. Local uterine blood flow was measured by the hydrogen gas clearance method in 36 women before and after injection of oxytocin. In women with secondary amenorrhoea mean myometrial blood flow was 99.0 ± 12.75 ml/min.100 g. No or only a slight reduction of myometrial blood flow was obtained after administration of oxytocin. During the first few days after therapeutic abortion performed in the first trimester of pregnancy, mean myometrial blood flow was 124.3 ± 15.71 ml/min. 100 g. After injection of oxytocin, myometrial blood flow was reduced to a mean of 19.7 ± 6.07% of controls. In the first trimester of pregnancy and during the first few days after therapeutic abortion, cervical uterine blood flow was not or only slightly reduced after administration of oxytocin.
