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.

Pituitary tumors require treatment when they are causing specific symptoms, such as headaches, visual field defects or excessive hormone secretion. Transsphenoidal surgery (removal of the tumor by an operation through the nose and the sphenoidal sinuses) may, apart from addressing symptoms related to the tumor, also improve pituitary function, although the gland is sometimes damaged further as a result of the surgery. When the tumor is removed by craniotomy (opening the skull), recovery is less likely–but sometimes this is the only suitable way to approach the tumor. After surgery, it may take some time for hormone levels to change significantly. Retesting the pituitary hormone levels is therefore performed 2 to 3 months later.

Prolactinomas may respond to dopamine agonist treatment–medication that mimics the action of dopamine on the lactrotrope cells, usually bromocriptine or cabergoline. This approach may improve pituitary hormone secretion in more than half the cases, and make supplementary treatment unnecessary.

Other specific underlying causes are treated as normally. For example, hemochromatosis is treated by venesection, the regular removal of a fixed amount of blood. Eventually, this decreases the iron levels in the body and improves the function of the organs in which iron has accumulated.

The primary current medical treatment of acromegaly is to use somatostatin analogues – octreotide (Sandostatin) or lanreotide (Somatuline).

These somatostatin analogues are synthetic forms of a brain hormone, somatostatin, which stops GH production. The long-acting forms of these drugs must be injected every 2 to 4 weeks for effective treatment. Most patients with acromegaly respond to this medication. In many patients, GH levels fall within one hour and headaches improve within minutes after the injection. Octreotide and lanreotide are effective for long-term treatment. Octreotide and lanreotide have also been used successfully to treat patients with acromegaly caused by non-pituitary tumors.

Somatostatin analogues are also sometimes used to shrink large tumors before surgery.

Because octreotide inhibits gastrointestinal and pancreatic function, long-term use causes digestive problems such as loose stools, nausea, and gas in one third of patients. In addition, approximately 25 percent of patients develop gallstones, which are usually asymptomatic. In some cases, octreotide treatment can cause diabetes due to the fact that somatostatin and its analogues can inhibit the release of insulin.

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".

Most pituitary hormones can be replaced indirectly by administering the products of the effector glands: hydrocortisone (cortisol) for adrenal insufficiency, levothyroxine for hypothyroidism, testosterone for male hypogonadism, and estradiol for female hypogonadism (usually with a progestogen to inhibit unwanted effects on the uterus). Growth hormone is available in synthetic form, but needs to be administered parenterally (by injection). Antidiuretic hormone can be replaced by desmopressin (DDAVP) tablets or nose spray. Generally, the lowest dose of the replacement medication is used to restore wellbeing and correct the deranged results, as excessive doses would cause side-effects or complications. Those requiring hydrocortisone are usually instructed to increase their dose in physically stressful events such as injury, hospitalization and dental work as these are times when the normal supplementary dose may be inadequate, putting the patient at risk of adrenal crisis.

Long-term follow up by specialists in endocrinology is generally needed for people with known hypopituitarism. Apart from ensuring the right treatment is being used and at the right doses, this also provides an opportunity to deal with new symptoms and to address complications of treatment.

Difficult situations arise in deficiencies of the hypothalamus-pituitary-gonadal axis in people (both men and women) who experience infertility; infertility in hypopituitarism may be treated with subcutaneous infusions of FSH, human chorionic gonadotropin–which mimics the action of LH–and occasionally GnRH.

For those who are unresponsive to somatostatin analogues, or for whom they are otherwise contraindicated, it is possible to treat using one of the dopamine agonists, bromocriptine or cabergoline. As tablets rather than injections, they cost considerably less. These drugs can also be used as an adjunct to somatostatin analogue therapy. They are most effective in those whose pituitary tumours cosecrete prolactin. Side effects of these dopamine agonists include gastrointestinal upset, nausea, vomiting, light-headedness when standing, and nasal congestion. These side effects can be reduced or eliminated if medication is started at a very low dose at bedtime, taken with food, and gradually increased to the full therapeutic dose. However, bromocriptine lowers GH and IGF-1 levels and reduces tumor size in fewer than half of patients with acromegaly. Some patients report improvement in their symptoms although their GH and IGF-1 levels still are elevated.

Management of salt-wasting crises and mineralocorticoid treatment are as for other forms of salt-wasting congenital adrenal hyperplasias: saline and fludrocortisone.

Glucocorticoids can be provided at minimal replacement doses because there is no need for suppression of excessive adrenal androgens or mineralocorticoids. As with other forms of adrenal insufficiency, extra glucocorticoid is needed for stress coverage.

Life long hormone replacement therapy for the hormones that are missing.

Treatment of HH may consist of administration of either a GnRH agonist or a gonadotropin formulation in the case of primary HH and treatment of the root cause (e.g., a tumor) of the symptoms in the case of secondary HH. Alternatively, hormone replacement therapy with androgens and estrogens in males and females, respectively, may be employed.

Hypertension and mineralocorticoid excess is treated with glucocorticoid replacement, as in other forms of CAH.

Most genetic females with both forms of the deficiency will need replacement estrogen to induce puberty. Most will also need periodic progestin to regularize menses. Fertility is usually reduced because egg maturation and ovulation is poorly supported by the reduced intra-ovarian steroid production.

The most difficult management decisions are posed by the more ambiguous genetic (XY) males. Most who are severely undervirilized, looking more female than male, are raised as females with surgical removal of the nonfunctional testes. If raised as males, a brief course of testosterone can be given in infancy to induce growth of the penis. Surgery may be able to repair the hypospadias. The testes should be salvaged by orchiopexy if possible. Testosterone must be replaced in order for puberty to occur and continued throughout adult life.

GH treatment is not recommended for children who are not growing despite having normal levels of growth hormone, and in the UK it is not licensed for this use. Children requiring treatment usually receive daily injections of growth hormone. Most pediatric endocrinologists monitor growth and adjust dose every 3–6 months and many of these visits involve blood tests and x-rays. Treatment is usually extended as long as the child is growing, and lifelong continuation may be recommended for those most severely deficient. Nearly painless insulin syringes, pen injectors, or a needle-free delivery system reduce the discomfort. Injection sites include the biceps, thigh, buttocks, and stomach. Injection sites should be rotated daily to avoid lipoatrophy. Treatment is expensive, costing as much as US $10,000 to $40,000 a year in the USA.

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.

Treatment of HH is usually with hormone replacement therapy, consisting of androgen and estrogen administration in males and females, respectively.

Standard therapy involves intravenous injections of glucocorticoids and large volumes of intravenous saline solution with dextrose (glucose). This treatment usually brings rapid improvement. If intravenous access is not immediately available, intramuscular injection of glucocorticoids can be used. When the patient can take fluids and medications by mouth, the amount of glucocorticoids is decreased until a maintenance dose is reached. If aldosterone is deficient, maintenance therapy also includes oral doses of fludrocortisone acetate.

Treatment for Addison's disease involves replacing the missing cortisol, sometimes in the form of hydrocortisone tablets, or prednisone tablets in a dosing regimen that mimics the physiological concentrations of cortisol. Alternatively, one-quarter as much prednisolone may be used for equal glucocorticoid effect as hydrocortisone. Treatment is usually lifelong. In addition, many patients require fludrocortisone as replacement for the missing aldosterone.

People with Addison's are often advised to carry information on them (e.g., in the form of a MedicAlert bracelet or information card) for the attention of emergency medical services personnel who might need to attend to their needs. It is also recommended that a needle, syringe, and injectable form of cortisol be carried for emergencies. People with Addison's disease are advised to increase their medication during periods of illness or when undergoing surgery or dental treatment. Immediate medical attention is needed when severe infections, vomiting, or diarrhea occur, as these conditions can precipitate an Addisonian crisis. A patient who is vomiting may require injections of hydrocortisone instead.

GH deficiency is treated by replacing GH with daily injections under the skin or into muscle. Until 1985, growth hormone for treatment was obtained by extraction from human pituitary glands collected at autopsy. Since 1985, recombinant human growth hormone (rHGH) is a recombinant form of human GH produced by genetically engineered bacteria, manufactured by recombinant DNA technology. In both children and adults, costs of treatment in terms of money, effort, and the impact on day-to-day life, are substantial.

Treatment is directed towards (1) correcting hypotension, hypovolemia, electrolyte imbalances, and metabolic acidosis; (2) improving vascular integrity, and (3) providing an immediate source of glucocorticoids. Rapid correction of hypovolemia is the first priority.

Most patients show dramatic improvement within 24 to 48 hours of appropriate fluid and glucocorticoid therapy. Over the ensuing 2 to 4 days, a gradual transition from IV fluids to oral water and food is undertaken, and maintenance mineralocorticoid and glucocorticoid therapy is initiated. Failure to make this transition smoothly should raise suspicion of insufficient glucocorticoid supplementation, concurrent endocrinopathy (e.g. hypothyroidism), or cocurrent illness (especially renal damage).

After diagnosis, it is important for patients to be continually monitored. The most common treatment for PPNAD is bilateral laparoscopic adrenalectomy; the process by which both adrenal glands are removed by a small incision.

Patients who have received this treatment will be prescribed mineralocorticoid and glucocorticoid steroids as they are no longer being naturally produced.

This is a treatment which has been used and refined since 1984.

Males and females may be treated with hormone replacement therapy (i.e., with androgens and estrogens, respectively), which will result in normal sexual development and resolve most symptoms. In the case of 46,XY (genetically male) individuals who are phenotypically female and/or identify as the female gender, they should be treated with estrogens instead. Removal of the undescended testes should be performed in 46,XY females to prevent their malignant degeneration, whereas in 46,XY males surgical correction of the genitals is generally required, and, if necessary, an orchidopexy (relocation of the undescended testes to the scrotum) may be performed as well. Namely in genetic females presenting with ovarian cysts, GnRH analogues may be used to control high FSH and LH levels if they are unresponsive to estrogens.

Most Cushing's syndrome cases are caused by corticosteroid medications, such as those used for asthma, arthritis, eczema and other inflammatory conditions. Consequently, most patients are effectively treated by carefully tapering off (and eventually stopping) the medication that causes the symptoms.

If an adrenal adenoma is identified, it may be removed by surgery. An ACTH-secreting corticotrophic pituitary adenoma should be removed after diagnosis. Regardless of the adenoma's location, most patients require steroid replacement postoperatively at least in the interim, as long-term suppression of pituitary ACTH and normal adrenal tissue does not recover immediately. Clearly, if both adrenals are removed, replacement with hydrocortisone or prednisolone is imperative.

In those patients not suited for or unwilling to undergo surgery, several drugs have been found to inhibit cortisol synthesis (e.g. ketoconazole, metyrapone) but they are of limited efficacy. Mifepristone is a powerful glucocorticoid type II receptor antagonist and, since it does not interfere with normal cortisol homeostatis type I receptor transmission, may be especially useful for treating the cognitive effects of Cushing's syndrome. However, the medication faces considerable controversy due to its use as an abortifacient. In February 2012, the FDA approved mifepristone to control high blood sugar levels (hyperglycemia) in adult patients who are not candidates for surgery, or who did not respond to prior surgery, with the warning that mifepristone should never be used by pregnant women.

Removal of the adrenals in the absence of a known tumor is occasionally performed to eliminate the production of excess cortisol. In some occasions, this removes negative feedback from a previously occult pituitary adenoma, which starts growing rapidly and produces extreme levels of ACTH, leading to hyperpigmentation. This clinical situation is known as Nelson's syndrome.

Treatment modality depends on the cause. Tumors may be removed surgically, but pituitary stalk interruption may persist. Usually, replacement of those hormones that are reduced due to failed feedback control systems will be necessary.

Medications consist mostly of antiandrogens, drugs that block the effects of androgens like testosterone and dihydrotestosterone (DHT) in the body, and include:

- Spironolactone: An antimineralocorticoid with additional antiandrogenic activity at high dosages

- Cyproterone acetate: A dual antiandrogen and progestogen. In addition to single form, it is also available in some formulations of combined oral contraceptives at a low dosage (see below). It has a risk of liver damage.

- Flutamide: A pure antiandrogen. It has been found to possess equivalent or greater effectiveness than spironolactone, cyproterone acetate, and finasteride in the treatment of hirsutism. However, it has a high risk of liver damage and hence is no longer recommended as a first- or second-line treatment.

- Bicalutamide: A pure antiandrogen. It is effective similarly to flutamide but is much safer as well as better-tolerated.

- Birth control pills: Consist of an estrogen, usually ethinylestradiol, and a progestin. They are thought to work by 1) stimulating production of sex hormone-binding globulin in the liver, which decreases free concentrations of testosterone in the blood; and by 2) suppressing luteinizing hormone (LH) secretion from the pituitary gland, which decreases production of testosterone by the gonads. Hence, they are functional antiandrogens. In addition, certain birth control pills contain a progestin that also has antiandrogenic activity. Examples include birth control pills containing cyproterone acetate, chlormadinone acetate, drospirenone, and dienogest.

- Finasteride and dutasteride: 5α-Reductase inhibitors. They inhibit the production of the potent androgen DHT.

- GnRH analogues: Suppress androgen production by the gonads and reduce androgen concentrations to castrate levels.

- Metformin: Antihyperglycemic drug used for diabetes mellitus. However, it is also effective in treatment of hirsutism associated with insulin resistance (e.g. polycystic ovary syndrome)

- Eflornithine: Blocks putrescine that is necessary for the growth of hair follicles

In cases of hyperandrogenism specifically due to congenital adrenal hyperplasia, administration of glucocorticoids will return androgen levels to normal.

Patients with Leydig cell hypoplasia may be treated with hormone replacement therapy (i.e., with androgens), which will result in normal sexual development and the resolution of most symptoms. In the case of 46,XY (genetically "male") individuals who are phenotypically female and/or identify as the female gender, estrogens should be given instead. Surgical correction of the genitals in 46,XY males may be required, and, if necessary, an orchidopexy (relocation of the undescended testes to the scrotum) may be performed as well.

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.

Hormone replacement therapy with estrogen may be used to treat symptoms of hypoestrogenism in females with the condition. There are currently no known treatments for the infertility caused by the condition in either sex.
