40% of moms who are induced wind up with a C-section. This is for two main reasons.
Reason 1-stalled labor. If your body isn't ready to go into labor, it's not going to dilate no matter what they do to it. They break your water in the process, so there's no going back, and you wind up with a C-section to avoid infection, or even if they didn't break your water, if it's a true emergency and baby really does need to be born, then they section you if you're not dilating fast enough.
Reason 2-fetal distress. Induced labors are NOT the same as natural labors. Your brain is not getting the usual dose of the oxytocin cocktail and so your endorphins run lower than in a natural labor. This, combined with the harder, faster contractions of Pitocin makes it really hard on baby, and they often do not tolerate labor well, and go into distress (or suspected distress... that's a whole different issue).
