PLASMA PROGESTERONE CONCENTRATIONS AS AN INDEX OF OVULATION AND CORPUS LUTEUM FUNCTION IN NORMAL AND GONADOTROPHIN‐STIMULATED MENSTRUAL CYCLES

Abstract

Summary The occurrence of ovulation cab be deduced and corpus luteum function assessed in spontaneous and gonadotrophin‐induced menstrual cycles by appropriately timed plasma progesterone estimations. A screening procedure is suggested for the selection of suspect menstrual cycles requiring more detailed study of the luteal phase.
