Labor curves for breech presentations have never been described.<h4>Objectives</h4>The aims of this study were to examine the pattern of labor progression in women with a breech presentation and to determine whether the type of breech or parity can influence the speed of cervical dilatation.<h4>Study design</h4>We analyzed the labor data from 349 women with a term, singleton, and breech fetus after spontaneous onset of labor in 2010-2018. Cesarean deliveries were excluded. The patterns of labor progression were described by examining the relationship between the elapsed times from the full dilatation and cervical dilatation stages.
