Pregnancy – Chapter 4 ANSWERS FOR YOUR BOOK ARE IN BOLD! There are four basic types of pelves. Each type of pelvis has implications for labor and birth. Describe the types of pelves below: Gynecoid: classic female pelvis, with rounded anterior and posterior segments. This type is most favorable for vaginal birth – Imagine a round baby’s head that can fit through pretty easily. Android: wedge-shaped inlet with a narrow anterior segment; it is typical of the male anatomy – It’s more triangular in shape. Anthropoid: anteroposterior diameter that equals or exceeds its transverse diameter. The shape is a long, narrow oval. Women with this type of pelvis can usually deliver vaginally, but their infant is more likely to be born in the occiput posterior (back of the fetal head toward the mother’s sacrum) position. – Babies are more likely to be born with their face up towards the ceiling. Moms will have a lot of back labor and it is very painful. Platypelloid: shortened anteroposterior diameter and a flat, transverse oval shape. This type is unfavorable for vaginal birth. – Flat and long, so duck lips like. A baby’s head will not fit through here. American College of Obsetricians and Gynecology (ACOG)
