Pelvimetry is the measurement of the female pelvis. [1] It can theoretically identify cephalo-pelvic disproportion, which is when the capacity of the pelvis is inadequate to allow the fetus to negotiate the birth canal. However, clinical evidence indicate that all pregnant women should be allowed a trial of labor regardless of pelvimetry results.
In obstetrics, position is the orientation of the fetus in the womb, identified by the location of the presenting part of the fetus relative to the pelvis of the mother. . Conventionally, it is the position assumed by the fetus before the process of birth, as the fetus assumes various positions and postures during the course of chil
The adoption of the non-lithotomy positions is also promoted by the natural childbirth movement. Being upright during labour and birth can increase the available space within the pelvis by 28–30% giving more room to the baby for rotation and descent.

Presentation of twins in Der Rosengarten ("The Rose Garden"), a German standard medical text for midwives published in 1513. In obstetrics, the presentation of a fetus about to be born specifies which anatomical part of the fetus is leading, that is, is closest to the pelvic inlet of the birth canal.
A male pelvis (left) compared to a female pelvis (right) from a posterolateral view. Differences in the sciatic notch and overall shape of the ilium can be observed. Examination of the pelvis is the most useful method for identifying biological sex through the skeleton.
Ardi (ARA-VP-6/500) is the designation of the fossilized skeletal remains of an Ardipithecus ramidus, thought to be an early human-like female anthropoid 4.4 million years old. It is the most complete early hominid specimen, with most of the skull, teeth, pelvis, hands and feet, [ 1 ] more complete than the previously known Australopithecus ...
