However, the role and the mechanisms responsible for the adrenal androgen excess in women with PCOS are not well understood.Our aim was to compare 17-hydroxyprogesterone (17-OHP), androstenedione, dehydroepiandrosterone sulfate (DHEAS) and cortisol responses to a low dose (1 microg) ACTH ...
A preponderance of basic luteinizing hormone (LH) isoforms accompanies inappropriate hypersecretion of both basal and pulsatile LH in adolescents with poly... Fasting serum concentrations of 17-hydroxyprogesterone (17-OHP), androstenedione, testosterone, estrone, estradiol, and sex hormone-binding globulin...
In pregnant women, blood progesterone continues to rise, losing its normal periodicity. In congenital 17α-hydroxylase deficiency, the ratio between progesterone and 17α-hydroxyprogesterone is abnormal, with progesterone increasing and 17α-hydroxyprogesterone decreasing. Chemical properties White powder ...
Antibody 144A was raised in rabbits against 17-hydroxyprogesterone-3-0-carboxymethyloxime-BSA. The labeled steroid used in the radioimmunoassay (RIA) was methyl-17α-hydroxyprogesterone acetate, 6α-[1,2-3 H(N)]- obtained from NEN (CAT NO: NET 480) while the reference preparation was medroxy...
The median serum values found were: 17-hydroxyprogesterone 614ng/ml, renin 500 μUI/ml, ACTH 197 pg/ml, cortisol 10,3 μg/dl, androstenediona 15.7 ng/ml, testosterone 431 ng/dl, DHEAS-SO4 58.5 µg/dl, Na+ 123.5 mmol/l (min. 103), K+ 8.2 mmol/l (max. 10.6). Both ...
Follicle stimulating hormone, luteinizing hormone, sex hormone binding globulin, 17α-hydroxyprogesterone, estradiol, androstenedione, total and free testosterone, dehydroepiandrosterone sulfate levels and hirsutism scores were determined in all patients before treatment and at every 6 months during the ...
(25OHD concentration between 75 and 150 nmol/L). Salivary concentrations of estradiol, progesterone, 17-hydroxyprogesterone and androgens, as well as urine concentrations of FSH and LH, were assayed during the first 18 months of life (once a month in the first 6 months, bimonthly between ...
Salivary concentrations of estradiol, progesterone, 17-hydroxyprogesterone and androgens, as well as urine concentrations of FSH and LH, were assayed during the first 18 months of life (once a month in the first 6 months, bimonthly between months 6 and 12, and then every three months). At ...
