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.

Gender identity in patients with 5-alpha reductase deficiency raised as females.

BACKGROUND AND OBJECTIVE: 5-Alpha reductase type 2 deficiency (5-ARD) is a rare disorder of sex development. The lack of 5-alpha reductase, an enzyme that converts testosterone into dihydrotestosterone, results in external genitalia that may appear female, or predominantly male, albeit undervirilized, or, more often, ambiguous. METHODS: This study describes a series of patients with 5-ARD raised as female, focusing on aspects related to gender identity. Following a retrospective chart review, patients with 5-ARD were invited to return to the clinic to enable their gender identity to be assessed using an 11-item structured in-house questionnaire. The Golombok-Rust Inventory of Sexual Satisfaction was applied to patients who had initiated their sexual life. RESULTS: Six patients aged >15 years with 5-ARD and raised as female were included. Most patients were diagnosed late: two before and four after puberty. The mean length of the phallus was 2.8 cm (0.5-5.0). Reasons for seeing a doctor included genital appearance (n = 3), amenorrhea/absence of breast development (n = 2), and changes in gender role attitudes (n = 1). According to the gender identity assessment, 4 patients identified as female, 1 as male, and 1 as both genders. Only the patient identified as male requested gender re-assignment. Of the two patients who had initiated their sexual life, sexual satisfaction was found to be good in one and poor in the other due to vaginal discomfort during intercourse. CONCLUSION: In the present series, the majority of undervirilized patients with a diagnosis of 5-ARD raised as female were in complete conformation with being female and described themselves as heterosexual. The more virilized patients were those least in conformity with their female-assigned gender.

Growth Hormone Deficiency Causing Micropenis: Lessons Learned From a Well-Adjusted Adult.

This report of a 46,XY patient born with a micropenis consistent with etiology from isolated congenital growth hormone deficiency is used to (1) raise the question regarding what degree testicular testosterone exposure to the central nervous system during fetal life and early infancy has on the development of male gender identity, regardless of gender of rearing; (2) suggest the obligatory nature of timely full disclosure of medical history; (3) emphasize that virtually all 46,XY infants with functional testes and a micropenis should be initially boys except some with partial androgen insensitivity syndrome; and (4) highlight the sustaining value of a positive long-term relationship with a trusted physician (R.M.B.). When this infant presented, it was commonly considered inappropriate to gender assign an infant male whose penis was so small that an adult size was expected to be inadequate, even if the karyotype was 46,XY, and testes were functional. Concomitantly, female gender assignment was considered the appropriate decision, believing that parental rearing in the assigned gender was considered the major factor determining established adult gender identity. Full disclosure of medical information was considered inappropriate. Progress in appreciating the complexities of gender identity development, which is not yet completely understood, and sexuality, coping ability, and outcome data has resulted in a change of practice in initial gender assignment. A 46,XY individual with functional testes and verified androgen responsiveness should be assigned and reared as male, regardless of penis size. Without androgen responsiveness, the multiple factors must be carefully considered and disclosed.

Steroid 5α-reductase 2 deficiency leads to reduced dominance-related and impulse-control behaviors.

The enzyme steroid 5α-reductase 2 (5αR2) catalyzes the conversion of testosterone into the potent androgen 5α-dihydrotestosterone. Previous investigations showed that 5αR2 is expressed in key brain areas for emotional and socio-affective reactivity, yet the role of this enzyme in behavioral regulation remains mostly unknown. Here, we profiled the behavioral characteristics of 5αR2 heterozygous (HZ) and knockout (KO) mice, as compared with their wild-type (WT) littermates. While male 5αR2 KO mice displayed no overt alterations in motoric, sensory, information-processing and anxiety-related behaviors, they exhibited deficits in neurobehavioral correlates of dominance (including aggression against intruders, mating, and tube dominance) as well as novelty-seeking and risk-taking responses. Furthermore, male 5αR2 KO mice exhibited reduced D2-like dopamine receptor binding in the shell of the nucleus accumbens - a well-recognized molecular signature of social dominance. Collectively, these results suggest that 5αR2 is involved in the establishment of social dominance and its behavioral manifestations. Further studies are warranted to understand how the metabolic actions of 5αR2 on steroid profile may be implicated in social ranking, impulse control, and the modulation of dopamine receptor expression in the nucleus accumbens.

Genetic approach to ambiguous genitalia and disorders of sex development: What clinicians need to know.

Genetic tools such as microarray and next-generation sequencing have initiated a new era for the diagnosis and management of patients with disorders of sex development (DSDs). These tools supplement the traditional approach to the evaluation and care of infants, children, and adolescents with DSDs. These tests can detect genetic variations known to be associated with DSDs, discover novel genetic variants, and elucidate novel mechanisms of gene regulation. Herein, we discuss these tests and their role in the management of patients with DSDs.

Psychosexual Outcome Among Iranian Individuals With 5α-Reductase Deficiency Type 2 and Its Relationship With Parental Sexism.

INTRODUCTION: Few studies exist on the psychosexual outcome of homogeneous groups of individuals with 5α-reductase deficiency type 2 (5α-RD-2) and the relation between gender changes and parental hostile and benevolent sexism, which are two components of ambivalent sexism that assume a stereotypical approach toward women in an overtly negative way or a chivalrous, seemingly positive way. AIM: To report on the psychosexual outcome of individuals with 5α-RD-2 and to investigate its relation to the level of parental sexism in a relatively large sample of Iranians with 5α-RD-2. METHODS: Twenty participants (mean age = 19.5 years, SD = 6.345) with a molecularly confirmed diagnosis of 5α-RD-2 who were assigned the female gender at birth and raised as female were included in the study. Participants and their parents were interviewed and their medical records were assessed. Parents also completed the Ambivalent Sexism Inventory (ASI), which includes hostile and benevolent sexism subscales. MAIN OUTCOME MEASURES: Psychosexual outcome and parental hostile and benevolent sexism measurements. RESULTS: Twelve of 20 participants (60%) were diagnosed with gender identity disorder not otherwise specified (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision). Ten of these transitioned to the male gender. The other 10 participants (50%), including the two diagnosed with gender identity disorder not otherwise specified, continued living in a female gender role. When comparing the ASI subscale scores between families of participants who changed their gender and those who did not, no significant difference was found for ASI total and hostile sexism scores, but there was a difference for benevolent sexism (P = .049): those whose daughters had changed their gender had higher benevolent sexism scores. CONCLUSION: The high prevalence of gender change and gender dysphoria reported in the literature was confirmed in this relatively large and homogeneous sample of Iranians with 5-α-RD-2 raised as female. Prenatal exposure to testosterone is hypothesized to play a role in the development of gender identity and sexual orientation, but parental attitudes also might be important. Although gender change in individuals with 5-α-RD-2 is often attributed to high levels of hostile sexism in some cultures, our findings show this to be associated with benevolent sexism.

Steroid 5α-reductase 2 deficiency.

Dihydrotestosterone is a potent androgen metabolite formed from testosterone by action of 5α-reductase isoenzymes. Mutations in the type 2 isoenzyme cause a disorder of 46,XY sex development, termed 5α-reductase type 2 deficiency and that was described forty years ago. Many mutations in the encoding gene have been reported in different ethnic groups. In affected 46,XY individuals, female external genitalia are common, but Mullerian ducts regress, and the internal urogenital tract is male. Most affected males are raised as females, but virilization occurs at puberty, and male social sex develops thereafter with high frequency. Fertility can be achieved in some affected males with assisted reproduction techniques, and adults with male social sex report a more satisfactory sex life and quality of life as compared to affected individuals with female social sex.

Phenotype, genotype and gender identity in a large cohort of patients from India with 5α-reductase 2 deficiency.

Deficiency of the 5α-reductase 2 enzyme impairs the conversion of testosterone to dihydrotestosterone (DHT) and differentiation of external genitalia, seminal vesicles and prostate in males. The present study describes the phenotype, genotype and gender identity in a large cohort of patients with 5αRD2. All patients underwent detailed clinical evaluation, hormonal profile, karyotyping and molecular analysis of the SRD5A2 gene. The molecular analysis of the SRD5A2 gene showed the presence of mutant alleles in 24 patients. We found 6 novel mutations IVS(1-2) T>C, p.A52T, 188-189insTA, 904-905ins A, p.A12T and p.E57X in our patients. All patients had ambiguous genitalia and the degrees of under-virilization ranged from penoscrotal hypospadias and microphallus to clitoromegaly. The position of gonads was variable in patients with same mutation. All the patients with mutations in the SRD5A2 gene had male gender identity. Those reared as female had gender dysphoria and underwent gender reassignment. Though a specific genotype-phenotype correlation could not be established in our patient but confirming the diagnosis of 5αRD2 with assessment of the SRD5A2 gene may help in appropriate gender assignment.

Quality of Life and Psychological Adjustment of Women Living with 46,XY Differences of Sex Development.

BACKGROUND: Progressive care improvement for differences of sex development (DSD), regarding diagnosis communication, psychological, medical and surgical management has been claimed. AIM OF THE STUDY: To assess clinical management, quality of life (QoL) and the general psychosocial adjustment of individuals with 46,XY DSD. Some differences related to age at diagnosis are investigated. DESIGN: Cross-sectional study using standardized questionnaires. POPULATION: Forty-three Caucasian females with 46,XY DSD (self declared diagnoses: complete androgen insensitivity syndrome, n = 34; complete gonadal dysgenesis, n = 1; 5α-reductase deficiency, n = 4; Leydig cell hypoplasia, n = 1; unknown diagnosis, n = 3; age years: 31.5 ± 9.6 [range 18-57 years]). SETTING: University Hospitals. METHODS: Subjects were required to fill in questionnaires (ABCL, WHOQOL, dedicated 17-item questionnaire). Academic and socioeconomic data were compared with those of the Italian population. QoL and psychological data were compared with those of a comparison group (46,XX healthy females: n = 43; age, years: 34.5 ± 9.7, range 22-51 years). RESULTS: Present sample of women living with 46,XY DSD were well adapted and were higher achievers than controls, both in educational and professional life. They showed good QoL, but they appeared less satisfied in psychological and social areas. They had borderline mean scores and statistically higher scores than the comparison group for depression, anxiety, internalizing and externalizing problems. Younger persons living with a 46,XY DSD showed better psychosocial adjustment than older ones. Younger women showed lower age at diagnosis communication. Psychological support was more often proposed at the time of diagnosis communication to younger individuals, and they undertook it more frequently than older ones. CONCLUSIONS: Italian people living with 46,XY DSD were well adapted and successful; they reported a good QoL but showed higher degree of psychological distress than the comparison group. Lower psychological distress in younger women could indicate some positive effects of changes in management.

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.

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.

Otoacoustic emissions, auditory evoked potentials and self-reported gender in people affected by disorders of sex development (DSD).

Both otoacoustic emissions (OAEs) and auditory evoked potentials (AEPs) are sexually dimorphic, and both are believed to be influenced by prenatal androgen exposure. OAEs and AEPs were collected from people affected by 1 of 3 categories of disorders of sex development (DSD) - (1) women with complete androgen insensitivity syndrome (CAIS); (2) women with congenital adrenal hyperplasia (CAH); and (3) individuals with 46,XY DSD including prenatal androgen exposure who developed a male gender despite initial rearing as females (men with DSD). Gender identity (GI) and role (GR) were measured both retrospectively and at the time of study participation, using standardized questionnaires. The main objective of this study was to determine if patterns of OAEs and AEPs correlate with gender in people affected by DSD and in controls. A second objective was to assess if OAE and AEP patterns differed according to degrees of prenatal androgen exposure across groups. Control males, men with DSD, and women with CAH produced fewer spontaneous OAEs (SOAEs) - the male-typical pattern - than control females and women with CAIS. Additionally, the number of SOAEs produced correlated with gender development across all groups tested. Although some sex differences in AEPs were observed between control males and females, AEP measures did not correlate with gender development, nor did they vary according to degrees of prenatal androgen exposure, among people with DSD. Thus, OAEs, but not AEPs, may prove useful as bioassays for assessing early brain exposure to androgens and predicting gender development in people with DSD.

Sexual quality of life of individuals with 46,XY disorders of sex development.

INTRODUCTION: There has recently been a growing acceptance that it is not only heterosexual functioning of surgically adjusted genitalia which should be considered when measuring the treatment outcome of persons with disorders of sex development (DSD) but also their overall sexual quality of life (SexQoL). AIM: A comprehensive cross-sectional investigation of SexQoL of persons with 46,XY DSD. METHODS: Forty-seven persons with 46,XY DSD (age 17-60 years) were examined by means of a questionnaire on various aspects of SexQoL. Scores were compared to a nonclinical convenience sample consisting of 145 women. Data were analyzed separately for diagnostic subgroups. Furthermore, persons whose external genitalia had been surgically corrected were compared with persons whose genitalia had been left unaltered. MAIN OUTCOME MEASURES: The Multidimensional Scale of Sexuality, the German Questionnaire on Feelings of Inadequacy in Social and Sexual Situations (FUSS), items on sexual dysfunctions according to DSM-IV-TR and self-constructed measures on sexual-activity history (e.g., previous sexual experience), sexual anxieties, and satisfaction with overall sex life and sexual function comprised the standardized assessment instruments. RESULTS: Compared with the nonclinical group, persons with 46,XY DSD had more often no partner (P = 0.056), felt more insecure in social (Mdn(DSD) = 17.0, Mdn(comparison) = 12.0, P = 0.001) and sexual situations (Mdn(DSD) = 17.0, Mdn(comparison) = 11.0, P = 0.006), had more sexual problems (Mdn(DSD) = 4.0, Mdn(comparison) = 3.0, P = 0.001), and were less satisfied with overall sex life (Mdn(DSD) = 3.0, Mdn(comparison) = 4.0, P = 0.000) and sexual function (Mdn(DSD) = 4.0, Mdn(comparison) = 4.0, P = 0.000). Results were inconsistent with regard to sexual-activity history (e.g., previous sexual experience). Participants who underwent genital surgery showed less dyspareunia (P = 0.027) but more fear of injuries during intercourse (P = 0.019) than those whose genitals were left unaltered. CONCLUSIONS: SexQoL of persons with 46,XY DSD may be impaired. Differences in SexQoL between diagnostic subgroups, effect of corrective genital surgery, and the influence of gender assignment will have to be further investigated in future studies.

Long-term outcome and adjustment among patients with DSD born with testicular differentiation and masculinized external genital genitalia.

This report of long-term outcome and quality of life among 6 patients with DSD born with varying amounts of both testicular differentiation and masculinization of external genitalia, with 46,XY karyotypes among 4, attempts to assess numerous aspects. Assessment of 5 patients who were assigned female at birth and a sixth whose maleness was never questioned. Findings from the neonatal period are reported, focusing upon initial diagnosis, gender assignment, parental involvement, surgical and medical care, gender behaviors, psychological counseling and support, mental health and school experiences through adolescent years. Family, social, work, and physical, sexual and mental health status during adult life forms a basis for quality of life. Outcome vary from poor to good; influenced by parents' ability and commitment to support, the patients' personality and ability to accept their condition, quality of medical and surgical care, and family and friend support. Each of these factors could be improved by newer surgical techniques and more skilled psychological support. A basic underlying principal is the fact that in such complex cases, all factors cannot become ideal, especially those related to fertility potential and sexual responsiveness, while with support of family and loved ones, quality of life can be satisfying and productive.
