Abstract The concentration of progesterone in the plasma of the bandicoot was determined during pregnancy, during lactation, following removal of the young, and following surgical removal of the corpora lutea of lactation alone or along with the removal of the young. The corpus luteum of pregnancy continued into lactation and secreted progesterone for the first 19 days of lactation. In the later stages of lactation, the corpus luteum, which persisted morphologically until Day 45, was not secretory. Ovulation occurred approximately 20 days after the removal of the pouch young early in lactation. However after removal of both young and corpora lutea ovulation occurred in approximately 10 days. Thus early in lactation, when it is secreting progesterone, the corpus luteum may exert an additional ovulation inhibitory effect over and above that provided by suckling, but at later stages of lactation it is the suckling stimulus which is all important in inhibiting ovulation.
