ABSTRACT The urinary excretion of total androstenedione i. e. free, glucosiduronide and sulphate, testosterone and dehydroepiandrosterone during two normal menstrual cycle is presented. Epitestosterone was determinated during one cycle only. Both cycles were ovulatory as can be seen from the pregnanediol and oestriol determinations. The androstenedione and testosterone excretion values showed a caracteristic decrease from 12th to 16th day and an increase during the luteal phases, reaching their maximal levels between the 20th and 25th (cycle A) and 20th and 24th day (cycle B) respectively. The excretion values of epitestosterone were highest on 22nd and 23rd day. Dehydroepiandrosterone values were also slightly raised during the luteal phase of the cycle.

Routine Assay

A detailed procedure is presented for the assay of plasma progesterone. The routine assay is based on the use of antiserum which is covalently linked to microcrystalline cellulose, the double-antibody method being used as a reference separation system. This procedure gives high precision accompanied by small and acceptable losses of antiserum titre but without loss of sensitivity when compared with the double-antibody method. Ethanol is first added to the plasma (10vol. of plasma+1vol. of ethanol) after which a single extraction with light petroleum yields a constant recovery [92.4±1.2 (s.d.)% of added [3H]progesterone] and obviates the need for tracer recoveries on each sample being assayed. Distortions of the response curve owing to solvent residues have been almost eliminated. The assay can measure progesterone at all stages of the menstrual cycle when volumes of 200μl of plasma are used and this permits the detection of the periovulatory rise at its inception. Detailed specificity studies are presented for the assay end point itself and these are related to the responses to be expected in extracts of plasma. Progesterone-like activity was found in urine and a fourfold increase in excretion rates was observed between the follicular and luteal phase of the normal menstrual cycle.

Steroid Excretion

ABSTRACT Serial assays of urinary testosterone have been performed in seven normally menstruating women; in six of these pregnanediol estimations were also conducted and in four oestrogen determinations were made. All the cycles were of an ovulatory character as judged by the pattern of steroid excretion. In five subjects peaks of testosterone output were observed in the luteal phase of the cycle. In one a broad band of excretion extended from midcycle into the luteal phase, and in one the luteal peak was absent. Four women showed definite peaks of testosterone output at midcycle, and in two follicular phase peaks were also encountered. It is suggested that fluctuations in urinary testosterone excretion during the normal menstrual cycle result from the secretion of precursors of the hormone by the ovaries rather than by the adrenals.
