Summary. Women throughout the ages preferred to be delivered with their trunks vertical and most delivery positions illustrated in historical texts indicate that an upright posture with abducted thighs has been the rule. There is evidence that such a position considerably increases the outlet measurement of the pelvis. Primitive delivery positions often accentuate the mechanical forces usually acting on the pelvis.
