URINARY EXCRETION OF ANDROSTENEDIONE, TESTOSTERONE, EPITESTOSTERONE AND DEHYDROEPIANDROSTERONE DURING THE NORMAL MENSTRUAL CYCLE

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.
