The aim of this study was to use the Ischiopubic index to explore the sex differences in the pelvis betweenthe male and female bones. The pelvis is characterized by sexually dimorphic features and thus it can beused for sex determination while establishing the biological profile in unknown skeletal remains. In thisstudy we have assessed the sex prediction potential of the Ischiopubic index using 72 dry innominate hipbones (38 male and 34 female) belonging to South Indian population. The lengths of the pubis and ischiumwere measured in these bones and the Ischiopubic index was calculated as per Washburn’s formula. TheIschiopubic index was calculated to be 85.46 ± 3.63 mm. in males (Range 74.15 - 95.28 mm.) and 97.75 ±4.10 mm. in females (Range 89.56 - 116.37 mm.). Application of the Student’s t test showed that there wasa statistically significant difference in the Ischiopubic index between the male and female pelvic bones witha p <0.001.
