Sex Estimation of the Pelvis - Medicine LibreTexts
The ability to determine sex from unknown skeletal remains is vital, and methods to do this on the various bones of the human skeleton have been researched extensively. Many researchers have emphasized the need for population specific data for methods which are based on measurements, as there are vast differences in body size in various populations. The pelvis is known to be the most sexually dimorphic part of the human body, and no discriminant function formulae for this bone are available for Greek or other Mediterranean groups. The purpose of this study was therefore to develop discriminant functions which can be used for sex determination on measurements of the pelvis of modern Greeks. A sample of 97 male and 95 female pelves in a skeletal collection housed in Heraklion, Crete, was used. Measurements were taken from the articulated pelvis, single os coxae and the sacrum.
The pelvis is the most accurate indicator of sex in the human skeleton. Its central role in the birth process means that the pelvis has several shape differences between females and males. Learning these features is one of the fundamental bases of forensic identification. The lower part of the pelvis, called the true pelvis , contains the birth canal in females. The top of the true pelvis is defined by the pelvic inlet.
The pelvis is an ideal anatomical structure to use in sex estimations of adult supcimens, because of the obvious functional relationship between the pelvic shape and reproduction in the female. Many studies have been done to determine pelvic characteristics useful in sex estimations. The most easily identified indicators will be mentioned in this text. The first two are generally the most useful, espeically for the budding osteologist. Clearly, the more experience an osteologist has in making sex estimations and the greater number and range of pelves examined, the better the estimations will be.
