METHODS: We examined 64 women, pregnant after in vitro fertilization, with repeated ultrasound examinations measuring biparietal diameter, femur length, abdominal diameter and fetal weight at 24, 30, and 36 weeks of gestation. We calculated deviations in percent from expected values in regards to biparietal diameter, femur length, abdominal diameter, and fetal weight. Blood pressure was measured every second week. RESULTS: Biparietal diameter in the study group was significantly smaller at 24 (-3.3%, 95%CI -4.4 to -2.2) and 30 (-1.4%; 95%CI -2.5% to -0.3) weeks.
