An analysis of the obstetric outcome of 125 consecutive pregnancies conceived in vitro and resulting in 100 deliveries.

Overview

One hundred twenty-five consecutive pregnancies conceived in vitro resulted in 100 deliveries of 115 babies. There were 23 clinical abortions (18.4%) and two tubal pregnancies. During the same interval 30 preclinical pregnancies occurred, but these pregnancies did not progress. There were 26 multiple pregnancies (37.1%) before the twelfth week; these reduced spontaneously to 14 (22.2%) multiple births at delivery. Eight infants were delivered prematurely, and three of these died. Three babies had some congenital abnormality. Vaginal bleeding occurred during pregnancy in 59% of patients. Cesarean section was the method of delivery in 56% of patients. Other complications of pregnancy were similar to those of comparable populations.
