What is the difference between a female femur from a male?

Answer 1

The neck of the femur forms a shallower angle with the long axis of the femur bone in a female. Forensic anthropologists have found differences in the measurements of the transverse width and length of the head of the femur between the sexes, and have posulated this application in identifying sex of dismembered murder victims; however, there are significant differences between races also.

The femur bone has many raised rough portions, and protubernces for the attachment of muscles, these are usually larger in males due to the greater pull of the attached muscles which are larger.

Answer 2

The female femur tends to be less robust and slightly more slender compared to the male femur. Additionally, the angle of the femoral neck is usually wider in females to accommodate differences in pelvic structure. These differences can be useful in forensic anthropology and determining the sex of skeletal remains.
