The bulk of these definitions are from two primary sources, 
MedLinePlus
Health Information and CancerWeb's online dictionary.

17-alpha-hydroxyprogesterone (17-ohp) - a 21-carbon steroid produced by adrenals, ovaries, testes and placenta. 17 OHP is the metabolite of progesterone and 17-hydroxyprognenolone, and is a precursor to cortisol. (source)
21-hydroxylase - an intermediary hormone produced as a part of the bodies production of aldosterone and cortisol. Deficiency denotes Congenital Adrenal Hyperplasia. (chart)
adrenal - adj 1: of or pertaining to the adrenal glands or their secretions 2: near the kidneys n : either of a pair of complex endocrine glands situated near the kidney. (source)
adrenal crisis - an abrupt, life-threatening state caused by insufficient cortisol, a hormone produced and released by the adrenal gland. (source)
adrenal glands - triangular shaped glands located on top of the kidneys. They produce hormones such as estrogen, progesterone, steroids, cortisol, and cortisone, and chemicals such as adrenalin (epinephrine), norepinephrine, and dopamine. When the glands produce more or less hormones than required by the body, disease conditions may occur.  (source)
aldosterone - a steroid hormone produced by the adrenal cortex, that controls salt and water balance in the kidney. Abnormally high levels of this hormone cause sodium retention, high blood pressure, heart rhythm irregularities and possibly paralysis . (source)
ambiguous genitalia - a congenital physical abnormality where the outer genitals do not have the typical appearance of either sex. (source)
androgens - a class of sex hormones associated with the development and maintenance of the secondary male sex characteristics, sperm induction, and sexual differentiation. In addition to increasing virility and libido, they also increase nitrogen and water retention and stimulate skeletal growth. (source)
clitoroplasty - Any plastic surgery procedure on the clitoris.  (source)
congenital - existing at and usually before, birth, referring to conditions that are present at birth, regardless of their causation. (source)
cortef - a steroid drug. It is similar to cortisone, which is made in the adrenal glands. The drug has anti-inflammatory effects in the body which is the desired action. (source)
cortisol - the major adrenal glucocorticoid, stimulates conversion of proteins to carbohydrates, raises blood sugar levels and promotes glycogen storage in the liver.  (source)
cystourethrogram - a special X-ray study which allow visualisation of the bladder and urethra on X-ray. A catheter is placed into the urethra, through which a radio-opaque contrast material is injected. Subsequent X-rays will show the anatomy of the bladder and urethra. (source)
dexamethasone - steroid analogue (glucocorticoid), used as an anti-inflammatory drug.  (source)
endocrinology - the scientific study of the function and pathology of the endocrineglands (for example the thyroid gland, pituitary gland, etc.) (source)
endocrinologist - a medically qualified specialist in internal medicine who has subspecialised in the diseases of glandular organs for example diabetes mellitus. (source)
florinef - a medication that is used to decrease potassium in the blood. Also called fludrocortisol and fludrocortisone acetate(source)
fludrocortisone acetate - see florinef
glucocorticoid - corticosteroid substances (drugs or hormones) that are involved in carbohydrate metabolism by promoting gluconeogenesis and the formation of glycogen at the expense of lipid and protein synthesis. They are steroid based and possess anti-inflammatory and immunosuppressive properties. Glucocorticoids are also produced normally by the adrenal cortex and provide for the response to stress.  (source)
hermaphrodite - (Not applicable to Congenital Adrenal Hyperplasia) An organism which has both male and female organs, and produces both male gametes (sperm) and female gametes (eggs). The organism can have both types of organs at the same time (simultaneous hermaphrodite) or have one type early in life and the other type later in life (sequential hermaphrodite).  (source)
hydrocortisone - the main glucocorticoid secreted by the adrenal cortex. Its synthetic counterpart is used, either as an injection or topically, in the treatment of inflammation, allergy, collagen diseases, asthma, adrenocortical deficiency, shock, and some neoplastic conditions. (source)
hyperplasia - the abnormal multiplication or increase in the number of normal cells in normal arrangement in a tissue.  (source)
hydroxylase - a type of enzyme which adds -OH groups to its substrate during hydroxylation reactions by attaching oxygen atoms to it.  (source)
hyperkalemia - A condition caused by higher than normal level of potassium in the bloodstream. (source)
hyponatremia - a disorder of fluid and electrolyte balance caused by excessive release of antidiuretic hormone (ADH).  Also known as Dilutional hyponatremia and Syndrome of Inappropriate Secretion of Antidiuretic Hormone (SIADH). (source1, source2
intersex - (Not applicable to Congenital Adrenal Hyperplasia) Relating to or characterized by the condition of having both male and female characteristics; being intermediate between the sexes.  (source)
karyotype - the complete set of chromosomes of a cell or organism. Used especially for the display prepared from photographs of mitotic chromosomes arranged in homologous pairs. (source)
late onset CAH - a non-classical CAH which occurs in approximately 1 out of 100 people, and as high as 1 in 27 in some ethnic populations. Presents later into infancy, or can even be acquired in adulthood. (source)
metabolite - Any substance produced or used during metabolism (digestion). In drug use, a metabolite usually refers to the end-product (what is remaining after metabolism). (source)
prednisolone - A glucocorticoid with the general properties of the corticosteroids. It is the drug of choice for all conditions in which routine systemic corticosteroid therapy is indicated, except adrenal deficiency states. Pharmacological action: steroidal anti-inflammatory agents, antineoplastic agent, hormonal, glucocorticoids, synthetic. Chemical name: Pregna-1,4-diene-3,20-dione, 11,17,21-trihydroxy-, (11beta)- (source)
prednisone - Synthetic corticosteroid with powerful anti-inflammatory and antiallergic activity. (source)
pregnenolone - a precursor hormone synthesized from cholesterol, principally in the adrenal glands, but also in the liver, skin, brain, testicles, ovaries, and retina of the eyes. Also called pregenolone (source)
progesterone - female sex hormone that induces secretory changes in the lining of the uterus essential for successful implantation of a fertilized egg. (source)
proximal hypospadias - an abnormality of anterior urethral development in which the urethral opening is ectopically located on the ventrum of the penis proximal to the tip of the glans penis. The opening may be as proximal as the scrotum or perineum. The more proximal the urethral defect, the more likely the penis will have associated ventral shortening and curvature, called chordee. (source)
mineralocorticoids - A group of hormones (the most important being aldosterone) that regulate the balance of water and electrolytes (ions such as sodium and potassium) in the body. The mineralocorticoid hormones act on the kidney (and specifically on the tubules of the kidney). (source)
virilization - The process of developing masculine sex characteristics in a female. May include an increase in body hair, facial hair, deepening of the voice, male-pattern baldness, and clitoral enlargement. May result from excessive testosterone production in endocrine glands or use of anabolic steroids. (source)
