The gynecoid pelvic type is the typical, traditional female pelvis (present in 50 of women) that is best suited for childbirth. Fetal descent through a platypelloid pelvis is usually in a transverse presentation and will not allow for a vaginal birth. Fetal descent through an anthropoid pelvis is more likely to be in a posterior (facing the woman's front) rather than anterior (facing the woman's back) presentation. The android pelvis resembles a typical male pelvis, and this pelvic shape can also cause difficulty during fetal descent.
