Obstetric and neonatal outcomes of spontaneous labor with a large fetus depending on the gestational age

Study findings suggest that pregnant women whose estimated fetal weight is determined by ultrasound to be at least the 90th percentile at 36–37 weeks are at high risk for cesarean section and the birth of a large fetus. The optimal timing for delivery in these cases appears to be between the end of the 37th week and the beginning of the 39th week, when the lowest cesarean section rate was observed. Given these insights, further research into the effectiveness of labor induction for women with a large-for-gestational-age fetus, starting at 38 weeks of gestation, is warranted to potentially reduce the incidence of cesarean sections and complications associated with fetal macrosomia.
