Background: One of problem in forensic pathology is identification of skeletonized remainders. The first step in determination of sex as it immediately excludes approximately half of population. To this regard pelvic is one of the best bones. This study aims to distinguish between man and women by use of anteroposterior pelvic x-ray and measurement of subpubic angles.

Methods: Subpubic angle was measured in the anteroposterior pelvic radiographs of 200 Iranian adults (100 men and 100 women). Data were analyzed through SPSS v. 22.

Results: The overall mean (SD) of subpubic angle was 118.49±22.09. The mean (SD) sub pubic angle in men was 101.51±13.40 and in women 135.47±13.40. In this study there was significant relation between means of subpubic angle in men and women، which is significant wider and larger in women (p<0.001).In this study demarking point was 115.92 degrees with accuracy of 91.5%, sensitivity 91% and specificity 92%.

Conclusion: Mean of subpubic angle is different from other population but there is a significant difference in the subpubic angle between men and women, and due to its high accuracy، and subpubic angle it could be used in gender identification of skeletal remainders.
