Metabolism of deoxycorticosterone and deoxycorticosterone sulfate in men and women. 1982

M L Casey, and P C MacDonald

In this investigation we found that little of intravenously infused [14C]deoxycorticosterone (DOC) was converted to [14C]DOC-SO4 that entered plasma. Moreover little of intravenously infused [3H]DOC-SO4 was metabolized by way of DOC except by intestinal bacterial enzymes. However evidence was obtained that plasma DOC is converted to DOC-SO4 in liver, but little of the DOC-SO4 formed in liver escapes into blood; rather the DOC-SO4 enters bile and in the intestine is converted, in part, to progesterone (or metabolites thereof) by the action of bacterial enzymes. The estimated intrahepatic fractional conversion of DOC to DOC-SO4 was significantly greater in premenopausal women (0.72 +/- 0.118, mean +/- SEM) than in men (0.28 +/- 0.036, P less than 0.005).

D008593	Menopause	The last menstrual period. Permanent cessation of menses (MENSTRUATION) is usually defined after 6 to 12 months of AMENORRHEA in a woman over 45 years of age. In the United States, menopause generally occurs in women between 48 and 55 years of age.	Change of Life, Female

D011276	Pregnanediol	An inactive metabolite of PROGESTERONE by reduction at C5, C3, and C20 position. Pregnanediol has two hydroxyl groups, at 3-alpha and 20-alpha. It is detectable in URINE after OVULATION and is found in great quantities in the pregnancy urine.

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.
