Studies show that over 95% of those who TOLAC will labor without scar problems, and will VBAC safely and successfully despite having factors that diminish their odds, including those with:

  • more than one prior cesarean

  • prior cesarean for labor dystocia

  •  macrosomic baby (weighing 4000g or more)

  • advance maternal age

  • high body mass index (BMI)

  • longer pregnancy duration

  • single-layer uterine closure at the prior cesarean

  • thin scar

  • prior preterm cesarean

  • short interpregnancy/interdelivery interval


Rates of scar rupture depend heavily on labor management. Studies point towards scar ruptures often being caused by:

  • induction with an unripe cervix

  • induction using prostaglandin E2 (PGE2)

  • induction with misoprostol (now contraindicated)

  • high oxytocin dose

  • duration at high oxytocin dose

  • any other artificial augmentation of labor

  • Studies show that in the absence of labor-altering drugs, a uterine scar that has remained intact during pregnancy is very likely to remain intact through the birth

Did you know?

Studies and statistics show that scar rupture and VBAC success rates depend far more on the care provider than on the person or the scar

Uterine rupture rate is shown to be between 0.0%-3.8%, depending on the study cited, with the majority of studies showing rupture rates of 0.06%-0.7%, even with:

  • multiple cesareans

  • all forms of previous incisions

  • artificial induction

  • artificial augmentation of labor


VBAC decreases maternal mortality by 9 per 100,000 births over ERCD

With full informed consent, a healthy, responsible person can be given the choice to VBAC at home
