[Anatomical and physiological bases of labor onset]. / Bases anatomiques et physiologiques du déclenchement du travail.

The induction of labor involves a series of complex mechanisms, the control of which is only partially explained in humans. It is accepted today that the maturing of the uterine cervix is independent of the onset of uterine contractions. These two phenomena are regulated by a complex system where prostaglandins play a key role.
