The word pituitary refers to the pituitary gland, which regulates the production of certain chemicals called hormones.

The pituitary gland, also called the hypophysis, is a gland at the base of the brain that produces many different hormones.

The hypothalamus releases hormones that regulate the production of other hormones.

Thus, dwarfism can result if there is a deficiency in any of these hormones, if there is a failure in the receptor cells receiving the hormonal stimuli, or if the target cells are unable to respond.

When none of the hormones of the anterior pituitary are adequately produced, this is called panhypopituitarism.

A pediatric endocrinologist, a doctor specializing in the hormones of children, administers this type of therapy before a child's bone growth plates have fused or joined.

If growth hormone is not the only hormone deficiency, the doctor must prescribe ways to raise the levels of the other deficient hormones, if these options are available.

A careful balancing of all of the hormones produced by the pituitary gland is necessary for patients with panhypopituitarism, making this form of dwarfism complex and difficult to manage.

A panhypopituitarism dwarf does not pass through the initial onset of adult sexual development (puberty) and never produces enough gonadotropic (sex) hormones to develop adult sexual function.

Adrenocorticotropic hormone (ACTH)-Also called adrenocorticotropin or corticotropin, this hormone is produced by the pituitary gland to stimulate the adrenal cortex to release various corticosteroid hormones.

Male hormones are produced in small quantities by all women, but in women with PCOS, levels of male hormone (androgens) are slightly higher than in other women.

Other women, including those with PCOS, are treated with hormones.

Prescribed hormones depend on which particular hormones are deficient or out of balance.

Many women, including those with PCOS, are successfully treated with hormones for oligomenorrhea.

For women who do not respond to hormones or who continue to have an underlying condition that causes oligomenorrhea, the outlook is less positive.

Ovary-One of the two almond-shaped glands in the female reproductive system responsible for producing eggs and the sex hormones estrogen and progesterone.

While the early onset of puberty may seem fairly benign, in fact it can cause problems when hormones trigger changes in the growth pattern, essentially halting growth before the child has reached normal adult height.

Precocious Puberty Causes and Symptoms Puberty begins when the brain secretes a hormone that triggers the pituitary gland to release gonadotropins, which in turn stimulate the ovaries or testes to produce sex hormones.

These sex hormones (especially estrogen in girls and testosterone in boys) are what causes the onset of sexual maturity.

The condition may result from a benign tumor in the part of the brain that releases hormones.

Blood tests can highlight higher-than-normal levels of hormones.

Certain body chemicals known as hormones rise and fall during the month, causing the menstrual cycle to occur.

In turn, the pituitary releases its own hormones called gonadotrophins that stimulate the gonads and adrenals.

It is interesting to note that the gonadotrophins are the same for males and females, but the sex hormones they induce are different.

Functioning tumors may cause overproduction of sex hormones.

By contrast, a normal pituitary overproduces if it senses there are not enough hormones in the circulation.

Children with these syndromes do not experience normal puberty, but it may be induced by giving them hormones at the proper time.

Notice that virilizing requires abnormal hormones in the female, while feminizing results from absent hormones in the male.

Male hormones transform it if they are present.

Maternal serum analyte screening-A medical procedure in which a pregnant woman's blood is drawn and analyzed for the levels of certain hormones and proteins.

The pituitary is a small gland located at the base of the brain, which releases certain hormones that are important to the functioning of other organs or body systems.

The pituitary hormones travel throughout the body and are involved in a large number of activities, including the regulation of growth and reproductive functions.

This input from the hypothalamus regulates the pituitary's release of hormones.

Input from the hypothalamus should also direct the pituitary to stop releasing hormones.

As the adenoma grows, it may disrupt other pituitary tissue, interfering with the release of other hormones.

These tumors can secrete hormones or cause changes in hormone production in nearby glands.

Gland-A collection of cells whose function is to release certain chemicals (hormones) that are important to the functioning of other, sometimes distantly located, organs or body systems.

This congenital defect means that the infant does not produce sufficient thyroid hormones, resulting in abnormal growth and development as well as slower mental function.

Endocrine system-A group of ductless glands and parts of glands that secrete hormones directly into the bloodstream or lymphatic system to control metabolic activity.

The decreased testosterone also causes an increase in two other hormones, follicle stimulating hormone (FSH) and luteinizing hormone (LH).

Oral contraceptives, or birth control pills, contain synthetic forms of two hormones produced naturally in the body.

These hormones, estrogen and progestin, regulate the female menstrual cycle.

Some types of oral contraceptives use only progestational hormones, but most use a combination of estrogen and progestin.

Masturbation becomes almost universal at puberty in response to normal surges in sex hormones and sexual drive.

Hormones secreted from the mother's ovaries and a chemical secreted by the trophoblasts begin to prepare the uterine wall.

Hyperthyroidism is the overproduction of thyroid hormones by an overactive thyroid.

In turn, the production of these hormones is controlled by thyroid-stimulating hormone (TSH) that is produced by the pituitary gland.

When production of the thyroid hormones increases despite the level of TSH being produced, hyperthyroidism occurs.

The excessive amount of thyroid hormones in the blood increases the body's metabolism, creating both mental and physical symptoms.

Radioimmunoassay (a test to show concentrations of thyroid hormones with the use of a radioisotope mixed with fluid samples) helps confirm the diagnosis.

Antithyroid drugs are often administered to help the patient's body cease overproduction of thyroid hormones.

Hypogonadism is the condition in which the production of sex hormones and germ cells (sperm and eggs) is inadequate.

Along with producing eggs and sperm, they produce sex hormones that generate all the differences between men and women.

The pituitary hormones are the same for males and females, but the gonadal hormones are different.

Hormones can be inadequate during or after each stage of development-embryonic and adolescent.

The organs affected principally by sex hormones are the male and female genitals, both internal and external, and the female breasts.

Again, not every defect is due to inadequate hormones.

For several reasons, the pituitary gland can fail to produce hormones.

Failure of the pituitary is called hypopituitarism and, of course, leaves the gonads with no stimulation to produce hormones.

The role of female hormones in female sexual activity is less clear, although hormones strengthen tissues and promote healthy secretions, facilitating sexual activity.

Congenital adrenal hyperplasia (CAH) is a genetic disorder characterized by a deficiency in the hormones cortisol and aldosterone and an over-production of the hormone androgen.

Congenital adrenal hyperplasia (CAH) is a form of adrenal insufficiency in which 21-hydroxylase, the enzyme that produces two important adrenal steroid hormones, cortisol and aldosterone, is deficient.

Because cortisol production is impeded, the adrenal gland over-produces androgens (male steroid hormones).

For some forms of CAH, prenatal diagnosis is possible through chronic villus sampling in the first trimester and by measuring certain hormones in the amniotic fluid during the second trimester.
