The distribution of blood flow to the reproductive organs of rats near term

in Reproduction


The rate of ovarian and utero-placental blood flow through vessels of less than 25 μm diameter was examined with radioactive microspheres in 5 non-pregnant rats and 19 rats at Day 22 of pregnancy. Total blood flow to the reproductive organs was 0·559 ml/min in the non-pregnant animals and 13·2 ml/min in those near term, a 23-fold difference. The mean ovarian blood flow was high and increased from 0·202 ml/min to 0·845 ml/min. Myometrial and endometrial blood flow increased from 0·156 to 2·24 ml/min. The mean maternal placental blood flow at Day 22 of pregnancy was 0·76 ml/min or 121 ml.min-1.100 g-1. Litter size was negatively correlated with mean fetal weight but showed little relationship to mean placental weight or to mean maternal placental blood flow.
