symptoms (vomiting and diarrhea) (35.5%), failure to thrive (26.5%), gonadal-associated symptom (premature puberty, sexual infantilism and amenorrhea) (21.2%), hyperpigmentation (9.7%), adrenal crisis (AC; 4.1%), neurological symptoms (3.2%), fatigue (2.5%) and prolonged jaundice (2.1%). Through physical examination, 58.5% were found to have hyperpigmentation. Conclusions This study spanned 29 years at our institution. The etiology of PAI in children was mostly of congenital forms, which exhibits a wide spectrum of clinical characteristics. For etiological diagnosis, chromosomal karyotyping is recommended for female phenotype patients.

Management of ambiguous genitalia is highly controversial. This condition was known previously as intersex and presently as disorders of sex development (DSD). There is no consensus regarding the choice, timing and method of sex assignment in neonates with DSD. Consensus conferences could not unify the views of various stakeholders and third parties. This article philosophically examines the nature and origin of such controversies. Misconception, bias and conflicting priorities are identified as the three cardinal sources of controversies. Conceptual duality of sexes, confused notion of sex and gender, bias towards penetrative intercourse, conflict between utopian ideals and reality, unwillingness to compromise are identified as perpetuators of controversies. Suggestions are made regarding sex assignment in various types of DSD based on the understanding of published literature and the author’s personal experience.
