Atypical gender development
Gender identity disorder (GID)
Experience a mismatch between their biological sex and they 'feel' they are
Identify more with the opposite sex rather than then one they were identified as at birth
Recognised as a psychological disorder and in DSM-5
Will identify themselves as transgender and may opt for gender reassignment surgery
Main
theories
Biological explanation
Social-psychological explanation
Biological explanations : brain sex theory , genetic factors
Brain sex theory:
GID caused by brain structure that are incompatible with a persons biological sex
Transsexual brains dont match the genetic sex assigned at birth e.g. male brain in a female body
Focusi on areas of the brain that are different in males and females (dimophoric))
Zhou
BSTc-40% larger in males than females assumed I be fully developed by age 5
Post-mortems of 6 male to femaletransgender individuals-BTSc was similar size to that in females
Number of neurons in the BSTc showed a sed revered identity pattern with an average BSTc number in the female range
Number of neurons in the BSTc showed a sex revered identity pattern with an average BSTc number in the female range
Genetic factors
Transexual gene – individuals with GID have a genetic variation
Hare
112 m-to-f transexuals
Majority had longer versions of the androgen receptor gene
Means testosterone had a reduced effect – this affects prenatal development
Results in under development of a masculinised brain, causing the development of GID later in life
