XX males are sterile due to low or no sperm content and there is currently no treatment to address this infertility. Genital ambiguities, while not necessary to treat for medical reasons, can be treated through the use of hormonal therapy, surgery, or both. Since XX male syndrome is variable in its presentation, the specifics of treatment varies widely as well. In some cases gonadal surgery can be performed to remove partial or whole female genitalia. This may be followed by plastic and reconstructive surgery to make the individual appear more externally male. Conversely, the individual may wish to become more feminine and feminizing genitoplasty can be performed to make the ambiguous genitalia appear more female. Hormonal therapy may also aid in making an individual appear more male or female.

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.

Biological treatments physically alter primary and secondary sex characteristics to reduce the discrepancy between an individual's physical body and gender identity. Biological treatments for GID without any form of psychotherapy is quite uncommon. Researchers have found that if individuals bypass psychotherapy in their GID treatment, they often feel lost and confused when their biological treatments are complete.

Psychotherapy, hormone replacement therapy, and sex reassignment surgery together can be effective treating GID when the WPATH standards of care are followed. The overall level of patient satisfaction with both psychological and biological treatments is very high.

There is no known cure available for the Wilson-Turner Syndrome. Instead, treatment options are available to fight individual symptoms. For obesity, a nutritional diet manipulation is combined with an exercise regimen that has a greater energy expenditure than intake. For hypogonadism, testosterone replacement is done. Finally, for gynecomastia, weight loss using similar methods for obesity is prescribed. However, if the individual finds his increased breast tissue psychologically distressing and/or is too severe, reduction mammaplasty is done. Currently, researchers are investigating therapy using antiestrogens and aromatase inhibitors to treat persistent pubertal gynecomastia.

Until the 1970s, psychotherapy was the primary treatment for gender dysphoria, and generally was directed to helping the person adjust to the gender of the physical characteristics present at birth. Psychotherapy is any therapeutic interaction that aims to treat a psychological problem. Though some clinicians still use only psychotherapy to treat gender dysphoria, it may now be used in addition to biological interventions. Psychotherapeutic treatment of GID involves helping the patient to adapt. Attempts to cure GID by changing the patient's gender identity to reflect birth characteristics have been ineffective.

The genetic variation is irreversible, however, individuals who want to look more masculine can take testosterone. Treating adolescents with implants of controlled release testosterone has shown good results when appropriately monitored. Hormone therapy is also useful in preventing the onset of osteoporosis.

Often individuals that have noticeable breast tissue or hypogonadism experience depression and/or social anxiety because they are outside of social norms. An academic term for this is psychosocial morbidity. At least one study indicates that planned and timed support should be provided for young men with Klinefelter syndrome to ameliorate current poor psychosocial outcomes. The surgical removal of the breasts may be considered for both the psychological reasons and to reduce the risk of breast cancer.

The use of behavioral therapy can mitigate any language disorders, difficulties at school and socialization. An approach by occupational therapy is useful in children, especially those who have dyspraxia.

Patients will generally need to be followed by an endocrinologist. If hypogonadism is present, testosterone treatment should be considered in all individuals regardless of cognitive abilities due to positive effects on bone health, muscle strength, fatigue, and endurance, with possible mental health/behavioral benefits as well.

Most children with XXYY will have some developmental delays and learning disabilities. Therefore the following aspects should be checked and monitored: psychology (cognitive and social–emotional development), speech/language therapy, occupational therapy, and physical therapy. Consultation with a developmental pediatrician, psychiatrist, or neurologist to develop a treatment plan including therapies, behavioral interventions, educational supports, and psychotropic medications for behavioral and psychiatric symptoms should be arranged.

Common diagnoses such as learning disability/ID, ADHD, autism spectrum disorders, mood disorders, tic disorders, and other mental health problems should be considered, screened for, and treated. Good responses to standard medication treatments for inattention, impulsivity, anxiety, and mood instability are seen in this group and such treatment can positively impact academic progress, emotional wellbeing and long-term outcome.

Poor fine motor coordination and the development of intention tremor can make handwriting slow and laborious, and occupational therapy and keyboarding should be introduced at an early age to facilitate schoolwork and self-help skills. Educational difficulties should be evaluated with a full psychological evaluation to identify discrepancies between verbal and performance skills and to identify individual academic needs. Expressive language skills are often affected throughout the lifespan and speech therapy interventions targeting expressive language skills, dyspraxia, and language pragmatics may be needed into adulthood. Adaptive skills (life skills) are a significant area of weakness necessitating community-based supports for almost all individuals in adulthood.

Additional treatment recommendations based on the individual strengths and weaknesses in XXYY syndrome may be required.

The treatment of genetic disorders is an ongoing battle with over 1800 gene therapy clinical trials having been completed, are ongoing, or have been approved worldwide. Despite this, most treatment options revolve around treating the symptoms of the disorders in an attempt to improve patient quality of life.

Gene therapy refers to a form of treatment where a healthy gene is introduced to a patient. This should alleviate the defect caused by a faulty gene or slow the progression of disease. A major obstacle has been the delivery of genes to the appropriate cell, tissue, and organ affected by the disorder. How does one introduce a gene into the potentially trillions of cells which carry the defective copy? This question has been the roadblock between understanding the genetic disorder and correcting the genetic disorder.

Because XLI is caused by a gene mutation or deletion, there is no "cure." One of the aims of treatment is to reduce scaling by removing the excess, flaky scales, and keep the skin hydrated. This can be achieved using a variety of topical creams.

- Keratolytic agents such as Ammonium lactate (Lac-Hydrin) are used to facilitate the release of retained corneocytes.

- Topical isotretinoin

- The topical receptor-selective retinoid tazarotene

Research is ongoing with regard to the use of gene therapy to treat XLI.

Treatments exist for the various symptoms associated with XXXY syndrome. Testosterone therapy, which is giving affected individuals doses of testosterone on a regular basis, has been shown to reduce aggressive behavior in these patients. But, this therapy has also been associated with negative side effects: worsening of behavior, and osteoporosis. Not all individuals are applicable for testosterone therapy, as the best results are often achieved when dosage begins at the initiation of puberty, and these individuals are often diagnosed at a later age, or not at all. Testosterone therapy has been shown to have no positive effect on fertility.

Consideration of the psychological phenotype of individuals with XXXY should be taken into account when treating these patients, because these traits affect compliance with treatments. When caught early, Taurodontism can be treated with a root canal and is often successful. Appropriate planning to avoid Taurodontism is possible, but this syndrome must be diagnosed early, which is not common. Taurodontism can often be detected as a symptom of XXXY syndrome before other characteristics develop, and can be an early indicator for it. Surgical treatments to correct joint problems, such as hip dysplasia are common, and are often successful alongside physiotherapy.

Those with XXXY syndrome can also attend speech therapy. This form of therapy helps patients to understand and produce more complex language. Those with XXXY syndrome tend to experience more severe speech delays, so this form of treatment can be very beneficial to them, and can help them to communicate better with other people.

Since hypotonia is common in those with this syndrome, physical therapy can also be helpful. This form of therapy may help these individuals develop muscle tone, and increase balance and coordination.

By 2010 over 100 successful pregnancies have been reported using IVF technology with surgically removed sperm material from males with Klinefelter syndrome. Microdissection testicular sperm extraction in adult men with Klinefelter syndrome reported success rates of up to 45%.

While there is no specific treatment for the underlying genetic cause of LFS; corrective procedures, preventive intervention measures and therapies may be considered in the treatment and management of the many craniofacial, orthopedic and psychiatric problems associated with the disorder. More pressing issues such as cardiac involvement or epileptic seizures should be routinely examined and monitored. Close attention and specialized follow-up care, including neuropshycological evaluation methods and therapies, and special education, should be given to diagnose and prevent psychiatric disorders and related behavioral problems such as psychosis and outbursts of aggression.

The FDA has approved one medication for the treatment of disorders of female libido, flibanserin.

There is no cure and no standard course of treatment for Coffin–Lowry syndrome. Treatment is symptomatic and supportive, and may include occupational, physical and speech therapy and educational services.

Not all genetic disorders directly result in death, however there are no known cures for genetic disorders. Many genetic disorders affect stages of development such as Down syndrome. While others result in purely physical symptoms such as muscular dystrophy. Other disorders, such as Huntington's disease show no signs until adulthood. During the active time of a genetic disorder, patients mostly rely on maintaining or slowing the degradation of quality of life and maintain patient autonomy. This includes physical therapy, pain management, and may include a selection of alternative medicine programs.

Upon diagnosis, estrogen and progesterone therapy is typically commenced, promoting the development of female characteristics.

The consequences of streak gonads to a person with Swyer syndrome:

1. Gonads cannot make estrogen, so the breasts will not develop and the uterus will not grow and menstruate until estrogen is administered. This is often given transdermally.

2. Gonads cannot make progesterone, so menstrual periods will not be predictable until progestin is administered, usually as a pill.

3. Gonads cannot produce eggs so conceiving children naturally is not possible. A woman with a uterus and ovaries but without female gamete is able to become pregnant by implantation of another woman's fertilized egg (embryo transfer).

4. Streak gonads with Y chromosome-containing cells have a high likelihood of developing cancer, especially gonadoblastoma. Streak gonads are usually removed within a year or so of diagnosis since the cancer can begin during infancy.

There exist some medications which can be useful specifically for treating sexual addiction.

Alternatively, doctors can prescribe general-purpose medications which have been found to be useful for a variety of behavioral addictions.

The term "pre-exposure prophylaxis" (PrEP) is generally used to refer to the use of [[antiviral drugs]] which can help in [[prevention of HIV/AIDS]]. PrEP is an optional treatment which may be taken by people who are HIV-negative, but who have substantial risk of getting an HIV infection.

In the US, most insurance plans cover these drugs.

In May 2013, the US FDA granted Orphan drug status to Diiodothyropropionic acid (DITPA) in the treatment of MCT8 deficiency. This was following the use of DITPA towards a child in Australia, under compassionate grounds.

There is no established treatment for AHDS. Theoretical considerations suggested TRIAC (triiodothyroacetate or tiratricol, a natural non-classical thyroid hormone) to be beneficial. In 2014, a case was demonstrated in which therapy with TRIAC in early childhood led to significant improvement of cognition and mobility. Currently, the effect of Triac is under investigation.

Therapeutic approaches for GIDC differ from those used on adults and have included behavior therapy, psychodynamic therapy, group therapy, and parent counseling. Proponents of this intervention seek to reduce gender dysphoria, make children more comfortable with their bodies, lessen ostracism, and reduce the child's psychiatric comorbidity. The majority of therapists currently employ these techniques. "Two short term goals have been discussed in the literature: the reduction or elimination of social ostracism and conflict, and the alleviation of underlying or associated psychopathology. Longer term goals have focused on the prevention of transsexualism and/or homosexuality."

Individual therapy with the child seeks to identify and resolve underlying factors, including familial factors; encourage identification by sex assigned at birth; and encourage same-sex friendships. Parent counseling involves setting limits on the child's cross-gender behavior; encouraging gender-neutral or sex-typical activities; examining familial factors; and examining parental factors such as psychopathology. Longtime researchers of gender identity disorder, Kenneth Zucker and Susan Bradley, state that it has been found that boys with gender identity disorder often have mothers who to an extent reinforced behavior more stereotypical of young girls. They also note that children with gender identity disorder tend to come from families where cross-gender role behavior was not explicitly discouraged. However, they also acknowledge that one could view these findings as merely indicative of the fact that parents who were more accepting of their child's cross-gender role behavior are also more likely to bring their children to a clinical psychiatrist as opposed to parents who are less accepting of cross-gender role behavior in their children (Bradley, Zucker, 1997). " Proponents acknowledge limited data on GIDC: "apart from a series of intrasubject behaviour therapy case reports from the 1970s, one will find not a single randomized controlled treatment trial in the literature" (Zucker 2001). Psychiatrist Domenico Di Ceglie opines that for therapeutic intervention, "efficacy is unclear," and psychologist Bernadette Wren says, "There is little evidence, however, that any psychological treatments have much effect in changing gender identity although some treatment centres continue to promote this as an aim (e.g. Zucker, & Bradley, 1995)." Zucker has stated that "the therapist must rely on the 'clinical wisdom' that has accumulated and to utilize largely untested case formulation conceptual models to inform treatment approaches and decisions."

Unlike Borjeson-Forssman-Lehmann syndrome, a disorder that was determined to be very similar to WTS, the individuals with Wilson–Turner syndrome do not develop cataracts or hypermetropia later in life. By far, the most debilitating part of this disorder is intellectual disability. Many of the other symptoms are more easily managed through hormone treatment, proper diet and exercise, and speech therapy.

XX females with lipoid CAH may need estrogen replacement at or after puberty. Active intervention has been used to preserve the possibility of fertility and conception in lipoid CAH females. In a case report in 2009, a woman with late onset lipoid CAH due to StAR deficiency underwent hormone replacement therapy in combination with an assisted fertility technique, intracytoplasmic sperm injection. This led to ovulation and with implantation of the in vitro fertilized egg, a successful birth.

At the present time, there is no specific treatment that can undo any chromosomal abnormality, nor the genetic pattern seen in people with idic(15). The extra chromosomal material in those affected was present at or shortly after conception, and its effects on brain development began taking place long before the child was born. Therapies are available to help address many of the symptoms associated with idic(15). Physical, occupational, and speech therapies along with special education techniques can stimulate children with idic(15) to develop to their full potential.

In terms of medical management of the symptoms associated with Chromosome 15q11.2-q13.1 Duplication Syndrome, families should be aware that individuals with chromosome 15 duplications may tolerate medications differently and may be more sensitive to side effects for some classes of medications, such as the serotonin reuptake inhibitor type medications (SSRI).

Thus, these should be used with caution and any new medication should be instituted in a controlled setting, with slow titration of levels and with a clear endpoint as to what the expected outcome for treatment is.

There is an increased risk of sudden, unexpected death among children and adults with this syndrome. The full cause is not yet understood but it is generally attributed to SUDEP (Sudden Unexplained Death in Epilepsy).

Standard treatment would include surgical exploration via laparotomy. Laparoscopy may be an option if the surgeon is particularly skilled in removing ovarian neoplasms via laparoscopy intact. If the diagnosis of gonadoblastoma is certain, a bilateral salpingo-oophorectomy (BSO) should be performed to remove both the primary tumor and the dysgenic contralateral ovary. If uninvolved, the uterus should be left intact. Modern reproductive endocrinology technology allows patients post BSO to achieve pregnancy via in-vitro fertilization (IVF) with a donor egg.

At puberty, most affected individuals require treatment with the male sex hormone testosterone to induce development of male secondary sex characteristics such as facial hair and deepening of the voice (masculinization). Hormone treatment can also help prevent breast enlargement (gynecomastia). Adults with this disorder are usually shorter than average for males and are unable to have children (infertile).
