The gynecoid pelvis is the typical female pelvis best suited for vaginal delivery. The android pelvis is triangular (or heart-shaped) and the shape can cause difficulty during fetal descent. The anthropoid pelvis is more likely to result in a posterior fetal presentation due to its oval shape at the inlet that is in the anterior-posterior plane. The platypelloid pelvis usually prevents vaginal delivery owing to the fetus descending in a transverse presentation.
