Original Paper


The medical management of differences of sex development (DSD)/intersex in early childhood has been criticized by patients’ advocates as well as bioethicists from an ethical point of view. Some call for a moratorium of any feminizing or masculinizing operations before the age of consent except for medical emergencies. No exhaustive ethical guidelines have been published until now. In particular, the role of the parents as legal representatives of the child is controversial. In the article, we develop, discuss, and present ethical principles and recommendations for the medical management of intersex/DSD in children and adolescents. We specify three basic ethical principles that have to be respected and substantiate them. The article includes a critical discussion of the best interest of the child and of family privacy. The argumentation draws upon recommendations by the working group “Bioethics and Intersex” within the German Network DSD/Intersex, which are presented in detail. Unlike other recommendations with regard to intersex, these guidelines represent a comprehensive view of the perspectives of clinicians, patients, and their families.


The working group identified three leading ethical principles that apply to DSD management: (1) to foster the well-being of the child and the future adult, (2) to uphold the rights of children and adolescents to participate in and/or self-determine decisions that affect them now or later, and (3) to respect the family and parent–child relationships. Nine recommendations for the management of DSD indicate how these ethical principles can spelled out and balanced against each other in the clinical setting.


Intersex Disorders of sex development Ethics Informed consent Guidelines 

Differences of sex development (DSD)1—or intersex as it is sometimes called—has recently attracted considerable attention by pediatricians, endocrinologists, psychologists, and geneticists, as well as feminists, ethicists, and self-help groups [1, 2, 3, 4, 5, 6]. A number of articles have been published to clarify the role medicine should play in shaping sex and gender identity in children with DSD. The new literature indicates a shift of the paradigm of a so-called “optimal-gender policy,” a term coined by the early pioneering group in the field from Johns Hopkins University in the 1960s. At the time, early corrective surgery was thought to help the affected children as well as their parents to facilitate stable gender identity and appropriate gender role behavior [7, 8, 9]. Sex assignment of infants with ambiguous genitalia often resulted in feminizing operations in moderate or severe undervirilization in 46,XY DSD as well as 46,XX conditions with severe masculinization. Those critical of early surgery aiming at normal or near normal appearance argue that the complexity of gender identity was not considered adequately, and the mutilating and traumatizing effects of treatment were not sufficiently taken into account. Other than in the case of medical emergencies, they now advocate a moratorium in any feminizing or masculinizing operations before full consent may be obtained from the child [10, 11]. This strategy can be called “full-consent policy.”

Today, guidelines from medical societies still endorse techniques like clitoris reduction or vagina surgery in the newborn or infant, albeit more cautiously than before [12, 13]. However, the underlying ethical principles of DSD management have not been seriously scrutinized since Kenneth Kipnis and Milton Diamond’s harsh criticism in the Journal of Clinical Ethics of the “optimal-gender policy,” particularly for the deficiencies in informed decision making [11]. In 2004, an ad hoc group at the Hastings Center for Bioethics comprising clinicians, philosophers, and bioethicists, called for a multidisciplinary approach to the management of DSD, the child’s right to know and rigorous follow-up studies but avoided tackling the contentious issue of decision making in early childhood [14]. A Consensus Statement on Management of Intersex Disorders issued by the participants of an International Consensus Conference in 2006 involving pediatric specialists from the United States, Great Britain, and Germany endorsed open communication, a reflective stance on gender identity and a focus on quality of life issues—encompassing “falling in love, dating, attraction, ability to develop intimate relationship, sexual functioning, and the opportunity to marry and raise children”—rather than the biological indicators of sex [15]. This statement offers a thorough appraisal of clinical procedures and psychosocial requirements but fails to give sound ethical arguments for the proposed strategies.

The aim of this paper is to identify and critically discuss those ethical principles that should be respected in medical decision making. Our argumentation draws upon the recommendations by the working group “Bioethics and Intersex” within the German Network DSD/Intersex, which are presented and developed in detail. We will delineate how the rights of the child and the future adult can best be defended by exploring the meaning of patient autonomy. We will also show why a moratorium on nonemergency intersex surgery in early childhood is not justified from an ethical point of view, and why family privacy has to be taken into account.

Working group “bioethics and intersex” within the German Network DSD/Intersex

Since 2004, a research network on DSD/intersex has been in operation in Germany, funded by the German Ministry of Education and Research within the research program for rare diseases. As part of the network, a working group “Bioethics and Intersex” was established to discuss guiding ethical principles and develop ethical guidelines for the clinical management of children with ambiguous genitalia.

The working group adopted a catalog of “Ethical principles and recommendations for the therapeutic management of differences of sex development (DSD)/Intersexuality in children and adolescents” outlined below. The working group consisted of members of patient support groups (persons with DSD/intersex and/or parents); bioethicists; specialists in pediatrics and adolescent medicine, surgery, urology, obstetrics and gynecology, endocrinology; a psychologist and psychotherapist; a specialist in medical law; and a medical sociologist. In a series of meetings, they familiarized themselves with the ethical, legal, psychosocial, and medical aspects concerning this subject and communicated with numerous experts in the field. The working group critically reviewed the diagnostic and therapeutic options available for individuals with ambiguous genitalia in the light of common bioethical principles. We have
  • analyzed the concepts of health, disease, and quality of life with respect to interventions in persons with discordant chromosomal, gonadal, and anatomical sex, but without any acute health risks;

  • delineated the fundamental conflicts and ethical principles which should guide any medical and surgical interventions;

  • established the rights of children and the rights and duties of the parents and health-care teams with regard to these issues and developed a standard for decision making (based on informed consent).

A draft of the ethical principles and recommendations designed for the health-care team has been submitted to all members of the network for feedback and discussion.

Why are the ethical principles of DSD management contentious?

The ethics work group identified four scientific and social tendencies as the major driving forces that led to a thorough reappraisal of former treatment regimes in DSD: (1) increasing knowledge about sex determination and differentiation and the complicated interaction of genotype and phenotype; (2) modern society’s decreasing rigidity about the nature of sexual identity and gender roles following the women’s liberation movement; (3) a growing unease about paternalism in medicine along with the advocacy of patients’ and children’s rights; and (4) the growing importance of patient support groups in the assessment of medical interventions. These factors have helped to re-evaluate the rationality of the “optimal-gender policy,” once recommended by John Money and others. This strategy aimed at benefiting the child as well as the family by creating social certainty through surgical interventions “normalizing” the appearance of the external genitalia. At the time, the impact of hormones on the brain and other organs was underestimated, and the social impact of the stigma of being different was believed to create great distress for individuals affected by DSD. The concept has meanwhile fallen short of expectations. Its major shortcomings included: it was based on less than satisfactory scientific evidence of the long-term outcomes; it privileged phenotypic normalcy over bodily integrity and—to some extent also—quality of life; it systematically neglected the trauma inflicted on the child by medical interventions; and it often meant that neither the child and the future adult nor the parents were educated about the nature of the disorder and the purpose and extent of medical interventions. The last aspect—the secrecy within families and lack of informed consent even in adolescents—is in fact now considered the most problematic issue, as it immunized physicians’ and parents’ convictions from being falsified.

Meanwhile, intersex activists and the medical community itself have demanded for more evidence on the long-term outcome with regard not just to appearance but also to sexual satisfaction, reproductive functions, gender identity, and quality of life. As these data can only be provided when the patients and their families are fully informed about their condition, optimal gender policy has lost its attractiveness as a comprehensive and successful strategy for managing DSD.

Patient autonomy and postponed informed consent

Some critics believe that informed consent by patients is the only way to legitimate appearance-normalizing surgery in DSD. Given the importance of this ethical concept in modern medicine, this is no surprise [15]. Without the competent patient’s informed consent, a medical intervention amounts to battery [16]. Critics of early surgical interventions have cast doubt on parental surrogate decision making. Parents’ surrogacy, they argue, should extend merely to decisions that are in the objective best interest of the child [17, 18]. The appearance of the external genitalia in DSD generally causes no medical problems or immediate health threats to the child. Moreover, most surgical interventions are irreversible and may restrict later options for sex reversal. As it is difficult to find out what is in the best interest of the child, nobody, the argument goes, should decide on these important questions except the patient him/herself. This position entails postponing minor interventions at least until the age of 5 or 6, when the child is able to express preferences and major interventions until the age of 12 to 14.

Although appealing in its simplicity, the argument, however, is flawed: it does not sufficiently distinguish between the interests of the child, particularly the small one, and those of the future adult. That which benefits the child at the age of 3 or 4 and the teenager or adult at 15 or 20, might not be identical at all. Whereas the small child might depend upon a stable gender identity role and undisturbed relations to his or her peers and prefer conformity over independence, the young grown-up might cherish authenticity, independence, and the right freely to choose relationships that suit him or her well. According to the maxim of postponed informed consent, only the adult would be truly able to determine the best interests of the child he or she was in a former time. But this child no longer exists, and its interests, thus, can no longer be respected.

For example, a child with incomplete Androgen Insensitivity Syndrome raised as a girl might in puberty face the effects of virilizing hormones. Hormone suppression has to start before puberty to avoid the effects of male-typical pubertal development and to prevent major disturbances in gender identity. Postponing this decision to the age of consent, however, means closing an important window of opportunity for the child. The future adult’s consent, thus, will be meaningless, because no decision will undo the consequences of a waiver of treatment in the past. Like “optimal-gender policy,” the strategy of postponed consent also has a self-immunizing tendency, as it implicitly treats the small child’s wishes as irrelevant. Demanding a surgical moratorium until the age of consent had been an understandable reaction to nonjustified surgical optimism in the past, but nevertheless resembles the strategy in an old joke: A man has lost his keys in the dark, but is looking for them under a street lamp since he would otherwise not be able to find them.

Family privacy and the best interest of the child

A sound ethical justification for treatment decisions in early childhood is indeed the key to decision making in DSD. The right to represent the child and to decide on its behalf is normally accorded to the parents as legal guardians. However, their role in DSD management is contested. Dayner et al., e.g., showed that parents of 46,XX children with congenital adrenal hyperplasia mostly are in favor of early genital clitoris reduction, even at the risk of reducing genital sensitivity, although it is not clear that this is in the interest of the child [19]. Patient support groups argue that “in intersex conditions the parents’ wishes often conflict with the child’s ultimate best interest” [20, 21].

The double superlative “ultimate best,” however, hints to some characteristic difficulties associated with the so-called best interest standard in pediatric ethics that might step in, in the place of informed consent. Ethicists agree upon the fact that the lower threshold of what is definitely not in the interest of the child can be fixed, such as anything that is purposefully destructive or even life-threatening. They would also agree on what counts as an ethical minimum of parental care, such as adequate clothing, nourishment, and education [22, 23]. However, this is far from establishing an objective ethical maximum as is implied by the notion “best” (let alone “ultimate best”) in best interest standard. In modern pluralistic societies, there is no such criterion as an objective best interest standard for child care. Although quite commonly used in ethical debate, this notion is misleading and should be abandoned because it suggests an objective external value system with a linear scale, which does not exist, for optimal parental behavior [24, 25]. Parents and families are instead accorded a certain sphere of privacy to pursue their personal aims and find out what is their best in child care [26]. The Universal Declaration of Human Rights, for example, acknowledges this fact when stating: “The family is the natural and fundamental group unit of society and is entitled to protection by society and the State” [27]. Protection for the child means not just protection by but also protection from society and the state. The same attitude is expressed by the UN Convention of the Rights of the Child. The signing states are “convinced that the family, as the fundamental group of society and the natural environment for the growth and well-being of all its members and particularly children, should be afforded the necessary protection and assistance so that it can fully assume its responsibilities within the community” [28].

Thus, parents take first-line responsibility in defining what might be best for the child, and this may rightly vary according to their individual experience and life style, cultural expectations, and beliefs. The right to familial privacy, however, is not unlimited. It has to comply with the ethos of parenthood determined by the larger cultural context, not just by the individual parents themselves. This almost universal ethos demands both a caring and encouraging human relationship between parent and child and respect for each and every child [29]. The way in which parents are expected to live up to this ethos has to be socially negotiated in line with social, cultural, or religious attitudes.

The nature and extent of restrictions the state may impose upon the family to protect children from harm and to help parents realize the ethos of parenthood is an ongoing controversy in modern societies. The debate on in vitro fertilization for gay couples is one example; the limits of parental discretion and decision making about a child’s sex and gender identity is another.

Given the importance of supportive personal relationships for children in general and the difficulties in objectively and externally defining the child’s best interest, parents should play a major role in the decision-making process in DSD management. Given the complexity of interaction between biological, psychological, social, and cultural factors, it is also essential to make decisions on a case-by-case basis. This forecloses such sweeping recommendations for each and every case like a general moratorium on surgical interventions in DSD in early childhood, as well as simple formulas for the treatment of particular disease conditions. Biological, psychological, and social factors have an influence on the outcome of a case and make each intersex condition unique. The individual characteristics of the child, the family, and the social background have a bearing on the benefits to be achieved for the child and thus, have to be taken into account.

Nevertheless, it is necessary to outline some general principles limiting parental discretion in accordance with commonly shared beliefs of the good parent on one hand and of the child’s human dignity and bodily integrity on the other hand. First of all, the child itself is to be respected as another major player in the decision-making process. Even the small child can express preferences or vetoes. As early as the age of 6 or 7, children are able to understand biological processes or to reflect on their identity [30]. The child, therefore, should be granted partnership status and be involved in all examination and treatment steps, as appropriate to his or her developmental level. This helps to modify the family perspective usually represented by the parents.

Secondly, all persons involved should be aware of the fact that a good parent–child relationship is the result of a process of continuing efforts and not just a state of mind. It can be facilitated by appropriate therapeutic interventions. Due to the psychosocial stress associated with DSD, parents need help in establishing a good relationship with their child. Psychological support should always be sought to help families to strive for a good relationship with the child and to support the child in developing supportive relationships in the peer group. If the family’s right to decision making is endorsed, the relationships within the family deserve careful consideration and have to be included in the therapeutic process. Thirdly, the outcome—as judged by minor and adult intersex patients—of any intervention should be continuously and carefully evaluated and inform future treatment recommendations.


The working group identified three ethical principles relevant to decision making in DSD. First of all, the well-being of the child and of the future adult has to be fostered. It is important to note that the surgical creation of unambiguous external genitalia is neither necessary nor sufficient criterion for well-being and is sometimes impossible to achieve; bodily integrity and quality of life, particularly with respect to reproductive capability as well as the ability to experience sex, and the free development of the child’s personality have also to be taken into account. Secondly, the rights of the patients to participate in and/or self-determine decisions that affect them now or later have to be respected. This includes the right of the future adult to be comprehensively informed about their condition and about all interventions carried out as well as the health-care team’s obligation to provide the appropriate information and maintain documentation. Thirdly, family and parent–child relationships should be fostered. Parents have the right to represent their child in the decision-making process, particularly when there is no clear evidence of the outcome of medical interventions and when the interest of the small child and the future adult might not be identical. The health-care team has to strengthen the ability of parents to cope with the situation and to support their child. For that purpose, parents have to receive professional support and assistance.

The Ethics Work Group was aware of the fact that these three principles often conflict. Nine recommendations for the management of DSD published below indicate how they can be balanced against each other in the clinical setting.

Decision making concerning sex assignment and consequent surgical interventions are hampered by the lack of evidence in many conditions causing ambiguous genitalia in newborns or children during their development. All decisions must be based on the individual’s unique condition and prognosis from a biological and social perspective. Thus, we foster a shift in paradigm from optimal appearance and potential functioning to optimal emotional and social development trying to maximize the child’s and future adults’ participation in decision making on one hand and a good parent–child relationship on the other.

    The term DSD meaning disorders of sex development was coined by the International Consensus Conference (2006). The notion “disorders,” however, is criticized for its pathologizing tendency. In this paper, we use the terms “differences in sex development” or “intersex” to avoid a biased opinion. The field of intersex shows a wide range of variations from the statistically normal. We understand that in Western societies, there is a ongoing debate on which variations of sex development should be classified as male or female, normal or not normal, in need of a medical intervention or not, disorder or difference. This debate is unlikely to come to an end soon. For example, homosexuality was treated as a biological and psychological abnormality of sexual development, but is no longer today. Normality in medicine is a biological as well as a social criterion, and its meaning is changing over time. The notion “disease” or “disorder” implies that something is a relevant abnormality and that medicine is in charge of it. We want to avoid this reflex. However, we do not deny that there may be conditions requiring medical intervention.
