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.
There are behavioral differences between males and females that may suggest a difference in amygdala size or function. A 2017 review of amygdala volume studies found that there was a raw size difference, with males having a 10% larger amygdala, however, because male brains are larger, this finding was found to be misleading.
Differentiation between the sexes of the sex organs occurs throughout embryological, fetal and later life. In both males and females, the sex organs consist of two structures: the internal genitalia and the external genitalia. In males, the gonads are the testicles and in females, they are the ovaries.
The most obvious differences between males and females include all the features related to reproductive roles, notably the endocrine (hormonal) systems and their physiological and behavioral effects, including gonadal differentiation, internal and external genital and breast differentiation, and differentiation of muscle mass, height, and hair ...
Phenotypic differences between sexes are evident even in cultured cells from tissues. [132] For example, female muscle-derived stem cells have a better muscle regeneration efficiency than male ones. [133] There are reports of several metabolic differences between male and female cells [134] and they also respond to stress differently. [135]
The differences between males and females in the context of childhood play is linked to differences in gender roles. A research on the "acquisition of fundamental movement skills" found that even though the level of mastery for certain skills were about the same for both boys and girls, after a certain age boys have better object control skills ...
Furthermore, indiscriminate use of the word gender tends to obscure the distinction between two different topics: (a) differences between males and females, and (b) individual differences in maleness and femaleness that occur within each sex. [122]
Various researchers have conducted studies to determine the differences between males and females and their abilities within their short-term memory. For example, a study conducted by Lowe, Mayfield, and Reynolds (2003) examined sex differences among children and adolescents on various short-term memory measures.
