Is fetal growth impaired after in vitro fertilization

Background. The objective was to study fetal growth parameters in in vitro fertilization (IVF) pregnancies and to investigate the relationship between fetal growth and maternal blood pressure. Methods. We examined 64 women, pregnant after in vitro fertilization, with repeated ultrasound examinations measuring biparietal diameter, femur length, and abdominal diameter 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. Femur length differed significantly on all three occasions, at 24 (−6.3%; 95%CI −7.7 to −5.1), 30 (−6.6%; 95%CI −8.0 to −5.3), and 36 (−3.9%; 95%CI; −5.0 to −2.8) weeks. Abdominal diameter demonstrated a significant deviation at 24 weeks (−1.6%; 95%CI −2.8 t...
