- Biological Influences - Genes and Hormones
- Genetics
- kleinfelters syndrome
- Chromosome pattern of XXY instead of usual XY in males
- characteristics
- taller than usual
- larger breasts
- usually infertile
- shyer and more placid than usual men
- Money - David Reimer
- born as a boy but raised as a girl after his penis was destroyed during circumcism
- Money reported gender reassignment as successful
- never felt in the right body and preferred to be like his brother
- failed to live as a female bertween ages f 9 - 11 and by age of 15 began to live life as a male
- committed suicide at the age of 38
- failed to live as a female bertween ages f 9 - 11 and by age of 15 began to live life as a male

- kleinfelters syndrome
- Hormones
- Gorski
- unborn female rats exposed to male hormones in utero
- this led to the rats being more aggressive, showing boy boyish characteristics
- Scientific, shows cause and effect however its a animal study so may not be generalised towards humans
- this led to the rats being more aggressive, showing boy boyish characteristics
- unborn female rats exposed to male hormones in utero
- Money
- girls overexposed to male hormones in utero due to antisickness drug
- showed more tomboyish behaviours
- however, due to judgement which is unreliable as researched through interviews where leading questions may be used. only show a correlation
- showed more tomboyish behaviours
- girls overexposed to male hormones in utero due to antisickness drug
- Quadagon
- female monkeys given male hormones in womb.
- when born play was more rough than other females + were also more aggressive
- female monkeys given male hormones in womb.

- Brain Differences
- differences can be seen in size and function of the hypothalamus
- Swaab -'sexually dimorphic nucleus' in the hypothalamus
- analysed 13 men, 18 women, aged between 10 - 93
- found that the volume of the 'sexually dimorphic nucleus' is 2.5 times larger in men
- analysed 13 men, 18 women, aged between 10 - 93
- Swaab -'sexually dimorphic nucleus' in the hypothalamus
- young - rat study
- female rats given male hormones
- found the 'sexually dimorphic nucleus' to be larger than unaffected female rats
- female rats given male hormones
- study found that when carrying out a language based task, women use both sides of the brain where as men only use one side
- differences can be seen in size and function of the hypothalamus
- correlation studies
