Intersex in humans refers to intermediate or atypical combinations of physical features that usually distinguish female from male. This is usually understood to be congenital involving chromosomal morphologic genital and/or gonadal anomalies such as diversion from typical XX-female or XY-male presentations e.g. sex reversal (XY-female XX-male) genital ambiguity sex developmental differences. An intersex individual may have biological characteristics of both the male and female sexes.1 Intersexuality as a term was adopted by medicine during the 20th century and applied to human beings whose biological sex cannot be classified as clearly male or female.234 Intersex was initially adopted by intersex activists who criticize traditional medical approaches to sex assignment and seek to be heard in the construction of new approaches.56
Some people (whether physically intersex or not) do not identify themselves as either exclusively female or male. Androgyny is sometimes used to refer to those without gender-specific physical sexual characteristics or sexual preferences or gender identity or some combination of these.7 This state may or may not include a mixture or absence of sexual preferences.89 Contents 1 Language 1.1 Nomenclature 1.1.1 Hermaphrodite 1.1.2 Disorders of sex development 2 Intersex people in society 2.1 History 2.2 Sociological approaches 2.3 Recent debates 2.3.1 Intersex identity 2.3.2 Surgery 2.3.3 Experience of medical procedures and photography 2.3.4 Gender incongruence 2.4 Intersex in popular culture 2.5 Education 2.6 Notable intersex people 2.7 Discussion in media and on internet 2.8 Noted researchers on intersex development 2.9 Intersex organizations 3 Intersex conditions and scope 3.1 Prevalence 3.2 Signs 3.2.1 Ambiguous genitalia 3.2.1.1 "True hermaphroditism" 3.2.1.2 Ovotestes 3.2.2 Other diagnostic signs 3.3 Management 3.3.1 Surgery 3.4 Causes 3.4.1 Typical sex development 3.4.2 Conditions 3.5 Complications 4 See also 5 References 6 Bibliography 7 External links // Language
Research in the late 20th century has led to a growing medical consensus that diverse intersex physicalities are normal but relatively rare forms of human biology. Milton Diamond one of the most outspoken experts on matters affecting intersex people stresses the importance of care in the selection of language related to such people. Foremost we advocate use of the terms "typical" "usual" or "most frequent" where it is more common to use the term "normal." When possible avoid expressions like maldeveloped or undeveloped errors of development defective genitals abnormal or mistakes of nature. Emphasize that all of these conditions are biologically understandable while they are statistically uncommon.10 Nomenclature Hermaphrodite Main article: Hermaphrodite
A hermaphrodite is a plant or animal that has both male and female reproductive organs. Disorders of sex development Main article: Disorders of sex development
The term is defined by congenital conditions in which development of chromosomal gonadal or anatomical sex is atypical.
The Intersex Society of North America intersex activists medical experts and parents have moved to eliminate the term "intersex" in medical usage replacing it with disorders of sex development (DSD) in order to avoid conflating anatomy with identity.11 Members of the Lawson Wilkins Pediatric Endocrine Society12 and the European Society for Paediatric Endocrinology13 accepted this term in their "Consensus statement on management of intersex disorders" published in the Archives of Disease in Children14 and in Pediatrics.15
Other intersex people activists supporters and academics have contested the adoption of the terminology seeing it as offensive to intersex individuals who do not feel that there is something wrong with them regard the DSD consensus paper as reinforcing the normativity of early surgical interventions and criticising the treatment protocols associated with the new taxonomy.161718 Alternatives to categorising intersex conditions as "disorders" have been suggested including "variations of sex development".19 Organisation Intersex International questions a disease/disability approach argues for deferral of intervention unless medically necessary when fully informed consent of the individual involved is possible and self-determination of sex/gender orientation and identity.20 Intersex people in society History Hermaphroditus a colored engraving from a Pompeian fresco by French School c.1800.
Intersex people are treated in different ways by different cultures. In some cultures such people were included in larger "third gender" or gender-blending social roles along with other individuals. In most societies intersexed people have been expected to conform to either a female or male gender role.21
Whether or not they were socially tolerated or accepted by any particular culture the existence of intersex people was known to many ancient and pre-modern cultures. An example is one of the Sumerian creation myths from more than 4000 years ago. The story has Ninmah a mother goddess fashioning mankind out of clay.22 She boasts that she will deter

During the Victorian era medical authors introduced the terms "true hermaphrodite" for an individual who has both ovarian and testicular tissue verified under a microscope "male pseudo-hermaphrodite" for a person with testicular tissue but either female or ambiguous sexual anatomy and "female pseudo-hermaphrodite" for a person with ovarian tissue but either male or ambiguous sexual anatomy. In Europe the term 'intersexual' was first to be used before the 2nd World War.23 The first call to replace the term 'hermaphrodite' with 'intersex' came from British specialist Cawadias in the 1940s.24 This suggestion was taken up by specialists in the UK during the 1960s by both those who rejected Money's framework (then emerging from the USA)25 and those who endorsed that approach.26
Since the rise of modern medical science in Western societies some intersex people with ambiguous external genitalia have had their genitalia surgically modified to resemble either female or male genitals. Ironically since the advancements in surgery have made it possible for intersex conditions to be concealed many people are not aware of how frequently intersex conditions arise in human beings or that they occur at all.27 Contemporary social activists scientists and health practitioners among others have begun to revisit the issue and awareness of the existence of physical sexual variation in human beings is returning.
There are increasing calls for recognition of the various degrees of intersex as healthy variations which should not be subject to correction. Some have attacked the common Western practice of performing corrective surgery on the genitals of intersex people as a Western cultural equivalent of female genital cutting. Despite the attacks on the practice most of the medical profession still supports it although activism has radically altered medical policies and how intersex patients and their families are treated.2829
The writer Anne Fausto-Sterling coined the words herm (for "true hermaphrodite") merm (for "male pseudo-hermaphrodite") and ferm (for "female pseudo-hermaphrodite") and proposed that these be recognized as sexes along with female and male. However her use was "tongue-in-cheek"; she no longer advocates these terms even as a rhetorical device and her proposed nomenclature was criticized by Cheryl Chase in a letter to The Sciences which criticized the traditional standard of medical care as well as Fausto-Sterling's shorter names and announced the creation of the Intersex Society of North America. Sociological approaches
The first sociologist to work on 'intersexuality' was Harold Garfinkel in 1967 using a method derived from sociological phenomenology he called ethnomethodology. He based his analysis on the everyday commonsense understandings of 'Agnes' a woman undergoing social and surgical gender reassignment.30 Ethnomethodology was also used in 1978 by Kessler and McKenna who argue that while gender can be seen as a social accomplishment cross-cultural studies render gender as problematic as they highlight how it is usually regarded as a fact when it can be shown to be constructed in different ways. They point to different cultural approaches to gender roles and how 'hermaphrodites' and 'berdaches' are incorporated socially as disruptive to fixed ideas about sex gender and gender-roles. They argue that what we 'know' about gender is grounded in the 'everyday social construction of a world of two genders' where gender attribution seems more important than gender differentiation.31 Recent debates Intersex identity
Some people with intersex conditions self-identify as intersex and some do not.3233 Surgery
Depending on the type of intersex condition corrective surgery may be performed not for protection of life or health but for aesthetic or social purposes. Unlike other aesthetic surgical procedures performed on infants such as corrective surgery for a cleft lip (as opposed to a cleft palate) genital surgery may lead to negative consequences for sexual functioning in later life (such as loss of sensation in the genitals; for example when a clitoris deemed too large/penile is reduced/removed) or feelings of freakishness and unacceptability which would have been avoided without the surgery. In other cases negative consequences may be avoided with surgery.

no compelling evidence that the presumed social benefits of such "normalizing" surgery outweigh the potential costs.34 (Similar attitudes are present in some cases of botched infant circumcision in which the solution might involve intensive medical and parental efforts to reassign the male baby to a female identity which opponents claim lead to the degrading interpretation that females are essentially castrated males. This view overlooks the embryological origin of the penis/clitoris.)
Defenders of the practice argue that it is necessary for individuals to be clearly identified as male or female in order for them to function socially. However many intersex individuals have resented the medical intervention and some have been so discontented with their surgically assigned gender as to opt for sexual reassignment surgery later in life. The Declaration of Montreal first demanded prohibition of unnecessary post-birth surgery to reinforce gender assignment until a child is old enough to understand and give informed consent. This was detailed in the context of existing UN declarations and conventions under Principle 18 of The Yogyakarta Principles which called on states to:
B. Take all necessary legislative administrative and other measures to ensure that no childs body is irreversibly altered by medical procedures in an attempt to impose a gender identity without the full free and informed consent of the child in accordance with the age and maturity of the child and guided by the principle that in all actions concerning children the best interests of the child shall be a primary consideration; C. Establish child protection mechanisms whereby no child is at risk of or subjected to medical abuse; The Yogyakarta Principles
Intersex advocates and experts have critiqued the necessity of early interventions citing individual's experiences of intervention and the lack of follow-up studies showing clear benefits. Specialists at the Intersex Clinic at University College London began to publish evidence in 2001 that indicated the harm that can arise as a result of inappropriate interventions and advised minimising the use of childhood surgical procedures.35363738394041424344 Experience of medical procedures and photography

Sax's strict definition of intersex is most relevant to family practice and psychological research. Other interest groups serve different communities and concerns and so broaden the definition of intersex in these fields.

The prevalence of intersex depends on which definition is used.

Ambiguous genitalia appear as a large clitoris or small penis and may or may not require surgery.
Because there is variation in all of the processes of the development of the sex organs a child can be born with a sexual anatomy that is typically female or feminine in appearance with a larger than average clitoris (clitoral hypertrophy); or typically male masculine in appearance with a smaller than average penis that is open along the underside.

ender in terms of the histology (microscopic appearance) of the gonads.84
"True hermaphroditism"
With some conditions of intersex even the chromosomal sex may not be clear. A "true hermaphrodite" is defined as someone with both male gonadal tissue (testes) and female gonadal tissue (ovarian tissue).
In 2003 researchers at UCLA published their studies of a lateral gynandromorphic hermaphroditic zebra finch which had a testicle on the right and an ovary on the left. Its entire body was split down the middle between female and male with hormones from both gonads running through the blood.85 This is an example of mosaicism or chimerism.
This extreme example of hermaphroditism is quite rare. Ovotestes
Although there are no definite reports on any true hermaphroditism in humans there is on the other hand a spectrum of forms of ovotestes. The varieties range including having two ovotestes or having one ovary and one ovotestis. This is often in the form of streak gonads. Phenotype is not determinable from the ovotestes; in some cases the appearance is "fairly typically female" in others it is "fairly typically male" and it may also be "fairly in-between in terms of genital development."86
Intersex activist Cheryl Chase is an example of someone with ovotestes.60 Other diagnostic signs
In order to help in classification methods other than a genitalia inspection can be performed:
For instance a karyotype display of a tissue sample may determine which of the causes of intersex is prevalent in the case. Management
Management of intersex can be categorized into one of the following two:87 Treatments: Restore functionality (or potential functionality) Enhancements: Give the ability to identify with mainstream people e.g. breast enlargement surgery
However there are other categorisation systems of management of intersexed which falls into neither category.88
In any case the most common procedure is surgery. Surgery
The exact procedure of the surgery depends on what is the cause of a less common body phenotype in the first place. There is often concern whether surgery should be performed at all. A traditional approach to the management of intersexuality has been socially motivated surgery. However some88 (Alice Dreger) say that surgical treatment is socially motivated and hence ethically questionable; without evidence doctors regularly assume that intersexed persons can not have a clear identity. This is often taken further with parents of intersexed babies advised that without surgery their child will be stigmatized. Further since almost all such surgeries are undertaken to fashion female genitalia for the child it is more difficult for the child to present as male if they later select a male gender identity. 20% to 30% of surgical cases result in a loss of sexual sensation (Newman 1991 1992).

Causes Typical sex development Main article: Sexual differentiation
The common pathway of sexual differentiation where a productive human female has an XX chromosome pair and a productive male has an XY pair is relevant to the development of intersexed conditions.
During fertilization the sperm adds either an X (female) or Y (male) chromosome to the X in the ovum. This determines the genetic sex of the embryo.89 During the first weeks of development genetic male and female fetuses are "anatomically indistinguishable" with primitive gonads beginning to develop during approximately the sixth week of gestation. The gonads in a "bipotential state" may develop into either testes (the male gonads) or ovaries (the female gonads) depending on the consequent events.89 Through the seventh week female and male fetuses appear identical.
At around eight weeks of gestation the gonads of an XY embryo differentiate into functional testes secreting testosterone. Ovarian differentiation for XX embryos does not occur until approximately Week 12 of gestation. In normal female differentiation the Mllerian duct system develops into the uterus Fallopian tubes and inner third of the vagina. In males the Mllerian duct-inhibiting hormone MIH causes this duct system to regress. Next androgens cause the development of the Wolffian duct system which develops into the vas deferens seminal vesicles and ejaculatory ducts.89 By birth the typical fetus has been completely "sexed" male or female the hormones and genital development remaining consistent with the genetic sex.

With some conditions of intersex even the chromosomal sex may not be clear. A "true hermaphrodite" is defined as someone with both male gonadal tissue (testes) and female gonadal tissue (ovarian tissue).
In 2003 researchers at UCLA published their studies of a lateral gynandromorphic hermaphroditic zebra finch which had a testicle on the right and an ovary on the left. Its entire body was split down the middle between female and male with hormones from both gonads running through the blood.85 This is an example of mosaicism or chimerism.
This extreme example of hermaphroditism is quite rare. Ovotestes
Although there are no definite reports on any true hermaphroditism in humans there is on the other hand a spectrum of forms of ovotestes. The varieties range including having two ovotestes or having one ovary and one ovotestis. This is often in the form of streak gonads. Phenotype is not determinable from the ovotestes; in some cases the appearance is "fairly typically female" in others it is "fairly typically male" and it may also be "fairly in-between in terms of genital development."86
Intersex activist Cheryl Chase is an example of someone with ovotestes.60 Other diagnostic signs
In order to help in classification methods other than a genitalia inspection can be performed:
For instance a karyotype display of a tissue sample may determine which of the causes of intersex is prevalent in the case. Management
Management of intersex can be categorized into one of the following two:87 Treatments: Restore functionality (or potential functionality) Enhancements: Give the ability to identify with mainstream people e.g. breast enlargement surgery
However there are other categorisation systems of management of intersexed which falls into neither category.88
In any case the most common procedure is surgery. Surgery
The exact procedure of the surgery depends on what is the cause of a less common body phenotype in the first place. There is often concern whether surgery should be performed at all. A traditional approach to the management of intersexuality has been socially motivated surgery. However some88 (Alice Dreger) say that surgical treatment is socially motivated and hence ethically questionable; without evidence doctors regularly assume that intersexed persons can not have a clear identity. This is often taken further with parents of intersexed babies advised that without surgery their child will be stigmatized. Further since almost all such surgeries are undertaken to fashion female genitalia for the child it is more difficult for the child to present as male if they later select a male gender identity. 20% to 30% of surgical cases result in a loss of sexual sensation (Newman 1991 1992).

Congenital adrenal hyperplasia (CAH)
The most common cause of sexual ambiguity is congenital adrenal hyperplasia (CAH) an endocrine disorder in which the adrenal glands produce abnormally high levels of virilizing hormones.
In people without a Y chromosome (i.e. XX) this can range from partial masculinisation that produces a large clitoris to virilisation and male appearance. The latter applies in particular to Congenital adrenal hyperplasia due to 21-hydroxylase deficiency which is the most common form of CAH.
Individuals born with XX chromosomes affected by 17-hydroxylase deficiency are born with female internal and external anatomy but at puberty neither the adrenals nor the ovaries can produce sex-hormones inhibiting breast development and the growth of pubic hair.
See below for XY CAH 17-hydroxylase deficiency. XX Progestin-induced virilisation In this case the male hormones are caused by use of progestin a drug that was used in the 1950s and 1960s in order to prevent miscarriage. These individuals normally have internal and external female anatomy with functional ovaries and will therefore have menstruation. They develop however some male secondary characteristics and they frequently have unusually large clitorises. In very advanced cases such children have initially been identified as males.91 XX Freemartinism This condition occurs commonly in all species of cattle and affects most females born as a twin to a male. It is rare or unknown in other mammals including humans. In cattle the placentae of fraternal twins usually fuse at some time during the pregnancy and the twins then share their blood supply. If the twins are of different sexes male hormones produced in the body of the fetal bull find their way into the body of the fetal heifer (female) and masculinize her. Her sexual organs do not develop fully and her ovaries may even contain testicular tissue. When adult such a freemartin is very like a normal female in external appearance but she is infertile and behaves more like a castrated male (a steer). The male twin is not significantly affected although (if he remains entire) his testes may be slightly reduced in size. The degree of masculinization of the freemartin depends on the stage of pregnancy at which the placental fusion occurs in about ten percent of such births no fusion occurs and both calves develop normally as in other mammals. XY Androgen insensitivity syndrome (AIS) People with AIS have a Y chromosome (typically XY) but are unable to metabolize androgens in varying degrees.
Cases with typically female appearance and genitalia are said to have complete androgen insensitivity syndrome (CAIS). People with CAIS have a vagina and no uterus cervix or ovaries and are infertile. The vagina may be shorter than usual and in some cases is nearly absent. Instead of female internal reproductive organs a person with CAIS has undescended or partially descended testes of which the person may not even be aware.
In mild and partial androgen insensitivity syndrome (MAIS and PAIS) the body is partially receptive to androgens so there is virilization to varying degrees. PAIS can result in genital ambiguity due to limited metabolization of the androgens produced by the testes. Ambiguous genitalia may present as a large clitoris known as clitoromegaly or a small penis which is called micropenis or microphallus; hypospadias and cryptorchidism may also be present with one or both testes undescended and hypospadias appearing just below the glans on an otherwise typical male penis or at the base of the shaft or at the perineum and including a bifid (or cleft) scrotum. XY 5-alpha-reductase deficiency (5-ARD) The condition affects individuals with a Y chromosome making their bodies unable to convert testosterone to dihydrotestosterone (DHT). DHT is necessary for the development of male genitalia in utero and plays no role in female development so its absence tends to result in ambiguous genitalia at birth; the effects can range from infertility with male genitalia to male underdevelopment with hypospadias to female genitalia with mild clitoromegaly. The frequency is unknown and children are sometimes misdiagnosed as having AIS.92 Individuals can have testes as well as vagina and labia and a small penis capable of ejaculation that looks like a clitoris at birth. Such individuals are usually raised as girls. The lack of DHT also limits the development of facial hair. XY Congenital adrenal hyperplasia (CAH) In individuals with a Y chromosome (typically XY) who have Congenital adrenal hyperplasia due to 17 alpha-hydroxylase deficiency CAH inhibits virilization unlike cases without a Y chromosome. XY Persistent Mllerian duct syndrome (PMDS) The child has XY chromosomes typical of a male. The child has a male body and an internal uterus and fallopian tubes because his body did not produce Mllerian inhibiting factor during fetal development.

Mosaicism and chimerism
A mix can occur where some of the cells of the body have the common XX or XY while some have one of the less usual chromosomal contents above. Such a mixture is caused by either mosaicism or chimerism. In mosaicism the mixture is caused by a mutation in one of the cells of the embryo after fertilization while chimerism is a fusion of two embryos.
Alternatively it is simply a mixture between XX and XY and doesn't have to involve any less common genotypes in individual cells. This too can occur both as a chimerism or that one sex chromosome has mutated into the other.93
However not all cases of mosaicism and chimerism involve intersex. Complications
In the cases where nonfunctional testes are present there is a risk that these develop cancer. Therefore doctors either remove them by orchidectomy or monitor them carefully. This is the case for instance in androgen insensitivity syndrome.
