**1. Introduction**

Labor induction is the stimulation of uterine contraction artificially after the fetus has reached viability (after the 28th week of gestation) and before the spontaneous onset of labor for accomplishing vaginal delivery [1]. It is a common obstetric procedure primarily employed in the presence of obstetrics and medical conditions that threaten pregnancy continuation [2, 3]. Induction of labor has its indications that could be can be elective (planned) or emergency. Elective induction is usually done with prior planning by the health- provider and the mother when continuing the pregnancy beyond certain weeks has risk for the mother or the fetus, like in the case of PROM, DM, moderate hypertension postdate pregnancy, small or large for date baby. Emergency induction is done when there is an emergency maternal and fetal condition that necessities induction of labor immediately such as prolonged PROM, severe IUGR, intrauterine infection, pregnancy beyond 42 week, and preeclampsia and eclampsia [4].

Unfortunately, despite its undisputed importance for ending risky pregnancy, compared with the spontaneous onset of labor, induction has a potential risk of increased rate of cesarean birth and its complication along with different maternal and neonatal complications [5, 6]. Due to this, the World Health Organization (WHO) recommends induction to be performed only with a clear medical indication when expected benefits outweigh potential harms [2].

Although oxytocin is an effective means of labor induction, in women with a favorable cervix, as noted earlier, it is less effective as a cervical ripening agent. Many RCTs that have compared oxytocin with various prostaglandin (PG) formulations and other methods of cervical ripening confirm this observation.
