In vitro incorporation of progesterone-1,2-3H in Fallopian tube and uterus of rat during pregnancy and postpartum period.
In vitro incorporation of 3H-progesterone into rat Fallopian tube and uterus during pregnancy and postpartum period is studied. The uptake of progesterone in oviduct and uterus falls sharply during mid-pregnancy (day 8-12 postcoitum) followed by a significantly high uptake prior to parturition. At the time of parturition, the tubal incorporation of radioactivity declines but resumes a rising profile towards day 5 postpartum. Similar pattern of uptake is observed in the uterus.
