Labor Induction With Dinoprostone in Oppose to Cervical Ripening Balloon as a Factor of BMI.

A Comparison Between Labor Induction With Dinoprostone and a Cervical Ripening Balloon in Women With a BMI>30 as Oppose With a BMI<30.

Women with a BMI>30 and women with a BMI<30 will be divided in a randomized controlled manor to 4 groups depending on the mode of labor induction and BMI value:

1. Dinoprostone in women with a BMI>30.
2. Dinoprostone in women with a BMI<30.
3. Cervical ripening balloon in women with a BMI>30.
4. Cervical ripening balloon in women with a BMI<30. The subjects will be followed until labor, and information regarding the success of induction, mode of delivery and time of delivery will be collected from patients' electronic files.

The study is a randomized controlled test in which women with a BMI>30 and women with a BMI<30 will sign an informed consent and then divided to 4 groups depending on the mode of labor induction and BMI value:

1. Dinoprostone in women with a BMI>30.
2. Dinoprostone in women with a BMI<30.
3. Cervical ripening balloon in women with a BMI>30.
4. Cervical ripening balloon in women with a BMI<30. All subjects participating in the study will be induced for obstetrical indications alone.

The subjects will be followed until labor, and information regarding the success of induction, mode of delivery and time of delivery will be collected from patients' electronic files.

The participants will finish participation in the study after delivery.

Inclusion Criteria:

• Any pregnant woman at term with an obstetric indication for labor induction.

Exclusion Criteria:

• Previous cesarean section.
• Positive Oxytocin challenge test.
• Positive contraction stress test.
