Abstract: Background: The morphological differences that are present on a hip bone can be attributed to the different reproductive functions of the two sexes and are influenced by sex hormones. The anatomy of the hip bone is morphologically different in males and females, making it of great interest in anthropology. Though nonmetric methods, such as visual examination of bone morphology for sex determination are entirely dependent on experience and expertise, anthropometry plays a crucial role in creating a quantifiable method that can be applied for sex determination from hip bones, allowing for a more objective and widespread application. This study examines sexual dimorphism in hip bones based on pubic parameters and their indices. Results: For this study, human hip bones were obtained from the Department of Anatomy, PGIMS Rohtak. A total of 86 paired hip bones of known sex, as recorded in official documentation, were analyzed, which included 58 male and 28 female specimens. Metrical parameters such as pubic length, length of the pubic crest, mid ? pubic width, and the length of the pubic bone up to the acetabulum were measured and compared between sexes. Results indicate that all measured pubic parameters were significantly larger in female hip bones compared to male hip bones, with the exception of mid - pubic width, which exhibited minimal variation between the sexes. Conclusion: Sexual dimorphism and the bilateral asymmetry of hip bones are appreciated in this study.
