Influence de la contrainte obstétricale sur le dimorphisme sexuel pelvien : application d'une nouvelle méthode d'analyse

Abstract : Extant Human pelvic bone is the most differentiated element of human skeleton between men and women. These differences constitute pelvic sexual dimorphism. However, the origin of this dimorphism raises questions. The function of parturition, and thus the obstetrical constraint, is the only major biological phenomenon allowing to separate men from women. Thereby, we wonder whether women whose pelvis possess the morphological traits recognized as female, or gynecoid, give birth eutocically, compared to women where childbirth is dystocic. Using a new analytical method based on the use of landmarks, measured on pelviscanner, we compared the quantitative values of gynecoid morphological traits to compare the anatomical characteristics of eutocic and dystocic pelvis. Our results have enabled us to identify 5 gynecoid variables associated with eutocic delivery modalities and for which our hypothesis that obstetrical constraints is one of the explanations of pelvic sexual dimorphism, is confirmed.
