Surgery is sometimes performed to alter the appearance of the genitals. However many surgeries performed on intersex people lack clear evidence of necessity, can be considered as mutilating, and are widely considered to be human rights violations when performed without the informed consent of the recipient.

Management of AIS is currently limited to symptomatic management; no method is currently available to correct the malfunctioning androgen receptor proteins produced by "AR" gene mutations. Areas of management include sex assignment, genitoplasty, gonadectomy in relation to tumor risk, hormone replacement therapy, genetic counseling, and psychological counseling.

Medical interventions take place to address physical health concerns, and psychosocial risks. Both types of rationale are the subject of debate, particularly as the consequences of surgical (and many hormonal) interventions are lifelong and irreversible. Questions regarding physical health include accurately assessing risk levels, necessity and timing. Psychosocial rationales are particularly susceptible to questions of necessity as they reflect social and cultural concerns.

There remains no clinical consensus about an evidence base, surgical timing, necessity, type of surgical intervention, and degree of difference warranting intervention. Such surgeries are the subject of significant contention due to consequences that include trauma, impact on sexual function and sensation, and violation of rights to physical and mental integrity. This includes community activism, and multiple reports by international human rights and health institutions and national ethics bodies.

In the cases where gonads may pose a cancer risk, as in some cases of androgen insensitivity syndrome, concern has been expressed that treatment rationales and decision-making regarding cancer risk may encapsulate decisions around a desire for surgical normalization.

Intersex people are born with any of several variations in sex characteristics including chromosomes, gonads, sex hormones, or genitals that, according to the UN Office of the High Commissioner for Human Rights, "do not fit the typical definitions for male or female bodies". Such variations may involve genital ambiguity, and combinations of chromosomal genotype and sexual phenotype other than XY-male and XX-female.

Intersex people were previously referred to as hermaphrodites, "congenital eunuchs", or congenitally "frigid". Such terms have fallen out of favor; in particular, the term "hermaphrodite" is considered to be misleading, stigmatizing, and scientifically specious. Medical description of intersex traits as disorders of sex development has been controversial since the label was introduced in 2006.

Intersex people may face stigmatization and discrimination from birth or discovery of an intersex trait. In some countries, documented in parts of Africa and Asia, this may include infanticide, abandonment and the stigmatization of families. Globally, some intersex infants and children, such as those with ambiguous outer genitalia, are surgically or hormonally altered to create more socially acceptable sex characteristics. However, this is considered controversial, with no firm evidence of good outcomes. Such treatments may involve sterilization. Adults, including elite female athletes, have also been subjects of such treatment. Increasingly these issues are considered human rights abuses, with statements from international and national human rights and ethics institutions. Intersex organizations have also issued statements about human rights violations, including the Malta declaration of the third International Intersex Forum.

In 2011, Christiane Völling became the first intersex person known to have successfully sued for damages in a case brought for non-consensual surgical intervention. In April 2015, Malta became the first country to outlaw non-consensual medical interventions to modify sex anatomy, including that of intersex people.

Some intersex persons may be assigned and raised as a girl or boy but then identify with another gender later in life, while most continue to identify with their assigned sex.

Pseudohermaphroditism, or pseudo-hermaphroditism, is an old clinical term for an organism is born with primary sex characteristics of one sex but develops the secondary sex characteristics that are different from what would be expected on the basis of the gonadal tissue (ovary or testis). It can be contrasted with the term true hermaphroditism, which described a condition where testicular and ovarian tissue were present in the same individual. This language has fallen out of favor due to misconceptions and pejorative connotations associated with the terms, and also a shift to nomenclature based on genetics.

The term "male pseudohermaphrodite" was used when a testis is present, and the term "female pseudohermaphrodite" was used when an ovary is present.

In some cases, external sex organs associated with pseudohermaphroditism look intermediate between a typical clitoris and penis. In other cases, the external sex organs have an appearance that would be expected to be seen with the "opposite" gonadal tissue. Because of this, pseudohermaphroditism is sometimes not identified until puberty or adulthood.

Associated conditions include 5-α-reductase deficiency and androgen insensitivity syndrome.

Disorders of sex development (DSD), sometimes referred to as disorders of sex differentiation or differences of sex development, are medical conditions involving the reproductive system. More specifically, these terms refer to "congenital conditions in which development of chromosomal, gonadal, or anatomical sex is atypical."

The term has been controversial, and research has shown that affected people experience a negative impact, with the terminology impacting choice and utilization of health care providers. The World Health Organization and many medical journals still reference DSDs as intersex traits or conditions. The Council of Europe, and Inter-American Commission on Human Rights have called for a review of medical classifications that unnecessarily medicalize intersex traits.

DSDs are medical conditions involving the way the reproductive system develops from infancy (and before birth) through young adulthood. There are several types of DSDs and their effect on the external and internal reproductive organs varies greatly.

A frequently-used social and medical adjective for people with DSDs is "intersex". Parents with DSD children and clinicians involved in DSD treatment usually try to make clear distinctions between biological sex, social gender, and sexual orientation. This helps reduce confusion about the differences between being intersex, being transgender, and being gay/lesbian.

The most common DSD is congenital adrenal hyperplasia (CAH), which results in a person with female (XX) chromosomes having genitals that look somewhat masculine. In mild cases CAH results in a slightly enlarged clitoris, while in more severe cases it can be difficult to decide (just by looking) whether a baby is male or female (this is called having ambiguous genitals). Nevertheless, if they are old enough to know the difference, most children with CAH think of themselves as girls. CAH is caused by a problem with the adrenal glands and is usually treated by taking a daily medication to replace or supplement the missing adrenal hormones. (When this adrenal problem occurs in people with male (XY) chromosomes, the result is over-masculinization and premature puberty).

Another common DSD is androgen insensitivity syndrome (AIS), which means that a person with male (XY) chromosomes does not respond to testosterone in the usual way. This results in a body that to some degree has a feminine appearance. In Complete Androgen Insensitivity Syndrome (CAIS) the result is a totally feminine appearance, including typical female breast development. Consequently, most young women with CAIS are unaware of their condition until the early teen years when they fail to menstruate. In the milder form, called Partial Androgen Insensitivity Syndrome (PAIS), the genitals can vary from mostly female to almost completely male. Some people with PAIS think of themselves as girls/women, others regard themselves as boys/men, and some consider themselves mixed-gender.

One of the more unusual DSDs is 5-alpha-reductase deficiency (5ARD). It is caused by a shortage early in life of an enzyme that activates testosterone. In this condition, a person with male (XY) chromosomes has a body that appears female before puberty. After puberty begins, other testosterone-activating enzymes become available and the body soon takes on a masculine appearance, with the scrotum and penis usually reaching typical or nearly-typical size. If 5ARD is diagnosed at a young age, the child is often raised as a boy (a 1996 Brazilian study suggested that the majority of adults with this condition consider themselves men but this has been questioned in some more recent research).

In addition to CAH, CAIS, PAIS, and 5ARD there are several rarer types of DSDs, and in some cases it is not possible to make a clear diagnosis of the underlying condition.

The penis and clitoris are essentially the same organ (differing only in size, and generically called the phallus). In typical males, the urethra is located at the tip of the penis, while in typical females the urethra is located below the base of the clitoris. When the phallus is of intermediate size, it is possible also to have a urethral opening located along the shaft; this condition is known as hypospadias.

Open-minded parenting, appropriate and conservative medical intervention, and age-appropriate child involvement in the treatment plan contribute greatly to successful outcomes for the entire range of DSDs.

True hermaphroditism, clinically known as ovotesticular disorder of sex development, is a medical term for an intersex condition in which an individual is born with ovarian and testicular tissue. More commonly one or both gonads is an ovotestis containing both types of tissue.

Although similar in some ways to mixed gonadal dysgenesis, the conditions can be distinguished histologically.

There are no documented cases in which both types of gonadal tissue function.

Although fertility is possible in true hermaphrodites, there has yet to be a documented case where both gonadal tissues function, contrary to the misconception that hermaphrodites can impregnate themselves. As of 2010, there have been at least 11 reported cases of fertility in true hermaphrodite humans in the scientific literature, with one case of a person with XY-predominant (96%) mosaic giving birth.

Androgen insensitivity syndrome (AIS) is an intersex condition in which there is a partial or complete inability of many cells in the affected genetic male to respond to androgenic hormones. This can prevent or impair the masculinization of male genitalia in the developing genetic male (chromosomal XY) fetus, as well as the development of male secondary sexual characteristics at puberty. Clinical phenotypes range from a normal male habitus with mild spermatogenic defect or reduced secondary terminal hair; to a full female habitus despite the presence of a Y-chromosome. Women (chromosomal XX) who are heterozygous for the AR gene have normal primary and secondary sexual characteristics; this female carrier will pass the affected AR gene to any child she has with 50% likelihood. AIS is the largest single entity that leads to 46,XY undermasculinized genitalia.

The androgen receptor (AR), which is defective due to a mutation in most of these syndromes, is a type of nuclear receptor that is activated by binding to either of the androgenic hormones (testosterone or dihydrotestosterone) in the cytoplasm, and then translocates into the nucleus where it binds to DNA, provided androgen response elements and coactivators are present. This combination functions as a transcription complex to turn on androgen gene expression. Thus the AR activates these genes to mediate the effects of androgens in the human body, including the development and maintenance of the male sexual phenotype and generalized anabolic effects. Over 400 AR mutations have been reported.

AIS is divided into three categories that are differentiated by the degree of genital masculinization: complete androgen insensitivity syndrome (CAIS) is indicated when the external genitalia are that of a normal female; mild androgen insensitivity syndrome (MAIS) is indicated when the external genitalia are that of a normal male, and partial androgen insensitivity syndrome (PAIS) is indicated when the external genitalia are partially, but not fully, masculinized.

Management of AIS is currently limited to symptomatic management; no method is currently available to correct the malfunctioning androgen receptor proteins produced by "AR" gene mutations. Areas of management include sex assignment, genitoplasty, gonadectomy in relation to tumor risk, hormone replacement therapy, genetic counseling, and psychological counseling.

Yersiniosis is usually self-limiting and does not require treatment. For severe infections (sepsis, focal infection) especially if associated with immunosuppression, the recommended regimen includes doxycycline in combination with an aminoglycoside. Other antibiotics active against "Y. enterocolitica" include trimethoprim-sulfamethoxasole, fluoroquinolones, ceftriaxone, and chloramphenicol. "Y. enterocolitica" is usually resistant to penicillin G, ampicillin, and cephalotin due to beta-lactamase production.

45,X/46,XY mosaicism, also known as X0/XY mosaicism and mixed gonadal dysgenesis, is a rare disorder of sex development in humans associated with sex chromosome aneuploidy and mosaicism of the Y chromosome. This is called a mosaic karyotype because, like tiles in mosaic floors or walls, there is more than one type of cell.

The clinical manifestations are highly variable, ranging from partial virilisation and ambiguous genitalia at birth, to patients with a completely male or female gonads. Most individuals with this karyotype have apparently normal male genitalia, and a minority with female genitalia, with a significant number of individuals showing genital abnormalities or intersex characteristics. A significantly higher than normal number of other developmental abnormalities are also found in individuals with X0/XY mosaicism. Psychomotor development is normal.

Identification of 45,X/46,XY karyotype has significant clinical implications due to known effects on growth, hormonal balance, gonadal development and histology. 45,X/46,XY is diagnosed by examining the chromosomes in a blood sample.

The age of diagnosis varies depending on manifestations of disease prompting reason for cytogenetic testing. Many patients are diagnosed prenatally due to fetal factors (increased nuchal fold, or abnormal levels of serum), maternal age or abnormal ultrasounds, while others will be diagnosed postnatal due to external genital malformation. It is not uncommon for patients to be diagnosed later in life due to short stature or delayed puberty, or a combination of both.

45,X/46,XY mosaicism can be detected prenatally through amniocentesis however, it was determined that the proportion of 45,X cells in the amniotic fluid cannot predict any phenotypic outcomes, often making prenatal genetic counselling difficult.

Management for an individual with chronic mucocutaneous candidiasis consists of the following(relapse occurs once treatment is ceased, in many cases):

The cost of treatment depends on the amount of growth hormone given, which in turn depends on the child's weight and age. One year's worth of drugs normally costs about US $20,000 for a small child and over $50,000 for a teenager. These drugs are normally taken for five or more years.

Treatment can vary with severity of the infection. Moderate cases of Tinea Barbaea can be treated with topical antifungal medications. Topical antifungal medications will come in the form of cream, which can normally be obtained over the counter. More serious cases of Tinea Barbae warrant an oral antifungal medication.

By its enthusiasts, robot fetishism is more commonly referred to by the initials "ASFR". This initialism stems from the now-defunct Usenet newsgroup "alt.sex.fetish.robots". Many devotees of this fetish refer to themselves as technosexual, or as "ASFRians". ASFR can be divided into two distinct but sometimes overlapping types of fantasies.

The first of these is simply a desire to have a ready-made android partner. This partner can be desired for sex, companionship, or any combination of the two. The main distinguishing feature of this fantasy is that the android is a completely artificial construct, often manufactured solely to fulfil the wishes of its owner. This type of fantasy or situation is referred to as "built".

The second type of fantasy prevalent within ASFR is referred to as "transformation". This involves a human who has been either willingly or unwillingly turned into an android. That person can be either oneself or one's partner, or both. It is usually the process of transformation (through whatever means it is achieved) that is the focus of this fantasy.

Many people in the ASFR community prefer either one or the other. In some cases this preference is very strong, and people can be as equally repelled by one type as they are attracted to the other. In other cases, there is as much appreciation for built as there is for transformation. A recent informal survey of ASFR community members found that two thirds prefer built while the remainder prefer transformation or some combination of both.

The aspects of this fetish that are most appreciated by members of the ASFR community are greatly varied. For some, things like robotic appearance, motion, or sound are important for arousal. For others, these are not, and a completely lifelike android that appears to be human is desired. This holds true for other aspects, such as sentience or self-awareness. The ability of the android to remove parts of its skin or other bodily appendages in order to reveal its circuitry is quite pleasing to some, but distasteful to others. There is a further divide between those who prefer an android to appear human-like and those who would prefer a more mechanical looking robot, i.e. with a metallic surface.

As realistic androids and humanoid robots do not currently exist in a form readily available to the consumer, this fetish can only be acted upon in a limited number of ways. Primarily this is done through fantasy, involving either self stimulation or sexual roleplaying with a partner. ASFR art is therefore important to aid in the reinforcement of imagination.

Art with ASFR content includes but is not limited to science fiction movies, music videos, television shows, novels, short stories, illustrations, manipulated photographs, songs and even television commercials. Such works are sought after by technosexuals since economically viable androids are not yet available. Realistic sex dolls such as the RealDoll may provide a way to explore this fetish with existing technology. Recent developments in robotics and artificial intelligence, such as those seen in the Actroid or EveR-1 may lead to the production of more advanced synthetic partners.

It is also worth noting that some ASFRians do not wish to use synthetic partners at all, and instead would prefer human partners to participate in forms of fantasy play.

Robot fetishism (also ASFR or technosexuality) is a fetishistic attraction to humanoid robots; also to people acting like robots or people dressed in robot costumes. A less common fantasy involves transformation into a robot. In these ways it is similar to agalmatophilia, which involves attraction to or transformation into statues or mannequins.

Robot fetishism can be viewed as a form of erotic anthropomorphism. When transformation or roleplaying is involved it can be thought of as a form of erotic objectification.

Currently, there is no vaccine against human granulocytic anaplasmosis, so antibiotics are the only form of treatment. The best way to prevent HGA is to prevent getting tick bites.

Doxycycline is the treatment of choice. If anaplasmosis is suspected, treatment should not be delayed while waiting for a definitive laboratory confirmation, as prompt doxycycline therapy has been shown to improve outcomes. Presentation during early pregnancy can complicate treatment. Doxycycline compromises dental enamel during development. Although rifampin is indicated for post-delivery pediatric and some doxycycline-allergic patients, it is teratogenic. Rifampin is contraindicated during conception and pregnancy.

If the disease is not treated quickly, sometimes before the diagnosis, the person has a high chance of mortality. Most people make a complete recovery, though some people are intensively cared for after treatment. A reason for a person needing intensive care is if the person goes too long without seeing a doctor or being diagnosed. The majority of people, though, make a complete recovery with no residual damage.

Zoophilia is a paraphilia involving a sexual fixation on non-human animals. Bestiality is cross-species sexual activity between human and non-human animals. The terms are often used interchangeably, but some researchers make a distinction between the attraction (zoophilia) and the act (bestiality).

Although sex with animals is not outlawed in some countries, in most countries, bestiality is illegal under animal abuse laws or laws dealing with buggery or crimes against nature.

The decision to treat is based on a belief that the child will be disabled by being extremely short as an adult, so that the risks of treatment (including sudden death) will outweigh the risks of not treating the symptom of short stature. Although short children commonly report being teased about their height, most adults who are very short are not physically or psychologically disabled by their height. However, there is some evidence to suggest that there is an inverse linear relationship with height and with risk of suicide.

Treatment is expensive and requires many years of injections with human growth hormones. The result depends on the cause, but is typically an increase in final height of about taller than predicted. Thus, treatment takes a child who is expected to be much shorter than a typical adult and produces an adult who is still obviously shorter than average. For example, several years of successful treatment in a girl who is predicted to be as an adult may result in her being instead.

Increasing final height in children with short stature may be beneficial and could enhance health-related quality of life outcomes, barring troublesome side effects and excessive cost of treatments.

Most cases of HHV-6 infection get better on their own. If encephalitis occurs ganciclovir or foscarnet may be useful.

Cattle infested with bovine pediculosis are generally treated chemically, by drugs like ivermectin and cypermethrin.

Berserk llama syndrome or berserk male syndrome (as it is more pronounced in males) is a psychological condition suffered by human-raised llamas and alpacas that can cause them to exhibit dangerously aggressive behavior toward humans. The term has been overused, however, and is sometimes inappropriately applied to llamas with aggressive personalities that are not truly "berserk".

The condition is a result of the llama imprinting on its human handlers to such a degree that it considers them to be fellow llamas. Imprinting can be caused by bottle feeding and by isolation from other llamas. Adult male inter-llama interaction can be rough, including chest-ramming and biting, and they are strongly territorial. Male llamas suffering from this condition become dangerous when this behavior is directed toward humans and they usually have to be euthanised. Female llamas can also suffer from berserk llama syndrome but their behavior is usually limited to spitting and difficult handling.

Berserk llama syndrome can be prevented in males through castration before puberty.
