Long-term outcomes and molecular analysis of a large cohort of patients with 46,XY disorder of sex development due to partial gonadal dysgenesis.

BACKGROUND: Follow-up data on patients with 46,XY partial gonadal dysgenesis (PGD) until adulthood are scarce, making information on prognosis difficult. OBJECTIVE: To analyse the long-term outcomes of patients with 46,XY PGD regarding testosterone production, germ cell tumour risk, genotype and psychosexual adaptation. METHODS: A retrospective longitudinal study of 33 patients (20 assigned male and 13 patients assigned female at birth). Molecular diagnosis was performed by Sanger sequencing or by targeted massively parallel sequencing of 63 genes related to disorders of sex development (DSDs). RESULTS: Age at first and last visit ranged from 0.1 to 43 and from 17 to 53 years, respectively. Spontaneous puberty was observed in 57% of the patients. During follow-up, six of them had a gonadectomy (four due to female gender, and two because of a gonadal tumour). At last evaluation, five of six patients had adult male testosterone levels (median 16.7 nmol/L, range 15.3-21.7 nmol/L) and elevated LH and FSH levels. Germ cell tumours were found in two postpubertal patients (one with an abdominal gonad and one patient with Frasier syndrome). Molecular diagnosis was possible in 11 patients (33%). NR5A1 variants were the most prevalent molecular defects (n = 6), and four of five patients harbouring them developed spontaneous puberty. Gender change was observed in four patients, two from each sex assignment group; all patients reported satisfaction with their gender at final evaluation. Sexual intercourse was reported by 81% of both gender and 82% of them reported satisfaction with their sexual lives. CONCLUSION: Spontaneous puberty was observed in 57% of the patients with 46,XY PGD, being NR5A1 defects the most prevalent ones among all the patients and in those with spontaneous puberty. Gender change due to gender dysphoria was reported by 12% of the patients. All the patients reported satisfaction with their final gender, and most of them with their sexual life.

Quality of life in a large cohort of adult Brazilian patients with 46,XX and 46,XY disorders of sex development from a single tertiary centre.

OBJECTIVE: Few studies have focused on the quality of life (QoL) of patients with disorders of sex development (DSD). Our aim was to evaluate QoL in DSD patients with defined diagnoses followed until adulthood in a single tertiary centre. PATIENTS AND METHODS: Adult patients with DSD (56 patients with 46,XX DSD - 49 with female social sex and 7 with male social sex as well as 88 patients with 46,XY DSD - 54 with female social sex and 34 with male social sex). MEASUREMENTS: QoL using WHOQOL-Bref questionnaire. RESULTS: Both patients with 46,XX DSD and patients with 46,XY DSD had similar QoL scores on the WHOQOL-Bref, comparable to the scores of the Brazilian general population. The chronological age at the start of treatment was negatively and significantly associated with general QoL score. Patients with male social sex DSD had better scores on the psychological domain than patients with female social sex DSD, as found in the Brazilian general population. In addition, among the 46,XY DSD group, the male social sex patients had better QoL compared with the female social sex patients. There was a positive and significant correlation between sexual performance and general QoL, although it explained only 4% of the variability of the general QoL score. The most influencing variables were general health, positive feelings and spirituality, religion and personal beliefs, each of them contributing with 18% of the variability of the general QoL score. CONCLUSION: Our large cohort of adult patients with DSD, which was followed by a multidisciplinary team in a single tertiary centre, had good QoL in adulthood; in addition, late treatment compromised the QoL of patients with DSD, whereas sexual performance has little influence on QoL.

Quality of life of patients with 46,XX and 46,XY disorders of sex development.

Disorders of sex development (DSD) result from abnormalities in the complex process of sex determination and differentiation. An important consideration to guide the assignment of social sex in newborns with ambiguous genitalia is the quality of life (QoL) of these patients in adulthood. The rarity of most DSD conditions makes it difficult to conduct a long-term follow-up of affected patients through adulthood. This review of papers on the QoL of DSD patients evaluated in developing and developed countries by qualitative and quantitative instruments revealed a large spectrum of QoL, ranging from very poor to similar to, or even better than, the normal population. A more adequate QoL was found in patients from tertiary centres, indicating that the medical care of DSD patients should be multidisciplinary and carried out by specialized teams.

Long-term followup of a large cohort of patients with ovotesticular disorder of sex development.

PURPOSE: We present the followup of a large cohort of patients with ovotesticular disorder of sex development treated at a single tertiary center. MATERIALS AND METHODS: We reviewed the records of 20 patients with ovotesticular disorder of sex development. We retrospectively evaluated clinical and surgical characteristics. A prospective study was also performed, including evaluation of surgical results, gonadal function, sexual activity and voiding symptoms of these patients during adulthood. RESULTS: All patients had ambiguous genitalia, including 18 with a 46,XX karyotype and 2 with a 46,XX/46,XY karyotype. Gender assignment at birth was male in 13 patients and female in 7. Three females were later reassigned to the male gender. Bilateral gonadectomy was performed in 10 patients. Testicular tissue was preserved in 8 males and ovarian tissue was preserved in 2 females. Average followup was 25 years (range 4 to 46). Puberty started spontaneously in 14 patients between ages 11 and 14 years. Seven patients showed spontaneous puberty after conservative gonadal surgery and 4 required hormonal replacement during adulthood. The most frequent complications in males were urethral fistula in 6 and late urethral stenosis in 3. Two patients with urethral stenosis had symptoms 10 years postoperatively. One female presented with temporary dyspareunia. In adulthood 8 males and 2 females reported sexual activity. All male patients reported orgasm and 2 reported ejaculation. CONCLUSIONS: Male gender assignment was more prevalent. Long-term followup revealed adequate pubertal development and sexual activity. Complications involving the urethra developed frequently in male patients.

Sexuality and fertility desire in a large cohort of individuals with 46, XY differences in sex development.

OBJECTIVE: To analyze aspects of sexual life and fertility desire among 46, XY DSD people, including those who changed their gender. METHODS: It is a cross-sectional study including 127 adults (> 16 years of age) with 46, XY DSD (83 females; 44 males) from a Single Brazilian Tertiary-Care Medical Center. RESULTS: Sexual fantasies and masturbation were more frequent in 46, XY DSD males, whereas orgasm and sexual life satisfaction were similar in both genders. More 46, XY DSD men than women had a long-term romantic relationship. 46, XY DSD women with prenatal androgen exposure reported more fear of being romantically rejected. External genitalia appearance at birth did not impact the sexuality of 46, XY DSD women after surgical genital treatment had been completed. Overall, the sexual life was similar between 46, XY men assigned as males and those who changed to the male gender. Regarding sexual orientation, most self-reported as heterosexual (91% and 92% of women and men, respectively). The desire for fertility had a similar prevalence in both genders, but more women than men considered infertility a barrier to a long-term romantic relationship. Twelve individuals (7 males) had children; 10 out of 12 have adopted children. CONCLUSION: Fertility desire was shared among 46, XY DSD people, regardless of gender. Prenatal androgen exposure reduced the desire for motherhood in 46, XY women. 46, XY DSD people who changed from female to male gender presented similar sexual parameters as those assigned as males. Among females, virilized genitalia at birth did not affect sexuality once the surgical treatment is completed.

Long-term surgical outcome of masculinizing genitoplasty in large cohort of patients with disorders of sex development.

PURPOSE: We evaluated the results of masculinizing genitoplasty in a large cohort of patients with disorders of sex development treated at a single public tertiary center. MATERIALS AND METHODS: We evaluated 52 patients with 46,XY and 7 with 46,XX disorders of sex development with proximal hypospadias and genital ambiguity reared as males who had undergone surgery between 1965 and 2008. Mean +/- SD followup was 14.1 +/- 9.2 years and median age at last examination was 22 years, with 38 patients having reached adulthood. Morphological result and urinary stream were evaluated by a physician. Urinary and sexual symptoms, and satisfaction with surgical results were assessed by questionnaire. RESULTS: Mean penile length at diagnosis was compared between 46,XY patients and showed that those with 5alpha-reductase 2 deficiency had the shortest penile length (-5.4 +/- 1.2 SD). At the last clinical evaluation following surgical and hormonal treatment mean +/- SD penile length in 38 adults was 7.5 +/- 2.1 cm (range 4 to 12), corresponding to -4.3 +/- 1.3 SD (-6.5 to -1.5). All but 2 patients had penile length less than -2 SD. At that time mean penile length remained shorter in patients with 5alpha-reductase 2 deficiency (-5.4 +/- 1 SD) compared to those with testosterone production deficiency or indeterminate disorders of sex development (p <0.05). There was no statistical difference between mean penile length before and after treatment in all etiological groups (p >0.05). Morphological results were good in 43% of patients, fair in 54% and poor in 3%. The most common complications were urethral fistula (51%) and urethral stenosis (22%). Dribbling after voiding was the most frequent urinary symptom. Satisfaction with surgical results was reported by 89% of patients. Among adults 87% were sexually active, with 64% reporting normal sexual activity. CONCLUSIONS: Most patients with 46,XY disorders of sex development were satisfied with long-term results of masculinizing genitoplasty, although specific complaints about small penile length, sexual activity and urinary symptoms were frequent. New surgical approaches should be developed to ensure full satisfaction in adulthood among patients with disorders of sex development.

Impact of schooling in the HIV/AIDS prevalence among Brazilian transgender women.

Objective Discrimination and bullying are common conditions among LGBT people. During schooling, these practices compromising education. The aim of this study is to evaluate educational attainment among Brazilian transgender women (TW) and how their education level affects the risk of HIV infection. Study design a cross-sectional population-based study. Subjects and methods 95 adult TW were selected. Information concerning verbal and physical aggression, school dropout, school years (SY), and educational level were assessed. HIV status was screened using a fourth-generation immunoassay followed by western blot testing. Results The mean of SY was 9.1 ± 3.8 ys. The mean age at school dropout was 16.3 ± 3.4 ys old. Verbal aggression was reported by 83%, physical by 48%, and 18% of the TW dropped out school immediately after being physically assaulted. Participants who suffered physical aggression attended school for almost 4 years less than those participants who did not suffer this abuse (OR = -3.96, p < 0.0001). A similar result was found for verbal aggression (OR = -4.35; p < 0.0001). HIV/AIDS prevalence was 18% (n = 17). The mean of SY among HIV/AIDS positive and negative individuals were 6.8 ± 43 versus 9.7 ± 3, respectively (p = 0.004). Lower education was associated with higher frequency of HIV/AIDS among TW and this relationship was sustained after adjustment for injectable drug use and sex work (OR = 0.79, p = 0.04). Conclusion Among Brazilian TW, lower education level was a risk factor associated with HIV. The reasons for low schooling among TW are multifactorial, but verbal and physical harassment strongly contribute for it.

Psychosexual Aspects, Effects of Prenatal Androgen Exposure, and Gender Change in 46,XY Disorders of Sex Development.

CONTEXT: In 46,XY disorders of sexual development (DSD) patients, several factors may affect psychosexual development, leading to gender identity discrepancy and gender change later in life. Prenatal sexual steroid exposure and external genital virilization are considered to influence human psychosexual development, but their roles not completely understood yet. DESIGN: A total of 144 individuals (18 to 60 years of age) with a clinical/molecular diagnosis of 46,XY DSD from a single tertiary center were enrolled. Psychosexual outcomes (gender role, gender identity, and sexual orientation) were assessed using questionnaires and psychological test. The Sinnecker score was used for genital virilization measurement. Prenatal androgen exposure was estimated according to 46,XY DSD etiology. RESULTS: We found a positive association between prenatal androgen exposure and male psychosexual outcomes. Alternatively, prenatal estrogen exposure, age of gonadectomy, and the degree of external genital virilization did not influence any psychosexual outcome. There were 19% (n = 27) with gender change, which was associated with prenatal androgen exposure (P < 0.001) but not with the external genital virilization. The median age of gender change was 15 years, but most of the patients reported the desire for gender change earlier. CONCLUSIONS: Prenatal androgen exposure influenced psychosexual development in 46,XY DSD favoring male psychosexuality in all psychosexual outcomes, whereas the degree of external genital virilization did not influence these outcomes. The organizational effect of sexual steroids on psychosexuality at puberty appears to be weak in comparison with the prenatal effects. Prenatal androgen exposure also influenced female-to-male gender change frequency. All 46,XY DSD conditions with prenatal androgen exposure must be followed for gender issues in their management.

Sexuality and fertility desire in a large cohort of individuals with 46, XY differences in sex development

Abstract Objective: To analyze aspects of sexual life and fertility desire among 46, XY DSD people, including those who changed their gender. Methods: It is a cross-sectional study including 127 adults (> 16 years of age) with 46, XY DSD (83 females; 44 males) from a Single Brazilian Tertiary-Care Medical Center. Results: Sexual fantasies and masturbation were more frequent in 46, XY DSD males, whereas orgasm and sexual life satisfaction were similar in both genders. More 46, XY DSD men than women had a long-term romantic relationship. 46, XY DSD women with prenatal androgen exposure reported more fear of being romantically rejected. External genitalia appearance at birth did not impact the sexuality of 46, XY DSD women after surgical genital treatment had been completed. Overall, the sexual life was similar between 46, XY men assigned as males and those who changed to the male gender. Regarding sexual orientation, most self-reported as heterosexual (91% and 92% of women and men, respectively). The desire for fertility had a similar prevalence in both genders, but more women than men considered infertility a barrier to a long-term romantic relationship. Twelve individuals (7 males) had children; 10 out of 12 have adopted children. Conclusion: Fertility desire was shared among 46, XY DSD people, regardless of gender. Prenatal androgen exposure reduced the desire for motherhood in 46, XY women. 46, XY DSD people who changed from female to male gender presented similar sexual parameters as those assigned as males. Among females, virilized genitalia at birth did not affect sexuality once the surgical treatment is completed.

46,XY disorder of sex development (DSD) due to 17ß-hydroxysteroid dehydrogenase type 3 deficiency.

17ß-hydroxysteroid dehydrogenase 3 deficiency consists of a defect in the last phase of steroidogenesis, in which androstenedione is converted into testosterone and estrone into estradiol. External genitalia range from female-like to atypical genitalia and most affected males are raised as females. Virilization in subjects with 17ß-HSD3 deficiency occurs at the time of puberty and several of them change to male social sex. In male social sex patients, testes can be safely maintained, as long as they are positioned inside the scrotum The phenotype of 46,XY DSD due to 17ß-HSD3 deficiency is extremely variable and clinically indistinguishable from other causes of 46,XY DSD such as partial androgen insensitivity syndrome and 5α-reductase 2 deficiency. Laboratory diagnosis is based on a low testosterone/androstenedione ratio due to high serum levels of androstenedione and low levels of testosterone. The disorder is caused by a homozygous or compound heterozygous mutations in the HSD17B3 gene that encodes the 17ß-HSD3 isoenzyme leading to an impairment of the conversion of 17-keto into 17-hydroxysteroids. Molecular genetic testing confirms the diagnosis and provides the orientation for genetic counseling. Our proposal in this article is to review the previously reported cases of 17ß-HSD3 deficiency adding our own cases.

Assessment of stress levels in girls with central precocious puberty before and during long-acting gonadotropin-releasing hormone agonist treatment: a pilot study.

BACKGROUND: The objective of the study was to determine the stress levels of girls with central precocious puberty (CPP) before and during treatment with a long-acting gonadotropin-releasing hormone agonist (GnRHa). METHODS: The Child Stress Scale (CSS) was used for 10 unrelated girls with CPP before and after the first year of GnRHa treatment. The CSS is divided into four subscales (physical, psychological, psychological with depressive component and psychophysiological reactions). Through a quantitative analysis, it is possible to classify stress into four stages: alarm, resistance, near-exhaustion and exhaustion. RESULTS: At diagnosis, 90% of the girls showed stress levels scores at the alarm or resistance stage on at least one subscale, mostly in terms of physical and psychological reactions. The mean total stress score was significantly higher before when compared to after GnRHa treatment (43.4±15.6 vs. 28.9±9.7; p<0.05). The mean stress scores obtained in all subscales, except the one on psychophysiological reactions, were significantly higher before GnRHa treatment. CONCLUSIONS: Higher stress levels were a common finding in girls with CPP before treatment. The significant stress level reduction after pubertal suppression reinforces the idea that sexual precocity is a stressful condition in children. The CSS might be a useful tool for psychological assessment of patients with CPP.

Successful Live Birth in a Woman With 17α-Hydroxylase Deficiency Through IVF Frozen-Thawed Embryo Transfer.

CONTEXT: Congenital adrenal hyperplasia (CAH) due to 17α-hydroxylase deficiency in 46,XX patients is characterized by primary amenorrhea, absent or incomplete sexual maturation, infertility, low serum levels of estradiol, and elevated progesterone (P). There were no previous reports of singleton live births from such women. OBJECTIVE: To describe the first successful singleton live birth in a female with CAH due to 17α-hydroxylase deficiency. CASE DESCRIPTION: A 26-year-old Brazilian woman with CAH associated with 17α-hydroxylase deficiency due to the compound heterozygote mutation (p.W406R/P428L) in the CYP17A1 gene expressed the desire to conceive. In vitro fertilization (IVF) was recommended due to the complexity of the disorder. The first attempt of treatment failed despite the production of viable embryos. At the second IVF attempt, all viable embryos were frozen due to inadequate endometrial development associated with prematurely elevated serum P during ovarian stimulation. Subsequently, a long-acting GnRH agonist and oral dexamethasone were used to lower ovarian and adrenal P overproduction. Once serum levels of P were < 1 ng/mL, endometrial preparation with estradiol valerate and frozen-thawed embryo transfer were performed, resulting in a singleton pregnancy. Estradiol supplementation was completely suspended by 14 weeks of gestation. She delivered at 30 weeks and 4 days due to acute fetal distress. The puerperium was uneventful; the newborn was discharged in good conditions 5 weeks after birth. CONCLUSION: A successful live birth was achieved in a woman with 17-hydroxylase deficiency through IVF, cryopreservation of all embryos, and frozen-thawed embryo transfer after adequate endometrial preparation.

Clinical, hormonal, ovarian, and genetic aspects of 46,XX patients with congenital adrenal hyperplasia due to CYP17A1 defects.

OBJECTIVE: To perform a clinical, biochemical, and molecular evaluation of patients with CYP17A1 defects, including ovarian imaging. DESIGN: Retrospective study. SETTING: Tertiary care center. PATIENT(S): Sixteen patients with congenital adrenal hyperplasia due to CYP17A1 defects with a median chronological age of 20 years and belonging to 10 unrelated families. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Clinical and biochemical parameters, molecular diagnosis, ovarian imaging, and therapeutic management. RESULT(S): Seventy-one percent of patients presented with primary amenorrhea, 50% had no breast development, and pubic hair was absent or sparse in all patients; 88% had high blood pressure at diagnosis. Basal LH and P levels were high, and androgen levels were low in all patients. Ultrasound revealed ovarian enlargement in 68.7% and ovarian macrocysts in 62.5% of patients before treatment; three patients had a previous surgical correction of ovarian torsion or rupture. Molecular analysis revealed inactivating CYP17A1 mutations in all patients. The most prevalent mutation was p.W406R, and one patient bore a novel p.G478S/p.I223Nfs*10 compound heterozygous mutation. Treatment with dexamethasone, estrogen, and P resulted in reduction of ovarian volume. CONCLUSION(S): Amenorrhea, absent/sparse pubic hair, hypertension, and ovarian macrocysts, whichincrease the risk of ovarian torsion, are important elements in the diagnosis of 46,XX patients with CYP17A1 defects. High basal P levels in patients with hypergonadotropic hypogonadism point to the diagnosis of CYP17A1 defects. Fertility can be achieved in these patients with novel reproductive techniques.

Clinical, hormonal, behavioral, and genetic characteristics of androgen insensitivity syndrome in a Brazilian cohort: five novel mutations in the androgen receptor gene.

Androgen insensitivity syndrome (AIS) is caused by mutations in the androgen receptor gene and is associated with a variety of phenotypes in 46,XY individuals, ranging from phenotypic women [complete form (CAIS)] to men with minor degrees of undervirilization or infertility [partial form (PAIS)]. We studied 32 subjects with male pseudohermaphroditism from 20 families (9 CAIS, 11 PAIS) with the following criteria for AIS: 46,XY karyotype, normal male basal and human chorionic gonadotropin-stimulated levels of serum testosterone and steroid precursors, gynecomastia at puberty, and, in prepubertal patients, a family history suggestive of X-linked inheritance. The entire coding region of the androgen receptor gene was analyzed, and mutations were found in all families with CAIS and in eight of 11 families with PAIS. Fifteen different mutations were identified, including five (S119X, T602P, L768V, I898F, and P904V) that have not been described previously. Detailed clinical and hormonal features were compared with genotype in 25 subjects with AIS and confirmed by mutational analysis. LH hormone levels and the LH x testosterone product were high in all postpubertal subjects with AIS. All subjects with PAIS maintained at postpubertal age the gender identity and social sex that was assigned to them in infancy, in contrast to other forms of pseudohermaphroditism.

DSD due to 5α-reductase 2 deficiency - from diagnosis to long term outcome.

Most of the patients with 5α-RD 2 deficiency are reared in the female social sex due to their severely undervirilized external genitalia but ~60% who have not been submitted to orchiectomy in childhood undergo male social sex change at puberty. In our cohort of 30 cases from 18 families, all subjects were registered in the female social sex except for two children-one who had an affected uncle and the other who was diagnosed before being registered. The majority of the patients were satisfied with the long-term results of their treatment and surprisingly, penile length was not associated with satisfactory or unsatisfactory sexual activity. Steroid 5α-RD2 deficiency should be included in the differential diagnosis of all newborns with 46,XY DSD with normal testosterone production before gender assignment or any surgical intervention because these patients should be considered males at birth.

Novel mutations in CYP11B1 gene leading to 11 beta-hydroxylase deficiency in Brazilian patients.

BACKGROUND: Deficiency of 11 beta-hydroxylase results in the impairment of the last step of cortisol synthesis. In females, the phenotype of this disorder includes different degrees of genital ambiguity and arterial hypertension. Mutations in the CYP11B1 gene are responsible for this disease. OBJECTIVE: The objective of the study was to screen the CYP11B1 gene for mutations in two unrelated Brazilian females with congenital adrenal hyperplasia due to 11 beta-hydroxylase deficiency. DESIGN: The coding and intron-exon junction regions of CYP11B1 were totally sequenced. A putative splice mutation was further investigated by minigene transcription. RESULTS: We report two novel CYP11B1 mutations in these Brazilian patients. An Arabian Lebanese descendent female was found to be homozygous for a cytosine insertion at the beginning of exon 8, changing the 404 arginine to proline. It alters the open reading frame, creating a putative truncated protein at 421 residue, which eliminates the domain necessary for the association of heme prosthetic group. A severely virilized female was homozygous for the g.2791G>A transition in the last position of exon 4. This nucleotide is also part of 5' intron 4 donor splice site consensus sequence. Minigene experiments demonstrated that g.2791G>A activated an alternative splice site within exon 4, leading to a 45-bp deletion in the transcript. The putative translation of such modified mRNA indicates a truncated protein at residue 280. CONCLUSIONS: We describe two novel mutations, g.4671_4672insC and g.2791G>A, that drastically affects normal protein structure. These mutations abolish normal enzyme activity, leading to a severe phenotype of congenital adrenal hyperplasia due to 11 beta-hydroxylase deficiency.

Aspectos psicossociais e sexuais de pacientes com distúrbios do desenvolvimento sexual a longo prazo / Long term psychosocial and psychosexual aspects of patients with disorders of sex development

INTRODUÇÃO: Os pacientes com distúrbios do desenvolvimento sexual (DDS) constituem um desafio para os profissionais que se empenham no seu tratamento e acompanhamento. São raros os estudos na área psicológica com acompanhamento destes pacientes a longo prazo. Este estudo tem por objetivo avaliar os aspectos psicossociais e sexuais em relação ao diagnóstico etiológico, avaliar a influência de diversas variáveis na manutenção ou mudança da identidade de gênero nos pacientes que atingiram a idade adulta e a qualidade de vida numa grande coorte de pacientes com DDS 46,XY e 46,XX acompanhados em um mesmo serviço a longo prazo. MÉTODOS: O estudo teve caráter principalmente retrospectivo e foi realizado em pacientes com DDS de ambos os sexos acompanhados até o período pós-puberal ou idade adulta, num total de 151 pacientes maiores de 15 anos; destes, 55 pacientes apresentavam cariótipo 46,XX e 96 cariótipo 46,XY, tendo sido incluído neste ultimo grupo 6 pacientes que apresentavam cariótipo 46,XY em mosaicismo com a linhagem 45,X. O diagnóstico etiológico do DDS foi estabelecido pela avaliação clínica, citogenética, hormonal e por imagem em todos os casos e na maioria deles complementada pelo diagnóstico molecular. Todos os pacientes foram submetidos a tratamento clinico, psicológico e cirúrgico. Os instrumentos utilizados para a avaliação psicológica foram: a entrevista semi-estruturada com aplicação de um questionário específico com 192 questões, desenvolvido para avaliar os aspectos sociais, profissionais e sexuais, o teste projetivo do HTP para auxiliar na identificação da identidade de gênero e o questionário Whoqol-Bref para avaliar a qualidade de vida. RESULTADOS: A atribuição do sexo social feminino foi predominante em ambos os grupos com DDS. Houve mudança do sexo social em 20% dos pacientes com DDS 46,XY e em 14% dos pacientes com DDS 46,XX. Houve associação significativa da mudança para o gênero masculino nos pacientes do grupo DDS 46,XY por...

INTRODUCTION: Patients with disorders of sex development (DSD) constitute a challenge for professionals working in their treatment and follow-up. Studies of patients with DSD have been focused on dissatisfaction in adulthood with sex assigned at birth. However, other parameters, such as psychosocial adjustment, sexual function, psychological health, social integration and the quality of life are rarely described. This study aims to evaluate the professional and psychosocial aspects, in order to identify the variables involved in gender identity and sexual orientation of a large cohort of patients with DSD 46 XY and, 46, XX and also assess the quality of life of patients in adulthood. METHODS: The study was mainly retrospective and was conducted in patients with DSD of both sexes followed until puberty or adulthood, a total of 151 patients older than 15 years; of these, 55 patients had 46, XX karyotype and 96 of them 46,XY karyotype, having been included in the latter group 6 patients who had 46, XY karyotype in mosaicism with the 45, X lineage. Etiological diagnosis of DSD was established by clinical evaluation, cytogenetics, hormonal and image studies in all cases and most of them complemented by molecular diagnosis. All patients underwent surgical and psychological treatment. Instruments used for psychological evaluation were: a semi-structured interview with application of a specific questionnaire with 192 questions developed to assess the social, professional and sexual aspects. The projective HTP test was used to assess gender identity and the Whoqol-Bref questionnaire to evaluate the quality of life. RESULTS: The female social sex assignment was prevalent in both groups with DSD. A change of assigned sex was found in 20% of the 46, XY DSD patients and in 14% of the 46,XX DSD patients. There was a significant association between the change to male social sex with DSD 46, XY due to 5 alpha-RD2 deficiency when compared with DSD 46,XY group due to defects...

Normal bone density in male pseudohermaphroditism due to 5alpha- reductase 2 deficiency

Bone is an androgen-dependent tissue, but it is not clear whether the androgen action in bone depends on testosterone or on dihydrotestosterone. Patients with 5alpha-reductase 2 deficiency present normal levels of testosterone and low levels of dihydrotestosterone, providing an in vivo human model for the analysis of the effect of testosterone on bone. OBJECTIVE: To analyze bone mineral density in 4 adult patients with male pseudohermaphroditism due to 5alpha-reductase 2 deficiency. RESULTS: Three patients presented normal bone mineral density of the lumbar column (L1-L4) and femur neck, and the other patient presented a slight osteopenia in the lumbar column. CONCLUSION: Patients with dihydrotestosterone deficiency present normal bone mineral density, suggesting that dihydrotestosterone is not the main androgen acting in bone
