The concentration of progesterone in maternal plasma of the bandicoot increased from 3.9 to 12.6 ng/ml between 11 and 4 days before parturition and remained at this level for at least 7 days. Concentrations of 13,14-dihydro-15-keto-prostaglandin F-2α increased from basal levels of 288 pg/ml (4 days before birth) to maximal levels of 2534 pg/ml immediately after parturition, then decreased progressively. It is suggested that PGF-2α, but not progesterone, influences the initiation of parturition in this species.
