Identification of sex from remains of skeleton is an important demographic assessment in medico legal investigations and anatomists are frequently consulted by law enforcement authorities for it. Present study is conducted on 50 human humeri (all are dry, and undamaged. 25 are male and 25 are female) Five parameters are studied. The mean values of all parameters are significantly higher in males than in females (P<0.001) with univariate analysis. Not a single parameter gives us an idea of sex of humerus with 100% accuracy. The single best parameter is CA (Circumference of anatomical neck of humerus) with an accuracy of 64 % in males and 68 % in females.
