What characteristic defines an android pelvic shape in pregnant clients?

An android pelvic shape, often described as wedge-shaped and narrow, is typically considered nonfavorable for vaginal birth. This pelvic type resembles the male pelvis more closely and is characterized by its narrow dimensions, which can make the birth canal constricted. The implications of this narrow pelvic structure can lead to difficulties during the labor process, increasing the likelihood of needing interventions such as cesarean sections. It contrasts with favorable pelvic shapes, which tend to be broader and allow for more room for the fetus to descend during delivery. Understanding the characteristics of the android type is crucial for predicting labor outcomes in obstetric care.
