The key difference between male and female femur is that the male femurs are less angled than the female femurs.
The femur is the longest, strongest and heaviest bone of our skeleton system. This is the thigh bone. Therefore, the main function of the femur is to transmit the weight of your body from hip bone to legs and also it provides anchor points to muscles. Femur has two joints from two sides, and they are hip joint and knee joint.
Furthermore, there are three distinct regions in the femur namely proximal femur, shaft femur and distal femur. In the proximal region, you can find the head and neck of the femur and greater and lesser trochanter. In the shaft region, there are a pectineal line, gluteal tuberosity, linea aspera, popliteal fossa and medial and lateral supracondylar ridges. Finally, in the distal region, there are medial and lateral condyles, medial and lateral epicondyles, trochlear groove and intercondylar fossa. When you look at the angles of the femur, there are two femoral angles; angle of inclination and torsion angle. Though the male and female skeleton show similar outer look, there is some difference between male and female femur.

What is Male Femur?
Male femur is the longest, strongest and heaviest bone in the male skeleton. Male femurs are heavier than female femurs. And also male femurs are lengthier and robust than the females. Thus, the average adult male femur is 48 centimetres (18.9 in) in length and 2.34 cm (0.92 in) in diameter. Since it is strong as a concrete, it can support up to 30 times the weight of an adult.
The degree of the inclination is lesser in males. Furthermore, male femurs are less angled than the female femurs. Therefore, the occurrence of the third trochanter is less common in males.
What is Female Femur?
The female femur is the strongest and longest bone in the female skeleton. There are two female femurs. Female femurs are generally shorter and less robust than the male femurs. And also they are often more angled than in men. Femurs occupy a slight X shape in females. The incidence of the third trochanter is frequently reported as more common in females than in males.
The female femur has an average length of 17 to 18 inches and an average diameter of 1 inch. The average weight of an adult female femur is 261 g. Similar to the male femur, the female femur is also able to support 30 times the weight of the body.
What are the Similarities Between Male and Female Femur?
- Male and femurs are the strongest, longest and heaviest bones in the human anatomy.
- They have similar parts and perform similar functions in the human body.
- Both are present in pairs.
What is the Difference Between Male and Female Femur?
Male and female femurs are the strongest and longest bones in the males and females respectively. Male femurs are heavier and longer than female femurs. And also the diameter of the head is higher than the female femur. The below infograph presents more details on the difference between male and female femur.
Summary – Male vs Female Femur
Femur is the strongest and longest bones in the human skeleton. Male femurs are stronger, longer and robust than the female femurs. Furthermore, the diameter of the head of male femurs is higher than the female femurs. This is the difference between male and female femur.
