title: Prolonged production of ovarian progesterone in pseudopregnant hamsters bearing deciduomata.
abstract: Decidual tissue in pseudopregnant hamsters prolonged ovarian progesterone release by one full day. The terminal decline in circulating progesterone occurred abruptly overnight in experimental and control animals and was synchronous with termination of hyperemia. During the hours immediately preceding luteal regression the mean progesterone level was significantly higher in hamsters with decidual tissue.
