“…Though our study findings cannot be generalized for our population due to the smaller sample size, this widely accepted simple rule of 90° SPA for sex determination may not still be applicable in our population as mean SPA in the male in our study is way more than the cut-off value. 4,5,6,7,8,9 SPA in our study is comparable to the SPA in the study done by Akhlaghi et al (140.0° ± 14.3° in male and 101.0° ± 13.3° in female), but wider than the SPA in above mentioned other similar studies. 8 The differences may be due to the different ethnic groups studied.…”

Introduction: Subpubic angle, an important parameter used for sex determination in the pelvis, is the angle between two inferior pubic rami below the symphysis pubis. This study was carried out to determine the subpubic angle among the individuals referred for pelvic and KUB radiographs in the department of Radiology and Imaging, Tribhuvan University, Teaching Hospital.Methods: Prospective cross-sectional study was done on 120 individuals. The subpubic angle was measured by drawing two tangent lines on the inferior border of the pubic rami. The subpubic angle of both sexes was measured. An independent sample t-test for equality of means was used to determine the difference between the two sexes regarding the subpubic angle. The correlation between the subpubic angle and the age of subjects was obtained using Pearson Correlation Coefficients in males and females.Results: The range of the subpubic angle in male was 82o to 122° and the mean was 104.72°±10.47°. In females, the range was 96o to 159° and the mean was 137.15°±11.92° with a significant statistical difference from the angle in male (p<0.05). The subpubic angle was not significantly correlated with age in males (r=0.029, p=0.824) whereas, in females, the correlation of subpubic angle with age was significant (r=-0.303, p=0.019).Conclusion: The mean subpubic angle was significantly wider in females than in males in this study. We found a weak negative correlation between subpubic angle and age in females whereas in the male there was no correlation between age and subpubic angle.

Suitability of foramen magnum measurements in sex determination and their clinical significance

et al. 2018

As a result of our study, the metric data we obtained will be useful in cases where the skeletons' sex could not be determined by any other methods. We believe that, our study may be useful for other studies in determining of sex from foramen magnum. Our measurements could give some information of the normal ranges of the foramen magnum in normal population, so that this can contribute to the diagnosis process of some diseases by imaging. (Folia Morphol 2018; 77, 1: 99-104).

“…The diagnosis of sex is not challenging for the examiner if a complete skeleton is available. Both the pelvis [4,5] and the cranium [6][7][8] provide highly accurate information. On the other hand, the analysis of sexual dimorphism in an incomplete or fractured skeleton can be a difficult task even for an expert.…”

Discriminant analysis of mandibular measurements for the estimation of sex in a modern Brazilian sample

et al. 2017

The present study aimed to evaluate the accuracy of mandibular measurements for sex determination in a Brazilian population. The sample was composed of 100 mandibles, of which 53 were female and 47 were male, and the average age was 57.03 years. The mandible measurement protocol was composed of 15 measurements, of which six were bilateral and nine were unique. Mandibles were directly measured using a digital caliper and a protractor. The descriptive analysis of the present study revealed higher mean values for male mandibles compared to those for female mandibles with the exception of the left mandibular angle. Among the 21 measures analyzed in this group, 15 were statistically significant (p < 0.05). Univariate discriminant analyses produced a mean percentage of correct predictions that varied between 49 and 79%. The association of variables increased the percentage of correct prediction of sex to vary from 76 to 86%. The receiver operator characteristic (ROC) curve analysis indicated that the best variable for estimating sex was bigonial breadth (BGB; area under the ROC curve (AUC) = 0.764) followed by the right maximum ramus height (MRHr; AUC = 0.763). A reference table for estimating sex in a Brazilian population using mandible measurements was developed based on the ROC curve analysis. Mandibular measures provide a simple and reliable method for sex discrimination in Brazilian adults due to the sexual dimorphism revealed by analysis of the metric variables and the satisfactory results demonstrated by discriminant formulas, ROC curve analysis, and the reference table.
