A randomized controlled trial of extra‐amniotic ethinyloestradiol in ripening the cervix at term

Abstract
A double-blind radomized controlled trial investigated the use of extra-amniotic ethynylestradiol for ripening the unfavorable cervix at term. Twenty-five primigravidae were treated with 150 mg ethynylestradiol gel while 24 primigravidae were treated with gel alone. There was no statistical difference between the ethynylestradiol and control groups in either mean change in Bishop score or the induction-to-delivery interval.
