The accurate observations and measurable investigations to identify the sex is the intrinsic step in biological profile development of the sample. In such scenario, sacrum identifies unknown sex and associated sex related functional differences more precisely. In the past, studies have shown that the morphological features of the sacrum are influenced by the sex hormone secretion and its associated reproductive functions. There are several parameters that can be considered when the sacral dimorphism is considered. Along with the sacrum measurements, the subpubic angle of the individual can also be measured. Among all the parameters used, the breadth and curvature of the sacrum were reliable indicators of sex among these measures. Additionally, it was also reported that none of the criteria could completely determine the sex of the bones. Therefore, it can be said that in order to determine the sex of the sacrum with 100 percent accuracy, consideration of all the parameters should be done. Further, other factors associated with the environment, physical stress, and genetic factors also affects this measurement. Hence, a groundwork about the previous research, is required while evaluating the sexual dimorphism in sacrum.
