A well-liked technique for inducing labour includes the midwife or physician inserting a small catheter by way of the lady’s cervix (the neck of the womb) and inflating a balloon on the opposite aspect, or generally on each side.
This mechanical stress can stimulate the manufacturing of prostaglandin (a pure hormone that helps put together for labour) and encourage a slight opening of the lady’s cervix. This enables the physician or midwife to interrupt the membranes (releasing the amniotic fluid) across the child with a particular plastic hook.
