The safety of cesarean section has improved dramatically over the past 50 years. During the past 20 years a greater awareness of and discussion about the symptomatic morbidity that can result for women following vaginal delivery has occurred and women's expectations for the outcome of pregnancy for them and their babies has increased. A culture of choice has been promoted in recent years, but contrary to the anticipated demand for less obstetric intervention by those promoting choice, there has been an increase in demand for delivery by cesarean section rather than the reverse. With the balance in favor of benefit for the baby from delivery by cesarean section, it is now difficult to sustain the argument favoring vaginal delivery rather than planned cesarean section, using maternal morbidity and mortality statistics. A critical evaluation of the costs indicates that there are probably few grounds for denying women their request for cesarean section for economic reasons. It seems likely, therefore, that in the near future those advising women on the options for delivery will need to ensure that the risks of vaginal delivery are explained as well as those for planned cesarean section.
