How common is intersex? a response to Anne Fausto-Sterling

Why do ‘we’ perform surgery on newborn intersexed children?

Few parents-to-be consider that their child may be born with ambiguous sex. Still, parents of a newborn child with ambiguous sex are expected to make a far-reaching decision for the child: should the child be operated upon so that it has either female or male genitals? The aim of this article is to examine, phenomenologically, why parents decide to have their children undergo genital surgery when it is not necessary for the child’s physiological functions. Drawing on phenomenological work by Maurice Merleau-Ponty, Simone de Beauvoir and Sara Ahmed, we examine parents’ frustration when their child’s sex is ambiguous and their experiences of the practice of medical sex assignment. We also examine parental identity work when the child has been assigned a sex and the interaction between parents and medical professionals when parents make decisions regarding surgery on their child. Furthermore, we provide a critical perspective on the surgical practice.

Disorders of sexual development

Disorders of sex development are medical conditions in which the development of chromosomal, gonadal, or anatomic sex varies from normal and may be incongruent with each other. This article primarily addresses the medical conditions where infants may be born with ambiguous genitalia leading to decisions with regard to gender assignment. The approach to investigations and diagnosis in the newborn period will be stressed within an interprofessional team. Policies with regard to surgery have developed, with techniques evolving and data emerging from long-term outcome studies. Current medical and surgical management are reviewed. Finally, a developmental approach to disclosure is presented.

Congenital adrenal hyperplasia: an endocrine disorder with neonatal onset

Congenital adrenal hyperplasia (CAH) is a lifelong endocrine disorder that manifests acutely in the neonatal period. In the affected female newborn, CAH is associated with variable degrees of genital ambiguity that are extremely distressing to the new parents. The manner in which health care professionals react in the delivery room, newborn nursery, or neonatal intensive care unit in the early postnatal period is important. Insensitive or inappropriate statements cannot only be hurtful to families but are long remembered and can shape the attitude formed by parents toward their newborn.

Unique challenges of transgender aging: implications from the literature

Transgender elders are both underserved and understudied. Neither the etiology nor prevalence of transgender is well understood. Because sex, gender, and sexuality are at the very core of individual identity, it is difficult to dislodge one's ideas and feelings about them. Unlike biological sex and sexual orientation, gender has several aspects: gender identity, gender expression, and gender classification. A discussion of the terminology of transgender is presented, and the issues facing aging transgender individuals are identified. Although the challenges of adequate healthcare, social support, and legal obstacles are faced by many elderly individuals, the way they are presented and managed are unique to this often invisible group.

Management of disorders of sex development

Disorders of sex development comprise a group of diagnoses that represent significant and controversial management difficulties, such as those relating to gender assignment, genital surgery and risk of gonadal malignancy or future gender dysphoria. These issues arise on the background of a diagnosis that is often fraught with psychological trauma for patients and their families. There have been many changes in the medical approach to management in recent years; however, more research is required. This should focus on achieving accurate diagnosis in the first case, and on following outcomes to advise best practice. Finally, rational dialogue between multidisciplinary care providers, ethicists and patients and their families will only lead to improved care for these children.

Intimate partner violence among sexual minorities in Japan: exploring perceptions and experiences

Using qualitative interviews (n = 39) and participant observation (n = 54), this study documents perceptions and experiences of violence between lesbian, gay, bisexual, transgender, and intersex intimate partners in Japan, thereby providing exploratory, formative data on a previously unexamined issue. Results indicate that intimate partner violence (IPV) is experienced physically, sexually, and psychologically in all sexual minority groups. Participants perceived the violence to be: a) very similar to heterosexual IPV against women; b) more likely perpetrated and experienced by lesbians, bisexual women, and transgender persons compared to gay and bisexual men and intersex persons; c) the cause of several negative physical and mental health outcomes; and d) largely unrecognized in both sexual minority communities and broader Japanese society.

Perfil clínico de 62 casos de distúrbios da diferenciação sexual

OBJETIVO: Descrever o perfil clínico dos casos de distúrbios da diferenciação sexual em acompanhamento no Instituto Estadual de Diabetes e Endocrinologia Luiz Capriglione, no Rio de Janeiro, nos últimos cinco anos. MÉTODOS: Revisão dos prontuários dos pacientes, com o diagnóstico de genitália ambígua em acompanhamento nos últimos cinco anos, segundo os critérios clínicos descritos por Danish, em 1982. O registro mais antigo foi feito em 1981 e o mais recente de junho de 2006. RESULTADOS: Foram encontrados 62 casos de genitália ambígua: 26 com registro do sexo feminino e 36 com registro do sexo masculino. O diagnóstico mais freqüente foi o de hiperplasia congênita de supra-renal (33,9%), seguido de quadros sindrômicos (14,5%) e disgenesias gonadais (9,7%). A média de idade ao diagnóstico foi de 7,2 anos (de zero a 42 anos). CONCLUSÕES: A ambigüidade genital não é uma doença específica, mas um conjunto de alterações que direcionam o clínico a buscar diagnósticos específicos. A freqüência dessa afecção depende dos critérios diagnósticos utilizados. A adoção de critérios amplos aumenta a chance de detecção precoce do quadro bem como de cuidado adequado a crianças com distúrbios da diferenciação sexual.

Suicidality and self-harm among sexual minorities in Japan

In this study, I used ethnographic methods to examine suicidality and nonsuicidal self-harm among gay, lesbian, bisexual, and transgender persons in Japan. Participants (N = 84) indicated that suicidality and self-harm are serious problems among sexual minorities and tend to be driven by (a) a homophobic/transphobic environment and the negative consequences of sexual minorities either disclosing their true selves or remaining hidden and silent within such an environment; (b) various antecedents to poor mental health; and (c) factors not directly related to being a sexual minority, particularly unemployment and debt in the context of a protracted national economic decline in Japan prior to the study period of 2003--2004. Participants also perceived a potentially higher risk for suicidality and self-harm among sexual minority adolescents and persons in their early 20s; those who work in the entertainment, bar, or sex industries; and survivors of violence perpetrated by intimate partners or family members.

Disorders of sex development: hormonal management in adolescence

Hormonal treatment represents the principal aspect of clinical management of people with disorders of sex development (DSD) from adolescence onwards. In fact, individuals with DSD may require sex steroid replacement to induce secondary sex characteristics, to optimize bone mass accrual, and to promote physical and social well-being. Testosterone is the main hormone for treatment in males and estrogens in females. The optimal regimens for sex steroid substitutive therapy in subjects with DSD should be better defined in multi-center prospective studies. Bone health remains a crucial aspect in the management of these persons, but few sound data are available to guide clinical practice.

ORIGINAL RESEARCH–INTERSEX AND GENDER IDENTITY DISORDERS: Male Gender Identity in an XX Individual with Congenital Adrenal Hyperplasia

INTRODUCTION

In spite of significant changes in the management policies of intersexuality, clinical evidence show that not all pubertal or adult individuals live according to the assigned sex during infancy.

AIM

The purpose of this study was to analyze the clinical management of an individual diagnosed as a female pseudohermaphrodite with congenital adrenal hyperplasia (CAH) simple virilizing form four decades ago but who currently lives as a monogamous heterosexual male.

METHODS

We studied the clinical files spanning from 1965 to 1991 of an intersex individual. In addition, we conducted a magnetic resonance imaging (MRI) study of the abdominoplevic cavity and a series of interviews using the oral history method.

MAIN OUTCOME MEASURES

Our analysis is based on the clinical evidence that led to the CAH diagnosis in the 1960s in light of recent clinical testing to confirm such diagnosis.

RESULTS

Analysis of reported values for 17-ketosteroids, 17-hydroxycorticosteroids, from 24-hour urine samples during an 8-year period showed poor adrenal suppression in spite of adherence to treatment. A recent MRI study confirmed the presence of hyperplastic adrenal glands as well as the presence of a prepubertal uterus. Semistructured interviews with the individual confirmed a life history consistent with a male gender identity.

CONCLUSIONS

Although the American Academy of Pediatrics recommends that XX intersex individuals with CAH should be assigned to the female sex, this practice harms some individuals as they may self-identify as males. In the absence of comorbid psychiatric factors, the discrepancy between infant sex assignment and gender identity later in life underlines the need for a reexamination of current standards of care for individuals diagnosed with CAH.

Disorders of sex development

PURPOSE OF REVIEW

The current management of patients with intersex, now designated as disorders of sex development, is presented in the context of updated etiological and outcome data, refined surgical procedures and the need for a multidisciplinary approach.

RECENT FINDINGS

The recently published consensus statement, the primary publication cited herein, includes known genetic causes of disorders of sex development, and provides a perspective for clinical evaluation, and medical, surgical and psychological management. The importance of fetal hormone exposure, genital development, gonadal differentiation and potential of fertility, full disclosure and parental involvement in decisions is crucial. All need a sex assignment; recommendations should be based upon what is judged to be the most likely adult gender identity, diagnosis, genital appearance and surgical options, fertility, cultural pressures, family dynamics and social circumstance, with deference given to psychosocial factors when the outcome is unpredictable. Surgery is discouraged for mild genital variations, but surgery during infancy is recommended for those with major genital ambiguity.

SUMMARY

Even with greater understanding of the genetic causes of disorders of sex development, the complex management of these patients must be individualized, considering all aspects, informing as age-appropriate the parents and patient. Further etiology and outcome studies are needed.

As novas definições e classificações dos estados intersexuais: o que o Consenso de Chicago contribui para o estado da arte?

As anomalias da diferenciação sexual têm-se constituído em um formidável desafio quanto ao diagnóstico e à conduta, colocando o paciente, os familiares e os profissionais da equipe de saúde na difícil situação de definir a melhor opção quanto ao gênero de criação. Uma terminologia confusa e estigmatizante tem sido adotada e, nesse sentido, o Consenso de Chicago propõe várias modificações no sentido de minimizar os desconfortos graças a uma terminologia que nem sempre auxilia na solução de problemas. Os autores fazem uma análise crítica da classificação sugerida pelo Consenso, levantando a questão de que, na nova classificação, também não se resolvem certos problemas terminológicos e continua a se criar algum grau de estigmatização. Em primeiro lugar, a sugestão de se incluir o cariótipo no nome da doença supõe, erroneamente, que os pacientes não tenham conhecimento do que significa ser 46,XY ou 46,XX. Uma criança criada no sexo feminino com uma anomalia da diferenciação sexual (ADS) 46,XY não vai entender porque está no sexo feminino se seu cariótipo é "masculino". A substituição do termo hermafroditismo verdadeiro por ADS ovotesticular está longe de resolver o problema de estigmatização causado por "hermafroditismo". O termo ovotesticular é claramente entendido como uma fusão entre ovário e testículo e não será aceito com "naturalidade". Se, por um lado, é muito satisfatório que a questão da nomenclatura seja discutida, por outro lado devemos escolher termos alternativos que sejam realmente neutros e não tragam, em si, a conotação de um sexo que pode não condizer com o escolhido para aquele paciente em particular. Um ponto em que todos concordamos é que a substituição de intersexo por anomalia da diferenciação sexual (ADS) ou, disorder of sex development (DSD), na língua inglesa, cai muito melhor e não dá a conotação de um "sexo intermediário" como o nome antigo proporcionava.

Intersexualität

Different forms of intersexuality (Disorders of Sex Development, DSD) are described (congenital adrenal hyperplasia, androgen insensitivity, disorders of androgen biosynthesis, gonadal dysgenesis). Treatment interventions for individuals with ambiguous genitalia and untypical sex development are discussed with respect to medical and psychosocial aspects considering the consensus paper on the management of subjects with intersexuality. The role of gender identity, gender role and sexual orientation are presented as well as problems of disclosure and gender change. Further research is needed to evaluate the optimal treatment procedures.

17beta-hydroxysteroid dehydrogenase-3 deficiency: a rare endocrine cause of male-to-female sex reversal

Deficiency of 17beta-hydroxysteroid dehydrogenase type 3 (17beta-HSD3), due to mutations in the gene encoding the enzyme, results in a rare autosomal recessive form of male-to-female sex reversal. Mutated genes encode an abnormal enzyme with absent or reduced ability to convert Delta4-androstenedione to testosterone in the testis. Affected individuals are genetically males who developed internal male Wolffian structures but female external genitalia. Such individuals are usually raised as females and diagnosis is made at puberty, when they show virilization. Correct diagnosis is mandatory to optimize treatment and follow-up. In the present paper we report the clinical history, endocrine evaluation and molecular genetics of a prepubertal girl affected by 17beta-HSD3 deficiency, in whom an erroneous diagnosis of androgen insensitivity syndrome was made. The clinical, endocrine and genetic features of 17beta-HSD3 deficiency are also reviewed.

Epidemiology and initial management of ambiguous genitalia at birth in Germany

BACKGROUND

In this epidemiological study, we sought to capture the incidence of ambiguous genitalia in neonates and to describe initial management strategies.

METHODS

We used the registry for rare diseases in pediatrics in Germany to ascertain cases and asked reporting institutions for information on phenotype, laboratory tests, imaging results, diagnosis, initial management and sex assignment.

RESULTS

We identified 80 cases within a 2-year study period and calculated an incidence of 2 per 10,000 births with ambiguous genitalia per year in Germany. Prevalence was higher in infants from non-German family background. In more than 50% of all infants a definite diagnosis was lacking even at the age of 6 months. In those cases where the etiology was confirmed, the most common diagnosis was congenital adrenal hyperplasia, followed by androgen insensitivity syndrome and mixed gonadal dysgenesis. Associated malformations were very common, affecting 37.5% of all infants. Sex assignment was female in 46,XY infants with predominately female phenotype and all 46,XX infants. Early surgery was performed in many cases irrespective whether a definite diagnosis had been established or not. Integrated psychosocial care was the exception rather than the rule.

CONCLUSIONS

Classification and management of ambiguous genitalia at birth remain a challenge for all professionals involved. National and international registries may help to provide a better understanding of the incidence and clinical course of such disorders.

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.

Intersex embodiment: when health care means maintaining binary sexes

The treatments carried out with intersex children for the purpose of helping them live in a normatively gendered world have raised increasing levels of controversy in the past decade. This paper outlines key debates that are taking place highlighting the relevance of critical approaches to evidence. It points to the value of working across disciplines and epistemological frameworks in order to fundamentally re-think existing clinical practice in terms of ethical concerns and in terms of the reported experiences of intersex people.

Cosmetic and anatomic outcomes after feminizing surgery for ambiguous genitalia

BACKGROUND

Reports on anatomic and cosmetic outcomes after genital surgery for children with ambiguous genitalia are mixed, with recent reports using standardized assessments suggesting poor outcomes and that multiple operations may be required.

METHODS

All children with ambiguous genitalia and who had feminizing surgery at the Royal Children's Hospital in Melbourne, Australia, were identified. Standardized genital assessment was undertaken at their clinical review after informed consent. Underlying diagnosis, number and type of procedures performed, and the expertise of the surgeon were recorded from their medical notes.

RESULTS

Of 32 patients examined aged 13 to 33 years, 47% had congenital adrenal hyperplasia. Ten patients had initial surgery performed elsewhere. Overall, there were good anatomic and cosmetic outcomes for those initially treated at our institute by a specialized surgeon, although some required additional intervention in adolescence or adulthood. Initial surgery before or after 2 years of age did not significantly affect outcomes. Those patients who had only 1 operation (by a surgeon with special interest in intersex) had better cosmetic and anatomic outcomes than those patients who had multiple operations.

CONCLUSIONS

Cosmetic and anatomic outcomes of surgery for ambiguous genitalia were generally good when undertaken by pediatric surgeons with specific expertise in intersex surgery.

Hormonal therapies for individuals with intersex conditions: protocol for use

Hormonal therapy forms part of the treatment of every intersex condition. For some conditions, such as salt-wasting congenital adrenal hyperplasia, hormonal replacement therapy is life saving because hormones necessary for survival (cortisol and aldosterone) are replaced. In contrast, other hormones such as androgens or mineralocorticoids are secreted in excessive amounts in congenital adrenal hyperplasia due to an enzyme imbalance, and the role of hormonal therapy is to suppress the unwanted hormone excess by exerting negative feedback. For patients with one of the many causes of hypogonadism, sex hormone replacement therapy may be prescribed to stimulate sexual development: growth of a hypoplastic penis in a young boy, pubertal changes (male or female), psychosexual development, and adult sexual behavior. It has equally important and highly beneficial effects on bone mineral density. Hormonal therapy is also used to treat the unborn child. For the last 20 years, prenatal dexamethasone treatment administered to the pregnant woman has been used to prevent the development of ambiguous genitalia in females with 21-hydroxylase deficiency. Outcome studies show this treatment to be well tolerated and, in general, efficacious. Intersex conditions are, however, difficult to treat because they may intrinsically perturb complex aspects of the person's gender identity, gender-role behavior, sexual orientation, sexual functioning, and psychologic adjustment. Furthermore, decisions made about the sex of an infant by doctors and parents do not always turn out to be correct; the person may grow up feeling uncertain about his or her gender identity, or worse still, harbor a sense of outrage about their life and treatment experiences. Such a person will have definite views about hormonal therapy when the time comes and skillful counseling will be needed. A vigorous debate about ethical aspects of current medical practices relating to intersex conditions has been waged for the last 7 years between certain patient advocacy organizations and the medical profession, and is expected to continue for some time. The quality of the debate will be improved by evidence. The results of a number of long-term follow-up studies have been published, and more are expected. The published studies show mixed, but mainly encouraging, results.

Intersex and gender assignment; the third way?

The birth of a new baby is one of the greatest wonders of nature and one of the most exciting events known to man. The first question that is usually posed by the mother or father is "is it a boy or a girl?"; without this information the new parents cannot even formulate the second question which is usually "is he/she alright?". It is no wonder that the birth of a child with complex genital anomalies where the sex of rearing is uncertain at birth, presents difficult clinical and ethical issues.
