The neuroscience of sex differences is the study of characteristics that separate brains of different sexes. Psychological sex differences are thought by some to reflect the interaction of genes, hormones, and social learning on brain development throughout the lifespan. A 2021 meta-synthesis led by Lise Eliot found that sex accounted for 1% of ...
Being exposed to female ovulating cues may increase testosterone, which in turn may increase males' motivation to engage in, and initiate, sexual behaviour. Ultimately, these higher levels of testosterone may increase the reproductive success of males exposed to female ovulation cues. The relationship between testosterone and female sexual ...
In a female, on the other hand, absence of these levels of androgens results in development of typically female genitals. [4] Following this, sexual differentiation of the brain occurs; sex hormones exert organizational effects on the brain that will be activated in puberty. [ 4 ]
The human brain. Differences in male and female brain size are relative to body size. [82] 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.
In mice, prenatal testosterone transfer causes higher blood concentrations of testosterone in 2M females when compared to 1M or 0M females. [6] This has a variety of consequences on later female behavior, physiology, and morphology. Below is a table comparing physiological, morphological, and behavioral differences of 0M and 2M female mice. [1]
A review of retrospective studies that measured gender nonconforming traits estimated that 89% of homosexual men exceeded heterosexual males level of gender nonconformity, whereas just 2% of heterosexual men exceeded the homosexual median. For female sexual orientation, the figures were 81% and 12% respectively.
Testosterone is used as a medication for the treatment of male hypogonadism, gender dysphoria, and certain types of breast cancer. [ 13][ 54] This is known as hormone replacement therapy (HRT) or testosterone replacement therapy (TRT), which maintains serum testosterone levels in the normal range.
e. Sex differences in psychology are differences in the mental functions and behaviors of the sexes and are due to a complex interplay of biological, developmental, and cultural factors. Differences have been found in a variety of fields such as mental health, cognitive abilities, personality, emotion, sexuality, friendship, [ 1] and tendency ...
