The primary goals of hormone replacement are to protect from adrenal insufficiency and to suppress the excessive adrenal androgen production.

Glucocorticoids are provided to all children and adults with all but the mildest and latest-onset forms of CAH. The glucocorticoids provide a reliable substitute for cortisol, thereby reducing ACTH levels. Reducing ACTH also reduces the stimulus for continued hyperplasia and overproduction of androgens. In other words, glucocorticoid replacement is the primary method of reducing the excessive adrenal androgen production in both sexes. A number of glucocorticoids are available for therapeutic use. Hydrocortisone or liquid prednisolone is preferred in infancy and childhood, and prednisone or dexamethasone are often more convenient for adults.

The glucocorticoid dose is typically started at the low end of physiologic replacement (6–12 mg/m²) but is adjusted throughout childhood to prevent both growth suppression from too much glucocorticoid and androgen escape from too little. Serum levels of 17α-hydroxyprogesterone, testosterone, androstenedione, and other adrenal steroids are followed for additional information, but may not be entirely normalized even with optimal treatment. ("See Glucocorticoid for more on this topic.")

Mineralocorticoids are replaced in all infants with salt-wasting and in most patients with elevated renin levels. Fludrocortisone is the only pharmaceutically available mineralocorticoid and is usually used in doses of 0.05 to 2 mg daily. Electrolytes, renin, and blood pressure levels are followed to optimize the dose.

One possible treatment is with anastrozole. Histrelin acetate (Supprelin LA), triptorelin or leuprolide, any GnRH agonists, may be used. Non-continuous usage of GnRH agonists stimulates the pituitary gland to release follicle stimulating hormone (FSH) and luteinizing hormone (LH). However, when used regularly, GnRH agonists cause a decreased release of FSH and LH. Prolonged use has a risk of causing osteoporosis. After stopping GnRH agonists, pubertal changes resume within 3 to 12 months.

Even after diagnosis and initiation of treatment, a small percentage of children and adults with infancy or childhood onset CAH die of adrenal crisis. Deaths from this are entirely avoidable if the child and family understand that the daily glucocorticoids cannot be allowed to be interrupted by an illness. When a person is well, missing a dose, or even several doses, may produce little in the way of immediate symptoms. However, glucocorticoid needs are increased during illness and stress, and missed doses during an illness such as the "flu" (or viral gastroenteritis) can lead within hours to reduced blood pressure, shock, and death.

To prevent this, all persons taking replacement glucocorticoids are taught to increase their doses in the event of illness, surgery, severe injury, or severe exhaustion. More importantly, they are taught that vomiting warrants an injection within hours of hydrocortisone (e.g., SoluCortef) or other glucocorticoid. This recommendation applies to both children and adults. Because young children are more susceptible to vomiting illnesses than adults, pediatric endocrinologists usually teach parents how to give hydrocortisone injections.

As an additional precaution, persons with adrenal insufficiency are advised to wear a medical identification tag or carry a wallet card to alert those who may be providing emergency medical care of the urgent need for glucocorticoids.

Treatment of hyperandrogenism varies with the underlying condition that causes it. As a hormonal symptom of polycystic ovary syndrome, menopause, and other endocrine disorders, it is primarily treated as a symptom of these disorders. Systemically, it is treated with antiandrogens such as cyproterone acetate, flutamide and spironolactone to control the androgen levels in the patient's body. For Hyperandrogenism caused by Late-Onset Congenital Adrenal Hyperplasia (CAH), treatment is primarily focused on providing the patient with Glucocorticoids to combat the low cortisol production and the corresponding increase in androgens caused by the swelling of the Adrenal Glands. Oestrogen-based oral contraceptives are used to treat both CAH and PCOS caused hyperandrogenism. These hormonal treatments have been found to reduce the androgen excess and suppress adrenal androgen production and cause a significant decrease in hirsutism.

Hyperandrogenism is often managed symptomatically. Hirsutism and acne both respond well to the hormonal treatments described above, with 60-100% reporting an improvement in hirsutism. Androgenic alopecia however, does not show a significant improvement with hormonal treatments and requires other treatments, such as hair transplantation.

The caloric intake of children with SRS must be carefully controlled in order to provide the best opportunity for growth. If the child is unable to tolerate oral feeding, then enteral feeding may be used, such as the percutaneous endoscopic gastrostomy.

In children with limb-length differences or scoliosis, physiotherapy can alleviate the problems caused by these symptoms. In more severe cases, surgery to lengthen limbs may be required. To prevent aggravating posture difficulties children with leg length differences may require a raise in their shoe.

Growth hormone therapy is often prescribed as part of the treatment of SRS. The hormones are given by injection typically daily from the age of 2 years old through teenage years. It may be effective even when the patient does not have a growth hormone deficiency. Growth hormone therapy has been shown to increase the rate of growth in patients and consequently prompts 'catch up' growth. This may enable the child to begin their education at a normal height, improving their self-esteem and interaction with other children. The effect of growth hormone therapy on mature and final height is as yet uncertain. There are some theories suggesting that the therapy also assists with muscular development and managing hypoglycemia.

Treatment of all forms of CAH may include any of:

1. supplying enough glucocorticoid to reduce hyperplasia and overproduction of androgens or mineralocorticoids

2. providing replacement mineralocorticoid and extra salt if the person is deficient

3. providing replacement testosterone or estrogen at puberty if the person is deficient

4. additional treatments to optimize growth by delaying puberty or delaying bone maturation

All of these management issues are discussed in more detail in congenital adrenal hyperplasia due to 21-hydroxylase deficiency.

Dexamethasone is used as an off-label early pre-natal treatment for the symptoms of CAH in female fetuses, but it does not treat the underlying congenital disorder. A 2007 Swedish clinical trial found that treatment may cause cognitive and behavioural defects, but the small number of test subjects means the study cannot be considered definitive. A 2012 American study found no negative short term outcomes, but "lower cognitive processing in CAH girls and women with long-term DEX exposure." Administration of pre-natal dexamethasone has been the subject of controversy over issues of informed consent and because treatment must predate a clinical diagnosis of CAH in the female fetus, especially because in utero dexamethasone may cause metabolic problems that are not evident until later in life; Swedish clinics ceased recruitment for research in 2010.

The treatment has also raised concerns in LGBT and bioethics communities following publication of an essay posted to the forum of the Hastings Center, and research in the Journal of Bioethical Inquiry, which found that pre-natal treatment of female fetuses was suggested to prevent those fetuses from becoming lesbians after birth, may make them more likely to engage in "traditionally" female-identified behaviour and careers, and more interested in bearing and raising children. Citing a known attempt by a man using his knowledge of the fraternal birth order effect to avoid having a homosexual son by using a surrogate, the essayists (Professor Alice Dreger of Northwestern University's Feinberg School of Medicine, Professor Ellen Feder of American University and attorney Anne Tamar-Mattis) suggest that pre-natal "dex" treatments constitute the first known attempt to use "in utero" protocols to reduce the incidence of homosexuality and bisexuality in humans. Research on the use of prenatal hormone treatments to prevent homosexuality stretches back to the early 1990s or earlier.

Since CAH is a recessive gene, both the mother and father must be recessive carriers of CAH for a child to have CAH. Due to advances in modern medicine, those couples with the recessive CAH genes have an option to prevent CAH in their offspring through preimplantation genetic diagnosis (PGD). In PGD, the egg is fertilized outside the women's body in a petri dish (IVF). On the 3rd day, when the embryo has developed from one cell to about 4 to 6 cells, one of those cells is removed from the embryo without harming the embryo. The embryo continues to grow until day 5 when it is either frozen or implanted into the mother. Meanwhile, the removed cell is analyzed to determine if the embryo has CAH. If the embryo is determined to have CAH, the parents may make a decision as to whether they wish to have it implanted in the mother or not.

Meta-analysis of the studies supporting the use of dexamethasone on CAH at-risk fetuses found "less than one half of one percent of published 'studies' of this intervention were regarded as being of high enough quality to provide meaningful data for a meta-analysis. Even these four studies were of low quality" ... "in ways so slipshod as to breach professional standards of medical ethics" and "there were no data on long-term follow-up of physical and metabolic outcomes in children exposed to dexamethasone".

Since risk factors are not known and vary among individuals with hyperandrogegism, there is no sure method to prevent this medical condition. Therefore, more longterm studies are needed first to find a cause for the condition before being able to find a sufficient method of prevention.

However, there are a few things that can help avoid long-term medical issues related to hyperandrogenism like PCOS. Getting checked by a medical professional for hyperandrogenism; especially if one has a family history of the condition, irregular periods, or diabetes; can be beneficial. Watching your weight and diet is also important in decreasing your chances, especially in obese females, since continued exercise and maintaining a healthy diet leads to an improved menstrual cycle as well as to decreased insulin levels and androgen concentrations.

Hormonal suppressive therapy with luteinizing hormone receptor agonists like leuprolide can be used to treat the seizure component, and are effective in most patients.

Surgery is offered if there is failure of medical therapy or rapid growth of lesion, with specific options including stereotactic thermocoagulation, gamma knife radiosurgery, and physical resection by transsphenoidal microsurgery. Surgical response is typically better when the seizure focus has been found by EEG to originate in or near the mass. The specific location of the lesion relative to the pituitary and infundibulum and the amount of hormonal disturbance at presentation can help predict risk of hypopituitarism following surgery.

Recent research has been directed towards finding better treatment options. Multi-drug therapy using insulin sensitizers, such as metformin and pioglitazone, has been linked to improving residual insulin action. High doses of insulin-like growth factor 1 has also been effective in patients with Rabson–Mendenhall syndrome. Future studies are also focusing on the relation between genotype and phenotype. Though there is no cure, researchers remain optimistic on finding a cure.

There is no known cure for Rabson–Mendenhall syndrome. However, a series of steps can be directed towards treating the specific symptoms. For example, surgery may be performed to treat dental abnormalities. Furthermore, the goal of the treatment is also to maintain blood glucose levels as constantly as possible. Insulin is not as effective at normal doses, and even large doses show minimal effects. Frequent feeding is the most effective treatment to control blood glucose levels. Well thought out meals with complex combinations of carbohydrates are put together and assigned to the patient in hope of seeing a constant glucose level maintained. Though effective, these treatments tend to show more of an impact initially, and can become ineffective within months.

Treatment of Rabson–Mendenhall syndrome with pharmacologic doses of human leptin may result in improvement of fasting hyperglycemia, hyperinsulinemia, basal glucose, and glucose and insulin tolerance.

Quality of life is impacted severely and the prognosis of patients with Rabson–Mendenhall syndrome remains poor. This is due to the lack of a long term treatment. Life expectancy is 1–2 years.

Several treatments have been found to be effective in managing AES, including aromatase inhibitors and gonadotropin-releasing hormone analogues in both sexes, androgen replacement therapy with non-aromatizable androgens such as DHT in males, and progestogens (which, by virtue of their antigonadotropic properties at high doses, suppress estrogen levels) in females. In addition, male patients often seek bilateral mastectomy, whereas females may opt for breast reduction if warranted.

Medical treatment of AES is not absolutely necessary, but it is recommended as the condition, if left untreated, may lead to excessively large breasts (which may necessitate surgical reduction), problems with fertility, and an increased risk of endometriosis and estrogen-dependent cancers such as breast and endometrial cancers later in life. At least one case of male breast cancer has been reported.

The syndrome usually responds well to thyroid hormone replacement with complete resolution of symptoms.

There are no cures for FHS. Close monitoring of growth in the first few years is essential, as well as annual general health screening and tests listed below. An FHS diagnosis will affect the individual and those there to support them.

Managing symptoms and features of FHS involves maintaining a close watch on the patient's physical as well as mental health. This would include:

- Sequencing of SRCAP exons 31–34 in all suspected cases

- Complete assessments of auditory and visual systems

- Renal and urinary tract ultrasound

- Orthopedic assessment of hip dysplasia and clavicle abnormalities

- Neurologic assessment if there is a suspicion of seizures

- Dental hygiene to prevent cavities and to monitor for malocclusion

- Evaluation for growth hormone deficiency at baseline, to be repeated if loss of growth velocity occurs

- Monitoring of bone age and pubertal timing in case of precocious puberty

- Psychoeducational assessments corrected for deficiencies in expressive language and sensory issues

- Monitoring of behavioral disturbances and provision of early intervention

- Counseling for families regarding recurrence risk and the offspring of individuals with FHS

Special education programs and vocational training to address developmental disabilities are highly recommended, as well as communication rehabilitation with sign language or alternative means of communication. Behavior management strategies could also include referrals to behavior specialists or psychologists for help. For those concerned, genetic counseling can be sought for issues related to testing of at-risk relatives.

Many of the congenital malformations found with Malpuech syndrome can be corrected surgically. These include cleft lip and palate, omphalocele, urogenital and craniofacial abnormalities, skeletal deformities such as a caudal appendage or scoliosis, and hernias of the umbillicus. The primary area of concern for these procedures applied to a neonate with congenital disorders including Malpuech syndrome regards the logistics of anesthesia. Methods like tracheal intubation for management of the airway during general anesthesia can be hampered by the even smaller, or maldeveloped mouth of the infant. For regional anesthesia, methods like spinal blocking are more difficult where scoliosis is present. In a 2010 report by Kiernan et al., a four-year-old girl with Malpuech syndrome was being prepared for an unrelated tonsillectomy and adenoidectomy. While undergoing intubation, insertion of a laryngoscope, needed to identify the airway for the placement of the endotracheal tube, was made troublesome by the presence of micrognathia attributed to the syndrome. After replacement with a laryngoscope of adjusted size, intubation proceeded normally. Successful general anesthesia followed.

A rare follow-up of a male with Malpuech syndrome was presented by Priolo et al. (2007). Born at term from an uneventful pregnancy and delivery, the infant underwent a surgical repair of a cleft lip and palate. No problems were reported with the procedure. A heart abnormality, atrial septal defect, was also apparent but required no intervention. At age three years, mental retardation, hyperactivity and obsessive compulsive disorder were diagnosed; hearing impairment was diagnosed at age six, managed with the use of hearing aids. Over the course of the decade that followed, a number of psychiatric evaluations were performed. At age 14, he exhibited a fear of physical contact; at age 15, he experienced a severe psychotic episode, characterized by agitation and a loss of sociosexual inhibition. This array of symptoms were treated pharmocologically (with prescription medications). He maintained a low level of mental deficiency by age 17, with moments of compulsive echolalia.

Van Wyk and Grumbach syndrome is a medical condition defined by a combination of hypothyroidism, precocious puberty (usually with delayed bone age) and ovarian cysts in pre- and post-pubertal girls.

Familial male-limited precocious puberty, often abbreviated as FMPP, also known as familial sexual precocity or gonadotropin-independent testotoxicosis, is a form of gonadotropin-independent precocious puberty in which boys experience early onset and progression of puberty. Signs of puberty can develop as early as an age of 1 year.

The spinal length in boys may be short due to a rapid advance in epiphyseal maturation. It is an autosomal dominant condition with a mutation of the luteinizing hormone (LH) receptor. Treatment is with drugs that suppress gonadal steroidogenesis, such as cyproterone acetate, ketoconazole, spironolactone, and testolactone. Alternatively, the combination of the androgen receptor antagonist bicalutamide and the aromatase inhibitor anastrozole may be used.

McCune–Albright syndrome is a complex genetic disorder affecting the bone, skin, and endocrine systems. It is a mosaic disease arising from somatic activating mutations in "GNAS", which encodes the alpha-subunit of the Gs G-coupled protein receptor. These mutations lead to constitutive receptor activation.

It was first described in 1937 by Donovan James McCune and Fuller Albright.

Hypergonadism is a condition where there is a hyperfunction of the gonads. It can manifest as precocious puberty, and is caused by abnormally high levels of testosterone or estrogen, crucial hormones for sexual development. In some cases, it may be caused by a tumor, which can be malignant but mostly benign. Anabolic steroids may also be a major cause of high androgen and/or estrogen functional activity. Symptoms of the condition may include precocious puberty, rapid growth in adolescents, high libido, acne, excessive hairiness, and others.

The only curative treatment is complete surgical excision of the tumor, which can be performed even in the case of invasion into large blood vessels, such as the renal vein or inferior vena cava. The 5-year survival rate after successful surgery is 50–60%, but unfortunately, a large percentage of patients are not surgical candidates. Radiation therapy and radiofrequency ablation may be used for palliation in patients who are not surgical candidates.

Chemotherapy regimens typically include the drug mitotane, an inhibitor of steroid synthesis which is toxic to cells of the adrenal cortex, as well as standard cytotoxic drugs. A retrospective analysis showed a survival benefit for mitotane in addition to surgery when compared to surgery alone.

The two most common regimens are cisplatin, doxorubicin, etoposide + mitotane and streptozotocin + mitotane. It is unknown which regimen is better. Researchers at Uppsala University Hospital initiated a collaboration between adrenocortical cancer specialists in Europe, USA and Australia, to conduct the first ever randomized controlled trial in adrenocortical cancer (FIRM-ACT study), comparing these two regimens.

In medicine, precocious puberty is puberty occurring at an unusually early age. In most cases, the process is normal in every aspect except the unusually early age, and simply represents a variation of normal development. In a minority of children, the early development is triggered by a disease such as a tumor or injury of the brain. Even when there is no disease, unusually early puberty can have adverse effects on social behavior and psychological development, can reduce adult height potential, and may shift some lifelong health risks. Central precocious puberty can be treated by suppressing the pituitary hormones that induce sex steroid production. The opposite condition is delayed puberty.

The term is used with several slightly different meanings that are usually apparent from the context. In its broadest sense, and often simplified as early puberty, "precocious puberty" sometimes refers to any physical sex hormone effect, due to any cause, occurring earlier than the usual age, especially when it is being considered as a medical problem. Stricter definitions of "precocity" may refer only to central puberty starting before a statistically specified age based on percentile in the population (e.g., 2.5 standard deviations below the population mean), on expert recommendations of ages at which there is more than a negligible chance of discovering an abnormal cause, or based on opinion as to the age at which early puberty may have adverse effects. A common definition for medical purposes is onset before 8 years in girls or 9 years in boys.

McCune–Albright syndrome is suspected when two or more of the following features are present:

- Hyperfunctioning endocrine disease (gonadotropin independent precocious puberty, hyperthyroidism, growth hormone excess, neonatal Cushing syndrome)

- Fibrous dysplasia

- Café au lait macules

Patients may have one or many of these features, which may occur in any combination.

The clinical presentation varies greatly depending on the disease features. Patients with fibrous dysplasia may have bone fractures, pain, and deformities.

Cafe-au-lait skin macules tend to have characteristic features, including jagged "coast of Maine" borders, and location respecting the midline of the body.

Endocrine disease in McCune–Albright syndrome results from increased hormone production. The most common endocrinopathy is precocious puberty, which presents in girls with recurrent estrogen-producing cysts leading to episodic breast development, growth acceleration, and vaginal bleeding. Precocious puberty may also occur in boys with McCune–Albright syndrome, but is much less common. Additional potential endocrinopathies include hyperthyroidism and growth hormone excess. Cushing syndrome is a very rare feature that develops only in infancy. Patients with polyostotic fibrous dysplasia may develop low blood phosphate levels due to overproduction of the hormone fibroblast growth factor-23.

McCune–Albright syndrome has different levels of severity. For example, one child with McCune–Albright syndrome may be entirely healthy, with no outward evidence of bone or endocrine problems, enter puberty at close to the normal age, and have no unusual skin pigmentation. Diagnosis may be made only after decades. In other cases, children are diagnosed in early infancy, show obvious bone disease, and obvious increased endocrine secretions from several glands.

An androgen-dependent condition, disease, disorder, or syndrome, is a medical condition that is, in part or full, dependent on, or is sensitive to, the presence of androgenic activity in the body.

Known androgen-dependent conditions include acne, seborrhea, androgenic alopecia, hirsutism, hidradenitis suppurativa, precocious puberty in boys, hypersexuality, paraphilias, benign prostatic hyperplasia (BPH), prostate cancer, and hyperandrogenism in women such as in polycystic ovary syndrome (PCOS).

Such conditions may be treated with drugs with antiandrogen actions, including androgen receptor antagonists such as cyproterone acetate, spironolactone, and bicalutamide, 5α-reductase inhibitors such as finasteride and dutasteride, CYP17A1 inhibitors such as abiraterone acetate, gonadotropin-releasing hormone (GnRH) analogues such as leuprolide and cetrorelix, and/or other antigonadotropins such as megestrol acetate and medroxyprogesterone acetate.

Congenital adrenal hyperplasia (CAH) are any of several autosomal recessive diseases resulting from mutations of genes for enzymes mediating the biochemical steps of production of mineralocorticoids, glucocorticoids or sex steroids from cholesterol by the adrenal glands (steroidogenesis).

Most of these conditions involve excessive or deficient production of sex steroids and can alter development of primary or secondary sex characteristics in some affected infants, children, or adults.

There is no cure for ONH; however, many therapeutic interventions exist for the care of its symptoms. These may include hormone replacement therapy for hypopituitarism, occupational, physical, and/or speech therapy for other issues, and services of a teacher of students with blindness/visually impairment. Special attention should be paid to early development of oral motor skills and acclimation to textured foods for children with texture aversion, or who are otherwise resistant to eating.

Sleep dysfunction can be ameliorated using melatonin in the evening in order to adjust a child's circadian clock.

Treatment for strabismus may include patching of the better eye, which may result in improved vision in the worse eye; however, this should be reserved for cases in which the potential for vision improvement in both eyes is felt to be good. Surgery to align the eyes can be performed once children with strabismus develop equal visual acuity in both eyes, most often after the age of three. Generally surgery results in improved appearance only and not in improved visual function.

An inborn error of steroid metabolism is an inborn error of metabolism due to defects in steroid metabolism.

A variety of conditions of abnormal steroidogenesis exist due to genetic mutations in the steroidogenic enzymes involved in the process, of which include:

- 18,20-Desmolase (P450scc) deficiency: blocks production of all steroid hormones from cholesterol

- 3β-Hydroxysteroid dehydrogenase type 2 deficiency: impairs progestogen and androgen metabolism; prevents the synthesis of estrogens, glucocorticoids, and mineralocorticoids; causes androgen deficiency in males and androgen excess in females

- Combined 17α-hydroxylase/17,20-lyase deficiency: impairs progestogen metabolism; prevents androgen, estrogen, and glucocorticoid synthesis; causes mineralocorticoid excess

- Isolated 17,20-lyase deficiency: prevents androgen and estrogen synthesis

- 21-Hydroxylase deficiency: prevents glucocorticoid and mineralocorticoid synthesis; causes androgen excess in females

- 11β-Hydroxylase type 1 deficiency: impairs glucocorticoid and mineralocorticoid metabolism; causes glucocorticoid deficiency and mineralocorticoid excess as well as androgen excess in females

- 11β-Hydroxylase type 2 deficiency: impairs corticosteroid metabolism; results in excessive mineralocorticoid activity

- 18-Hydroxylase deficiency: impairs mineralocorticoid metabolism; results in mineralocorticoid deficiency

- 18-Hydroxylase overactivity: impairs mineralocorticoid metabolism; results in mineralocorticoid excess

- 17β-Hydroxysteroid dehydrogenase deficiency: impairs androgen and estrogen metabolism; results in androgen deficiency in males and androgen excess and estrogen deficiency in females

- 5α-Reductase type 2 deficiency: prevents the conversion of testosterone to dihydrotestosterone; causes androgen deficiency in males

- Aromatase deficiency: prevents estrogen synthesis; causes androgen excess in females

- Aromatase excess: causes excessive conversion of androgens to estrogens; results in estrogen excess in both sexes and androgen deficiency in males

In addition, several conditions of abnormal steroidogenesis due to genetic mutations in "receptors", as opposed to enzymes, also exist, including:

- Gonadotropin-releasing hormone (GnRH) insensitivity: prevents synthesis of sex steroids by the gonads in both sexes

- Follicle-stimulating (FSH) hormone insensitivity: prevents synthesis of sex steroids by the gonads in females; merely causes problems with fertility in males

- Luteinizing hormone (LH) insensitivity: prevents synthesis of sex steroids by the gonads in males; merely causes problems with fertility in females

- Luteinizing hormone (LH) oversensitivity: causes androgen excess in males, resulting in precocious puberty; females are asymptomatic

No activating mutations of the GnRH receptor in humans have been described in the medical literature, and only one of the FSH receptor has been described, which presented as asymptomatic.
