Criticism of
BSTc
size and neuronal number
Chung
et al.
Significant
sexual dimorphism doesn't develop until
adulthood
However,
MTF
transgenders report their feelings start at
childhood
Therefore, it is unlikely that BSTc
volume
and
neuron number
can be a
neuroanatomical signature
identifiable with gender identity
Evidence for
genetic basis
Hare et al.
Transsexual gene
- a
longer
version of the
androgen receptor gene
Reduces sensitivity to
testosterone
,
under-masculinising
the brain
MTF
more likely to have this gene
Criticism for
brain scans
Marik
et al.
2000
participants -
25%
replicability
<
500
-
5%
Therefore, brain scans must be done with
large
sample sizes
Socially sensitive research
Removes
responsibility
from the person
Stigmatises
characteristics
Clinicians should avoid reinforcing damaging
stereotypes
