46,XY intersex individuals: phenotypic and etiologic classification, knowledge of condition, and satisfaction with knowledge in adulthood

Management of 46,XY Differences/Disorders of Sex Development (DSD) Throughout Life

Differences/disorders of sex development (DSD) are a heterogeneous group of congenital conditions that result in discordance between an individual's sex chromosomes, gonads, and/or anatomic sex. Advances in the clinical care of patients and families affected by 46,XY DSD have been achieved since publication of the original Consensus meeting in 2006. The aims of this paper are to review what is known about morbidity and mortality, diagnostic tools and timing, sex of rearing, endocrine and surgical treatment, fertility and sexual function, and quality of life in people with 46,XY DSD. The role for interdisciplinary health care teams, importance of establishing a molecular diagnosis, and need for research collaborations using patient registries to better understand long-term outcomes of specific medical and surgical interventions are acknowledged and accepted. Topics that require further study include prevalence and incidence, understanding morbidity and mortality as these relate to specific etiologies underlying 46,XY DSD, appropriate and optimal options for genitoplasty, long-term quality of life, sexual function, involvement with intimate partners, and optimizing fertility potential.

Disorders of sex development (DSD) web-based information: quality survey of DSD team websites

Objectives

Consumers rely on online health information, particularly for unusual conditions. Disorders of Sex Development (DSD) are complex with some aspects of care controversial. Accurate web-based DSD information is essential for decision-making, but the quality has not been rigorously evaluated. The purpose of the present study was to assess the quality of online health information related to DSD presented by 12 pediatric institutions comprising the NIH-sponsored DSD-Translational Research Network (DSD-TRN).

Methods

DSD-TRN sites identified team webpages, then we identified linked webpages. We also used each institution search engine to search common DSD terms. We assessed webpages using validated tools: the Simple Measure of Gobbledygook (SMOG) determined reading level, the Patient Education Materials Assessment Tool (PEMAT) evaluated content for understandability and actionability, and the DISCERN tool assessed treatment decision-making information (for hormone replacement and surgery). We developed a “Completeness” measure which assessed the presence of information on 25 DSD topics.

Results

The SMOG reading level of webpages was at or above high-school grade level. Mean (SD) PEMAT understandability score for Team Pages and Team Links was 68% (6%); on average these pages met less than 70% of the understandability criteria. Mean (SD) PEMAT actionability score was 23% (20%); few patient actions were identified. The DISCERN tool determined that the quality of information related to hormone treatment and to surgery was poor. Sites’ webpages covered 12–56% of the items on our Completeness measure.

Conclusions

Quality of DSD online content was poor, and would be improved by using a variety of strategies, such as simplifying word choice, using visual aids, highlighting actions patients can take and acknowledging areas of uncertainty. For complex conditions such as DSD, high-quality web-based information is essential to empower patients (and caregiver proxies), particularly when aspects of care are controversial.

Cognitive abilities in women with complete androgen insensitivity syndrome and women with gonadal dysgenesis

BACKGROUND

Many questions regarding the mechanisms behind sex differences in cognitive abilities are still unanswered. On a group level, men typically outperform women on certain spatial tasks, whereas women perform better on certain tests of memory and verbal ability. The prevailing theories concerning the biological predispositions for these and other differences in behaviour and brain function focus on early and prolonged exposure to sex hormones. There is, however, evidence of direct effects of sex chromosomes on sex-typical behaviour in other species.

OBJECTIVES

To study the influence of sex hormones and sex chromosomes on cognition in women with Complete androgen insensitivity (CAIS) and Gonadal dysgenesis (GD).

METHODS

Eighteen women with CAIS, 6 women with 46,XYGD, and 7 women with 46,XXGD were compared with age-matched male and female controls on tests of spatial and verbal abilities, memory functions, and emotion recognition.

RESULTS

Women with CAIS, XYGD, and XXGD performed similar to female controls on cognitive tasks. However, on a test of emotion recognition, women with XXGD outperformed the other groups, whereas women with CAIS and XYGD performed similar to male controls.

CONCLUSION

Our results support theories of androgen effects on cognitive abilities and suggest that factors related to sex chromosomes may influence emotion recognition. Implications of an atypical sex hormone situation and sex chromosome variation are discussed.

Development of Health-Related Quality of Life Instruments for Young Children With Disorders of Sex Development (DSD) and Their Parents

Objective

Research in disorders of sex development (DSD) is hindered by a lack of standardized measures sensitive to the experiences of affected children and families. We developed and evaluated parent proxy (children 2-6 years) and parent self-report (children ≤6 years) health-related quality of life (HRQoL) instruments for DSD.

Methods

Items were derived from focus groups and open-ended interviews. Clarity and comprehensiveness were assessed with cognitive interviews. Psychometric properties were examined in a field survey of 94 families.

Results

Measures demonstrated adequate to good psychometrics, including internal consistency, test-retest reliability, convergent validity, and ability to detect known-group differences. Parents reported greatest stress on Early Experiences , Surgery , and Future Concerns scales.

Conclusions

These instruments identify patients' and families' needs, monitor health and quality of life status, and can evaluate clinical interventions. Findings highlight the need for improved psychosocial support during the diagnostic period, better parent-provider communication, and shared decision-making. HRQoL measures are needed for older youth.

"It's Part of Me, Not All of Me": Young Women's Experiences of Receiving a Diagnosis Related to Diverse Sex Development

STUDY OBJECTIVE

To understand young women's experiences of receiving a diagnosis related to diverse sex development.

DESIGN

A qualitative narrative analysis of interviews.

SETTING

Karolinska University Hospital.

PARTICIPANTS

Nine women (aged 20-26 years) with complete androgen insensitivity syndrome, XY or XX gonadal dysgenesis.

INTERVENTIONS

Semistructured interviews.

MAIN OUTCOME MEASURES

A narrative approach was used to analyze the interviews. This involved identification of individual narratives of receiving the diagnosis, as well as identification of key issues that were common across interviews.

RESULTS

The analysis showed how participants' prediagnosis life experiences framed how medical information was perceived upon diagnosis. All participants had been informed about their condition before the study, but not all remembered the name of their diagnosis. Participants described positive characteristics of health professionals, such as being flexible and able to adapt to patients' individual needs. Clinicians' strategies, such as normalizing patients' experiences, were usually perceived as supportive, but were not always considered helpful. After the diagnosis, participants were worried about potential social, practical, and philosophical issues.

CONCLUSION

This research highlighted the importance of clinicians taking an exploratory and individualized approach to the sensitive process of disclosing a diagnosis related to diverse sex development to young adults. There are various strategies health professionals can use that might help young people to develop their knowledge about their condition: (1) repeating information to help the patient remember; (2) using language that is not too medicalized; and (3) communicating in a way that is meaningfully connected to patients' everyday lives.

Gender assignment in patients with disorder of sex development

PURPOSE OF REVIEW

To examine the sex assignment in patients with atypical external genitalia, a particularly challenging situation, especially when the genital appearance is not compatible with the sex chromosome.

RECENT FINDINGS

The most important factors that influence sex assignment include the definite diagnosis, genital appearance, surgical options, potential for fertility, risks of gonadal malignancy and, finally, the perception of the patients and their parents. Full disclosure and complete involvement of the parents in making decisions concerning gender assignment and/or genital surgery must be part of the basic medical care for children with disorder of sex development.

SUMMARY

Patients with disorder of sex development should receive long-term care provided by multidisciplinary teams in centers of excellence with ample experience in the management of this disorder.

Long-term outcome of male genital reconstruction in childhood

Hypospadias, epispadias with or without exstrophy, and disorders of sex development are among the most common anomalies of genitalia that occur during childhood. Considering the tremendous effect of genitourinary reconstruction on adult life, the evaluation of the long-term results of different techniques of genitoplasty in pediatrics is of the utmost importance. After reviewing the literature, the authors summarize the available long-term outcomes of genitoplasty in childhood, specifically focusing on the cosmetic, psychosocial, psychosexual and functional results, and emphasize that, contrary to the widely available data on early outcomes of genital reconstruction in the pediatric population, very few well described controlled studies have evaluated the long-term effect of genitoplasty in puberty and adulthood, in the sense that the surgeon should describe the peroperative findings in more detail and also be more structured in evaluating the postoperative result at follow-up visits. Finally, the authors conclude that more attention should be paid to the impact of these techniques on cosmetic aspects and psychosexual development in these patients after puberty, as they play a crucial role in their adult quality of life.

Review and management of 46,XY disorders of sex development

Disorders of sex development (DSD) among 46,XY individuals are rare and challenging conditions. Abnormalities of karyotype, gonadal formation, androgen synthesis, and androgen action are responsible for the multiple disorders that result in undervirilization during development. Phenotypic appearance and timing of presentation are quite variable. The focus of treatment has shifted from early gender assignment and corrective surgery to careful diagnosis, proper education of patients and their families, and individualized treatment by a multi-disciplinary team. The modern management of these patients is difficult and controversial. Conflicting data on long-term outcomes of these individuals have been reported in the literature. The various etiologies of 46,XY DSD, current approaches to diagnosis and treatment, and reported long-term results are reviewed.

Impaired puberty, fertility, and final stature in 45,X/46,XY mixed gonadal dysgenetic patients raised as boys

CONTEXT

Gender assignment followed by surgery and hormonal therapy is a difficult decision in the management of 45,X/46,XY patients with abnormal external genitalia at birth considering the paucity of studies evaluating pubertal development and fertility outcome, most notably for patients raised as boys.

OBJECTIVE

The purpose of this study was to describe the pubertal course of 20 45,X/46,XY patients born with ambiguous genitalia and raised as boys.

METHODS

This is a multicenter retrospective study.

RESULTS

Mean age at study was 25.6±2.4 years. Eighty-five percent of the patients presented a 'classical' mixed gonadal dysgenetic phenotype at birth. Puberty was initially spontaneous in all but three boys, although in six other patients, testosterone therapy was subsequently necessary for completion of puberty. Sixty-seven percent of the remaining patients presented signs of declined testicular function at the end of puberty (increased levels of FSH and low levels of testosterone and/or inhibin B). Moreover, an abnormal structure of the Y chromosome, known to alter fertility, was found in 10 out of 16 (63%) patients. Two patients developed testicular cancer. Half of the patients have adult penile length of <80 mm. Mean adult height is 156.9±2 cm, regardless of GH treatment.

CONCLUSIONS

In summary, 45,X/46,XY children born with ambiguous genitalia and raised as boys have an altered pubertal course and impaired fertility associated with adult short stature, which should, therefore, be taken into consideration for the management of these patients.

Testicular function and physical outcome in young adult males diagnosed with idiopathic 46 XY disorders of sex development during childhood

OBJECTIVE

There are few studies of outcome in male patients with undefined 46 XY disorder of sex development (DSD). We aimed to assess testicular function and clinical characteristics after puberty in men with idiopathic 46 XY DSD. Design We conducted a University Hospital-based observational follow-up study.

METHODS

Nineteen patients with severe hypospadias associated with other signs of defective virilization, such as microphallus, cryptorchidism, and/or bifid scrotum, who were initially managed during childhood between 1988 and 1994, were evaluated at a median age of 17.6 (16.3; 17.8) years. Outcome measures included clinical findings and serum testosterone, FSH, LH, and inhibin B concentrations.

RESULTS

Testicular function was normal in only five (26%) patients. Impaired testicular function was observed in 14 (74%) patients and was partial (n=6; 32%) or total (n=8; 42%), requiring testosterone treatment for the initial (n=2) or secondary (n=6) induction of puberty. Undescended testis (unilateral n=3, bilateral n=2) was found and surgically managed only in the 14 patients with testicular impairment. Testosterone treatment in early childhood greatly increased penis length in all patients, but persistent microphallus following surgical treatment was observed at the end of puberty in most patients, with no difference between patients with and without testicular dysfunction (penis length of 68 (60; 75) vs 65 (60; 65) mm; P=0.42). Half the patients presented an adult height more than 5 cm below their target height.

CONCLUSION

Men diagnosed with idiopathic 46 XY DSD during childhood are at high risk of testicular insufficiency and persistent micropenis, and this should be taken into account during the follow-up.

Regional variations in the management of testicular or ovotesticular disorders of sex development

Disorders of sex development arise in parts of the world with different socio-economic and cultural characteristics. We wished to determine the regional variations in the management of these conditions. A questionnaire was e-mailed to the 650 members of the European Society for Paediatric Endocrinology (ESPE), an international society with a mainly European membership but which also includes professionals from other continents. Results were subjected to statistical analysis. A total of 62 answers were received, a satisfactory rate given that not all members are involved in this issue. Results show statistically significant regional differences for available diagnostic resources, age of the patient at gender assignment, parameters considered important for gender assignment, and timing of discussion of various issues with parents and patient. The regional variations exist not only between different continents, as already demonstrated by others, but also between Northern, Latin and Eastern European countries. This suggests that 'one-fits-all' guidelines for management are not appropriate.

Evaluation of terminology used to describe disorders of sex development

OBJECTIVE

The terminology used to describe abnormalities of sex determination and sex differentiation was revised in 2006. It was anticipated that new terms, such as 'disorders of sex development' (DSD), would improve communication between health professionals, aid parental understanding and be acceptable to affected individuals. The purpose of this study was to evaluate the success of the new terminology.

SUBJECTS AND METHODS

Using a questionnaire, we evaluated the acceptance of these new terms by parents of children with a DSD (n = 19), health professionals (n = 15) and parents of unaffected children (n = 25).

RESULTS

Comparing the term 'DSD' to 'intersex', overall 86.4% of participants preferred the term 'DSD', and parents of a child with a DSD had an even higher preference (94.7%). Parents of an affected child considered the new term to improve their understanding of their child's condition (83.3%), and to aid explanation by parent to affected child (82.4%) and to wider family and friends (84.2%). Health professionals preferred the genotype-based terms, whereas parents considered these terms confusing. Overall, 59.3% of participants agreed DSD was an acceptable new term.

CONCLUSIONS

There was broad support for the new terminology by parents and health professionals. The description 'disorder of sex development' may be helpful to parents at the time when it is not possible to assign gender, after which aetiologically based diagnoses should be used where possible.

Clinical evaluation study of the German network of disorders of sex development (DSD)/intersexuality: study design, description of the study population, and data quality

BACKGROUND

The German Network of Disorders of Sex Development (DSD)/Intersexuality carried out a large scale clinical evaluation study on quality of life, gender identity, treatment satisfaction, coping, and problems associated with diagnoses and therapies in individuals with disorders of sex development (DSD). DSD are a heterogeneous group of various genetic disorders of sex determination or sex differentiation, all of which are rare conditions. In about half of all cases the molecular genetic diagnosis is unknown and diagnosis rests on clinical features.

METHODS AND DESIGN

The multi-centre clinical evaluation study includes short-term follow-up in some and cross-sectional assessments in all age and diagnostic groups fitting the criteria of DSD. Recruitment was from January 2005 until December 2007 in whole Germany and, additionally, in 2007 in Austria and German-speaking Switzerland. The study consists of a psychosocial inquiry for children, adolescents and their parents, and adults with standardized instruments and the collection of DSD-specific medical data by the attending physician. The main goal was the description of clinical outcomes and the health-care situation of individuals with DSD using a broad generic definition of DSD including all conditions with a mismatch of chromosomal, gonadal and phenotypical sex. 439 children and adolescents, their parents and adults with DSD participated.

DISCUSSION

The clinical evaluation study represents the most comprehensive study in this clinical field. The paper discusses the study protocol, the data management and data quality as well as the classification used, and it describes the study population. Given the lack of large datasets in rare conditions such as DSD and often biased results from small scale clinical case series, the study aims to generate concrete hypotheses for evidence-based guidelines, which should be tested in further studies.

Care of women with XY karyotype: a clinical practice guideline

OBJECTIVE

To provide an evidence-based guideline for professionals working with XY women.

DESIGN

Review including patient cases from a Danish fertility clinic.

SETTING

University-associated scientific unit and fertility clinic.

PATIENT(S)

Three selected cases.

INTERVENTION(S)

None.

MAIN OUTCOME MEASURE(S)

Evaluation of etiology, diagnosis, treatment, and associated disorders in XY women.

RESULT(S)

Many gene mutations can cause abnormal fetal development leading to androgen insensitivity syndrome or gonadal dysgenesis disorders. Females with these disorders have an XY karyotype but look like girls. They are mostly diagnosed at puberty, and the condition will often lead to serious psychological problems. Increased risk of malignancies and problems with pregnancy and infertility are other aspects that should be considered. This guideline will aid doctors in caring for XY females.

CONCLUSION(S)

A precise diagnosis is important, because the treatment possibilities (e.g., use of allogenic oocytes) depend on the subgroup to which the XY female belongs.

Disorders of sexual differentiation in the adolescent

Disorders of sexual differentiation (DSDs) presenting during adolescence are discussed, and molecular explanations are given for some. DSD conditions are often discovered during early adolescence, an age well known to predispose to high risk for adjustment problems. Presentation may be with lack of or minimal pubertal development, lack of menarche, vaginal, uterine, or breast agenesis and inappropriate sexual development such as virilization in females or feminization (gynecomastia) in males. Most such disorders require life-long therapy, with many of the medical, surgical and psychological aspects of management being accentuated during adolescence. Regardless of the age at presentation, all require skillful management to promote normal health and well-being. This care ideally involves specialists in endocrinology and medical therapy, psychology and, if required, surgery. A brief discussion of the needs of the adolescent with DSDs is presented.

Intersexuality and alternative gender categories in non-Western cultures

BACKGROUND

In the Western world, it is widely accepted as natural - and seen almost as a law of nature - that mankind is divided into two sexes or genders - males and females. In many cultures and societies, however, more than two sex and/or gender categories are recognized, which in some instances refer to the biological sex and in others to gender roles and social status.

AIMS

To give an intercultural comparison of various ways of dealing with gender variance.

METHODS

In the following paper, we review the anthropological literature during the last 100 years describing individuals who live neither as men nor women in various non-Western cultures.

RESULTS

Only rarely, these individuals suffer from disorders of sex development in the modern medical or biological definition: in many if not all societies there have been individuals who are not covered by the gender category of male and female.

CONCLUSION

There thus appears to be a cultural need for people with a special neither-male-nor-female status, which might be classified as 'gender variance'.

The biology of human psychosexual differentiation

Most attempts to identify biological underpinnings of gender identity and sexual orientation in humans have investigated effects of sex steroids, so pivotal in the differentiation of the genitalia, showing strong parallels between animals and the human. The information on humans is derived from the so-called 'experiments of nature', clinical entities with a lesser-than-normal androgen exposure in XY subjects and a higher than normal androgen exposure in XX subjects. Prenatal androgenization appears to predispose to a male gender identity development, but apparently not decisively since 40-50% of 46,XY intersexed children with a history of prenatal androgen exposure do not develop a male gender identity. Obviously, male-to-female transsexuals, with a normal androgen exposure prenatally (there is no serious evidence to the contrary) develop a female gender identity, through unknown biological mechanisms apparently overriding the effects of prenatal androgens. The latest studies in 46, XX subjects exposed to prenatal androgens show that prenatal androgenization of 46,XX fetuses leads to marked masculinization of later gender-related behavior but does not lead to gender confusion/dysphoria. The example of female-to-male transsexuals, without evidence of prenatal androgen exposure, indicates that a male gender identity can develop without a significant androgen stimulus. So we are far away from any comprehensive understanding of hormonal imprinting on gender identity formation. Brain studies in homosexuals have not held up in replication studies or are in need of replication in transsexuals. Genetic studies and the fraternal birth order hypothesis provide indications of familial clustering of homosexuality but in many homosexuals these genetic patterns cannot be identified. The biological explanations advanced for the birth order hypothesis lack any experimental support.

Impaired sexual activity in male adults with partial androgen insensitivity

CONTEXT

Choosing the sex of rearing of an XY neonate with a major sexual ambiguity and a mutated androgen receptor remains one of the more difficult questions of neonatal endocrinology. A direct consequence of this choice is the accomplishment of sexual function in adulthood. There is very limited knowledge of the sexual performance of patients with partial androgen insensitivity syndrome.

OBJECTIVE

The objective of this study is to describe physical acts of sexuality in partial androgen insensitivity syndrome patients reared as males.

DESIGN

We were able to obtain factual information regarding the sexual activity of 15 adult patients who had been reared as males and followed at our institution since birth. We evaluated their sexual performance using two validated questionnaires (Golombok-Rust Inventory of Sexual Satisfaction and International Index of Erectile Dysfunction).

RESULTS

We documented a major impairment of all parameters of sexual activity.

CONCLUSION

This long-term insight into the consequences of male sex assignment will have to be balanced by a study of the consequences of female sex assignment.

Sexualmedizinische Aspekte bei Intersexsyndromen

Disorders of somatosexual development that lead to ambiguous genitalia occur in one from 3,000-5,000 newborns. Parents and health care professionals are confronted with a number of crucial questions: to what sex should the child be assigned, what is the appropriate treatment in terms of hormonal and surgical interventions, when and how should these take place, and what impact do they have on the development of gender identity (GI), psychosexual well-being and fertility? This paper reviews the etiology, treatment and outcome in terms of GI and sexual health for the following syndromes: congenital adrenal hyperplasia (CAH), complete and partial androgen insensitivity (cAIS, pAIS), and pure and mixed gonadal dysgenesis (pGD, mGD). Emphasis is focussed on the current discussion involving the timing and extent of genital surgery. Finally, a procedure is introduced that covers the sexual-medical needs of patients, parents and health care professionals.

Medical and psychosexual outcome in women affected by complete gonadal dysgenesis

BACKGROUND

Prenatal exposure to testicular hormones influences the development of brain structures and behavior in many non-human mammalian species. Less understood is the role of possessing a Y chromosome, independent of testicular hormones, on psychosexual differentiation.

HYPOTHESIS

Phenotypic women affected by complete gonadal dysgenesis possess a 46,XY chromosome complement and streak gonads. This population is suitable to test the influence of an absence of androgens and Müllerian inhibiting substance on psychosexual development in genetic males.

PATIENTS

Three 46,XY women diagnosed with complete gonadal dysgenesis participated.

METHODS

Psychosexual development, medical outcome and knowledge of medical condition were assessed with a written questionnaire and a physical examination.

RESULTS

All participants were healthy, compliant with their hormone therapy, and exhibited female-typical psychosexual development. However, participants were poorly informed about their condition and the fertility treatment options available to them.

CONCLUSIONS

These data indicate no obvious role for genes on the Y chromosome, outside of its pseudoautosomal region and SRY, on psychosexual differentiation in genetic males who do not produce testicular hormones. Greater efforts need to be made to educate affected women about their pregnancy options.

Long-Term Surgical Results and Patient Satisfaction With Male Pseudohermaphroditism or True Hermaphroditism: A Cohort of 63 Patients

PURPOSE

To improve treatment policy, we retrospectively evaluated the results of early corrective genital surgery in 63 sexually ambiguous patients 14 to 38 years old.

MATERIALS AND METHODS

We analyzed all records classified under male pseudohermaphroditism and true hermaphroditism. Anatomical and functional results and data on self-reported satisfaction were recorded by the managing physician at the last routine followup visit.

RESULTS

A total of 38 patients were raised female and 25 were raised male. Basal procedures for external genital reconstruction were initiated shortly after birth, when gender was assigned. Complementary surgical procedures were usually required later. In both sexes there was a significant negative correlation between the number of basal, but not complementary, procedures required and year of birth, due to the adoption of 1-stage procedures in the early 1980s. Most patients with gonadal dysgenesis were raised as females and menstruated under treatment but breast development was abnormal in 30%. Spontaneous puberty was observed in true hermaphrodites raised as either sex. In females with partial androgen insensitivity the main problem was shortness of the vagina. Amenorrhea and infertility often led to transient distress. In males results were poor due to intractable micropenis and minimal virilization. Results were good in 5alpha-reductase deficiency.

CONCLUSIONS

Results of intersex surgery have clearly improved with time, and apart from a patient with 5alpha-reductase deficiency who underwent a successful sex change, no patient expressed dissatisfaction with sex of rearing. However, in the absence of an in-depth psychological survey, these optimistic conclusions are valid only in the settings of our study.

Current views on evaluation, management, and gender assignment of the intersex infant

In recent years, traditional views regarding the management of infants with intersex conditions have been challenged. Some of these patients have gender dysphoria and gender conversion, although most adults with intersex consider themselves to be either male or female. Hormonal and genetic factors may have a more important role in gender identity and sexual satisfaction than previously recognized, whereas the importance of phallus size to male gender identity and sexual satisfaction may have been overestimated. The impact of androgen imprinting on the developing brain is uncertain, but it is likely to be significant. The issue of genital surgery in infancy is controversial, although many adult patients concur that infancy is the best time for such procedures. Several reports indicate that the functional outcomes of genital surgery are poor, although more recently developed surgical techniques may achieve better results. Good communication between physicians, patients, and families regarding intersex conditions is paramount. We review current understanding of the evaluation and management of intersex conditions.

Does Surgical Genitoplasty Affect Gender Identity in the Intersex Infant?

There is no clear-cut answer to the question of whether surgical genitoplasty affects gender identity in the intersex infant. The debate centres around which is more important for the development of gender identity: the biological sex of a child or the sex in which a child is reared. We believe that the surgical achievement of a phenotype concordant with the sex of rearing is a tremendous help to the parents of an intersex infant. We do not consider that the 'neutral' upbringing of a child with ambiguous genitalia is a feasible option, first because of the parents' distress which prevents them from raising their child normally and second because in most cultures around the world gender variants are not treated as equals. A neutral upbringing may induce psychosocial consequences that are more pernicious than carefully considered neonatal sex attribution and concordant surgical genitoplasty.

Intersexed states: diagnosis and management

Traditional guidelines for the care of intersexed patients have been questioned by dissatisfied adult intersexed patients. The controversy surrounding this issue comes from a handful of highly publicized intersexed cases with poor outcomes, representing a minority of the intersexed population, which serve as an appropriate call to reassess this difficult issue. Re-evaluation of management strategies must acknowledge the complaints of those who oppose the traditional management paradigm and address scientific and surgical advancements and the roles they should play. This article reviews these issues, attempts to formulate a contemporary approach, and acknowledges the gaps that remain in our knowledge.

Gender dysphoria and gender change in androgen insensitivity or micropenis

This review article answers three questions relevant to the medical management and care of individuals born with complete androgen insensitivity syndrome (CAIS), partial androgen insensitivity syndrome (PAIS), or a micropenis: (1) Do any of these individuals reassign themselves from their initial gender assignment? (2) Do more reassign than the ones who do not? (3) Is there evidence of gender dysphoria in those who do not self-initiate reassignment? Reviewed were all articles on CAIS, PAIS, and micropenis cited in K. J. Zucker (1999) plus articles published through 2004. There were no documented cases of gender change in individuals with CAIS (N= 156 females) or micropenis (N= 89: 79 males, 10 females). Nine (9.1%) out of 99 individuals with PAIS changed gender. Thus, self-initiated gender reassignment was rare. Gender dysphoria also appears to be a rare occurrence. The best predictor of adult gender identity in CAIS, PAIS, and micropenis is initial gender assignment.

Sex, gender, and identity over the years: a changing perspective

This article attempts to put changing terms, emphases, and views on the interrelated, but separate, concepts of sex, gender, and identity into perspective. Often, these facets of a person's life are intermingled and confused. To understand individuals whose lives are touched by any aspect of sexuality that is of interest to the medical community, knowledge of how these terms have developed and changed over the years seems of particular value. The article also tries to show the relevance of certain concepts in dealing with the specific issues of intersex. Here, medical management and ethical thinking about dealing with such conditions also have undergone change. It is probable that the terms and treatment modalities that are associated with sex- and gender-related conditions will continue to evolve as we learn more about them.

ATTITUDES OF ADULT 46,XY INTERSEX PERSONS TO CLINICAL MANAGEMENT POLICIES

PURPOSE

We surveyed a clinic sample of adult 46,XY intersex patients regarding attitudes to clinical management policies.

MATERIALS AND METHODS

All adult former patients of 1 pediatric endocrine clinic in the eastern United States whose addresses could be obtained and who consented to participation were surveyed by a comprehensive written followup questionnaire. Three questions on attitudes concerning the desirability of a third gender category and the age at which genital surgery should be done were presented in the context of ratings of satisfaction with gender, genital status and sexual functioning.

RESULTS

A total of 72 English speaking patients with 46,XY, including 32 men and 40 women 18 to 60 years old, completed the questionnaire. The majority of respondents stated that they were mainly satisfied with being the assigned gender, did not have a time in life when they felt unsure about gender, did not agree to a third gender policy, did not think that the genitals looked unusual (although the majority of men rated their penis as too small), were somewhat or mainly satisfied with sexual functioning, did not agree that corrective genital surgery should be postponed to adulthood and stated that their genital surgeries should have been performed before adulthood, although there were some significant and important differences among subgroups.

CONCLUSIONS

The majority of adult patients with intersexuality appeared to be satisfied with gender and genital status, and did not support major changes in the prevailing policy. However, a significant minority was dissatisfied and endorsed policy changes.

A late sex reassignment in 5-alpha reductase deficiency: case report

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.

Human sex differentiation and its abnormalities

The purpose of this chapter is to review the presentation and management of patients affected by conditions of abnormal sex differentiation. First, the processes of normal sex differentiation are covered, followed by an overview of the various syndromes of abnormal sex differentiation, or intersex conditions, that can occur. These disorders are presented according to the following categories: patients who possess a 46,XX chromosome complement, those who possess a 46,XY chromosome complement, and individuals who present with an atypical sex chromosome complement (i.e. 45,XO or 45,X0/46,XY mosaicism). A description of the medical, surgical and psychological treatment options for people affected by various intersex conditions and reared as females are included. Practice points, based on research studies when available, are dispersed throughout the chapter. Additionally, information pertaining to relevant Internet websites and patient support groups are provided, so that medical staff can educate their patients about the availability of these resources.

Ambiguous genitalia with perineoscrotal hypospadias in 46,XY individuals: long-term medical, surgical, and psychosexual outcome

OBJECTIVES

To identify and study adults (21 years or older) who have a 46,XY karyotype and presented as infants or children with genital ambiguity, including a small phallus and perineoscrotal hypospadias, reared male or female.

METHODS

Participants were classified according to the cause underlying their intersex condition based on review of medical and surgical records. Long-term medical and surgical outcome was assessed with a written questionnaire and physical examination. Long-term psychosexual development was assessed with a written questionnaire and semistructured interview.

RESULTS

Thirty-nine (72%) of 54 eligible patients participated. The cause underlying genital ambiguity of participants included partial androgen insensitivity syndrome (n = 14; 5 men and 9 women), partial gonadal dysgenesis (n = 11; 7 men and 4 women), and other intersex conditions. Men had significantly more genital surgeries (mean: 5.8) than women (mean: 2.1), and physician-rated cosmetic appearance of the genitalia was significantly worse for men than for women. The majority of participants were satisfied with their body image, and men and women did not differ on this measure. Most men (90%) and women (83%) had sexual experience with a partner. Men and women did not differ in their satisfaction with their sexual function. The majority of participants were exclusively heterosexual, and men considered themselves to be masculine and women considered themselves to be feminine. Finally, 23% of participants (5 men and 4 women) were dissatisfied with their sex of rearing determined by their parents and physicians.

CONCLUSIONS

Either male or female sex of rearing can lead to successful long-term outcome for the majority of cases of severe genital ambiguity in 46,XY individuals. We discuss factors that should be considered by parents and physicians when deciding on a sex of rearing for such infants.
