Abstract
The concentration of progesterone in maternal plasma of the bandicoot increased from 3.9-12.6 ng/ml between 11-4 days before parturition and remained at this level for at least 7 days. Concentrations of 13,14-dihydro-15-keto-prostaglandin[PG]F-2.alpha. 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. Apparently, PGF-2.alpha., but not progesterone, influences the initiation of parturition in this species.
