ABSTRACT Two amenorrhoeic women were given a course of 10 injections of human menopausal gonadotrophin (HMG) in daily doses corresponding to 260 IU of follicle stimulating hormone (FSH) activity and 165 IU of interstitial cell stimulating hormone (ICSH) activity. In both patients an extensive ovarian stimulation was observed as indicated by the greatly increased urinary excretion of oestrone, 17β-oestradiol and oestriol. When HMG-treatment was followed subsequently by the administration of human chorionic gonadotrophin (HCG) for 5 days in a total dose of 18 000 and 30 000 IU, respectively, functional corpus luteum tissue was formed in both patients as evidenced by a huge rise in urinary pregnane-3α,20α-diol excretion and by the secretory transformation of a previously atrophic endometrium. At the approximate height of the follicular phase tracer doses of 3H-labelled dehydroepiandrosterone sulphate (DHAS) and 14C-labelled dehydroepiandrosterone (DHA) were administered to both patients in the form of a continuous intravenous infusion of 10 hours' duration. Infusion of the same dose was repeated under identical experimental conditions at the approximate height of the luteal phase. In both patients, very little radioactive material was associated with oestrone and 17β-oestradiol and none with oestriol isolated from 96-hours' urine specimens obtained at both phases of ovarian stimulation. It is concluded that — in contradistinction to the situation in pregnant women — circulating DHAS is not a significant precursor of urinary oestrogens in non-pregnant women.

ABSTRACT The following steroids, [7α-3H]5-androstene-3β,16α,17β-triol and [4-14C] 5-androstene-3β,16β,17β-triol were biosynthesized and their metabolism was studied in two subjects at midgestation, following placental perfusion in situ. Among the metabolites isolated in a radiochemically homogeneous form, exclusively 3H-labelled 16α,17β-dihydroxy-4-androsten-3-one was isolated from the extracts of placentas and perfusates. Exclusively 14C-labelled 16β,17β-dihydroxy-4-androsten-3-one was isolated from the placentas and perfusates and 16-epioestriol (1,3,5(10)-oestratriene-3,16β,17β-triol) from the placentas, perfusates and urine specimens. The following compounds contained both 3H and 14C-label: oestriol (placentas and urine specimens) and 5β-androstane-3α,16α,17β-triol (urine specimens). The 3H/14C-ratio of oestriol isolated from the urine specimens was much lower than that of urinary 5β-androstane-3α,16α,17β-triol, or that of the oestriol isolated from the placentas. The 3H/14C-ratio of the oestriol isolated from the urine 2–4 days following the perfusion was lower than that of the perfused material. It is concluded that a considerable amount of the 16-epioestriol secreted by the placenta is gradually converted to oestriol by the maternal organism. A limited conversion occurs also in the placenta.
