Abstract This study aimed to identify factors related to the successful induction of labor (IOL) among pregnancies complicated with fetal growth restriction (FGR). We performed a retrospective cohort study between January and December 2024 at Orléans University Hospital, Orléans, France. The study enrolled all singleton pregnancies complicated by FGR and underwent IOL. Logistic regression was used to reveal the associated factors relating to the success of IOL, following two criteria, including Bishop score after IOL greater than 7 points (criterion 1) and vaginal birth (criterion 2). Bishop score had a negative correlation with IOL duration. This study did not find statistically significant clinical factors related to the success of the Bishop score change of more than 7 points. However, absence of Doppler abnormalities and IOL at term, more than 37 weeks, were related to the success rate of vaginal delivery (OR 95% CI: 22.5 3.240–156.269 and OR 95% CI: 22.5 3.240–156.269, respectively; p < 0.05). Bishop score before IOL helps in reducing the duration of IOL. In FGR pregnancies with a normal Doppler ultrasound scan and gestational age at IOL greater than 37 weeks, these are good prognostic factors for vaginal delivery; however, further research is needed to explore more associated factors.
