[Urinary excretion of 11-deoxy-17-ketosteroids during the normal menstrual cycle (author's transl)]. 1975

P Bolufer, and A Rodríguez, and J M Micó

Urinary excretion of 11-deoxy-17-ketosteroids was studied in 20 to 22 women with normal menstrual cycles on the 7, 10, 14 and 20th days of their cycles. The fraction studied showed a significant cyclic variation with a type of pattern for Androsterone and Aetiocholanolone and another one for the Dehydroepiandrosterone. The possibity of one metabolic path for the former metabolites and a different one for the latter, plus its close conection with the functional changes of the ovary, were arrived at.

UI	MeSH Term	Description	Entries
D008598	Menstruation	The periodic shedding of the ENDOMETRIUM and associated menstrual bleeding in the MENSTRUAL CYCLE of humans and primates. Menstruation is due to the decline in circulating PROGESTERONE, and occurs at the late LUTEAL PHASE when LUTEOLYSIS of the CORPUS LUTEUM takes place.
D010053	Ovary	The reproductive organ (GONADS) in female animals. In vertebrates, the ovary contains two functional parts: the OVARIAN FOLLICLE for the production of female germ cells (OOGENESIS); and the endocrine cells (GRANULOSA CELLS; THECA CELLS; and LUTEAL CELLS) for the production of ESTROGENS and PROGESTERONE.	Ovaries
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.

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

D000738	Androsterone	A metabolite of TESTOSTERONE or ANDROSTENEDIONE with a 3-alpha-hydroxyl group and without the double bond. The 3-beta hydroxyl isomer is epiandrosterone.	3-alpha-Hydroxy-5-alpha-Androstan-17-One,5 alpha-Androstan-3 alpha-ol-17-one,Epiandrosterone,3 alpha Hydroxy 5 alpha Androstan 17 One,5 alpha Androstan 3 alpha ol 17 one
