During elbow extension, however, the oblique posterior part makes contact with the trochlear notch on the ulna so that this obliquity forces the main axis of the forearm to form a small angle with that of the upper arm. This angle is known as the carrying angle and is more prominent in women than in men. [3]
The carrying angle permits the arm to be swung without contacting the hips. Women on average have smaller shoulders and wider hips than men, which tends to produce a larger carrying angle (i.e., larger deviation from a straight line than that in men). There is, however, extensive overlap in the carrying angle between individual men and women ...
The sacrum in females is shorter and wider, and also directed more toward the rear (see image). [10] This sometimes affects their walking style, resulting in hip sway. [11] The upper limb in females have an outward angulation (carrying angle) at elbow level to accommodate the wider pelvis. After puberty, hips are generally wider than shoulders.
A small degree of cubitus valgus (known as the carrying angle) is acceptable and occurs in the general population. [citation needed] When present at birth, it can be an indication of Turner syndrome [1] or Noonan syndrome. It can also be acquired through fracture or other trauma. The physiological cubitus valgus varies from 3° to 29°.
The brains of pregnant females carrying male fetuses may be shielded from the masculinizing effects of androgen through the action of sex hormone-binding globulin. [114] The relationship between sex differences in the brain and human behavior is a subject of controversy in psychology and society at large.
The human brain. Differences in male and female brain size are relative to body size. [83] Early research into the differences between male and female brains showed that male brains are, on average, larger than female brains. This research was frequently cited to support the assertion that women are less intelligent than men.

For short stature, growth hormone is sometimes combined with IGF-1 (or as an alternative, IGF-1 as a stand-alone) can be used to achieve an increased height/final height quicker. The final adult height of individuals with Noonan syndrome is about 161–167 cm in males and 150–155 cm in females, which approaches the lower limit of normal. [8]
