Abstract
Sex development relies on the sex-specific action of gene networks to differentiate the bipotential gonads of the growing fetus into testis or ovaries, followed by the differentiation of internal and external genitalia depending on the presence or absence of hormones. Differences in sex development (DSD) arise from congenital alterations during any of these processes, and are classified depending on sex chromosomal constitution as sex chromosome DSD, 46,XY DSD or 46,XX DSD. Understanding the genetics and embryology of typical and atypical sex development is essential for diagnosing, treating and managing DSD. Advances have been made in understanding the genetic causes of DSD over the past 10 years, especially for 46,XY DSD. Additional information is required to better understand ovarian and female development and to identify further genetic causes of 46,XX DSD, besides congenital adrenal hyperplasia. Ongoing research is focused on the discovery of further genes related to typical and atypical sex development and, therefore, on improving diagnosis of DSD.

Abstract
BACKGROUND Forty-six ,XY Differences/Disorders of Sex Development (DSD) are characterized by a broad phenotypic spectrum ranging from typical female to male with undervirilized external genitalia, or more rarely testicular regression with a typical male phenotype. Despite progress in the genetic diagnosis of DSD, most 46,XY DSD cases remain idiopathic. METHODS To determine the genetic causes of 46,XY DSD, we studied 165 patients of Tunisian ancestry, who presented a wide range of DSD phenotypes. Karyotyping, candidate gene sequencing, and whole-exome sequencing (WES) were performed. RESULTS Cytogenetic abnormalities, including a high frequency of sex chromosomal anomalies (85.4%), explained the phenotype in 30.9% (51/165) of the cohort. Sanger sequencing of candidate genes identified a novel pathogenic variant in the SRY gene in a patient with 46,XY gonadal dysgenesis. An exome screen of a sub-group of 44 patients with 46,XY DSD revealed pathogenic or likely pathogenic variants in 38.6% (17/44) of patients. CONCLUSION Rare or novel pathogenic variants were identified in the AR, SRD5A2, ZNRF3, SOX8, SOX9 and HHAT genes. Overall our data indicate a genetic diagnosis rate of 41.2% (68/165) in the group of 46,XY DSD.

Abstract
UNLABELLED Consanguinity increases the risk of hereditary diseases including disorders of sex development (DSD). There are minimal data on DSD in the highly consanguineous population of Saudi Arabia. This study reports the molecular genetics of a series of patients with different types of DSD. METHODS We enrolled 77 patients from 47 families with DSD. DNA was isolated from peripheral leucocytes. Genes of interest were amplified by polymerase chain reaction and subsequently sequenced. RESULTS Overall, 77 patients from 47 families (44 of them are consanguineous) had a total of 29 mutations; 16 of them were described before and 13 were novel mutations. The most common condition was 5-α reductase (SRD5A2) deficiency (25 patients from 18 families) and the most common mutation was a splice site mutation in intron 1 (c.282-2A>G). The next most common condition was 11-β hydroxylase (CYP11B1) deficiency where 19 patients from 10 families had 8 mutations (7 of them are novel). Other mutations affected CYP17A1 with 2 novel and 2 known mutations in 7 patients; HSD3B2 with 2 known mutations in 11 patients of 4 families; StAR with 1 novel and 1 known mutations in 4 patients; NR0B1 with 1 novel mutation in 2 siblings; HSD17B3 with 1 known mutation in 3 siblings; LHCGR with 1 novel mutation in 2 siblings; and AR with 1 novel and 3 known mutations in 4 unrelated patients. CONCLUSION In the highly consanguineous and homogeneous population of Saudi Arabia, SRD5A2 and CYP11B1 deficiencies are common causes of DSDs. Other DSDs occur less frequently but often with novel mutations.

Abstract
Disorders/differences of sex development (DSD) comprise a group of congenital disorders that affect the genitourinary tract and usually involve the endocrine and reproductive system. The aim of this work was to identify genetic variants responsible for disorders of human urogenital development in a cohort of Egyptian patients. This three-year study included 225 patients with various DSD forms, referred to the genetic DSD and endocrinology clinic, National Research Centre, Egypt. The patients underwent thorough clinical examination, hormonal and imaging studies, detailed cytogenetic and fluorescence in situ hybridization analysis, and molecular sequencing of genes known to commonly cause DSD including AR, SRD5A2, 17BHSD3, NR5A1, SRY, and WT1. Whole exome sequencing (WES) was carried out for 18 selected patients. The study revealed a high rate of sex chromosomal DSD (33%) with a wide array of cytogenetic abnormalities. Sanger sequencing identified pathogenic variants in 33.7% of 46,XY patients, while the detection rate of WES reached 66.7%. Our patients showed a different mutational profile compared with that reported in other populations with a predominance of heritable DSD causes. WES identified rare and novel pathogenic variants in NR5A1, WT1, HHAT, CYP19A1, AMH, AMHR2, and FANCA and in the X-linked genes ARX and KDM6A. In addition, digenic inheritance was observed in two of our patients and was suggested to be a cause of the phenotypic variability observed in DSD.

Abstract
Background Worldwide people in disorder of sex development (DSD) faces multiple barriers while seeking their social rights, particularly healthcare services. We aimed to explore the healthcare opportunities available to them, using patterns of healthcare utilization and difficulties faced by DSD population in accessing healthcare services in Bangladesh. Methods Data from a total of 945 DSD population and 71 medical staff were analyzed, collected from three major divisions (Dhaka, Chittagong, and Rajshahi) in Bangladesh during the period of January to December of 2017. A structured questionnaire was used to collect data via face-to-face interviews. Descriptive statistic was used to determine the frequencies of the visit by the DSD population in healthcare facilities as well as to analyze difficulties experienced by the DSD population in getting healthcare services. Multivariate regression analysis was used to explore the association between perceived barriers in getting healthcare services and failures of the DSD population to receive the healthcare services. Results Present data revealed that around 80% of DSD population sought healthcare services from government healthcare facilities, where the overall success rate in getting healthcare services was less than 50%. The DSD population reported a number of reasons for failures in getting healthcare services, including non-friendly interaction by non-clinical hospital’s staff, non-friendly interaction by physicians, public fright as general people do not want to mingle with a DSD person, undesirable excess public interest in DSD individuals, and limitation of the treatment opportunities of hospitals to merely male or female patients. Among the stated reasons, the most frequently reported reason was non-friendly interaction by physicians (50.27%), followed by undesirable excess public interest in DSD individuals (50.16%). Conclusion DSD population in Bangladesh have limited access to healthcare facilities and facing multiple barriers to get healthcare services. Initiatives from the government and social organizations are important to ensure their access to healthcare services.

Abstract
INTRODUCTION The frequency of gender dysphoria (GD) among 46,XX congenital adrenal hyperplasia (CAH) patients is unknown. These data are needed to put into perspective the debate about the timing of reconstructive surgery and possible male-raising of the most severely virilized children. OBJECTIVE To analyze the frequency of female to male GD between 46,XX individuals raised as females; to identify subgroups with higher chances of showing GD; to describe the results of male-raising among 46,XX CAH patients. MATERIALS AND METHODS Analytic/descriptive literature review (January 1988 to April 2018). RESULTS Female-raised patients frequently report the desire to be male, adopt male-typical behavior and are frequently homosexual/bisexual as adults, but this does not correspond to GD. Declared GD among 46,XX CAH patients attained 9% of the reported cohorts, generally in late adolescence/adulthood. We could not prove a relationship between inadequate treatment, null-genotype, late diagnoses, a higher degree of virilization, type of CAH or higher levels of androgens and female to male GD, but this may be due to statistical limitations. Male gender raised patients (MGR) were 10.1% of CAH cohorts included in this review, mostly from underdeveloped countries, with a high proportion of late diagnoses (76.3%) and familial choices. GD was more common in this group than among female-raised patients. Opting for male gender relates to a short final height, the need for multiple surgeries, surgical castration before puberty and infertility. CONCLUSION Both male to female and female to male GD may present in 46,XX CAH patients in a contemporaneous cohort. The proportion of GD is higher among patients raised as males. DSD patients sexual maladjustments are complex and not comparable to the transgender population. Many 46,XX CAH patients with GD define themselves as gender-fluid and do not seek for legal/formal transition. Male-raising Prader 4/5 46,XX CAH patients imply infertility and multiple surgeries. There is no proof that any subgroup of CAH is more prone to GD, despite null genotypes, salt wasting phenotypes and Prader 4/5 cases being related to male-typical behavior and female homosexuality. TYPE OF STUDY Descriptive/analytic non-systematic REVIEW. LEVEL OF EVIDENCE 3.

Abstract
CONTEXT Limited data are available on the exact incidence of disorders of sex development (DSD) with genital ambiguity at birth. OBJECTIVE To determine frequency of ambiguous genitalia in newborns. DESIGN Prospective multicenter study. SETTING Three tertiary care hospitals. PATIENTS OR OTHER PARTICIPANTS All 14,177 babies born during the study period were included. MAIN OUTCOME MEASURES All newborns were examined at birth; data on weeks of gestation, birth weight, and length were collected. A structured questionnaire was used for data collection. Quigley and Prader scales were used for phenotypic grading. Clinical and genetic investigations were performed. RESULTS Eighteen babies with ambiguous genitalia were found among 14,177 newborns (1.3/1000). Fifteen newborns had 46,XY DSD, one had 46,XX congenital adrenal hyperplasia, and one had 45,X/46,XY mixed gonadal dysgenesis. Karyotype analysis was not done in one baby who died in the neonatal period. The ratio of prematurity was higher in the DSD group (44% vs 11%; P < 0.001) and the ratio of small for gestational age was also higher in the DSD group (22% vs 5%; P = 0.007). Eight babies with DSD had mothers who had additional medical conditions, such as preeclampsia, depression, insulin resistance, and gestational diabetes mellitus. CONCLUSION The frequency of ambiguous genitalia was higher than in previous studies, but, as with any experiment, the finding should be met with caution because this study was conducted in tertiary care hospitals. In addition, lower birth weight in the DSD group supports the hypothesis that early placental dysfunction might be important in the etiology of male genital anomalies.

Abstract
OBJECTIVE An important goal in treating children with congenital adrenal hyperplasia (CAH) is to achieve a normal final adult height (FH). The aim of this study was to describe the clinical presentations and evaluate linear growth and possible factors affecting it in children with CAH. METHODS This is a retrospective study of 56 patients with CAH followed up in a tertiary center for 11 years. Patient's data including demographics, clinical, anthropometric, and laboratory information at presentation and during follow-up period were collected from medical records. RESULTS Fifty-six children (31 females) with CAH were seen at KAMC-Jeddah over 11-year period and 91% were 21-hydroxylase deficient. Of these, 46.4% had hyponatremia and 28.6% had hyperkalemia (21.4% had hyponatremia and hyperkalemia) at presentation. Positive family history was documented in 53.6%. Ambiguous genitalia were present in 72% of females and the majority required corrective surgery. Males had significantly decreased HtSDS versus females and females had significantly higher body mass index. The HtSDS of children who had had higher 17OHP or salt-losing crisis during treatment was significantly lower than those who had normal 17OHP and those who did not have salt-losing crisis, respectively. CONCLUSION The final height outcome in our patients with CAH treated with glucocorticoids is lower than the population norm. Proper control of the disease clinically and biochemically through strict compliance to medical therapy as well as close clinical and laboratory monitoring is an important key to achieve normal final adult height in these patients. Side effects, including overweight, obesity, and hypertension are true risk associations and need timely diagnosis and early management.

In Islam, the person with somatic sex ambiguity due to a disorder of sex development (DSD), such as 46,XX congenital adrenal hyperplasia or 46,XY androgen insensitivity, is recognized as khunsa. Two types of khunsa are distinguished: wadhih (discernible) and musykil (intractable). A recent fatwa (religious edict) in Malaysia decreed that it is permissible for male-assigned patients from these two groups to have gender reassignment surgery to female following diagnosis; however, the religious authority has yet to rule on the reassignment from female to male, if requested. The different schools of law in Islam agree on some aspects of gender-related issues like the position of khunsa in prayer congregations, but differ in their opinions on others such as property inheritance and bathing rituals. For purposes of illustration, this article includes three case reports on Muslim patients with DSD in Malaysia, focusing on issues of gender assignment: (1) a patient with 46,XX CAH, assigned as female, requesting reassignment to male; (2) a patient with 46,XX CAH, assigned female, and gender dysphoric, but undecided on the gender to be; and (3) a patient with 46,XY complete gonadal dysgenesis, raised female due to her phenotype at birth, diagnosed late, at age 18 years, and content to remain female. Gender-related issues from the perspective of Islamic jurisprudence are highlighted and discussed. To ensure holistic care, health-service providers involved in the care of Muslim patients with DSDs need to be aware of the Islamic perspectives on gender-related issues and involve expert religious authorities.

Abstract
Congenital adrenal hyperplasia (CAH) is a group of disorders affecting adrenal steroid synthesis. The most common form, 21-hydroxylase deficiency, leads to decreased production of cortisol and aldosterone with increased androgen secretion. In classic CAH glucocorticoid treatment can be life-saving, and provides symptom control, but must be given in an unphysiological manner with the risk of negative long-term outcomes. A late diagnosis or a severe phenotype or genotype has also a negative impact. These factors can result in impaired quality of life (QoL), increased cardiometabolic risk, short stature, osteoporosis and fractures, benign tumors, decreased fertility, and vocal problems. The prognosis has improved during the last decades, thanks to better clinical management and nowadays the most affected patients seem to have a good QoL. Very few patients above the age of 60 years have, however, been studied. Classifying patients according to genotype may give additional useful clinical information. The introduction of neonatal CAH screening may enhance long-term results. Monitoring of different risk factors and negative consequences should be done regularly in an attempt to improve clinical outcomes further.

Abstract
BACKGROUND AND OBJECTIVES Ambiguous genitalia is a complex, medical and social emergency. The aim of this study is to present our experience over two decades, focusing on the pattern and clinical presentation. DESIGN AND SETTING A retrospective study conducted in the pediatric endocrine clinic at a university hospital Saudi Arabia during the period 1989-2008. PATIENTS AND METHODS Medical records of children with ambiguous genitalia were reviewed and the genitalia described. RESULTS Of the 81 children with ambiguous genitalia, 53 (65.4%) patients were genetically females (46XX), with congenital adrenal hyperplasia being the common cause in 51 (96.5%) patients. Hyperpigmentation, variable degrees of salt wasting and a family history of a similar problem helped in diagnosis. Male genetic sex (46XY) was present in only 28 (34.6%) patients with a diversity of causes; multiple congenital anomalies in 9 (32.1%), local anorectal anomalies in 2 (7.1%), congenital adrenal hyperplasia (3-β-hydroxysteroid dehydrogenase deficiency) in 2 (7.14%), 5-α-reductase deficiency in 4 (14.28%), partial androgen insensitivity in 3 (10.7%), complete androgen insensitivity in 4 (14.28%), and hypogonadotrophin deficiency in 4 (14.3%).Twenty-five (47.2%) of females were wrongly assigned as males, where only two (7.1%) males were wrongly assigned as females. CONCLUSION Ambiguous genitalia, currently termed disorders of sex development (DSD), is not uncommon in our community. Increased awareness, a detailed history, and a careful physical examination, coupled with appropriate laboratory and radiological investigations aid in early diagnosis and avoid serious sequelae.

Abstract
A spectrum of myths and misconceptions about congenital adrenal hyperplasia (CAH) is prevalent among the parents of affected children in India. The perceptions of parents may affect several aspects of these children's management, and to explore these perceptions we carried out a cross-sectional questionnaire-based descriptive study during May 2010. Twenty-eight individuals (17 males and 11 females), parents of 22 affected children aged < 5 years, completed the questionnaire. Their responses showed the prevalence among the parents of misconceptions about CAH. These misconceptions were resulting in potentially harmful practices, and in addition there was immense societal pressure on the families as a result of ignorance and myths about the disorder. There is a need for regular CAH education and interaction programs to provide an acceptable platform for the parents and patients, where their concerns can be expressed and shared and their requirements addressed appropriately by a multidisciplinary team.

Abstract
The syndrome of male pseudohermaphroditism, caused by a deficiency of the enzyme 5-alpha reductase, results in a selective decrease in dihyrotestosterone. Culture is an important part of the context in which decisions are made on sex assignment of patients with abnormalities of the external genitalia. In Turkey, patients with ambiguious genitalia are diagnosed very late and corrective surgery is usually performed during or after puberty. Here we present a case with 5-alpha reductase deficiency who was diagnosed at puberty and followed-up for 10 years.

Abstract
More than 90% of cases of congenital adrenal hyperplasia (CAH, the inherited inability to synthesize cortisol) are caused by 21-hydroxylase deficiency. Females with severe, classic 21-hydroxylase deficiency are exposed to excess androgens prenatally and are born with virilized external genitalia. Most patients cannot synthesize sufficient aldosterone to maintain sodium balance and may develop potentially fatal "salt wasting" crises if not treated. The disease is caused by mutations in the CYP21 gene encoding the steroid 21-hydroxylase enzyme. More than 90% of these mutations result from intergenic recombinations between CYP21 and the closely linked CYP21P pseudogene. Approximately 20% are gene deletions due to unequal crossing over during meiosis, whereas the remainder are gene conversions--transfers to CYP21 of deleterious mutations normally present in CYP21P. The degree to which each mutation compromises enzymatic activity is strongly correlated with the clinical severity of the disease in patients carrying it. Prenatal diagnosis by direct mutation detection permits prenatal treatment of affected females to minimize genital virilization. Neonatal screening by hormonal methods identifies affected children before salt wasting crises develop, reducing mortality from this condition. Glucocorticoid and mineralocorticoid replacement are the mainstays of treatment, but more rational dosing and additional therapies are being developed.

Abstract
The belief that Homo sapiens is absolutely dimorphic with the respect to sex chromosome composition, gonadal structure, hormone levels, and the structure of the internal genital duct systems and external genitalia, derives from the platonic ideal that for each sex there is a single, universally correct developmental pathway and outcome. We surveyed the medical literature from 1955 to the present for studies of the frequency of deviation from the ideal male or female. We conclude that this frequency may be as high as 2% of live births. The frequency of individuals receiving "corrective" genital surgery, however, probably runs between 1 and 2 per 1,000 live births (0.1-0.2%). Am. J. Hum. Biol. 12:151-166, 2000.

Abstract
OBJECTIVE To improve the initial assessment of ambiguous genitalia in infants. SUBJECTS AND METHODS Using a specially devised scoring system, the external genitalia (external masculinization score, EMS, range 0-12) and internal reproductive structures (internal masculinization score, IMS, range 0-10) were assessed in 426 male newborns and 291 cases of ambiguous genitalia. RESULTS In normal male newborns, the median (10th centile) EMS was 11 (10). In the affected infants, the sex of rearing was male in 202 and female in 89 cases, respectively. The median (10-90th centile) EMS in those cases reared male, at 3.5 (2-8), was significantly higher than in cases reared as females, at 2 (1-6) (P < 0.001). The median IMS in cases reared as males and females was the same, at 10, but the scatter of values was higher for males (10-90th centile, 4-10) than for females (0-10) (P = 0.01). Infants reared as females were more likely to have a micropenis, a uterus and/or a urogenital sinus, but there were 12 cases where the sex of rearing was male despite the presence of a uterus; five infants without micropenis were reared as female and 23 with a urogenital sinus were reared as male. CONCLUSION The masculinization score provides a standardized format to summarize clinical features in newborn infants with ambiguous genitalia. Gender assignment does not solely depend on the appearance of the external genitalia and the nature of internal sexual organs.

Abstract
Sexual ambiguity is a complex and often confusing medical problem. In addition to the life-threatening adrenal crises which may accompany some forms, ambiguity of the genitalia may lead to incorrect sex assignment by parents and/or health personnel. Children who present to medical attention beyond the neonatal period constitute a challenging problem due to the grave consequences of this condition. Thirty cases in whom sex reassignment was indicated were seen at King Khalid University Hospital, Riyadh, over a 10-year period. Of these, 27 (90%) were genetic females (20 were 21- and seven were 11-hydroxylase deficient) and three (10%) were genetic males (two partial androgen insensitive and one 5alpha-reductase deficient). All genetic males who were incorrectly assigned as females accepted reassignment. But 9 out of 27 (33%) of the genetic females who were incorrectly assigned as males refused reassignment. Preference for male sex assignment, delayed diagnosis and sociocultural circumstances seem to be the contributing factors for refusal. A national consensus about this important issue strengthened by the existing religious recommendations in demanded.

Abstract
Eighty-two children (30 males and 52 females) with congenital adrenal hyperplasia (CAH) were seen at King Khalid University Hospital (KKUH) over a 10-year period. Of these, 74 (90.2%) were Saudis and eight (9.8%) non-Saudis. Fifty-nine (72%) patients were 21-hydroxylase deficient. Of these, 56 (95%) had variable degrees of salt depletion. Nineteen (23.2%) patients had a deficiency of 11-ss-hydroxylase enzyme and four (4.8%) showed deficiency of 3-ss-hydroxysteroid dehydrogenase. The consanguinity rate was high (71.2%) and positive family history was documented in 45.8%. Thirty-nine infants deaths occurred within 25 families. The diagnosis was often delayed. Of the 52 females, 27 (52%) were initially assigned male sex. These results indicate the importance of physicians' awareness and the need for a neonatal screening program for early detection and appropriate management.

Abstract
Ambiguous genitalia represents a true medical and social emergency which needs a multi-disciplinary team approach for elucidation. The paediatric radiologist plays an important role in defining the genital anatomy which remains one of the most important factors in sex determination. Aiming to compare the predictive value of pelvic ultrasonography and genitography in sex determination in patients with ambiguous genitalia, we retrospectively reviewed the medical records of 69 patients, 53 females and 16 males, where both procedures were employed. In female pseudohermaphroditism, the presence of a uterus with or without vagina was predicted in 46 (86.8%) patients by ultrasound compared with 44 (83%) patients in whom a genitogram revealed a vagina +/- uterus. In six (11.3%) patients, a genitogram revealed a male-type urethra. The combination of ultrasound and genitogram, however, was more sensitive and predicted the presence of a uterus with or without vagina in 52 (98.1%) patients. In male pseudo-hermaphroditism, there was no false positive by ultrasound, and a genitogram revealed a male-type urethra in 12 (75%) patients. In conclusion, although real time pelvic ultrasonography is less invasive than genitography, its yield in elucidating genital anatomy is comparable. The combination of both procedures is more informative and has a better yield.
