A gender identity that displays a balance of masculine and feminine traits, an appearance and personality that can't be easily described as 'male or female'
Testosterone: Controls development of male sex organs and secondary sexual characteristics, linked to aggression (females produce it as well)
Oestrogen: Primary female sex hormone, regulation of the reproductive system and menstrual cycle and the development of secondary characteristics
Oxytocin: Love and bonding in males and females, higher in females due to oestrogen in the bloodstream, produced by the hypothalamus and released via the pituitary gland
High prenatal levels of testosterone which causes ambiguous genitals in females, individuals described as masculinised, suggesting testosterone is at least partly responsible for gender differences in behaviour
Children in Dominican Republic identified as girls at birth, testes didn't develop outside the body due to dihydrotestosterone missing in the womb, at age 12 testes developed properly, they were identified as boys
Individuals are physically shorter, have a broader chest, underdeveloped/unstereotyped ovaries, lack of menstruation, don't go through "typical" puberty, have lower life expectancy
Individuals have less facial and body hair, are less muscular, have delayed puberty, have lower testosterone levels, have broader hips, have longer legs
Treatment for Klinefelter's Syndrome has shown improvements in behavioural and language problems associated with the disorder, as well as muscle development, facial hair, and deeper voice
Cognitive developmental explanation that gender develops with age (similar to Konibeng), children actively structure their own learning rather than passively observing imitating (SLT)
