11 patients with polycystic ovary syndrome (hirsutism and oligomenorrhoea), but with no deficiency of 21-hydroxylase or 3 beta-hydroxysteroid dehydrogenase, had abnormal cortisol metabolism. The high ratio of 5 alpha to 5 beta cortisol metabolites in the urine is consistent with enhanced activity of 5 alpha-reductase. Urinary total cortisol metabolites were higher in patients than controls. Increased 5 alpha-reductase activity in liver and skin enhances hepatic cortisol metabolism at the expense of androgen excess and may be the underlying abnormality in polycystic ovary syndrome.

UI	MeSH Term	Description	Entries
D007273	Injections, Intramuscular	Forceful administration into a muscle of liquid medication, nutrient, or other fluid through a hollow needle piercing the muscle and any tissue covering it.	Intramuscular Injections,Injection, Intramuscular,Intramuscular Injection
D007986	Luteinizing Hormone	A major gonadotropin secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Luteinizing hormone regulates steroid production by the interstitial cells of the TESTIS and the OVARY. The preovulatory LUTEINIZING HORMONE surge in females induces OVULATION, and subsequent LUTEINIZATION of the follicle. LUTEINIZING HORMONE consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the three pituitary glycoprotein hormones (TSH, LH and FSH), but the beta subunit is unique and confers its biological specificity.

D008099	Liver	A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances.	Livers
D011085	Polycystic Ovary Syndrome	A complex disorder characterized by infertility, HIRSUTISM; OBESITY; and various menstrual disturbances such as OLIGOMENORRHEA; AMENORRHEA; ANOVULATION. Polycystic ovary syndrome is usually associated with bilateral enlarged ovaries studded with atretic follicles, not with cysts. The term, polycystic ovary, is misleading.

D003348	Cortisone	A naturally occurring glucocorticoid that has been used in replacement therapy for ADRENAL INSUFFICIENCY and as an anti-inflammatory agent. Cortisone itself is inactive; it is converted in the liver to the active metabolite HYDROCORTISONE. (From Martindale, The Extra Pharmacopoeia, 30th ed, p726)	17-Hydroxy-3,11,20-trioxopregn-4-en-21-yl acetate,Adreson,Cortisone Acetate,Cortone Acetate
D005043	Etiocholanolone	The 5-beta-reduced isomer of ANDROSTERONE. Etiocholanolone is a major metabolite of TESTOSTERONE and ANDROSTENEDIONE in many mammalian species including humans. It is excreted in the URINE.	3-alpha-Hydroxy-5-beta-Androstan-17-One,5-beta-Androsterone,3 alpha Hydroxy 5 beta Androstan 17 One,5 beta Androsterone

D006854	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.

D000324	Adrenocorticotropic Hormone	An anterior pituitary hormone that stimulates the ADRENAL CORTEX and its production of CORTICOSTEROIDS. ACTH is a 39-amino acid polypeptide of which the N-terminal 24-amino acid segment is identical in all species and contains the adrenocorticotrophic activity. Upon further tissue-specific processing, ACTH can yield ALPHA-MSH and corticotrophin-like intermediate lobe peptide (CLIP).
