Interrelationships of circulating maternal steroid concentrations in third trimester pregnancies. III. Effect of intravenous cortisol infusion on maternal concentrations of estriol, 16 alpha-hydroxyprogesterone, 17 alpha-hydroxyprogesterone, progesterone, 20 alpha-dihydroprogesterone, delta 5-pregnenolone, delta5-pregnenolone sulfate, dehydroepiandrosterone sulfate, and cortisol. 1979

The effect of a large dose (1000 mg) of iv cortisol-hemisuccinate on circulating steroid concentrations in five women, 28--34 weeks, gestational age, is reported. Maternal concentrations of estriol, 16 alpha-hydroxyprogesterone, 17 alpha-hydroxyprogesterone, progesterone, 20 alpha-dihydroprogesterone, delta 5-pregnenolone, delta 5-pregnenolone sulfate, dehydroepiandrosterone sulfate, and cortisol were measured by RIA before and at 8 and 12 h after iv cortisol infusions at 0 and 8 h. Data were evaluated by repeated measure analysis of variance. Estriol and 17 alpha-hydroxyprogesterone suppressed initially (P less than 0.05) and suppressed further with retreatment and increased treatment time (P less than 0.05). Dehydroepiandrosterone sulfate and progesterone suppressed initially (P less than 0.05) but did not suppress further with retreatment and increased treatment time (P greater than 0.05). delta 5-Pregnenolone and delta5-pregnenolone sulfate increased initially (P less than 0.05) but did not increase further (P greater than 0.05). Concentrations of 16 alpha-hydroxyprogesterone and 20 alpha-dihydroprogesterone were unchanged by cortisol infusion initially (P greater than 0.1) and with retreatment and increased treatment time (P greater than 0.1).

D011284 Pregnenolone A 21-carbon steroid, derived from CHOLESTEROL and found in steroid hormone-producing tissues. Pregnenolone is the precursor to GONADAL STEROID HORMONES and the adrenal CORTICOSTEROIDS. 5-Pregnen-3-beta-ol-20-one,5 Pregnen 3 beta ol 20 one
D011374 Progesterone The major progestational steroid that is secreted primarily by the CORPUS LUTEUM and the PLACENTA. Progesterone acts on the UTERUS, the MAMMARY GLANDS and the BRAIN. It is required in EMBRYO IMPLANTATION; PREGNANCY maintenance, and the development of mammary tissue for MILK production. Progesterone, converted from PREGNENOLONE, also serves as an intermediate in the biosynthesis of GONADAL STEROID HORMONES and adrenal CORTICOSTEROIDS.

D003687 Dehydroepiandrosterone A major C19 steroid produced by the ADRENAL CORTEX. It is also produced in small quantities in the TESTIS and the OVARY. Dehydroepiandrosterone (DHEA) can be converted to TESTOSTERONE; ANDROSTENEDIONE; ESTRADIOL; and ESTRONE. Most of DHEA is sulfated (DEHYDROEPIANDROSTERONE SULFATE) before secretion.

D004092 20-alpha-Dihydroprogesterone A biologically active 20-alpha-reduced metabolite of PROGESTERONE. It is converted from progesterone to 20-alpha-hydroxypregn-4-en-3-one by the 20-ALPHA-HYDROXYSTEROID DEHYDROGENASE in the CORPUS LUTEUM and the PLACENTA.

D004964 Estriol A hydroxylated metabolite of ESTRADIOL or ESTRONE that has a hydroxyl group at C3, 16-alpha, and 17-beta position. Estriol is a major urinary estrogen. During PREGNANCY, a large amount of estriol is produced by the PLACENTA. Isomers with inversion of the hydroxyl group or groups are called epiestriol.
