RESUMEN

AIM: We aimed to identify the challenges in the management of sexual development abnormalities in a low-resource country. METHODS: The study was retrospective from January 2000 to December 2017 based on patient records from two pediatric surgery departments. Epidemiological, clinical, paraclinical, treatment, and outcome data were studied. RESULTS: We collected data on 13 patients (average age = 7.95 years). The sex of rearing was as follows: three females (23%), 10 males (77%). Atypical genitalia other than hypospadias represented the reason for consultation in 92% of the cases. We could not find complete hormonal analyses; testosterone levels were studied in 69.23% of cases. We found the following disorders of sexual development (DSD): four patients with 46,XX karyotype (30.77%), eight patients with 46,XY karyotype (61.53%), and one patient with 46,XX/XY karyotype. Four patients had medical treatment only, four had surgical treatment only, and one patient had medical and surgical treatment. The medical treatment comprised topical administration of androgen. The surgical treatment consisted of feminizing genitoplasty for one patient and masculinizing genital surgeries for two patients. Six of the 13 patients were lost to follow-up. CONCLUSION: The socioeconomic difficulties of the population and the lack of access to basic diagnostic and paraclinical methods, coupled with the negative cultural representations of the pathology, constitute the challenges in the management of DSD in our practice.

RESUMEN

OBJECTIVES: To determine trends in clinical practice for individuals with DSD requiring gonadectomy. DESIGN: Retrospective cohort study. METHODS: Information regarding age at gonadectomy according to diagnosis; reported sex; time of presentation to specialist centre; and location of centre from cases reported to the International DSD Registry and who were over 16 years old in January 2019. RESULTS: Data regarding gonadectomy were available in 668 (88%) individuals from 44 centres. Of these, 248 (37%) (median age (range) 24 (17, 75) years) were male and 420 (63%) (median age (range) 26 (16, 86) years) were female. Gonadectomy was reported from 36 centres in 351/668 cases (53%). Females were more likely to undergo gonadectomy (n = 311, P < 0.0001). The indication for gonadectomy was reported in 268 (76%). The most common indication was mitigation of tumour risk in 172 (64%). Variations in the practice of gonadectomy were observed; of the 351 cases from 36 centres, 17 (5%) at 9 centres had undergone gonadectomy before their first presentation to the specialist centre. Median age at gonadectomy of cases from high-income countries and low-/middle-income countries (LMIC) was 13.0 years (0.1, 68) years and 16.5 years (1, 28), respectively (P < 0.0001) with the likelihood of long-term retention of gonads being higher in LMIC countries. CONCLUSIONS: The likelihood of gonadectomy depends on the underlying diagnosis, sex of rearing and the geographical setting. Clinical benchmarks, which can be studied across all forms of DSD will allow a better understanding of the variation in the practice of gonadectomy.

RESUMEN

We have searched the literature for information on the risk of breast cancer (BC) in relation to gender, breast development, and gonadal function in the following 8 populations: 1) females with the Turner syndrome (45, XO); 2) females and males with congenital hypogonadotropic hypogonadism and the Kallmann syndrome; 3) pure gonadal dysgenesis (PGD) in genotypic and phenotypic females and genotypic males (Swyer syndrome); 4) males with the Klinefelter syndrome (47, XXY); 5) male-to-female transgender individuals; 6) female-to-male transgender individuals; 7) genotypic males, but phenotypic females with the complete androgen insensitivity syndrome, and 8) females with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome (müllerian agenesis). Based on this search, we have drawn 3 major conclusions. First, the presence of a Y chromosome protects against the development of BC, even when female-size breasts and female-level estrogens are present. Second, without menstrual cycles, BC hardly occurs with an incidence comparable to males. There is a strong correlation between the lifetime number of menstrual cycles and the risk of BC. In our populations the BC risk in genetic females not exposed to progesterone (P4) is very low and comparable to males. Third, BC has been reported only once in genetic females with MRKH syndrome who have normal breasts and ovulating ovaries with normal levels of estrogens and P4. We hypothesize that the oncogenic glycoprotein WNT family member 4 is the link between the genetic cause of MRKH and the absence of BC women with MRKH syndrome.

RESUMEN

We aimed to survey the monogenic causes of disorders of sex development (DSD) and thereby its prevalence in India. This study revealed mutations resulting in androgen insensitivity syndrome, 5α-reductase type 2 deficiency, and gonadal dysgenesis were commonly reported. Intriguingly, AR deficits were the most prevalent (32 mutations) and of 11/26 missense mutations were in exons 4-8 (encoding ligand binding domain). The unique features of SRD5A2 defects were p.R246Q (most prevalent) and p.G196S could be mutational hotspots, dual gene defects (p.A596T in AR and p.G196S in SRD5A2) in a patient with hypospadias and novel 8 nucleotide deletion (exon 1) found in a patient with perineal hypospadias. Deficits in SRY, WT1, DHH, NR5A1, and DMRT1 caused 46,XY gonadal dysgenesis. Notably, mutations in AR, SRD5A2, MAMLD1, WT1, and MAP3K1 have led to hypospadias and only one CYP19A1 mutation caused aromatase deficiency was reported to date. Data mining from various databases has not only reinforced the role of well-established genes (e.g., SRY, WT1, DHH, NR5A1, DMRT1, AR, SRD5A2, MAMLD1) involved in DSD but also provided us 12 more potential candidate genes (ACVR1, AMHR2, CTNNB1, CYP11A1, CYP19A1, FGFR2, FGF9, PRKACA, PRKACG, SMAD9, TERT, ZFPM2), which benefit from a close association with the well-established genes involved in DSD and might be useful to screen owing to their direct gene-phenotype relationship or through direct functional interaction. As more genes have been revealed in relation to DSD, we believe ultimately it holds a better scenario for therapeutic regimen. Despite the advances in translational medicine, hospitals are yet to adopt genetic testing and counseling facilities in India that shall have potential impact on clinical diagnosis.

RESUMEN

BACKGROUND: Evidence-based guidelines on evaluation of boys with proximal hypospadias for the possibility of a disorder of sex development (DSD) have yet to be developed. We aimed to investigate the incidence and diagnoses of DSD in patients with proximal hypospadias. METHODS: We retrospectively reviewed the records of consecutive boys who underwent proximal hypospadias repairs from 2006 to Sept 2017. Data collected included scrotal anomaly, testes position/palpability, micropenis, DSD investigations, and surgical techniques. RESULTS: 165 patients were eligible for the study. 14 (8.5%) were diagnosed to have DSD. The diagnoses were 46,XX testicular DSD [n = 1], 46,XY DSD [n = 7; partial gonadal dysgenesis (PGD) = 3; 5α-reductase type 2 deficiency = 3; 17α-hydroxylase deficiency = 1], Sex Chromosome DSD [n = 6; 45,X/46,XY PGD = 4; Klinefelter = 2]. 3/7 (43%) patients with PGD had gonadal germ cell neoplasms. Of the DSD patients, 6/14 (43%), 11/14 (79%) and 11/14 (79%) had undescended/impalpable testes, micropenis and penoscrotal transposition/bifid scrotum, respectively, significantly higher prevalence rates than those without DSD diagnosis (p-values <0.05). 10/14 (71.4%) DSD patients underwent 2-stage repair compared with 57/151 (37.7%) of others without DSD diagnosis (p = 0.01). CONCLUSIONS: Patients presenting with proximal hypospadias and one or more of the coexisting anomalies of micropenis, undescended/impalpable testes, and penoscrotal transposition/bifid scrotum should warrant DSD evaluation. Presence of bilaterally descended testes in scrotum does not preclude the possibility of DSD. LEVEL OF EVIDENCE: IV.

RESUMEN

PURPOSE: Surgical repair for proximal hypospadias has been associated with long-term success rates of 32-68%. In a prior study, outcomes for proximal hypospadias in patients with a diagnosis of disorders of sex development (DSD) were no different than those of patients without DSD. The objective of our study is to report our experience with proximal hypospadias repair in patients with and without DSD. METHODS: We retrospectively reviewed patients who underwent repair of proximal hypospadias between 2005 and 2016. Data collected included patient and disease characteristics, operative details, complications, and follow-up. The primary outcome was unplanned reoperation. RESULTS: Sixty seven patients were identified; 30 (44.8%) with DSD and 37 (55.2%) without DSD. Median follow-up was 28.3 months (IQR 18.9-45.7). 41 patients (61.2%) underwent at least one unplanned reoperation, median time to unplanned reoperation 10.3 months. More patients with DSD needed an unplanned reoperation (80 vs. 45.9%, p = 0.024). During the first 12 months after initial repair, there was no difference in unplanned reoperation rates (40 vs. 32.4%, p = 0.611), but there was a difference in the first 24 months post-operatively (76.7 vs. 43.2%, p = 0.007). On multivariate logistic regression, older age at initial repair (OR 1.144) and two stage repair (OR 7.644) were positively associated with unplanned reoperation in the first 2 years after repair. CONCLUSIONS: Proximal hypospadias repair is associated with an overall 61.2% reoperation rate regardless of associated DSD diagnosis. Patients with DSD are more likely to undergo an unplanned reoperation in the first 2 years after repair.

RESUMEN

This study aimed to describe the demographic characteristics, hospital utilizations, patterns of inpatient surgical management, and the overall state/regional variation in surgery rate among patients with disorders of sex development (DSD). We analyzed the Nationwide Inpatient Sample from 2001 to 2012 for patients younger than 21 years. DSD-related diagnoses and procedures were identified via International Classification of Diseases, Ninth Revision (ICD-9) codes. We identified a total of 43,968 DSD-related admissions. Of these, 73.4% of the admissions were designated as female and 642 (1.9%) were inpatient surgical admissions. Among neonates, less than 1% underwent any type of genital surgery. Nonsurgical admissions were associated with longer length of stay and higher cost. There was no significant regional variation in the rate of DSD surgeries, but we observed higher concentrations of DSD surgeries in states associated with tertiary referral centers.

RESUMEN

BACKGROUND: Ambiguous genitalia refers to a form of differences of sex development (DSD) wherein the appearance of the external genitalia is atypical. This rare condition presents challenges in decision-making and clinical management. Review of historical data may reveal areas for clinical research to improve care for patients with ambiguous genitalia. OBJECTIVE: This chart review was performed to identify patients with ambiguous genitalia, and to classify them as having 46,XX DSD, 46,XY DSD, or sex chromosome DSD. Within these categories, we looked at establishment of specific diagnoses, type and frequency of other congenital anomalies and neoplasms, and gender assignment, as well as incidence of gender reassignment and transition. METHODS: We performed a retrospective chart review of patients diagnosed with DSD conditions from 1995 to 2016 using ICD9 codes. For the purpose of this study, review was limited to individuals assessed to have neonatal "ambiguous genitalia" or "indeterminate sex." RESULTS: Review identified 128 patients evaluated for ambiguous genitalia from 22 years of experience (Figure). Approximately half of these (53%) had 46,XY karyotype, 35% had 46,XX, and the remaining 12% had sex chromosome aberrations. Diagnostic rate for 46,XX DSD was higher at 64%, all of which were congenital adrenal hyperplasia, while diagnostic rate for 46,XY DSD was 11.7% for a molecularly confirmed diagnosis and 24% if clinical diagnoses were included. The most common anomalies included cardiac anomalies in 28/128 (22%), skeletal anomalies in 19/128 (15%), and failure to thrive or growth problems in 19/128 (15%). Additional congenital anomalies were found in 53 out of 128 patients (41%). There were three reported neoplasms in this group: gonadoblastoma, hepatoblastoma, and myelodysplastic syndrome with monosomy 7. Gender assignment was consistent with chromosomes in approximately 90% of XX and XY patients. There were three recorded gender reassignments or transitions. DISCUSSION: Diagnostic rate for ambiguous genitalia is low, especially in 46,XY DSD. Most neonates were assigned gender consistent with their chromosomes. Given the high rate of associated anomalies, screening for cardiac or other anomalies in patients with ambiguous genitalia may be beneficial. CONCLUSION: Patients with ambiguous genitalia often have additional congenital anomalies. Establishment of a specific diagnosis is uncommon in 46,XY patients. A few patients have gender reassignment outside of the newborn period. Ongoing collection of clinical data on this population may reveal new information regarding long-term health, quality of life, and establishment of more diagnoses with improved molecular techniques.

RESUMEN

PURPOSE: Provide recommendations for the development of an interdisciplinary care (IDC) clinic for the treatment of youth with disorders/differences of sex development (DSD). DSD consist of a group of complex congenital medical disorders in which the development of chromosomal, gonadal, or anatomical sex is atypical. Youth with DSD require care from multiple specialized healthcare disciplines, including several medical specialties, surgery, nursing, and mental health. METHOD: Recommendations are based on an interdisciplinary care clinic model that allows for a team of relevant professionals who share knowledge, ideas, and responsibility of care. The framework established in this article is based largely on experiences at an established DSD clinic, as well as observations of multiple clinics across the United States. RESULTS: Preliminary outcome data on clinic adherence to treatment protocol under an IDC model are provided. CONCLUSIONS: To meet the diverse healthcare needs of youth with DSD, comprehensive care clinics are recommended; however, few such clinics exist in the United States. Establishing new comprehensive DSD clinics can be challenging due to the highly unique treatment of DSD, but the current paper expands the literature available to guide clinic development in the United States.

RESUMEN

Following the principles of care recommended in the 2006 Consensus Statement on Disorders of Sex Development (DSD), along with input from representatives of peer support and advocacy groups, this study surveyed DSD clinical management practices at healthcare facilities in the United States. DSD are congenital conditions in which development of chromosomal, gonadal, or anatomic sex is atypical. Facilities providing care for patients with DSD were targeted for participation. Specialty providers completed a survey with questions in six broad categories: Institution Information, Nomenclature and Care Guidelines, Interdisciplinary Services, Staff and Community Education, DSD Management, and Research. Twenty-two of 36 targeted sites (61%) participated. Differences were observed between sites with regard to what conditions were considered to be DSD. All sites reported some degree of involvement of pediatric urology and/or surgery and pediatric endocrinology in the care of DSD patients. Gynecology and neonatology were most frequently not represented. Wide variation was observed across sites in continuing education standards, obtaining informed consent for clinical procedures, and in specific clinical management practices. This survey is the first to assess DSD clinical management practices in the United States. The findings establish a baseline of current practices against which providers delivering care to these patients and their families can benchmark their efforts. Such surveys also provide a practical framework for collaboration in identifying opportunities for change that enhance health and quality of life outcomes for patients and families affected by DSD.

RESUMEN

Context: Adequate sex steroid hormone concentrations are essential for normal fetal genital development in early pregnancy. Our previous study demonstrated an inverse relationship between third-trimester di-2-ethyl hexyl phthalate exposure and total testosterone (TT) concentrations. Here, we examine early-pregnancy phthalates, sex steroid hormone concentrations, and newborn reproductive outcomes. Design: We examined associations between urinary phthalate metabolite concentrations in early pregnancy and serum free testosterone (FT), TT, estrone (E1), and estradiol (E2) in 591 woman/infant dyads in The Infant Development and Environment Study; we also examined relationships between hormones and newborn genital outcomes using multiple regression models with covariate adjustment. Results: E1 and E2 concentrations were 15% to 30% higher in relation to 1-unit increases in log monoisobutyl phthalate (MiBP), mono-2-ethyl hexyl phthalate, and mono-2-ethyl-5-oxy-hexyl phthalate concentrations, and E2 was 15% higher in relation to increased log monobenzyl phthalate (MBzP). FT concentrations were 12% lower in relation to 1-unit increases in log mono(carboxynonyl) phthalate (MCNP) and mono-2-ethyl-5-carboxypentyl phthalate concentrations. Higher maternal FT was associated with a 25% lower prevalence of having a male genital abnormality at birth. Conclusions: The positive relationships between MiBP, MBzP, and DEHP metabolites and E1/E2 are unique and suggest a positive estrogenic effect in early pregnancy. The inverse relationship between MCNP and DEHP metabolites and serum FT supports previous work examining phthalate/testosterone relationships later in pregnancy. Higher FT in relation to a 25% lower prevalence of male genital abnormalities confirms the importance of testosterone in early fetal development.

RESUMEN

Intersex in wild fish populations has received considerable attention in the scientific literature and public media. Conventional detection of testicular oocytes, the presence of immature oocytes within testis of male fish, commonly employs transverse sectioning of excised testis and is lethal. The present study used a nonlethal laparoscopic technique to collect biopsies of testis from black bass, entering the body cavity via the genital pore. Detection of testicular oocytes was compared between biopsy and conventional methods using 79 smallmouth bass (Micropterus dolomieu) from 8 sites and 68 largemouth bass (Micropterus salmoides) from 4 sites. The 2 methods performed similarly at sites where testicular oocyte severity was moderate or high (6 of 8 smallmouth bass sites), whereas transverse sectioning resulted in superior testicular oocyte detection at sites where severity was low (2 of 8 smallmouth bass sites and all 4 largemouth bass sites). In smallmouth bass, testicular oocyte prevalence by transverse and biopsy methods was strongly correlated across sites (r2 = 0.81) and severity reported by enumeration of testicular oocytes was moderately correlated across sites (r2 = 0.59). Survival of a subset of largemouth bass (n = 20) to 28 d after laparoscopic surgery was 90%. The present research indicates that laparoscopy may be useful for monitoring the prevalence and severity of testicular oocytes in Micropterus species, particularly when lethal sampling is precluded.

RESUMEN

The goal of this update regarding the diagnosis and care of persons with disorders of sex development (DSDs) is to address changes in the clinical approach since the 2005 Consensus Conference, since knowledge and viewpoints change. An effort was made to include representatives from a broad perspective including support and advocacy groups. The goal of patient care is focused upon the best possible quality of life (QoL). The field of DSD is continuously developing. An update on the clinical evaluation of infants and older individuals with ambiguous genitalia including perceptions regarding male or female assignment is discussed. Topics include biochemical and genetic assessment, the risk of germ cell tumor development, approaches to psychosocial and psychosexual well-being and an update on support groups. Open and on-going communication with patients and parents must involve full disclosure, with the recognition that, while DSD conditions are life-long, enhancement of the best possible outcome improves QoL. The evolution of diagnosis and care continues, while it is still impossible to predict gender development in an individual case with certainty. Such decisions and decisions regarding surgery during infancy that alters external genital anatomy or removes germ cells continue to carry risk.

RESUMEN

OBJECTIVE: To describe the profile of patients with genitourinary abnormalities treated at a tertiary hospital genetics service. METHODS: Cross-sectional study of 1,068 medical records of patients treated between April/2008 and August/2014. A total of 115 cases suggestive of genitourinary anomalies were selected, regardless of age. A standardized clinical protocol was used, as well as karyotype, hormone levels and genitourinary ultrasound for basic evaluation. Laparoscopy, gonadal biopsy and molecular studies were performed in specific cases. Patients with genitourinary malformations were classified as genitourinary anomalies (GUA), whereas the others, as sex differentiation disorders (SDD). Chi-square, Fisher and Kruskal-Wallis tests were used for statistical analysis and comparison between groups. RESULTS: 80 subjects met the inclusion criteria, 91% with SDD and 9% with isolated/ syndromic GUA. The age was younger in the GUA group (p<0.02), but these groups did not differ regarding external and internal genitalia, as well as karyotype. Karyotype 46,XY was verified in 55% and chromosomal aberrations in 17.5% of cases. Ambiguous genitalia occurred in 45%, predominantly in 46,XX patients (p<0.006). Gonadal differentiation disorders accounted for 25% and congenital adrenal hyperplasia, for 17.5% of the sample. Consanguinity occurred in 16%, recurrence in 12%, lack of birth certificate in 20% and interrupted follow-up in 31% of cases. CONCLUSIONS: Patients with SDD predominated. Ambiguous genitalia and abnormal sexual differentiation were more frequent among infants and prepubertal individuals. Congenital adrenal hyperplasia was the most prevalent nosology. Younger patients were more common in the GUA group. Abandonment and lower frequency of birth certificate occurred in patients with ambiguous or malformed genitalia. These characteristics corroborate the literature and show the biopsychosocial impact of genitourinary anomalies.

RESUMEN

OBJECTIVE: Improvements in diagnostic testing and genital repair have significantly advanced the management of disorders of sex development (DSD). Challenges however, still exist in the management of DSD. This study evaluated the types, challenges of surgical management, and outcome of DSD in south-east Nigeria. METHODS: Retrospective analysis of 39 children with DSD managed from January 2005 to December 2013 at the University of Nigeria Teaching Hospital, Enugu, Nigeria. RESULTS: Types of DSD were: 46, XX DSD in 17 (43.6 %) cases; 46, XY DSD 16 (41 %); Ovotesticular DSD 5 (12.8 %); and one (2.6 %) 46, XY Ovotesticular DSD. Median age at definitive gender assignment was 3 years (range 2 months-14 years). Gender assignment was female for 20 (51.3 %; all 46, XX DSD, one each of 46, XY DSD, Ovotesticular DSD and 46, XY Ovotesticular DSD), and male for 19 (48.7 %; 15 of 46, XY DSD, 4 of Ovotesticular DSD). Eight cases reared as male before presentation required gender reassignment after evaluation and counselling. Genital repair was undertaken at mean age of 4.1 years (range 6 months-14 years). After average follow-up of 22.5 months (range 1 month-7 years), a total of eleven (28.2 %) developed procedure-related complications. Challenges were delayed diagnosis, inadequate diagnostic facilities, and need for gender reassignment. CONCLUSION: There is a wide spectrum of DSD in our setting. Time to diagnosis, evaluation, and outcome may be improved by public enlightenment initiative, focused education of healthcare personnel and provision of relevant diagnostic facilities through enhanced funding and collaboration.

RESUMEN

In Indonesia, disorders of sex development (DSDs) are not well recognized and medical care for affected individuals is scarce. Consequently, many patients live with ambiguous genitalia and appearance. We compared reported outcomes on body image, sexual functioning, and sexual orientation of 39 adults with DSDs (aged 18 to 41) and 39 healthy controls matched for gender, age, and residential setting (urban, suburban, rural). Differences in gender and treatment status (treated or untreated) were also explored. On body image, adults with DSDs reported dissatisfaction with sex-related body parts. Compared to the matched controls, women with DSDs reported greater sexual distress, and men with DSDs reported lower erectile and ejaculation frequencies, and more dissatisfaction with sexual life but not with sexual desire and activities. Men with DSDs who had undergone genital surgery reported higher erectile and ejaculation frequencies than untreated men. More women than men in the DSDs group reported a nonexclusive heterosexual orientation. DSDs and infertility had a great impact on sexuality. Fear of ostracism complicated DSD acceptance. Findings were compared to those of Western studies. Based on these results, education about DSDs and their psychosexual consequences may help reduce the sexual distress and problems in adults with DSDs and improve quality of life.

RESUMEN

OBJECTIVE: We aimed to assess how the diagnosis and determination of gender identity of disorders of sex development (DSD) is different in a developing country from Western medicine, and whether a pediatric surgery department can determine the underlying diagnosis and use simple tools to determine the likely gender identity (GI). MATERIAL AND METHODS: We reviewed the records of DSD patients admitted to the Department of Pediatric Surgery, Chittagong Medical College & Hospital (CMCH), Chittagong, Bangladesh, from January 2006 to December 2012 and performed a cross-sectional study on GI and gender-related behavior in these patients during the year 2012. DSD boys and girls answered a GI interview and had their gender role behavior assessed by observations of structural toy play and analyzed for differences in scores. RESULTS: This cohort of DSD patients presented in mid-childhood (6 months-16 years, mean 6.9 years) rather than infancy, and 30% came from consanguineous unions. Congenital adrenal hyperplasia (CAH) constituted only 11 of 50 (22%) of the DSD cohort, and not all families had access to steroid hormone replacement. A simple assessment of GI and gender-related behavior allowed effective gender assignment, as there was significant difference between DSD boys and girls in GI and gender-related behavior score. CONCLUSIONS: DSD management in Bangladesh provides some unique challenges because of limited resources. A national reference laboratory for biochemical and genetic testing and development of a quaternary referral center for DSD patients will be helpful. Continued use of the GI interview and gender-related behavior study will enable effective interim decisions about diagnosis and management.

RESUMEN

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.
