Atypical gender development Flashcards
What does the DSM-V classify it as
gender dysphoria (mismatch between biological sex and the gender they feel they are)
Stats in the UK
M>F:F>M= 5:1
Diagnosis points for gender dysphoria
Affects the ability to function with everyday life
Sense of discomfort with biological sex
Ongoing identification with opposite sex
No biological disorder at the same time
Symptoms for 6 months
Children but be able to verbalise.
biological explainations
Brain sex theory
Phantom-limb (cross wiring)
Evidence from amputations
Brain sex theory
GD is caused by physical structures of the brain not matching typical structures of the brain
Looks at dimorphic areas
BTSC is found in the thalamus and is 40% larger in males.
Brain sex theory research
Zhou (post mortems in M>F)
BSTC similar size to cisgender women which suggests a female brain in a mens body
Brain sex theory limitation
Suggests that BSTC cannot be effected by hormones as it is fixed. Hulshoff pol et al. found hormone therapy affects the size of BSTC so causation is an issue.
Phantom limb
Ramachandran suggets GD is a form of phantom limb syndrome but for genitalia
Phantom Limb research support
2/3 of F>M report phantom penis sensation from childhood.
Phantom limb strengths
Evidence from amputations
60% of men without GD who have penis amputations experience phantom penis, 30% of M>F do.
Genetic explanations
Evidence shows that a longer version of the androgen receptor in M>F transexuals may reduce prenatal testosterone causing under-masculinised brains in the foetus.
Genetic explainations research support
Heylins found that 9/23 MZ twins had a co twin with GD, (0/21 for DZ twins.)
Genetic explainations limitations
Twin studies cannot split nature/ nurture and small sample sizes make it hard to genderalise.
Biological explainations general evaluation
Reductionist- presence of higher factors like interaction with environment are disregarded.
Psychological explainations
Cognitive explainations, mother/son relationships.
