The indication for labor induction has been increasing in the world. It is known that cervical conditions are directly associated to the success of labor induction. Knowledge of cervix anatomy and physiology during pregnancy and of the different methods for cervical ripening is essential for indicating the best cervical ripening method in a given situation, therefore obtaining the best outcomes following labor induction. This is a challenge for obstetricians where not every method is readily available and accessible and C-sections rates are very high as in Brazil. Some methods are discussed in this paper including breast stimulation, membrane stripping, and the use of relaxin, oxytocin, prostaglandins, hyaluronidase, mifepristone, laminaria and Foley catheter.
