according to your text book
by about 18 months
most children have developed a firm gender identity
1950s-1970s
John Money and colleagues
believed that a person is born
psychosexually neutral or undifferentiated
and social-learning
experiences
are the essential determinants of
gender identity and gender-role
behavior

the child raised as a girl
first stage surgical feminization at age 2
medically unremarkable childhood
except for taking daily cortisone
breast development began at 13
menses began at 20
developed behaviorally as a girl
with tomboyish activity interests
not conspicuously different from other girls of her age
In teenage, academic and career
interests had priority over dating, romance, and going steady
There was no romantic inclination toward
either boys or girls, but rather a projection into the future of the boyfriend
and married state of life
Otherwise, everything about this girl
was very attractively feminine to all who interviewed and knew her
the child raised as a boy
at birth and pronounced a male
with a hypospadiac phallus and undescended testes
3 stages of surgical masculinization
ended in failure
urine backed up into the internally opening vagina
with ensuing infection
correct diagnosis established at age 3 ½
child was terror stricken at being once again in a
hospital
using clay he was shown how a penis could be repaired
during childhood cortisone therapy
permitted statural growth to be
normal
at the age of puberty
masculinization was induced by androgen therapy
artificial testes were implanted
the boy’s family life was tortured
in teenage, the boy was an academic underachiever
he achieved status of sorts as a rebel
he was accepted by the other boys as one of them
he was not overly aggressive
all of his romantic feelings and approaches
were towards girls despite his trepidation
at the prospect of attempting intercourse
with too small a penis and prosthetic testes

Stone: The True Story of John/Joan
both by John Colapinto
[picture of
book cover]
August 1965
Bruce and Brian Reimer born
April 1966 (8 mo)
Bruce suffered circumcision accident
Early 1967 Bruce’s parents
met John Money in Baltimore
Bruce “became” Brenda (17 mo)
July 1967 (22 mo) testes removed
rudimentary exterior vagina created
[picture]
1971-Money wrote a letter to Brenda’s
school urging promotion to 1st grade
Brian speaking of Brenda:
“When I say there was nothing feminine
about Brenda, I mean there was nothing feminine. She walked like
a guy. She talked about guy things, didn’t give a crap about cleaning house,
getting married, wearing makeup…We both wanted to play with guys, build forts
and have snowball fights and play army.”
[picture]
when Brenda daydreamed she saw herself as a 21-year-old
male with a mustache and a sports car
surrounded by admiring friends
by age 9
“Money told us that he had asked Brenda
what partner she would rather have, a boy or a girl,” [her father recalls].
“Brenda had said, ‘A girl.’”
[Her father] recalls that Dr. Money
wanted to know how they felt about raising a lesbian.
[picture]
by age 14
Brenda refused to wear dresses
she favored a tattered jean jacket ragged cords and work
boots
her hair was unwashed
uncombed and matted
she enrolled in an appliance-repair course
at a technical high school
classmates called her Cave-woman and Sasquatch
she switched to urinating from a standing position
Brendas psychiatrist and endocrinologist at the time
decided she should be told the truth about herself.
March 1980 – Brenda’s father told her
the truth
[picture]
he named himself David
demanded hormone treatments & surgery
(- breasts, + penis)
a girlfriend broadcast his secret
he entered a deep depression
he attempted suicide
he was introduced to his future wife
by his brother and sister-in-law
at age 25 he married a woman with 3 children
he landed a well paying factory job
he came out publicly with his story
to prevent similar sex reassignments
from happening to others

incidence of sex reassignments
US – 100 to 200 sex reassignments / year
globally – 1000 sex reassignments / year
in the 25 years following the Twin Study
as many as 15,000 similar sex reassignments
may have been performed
estimates given by William Reiner
as reported in John Colapinto’s
1997 Rolling Stone Article
John Money
pioneer sex researcher
developed protocols for treatment of intersex children
1972 book (co-author Anke
Ehrhardt) Man & Woman, Boy & Girl
1971 – Money intervened with Brenda’s
school (1st grade)
1972 – 1st published case
as unqualified success
1974 – Money told Brenda’s parents she
was probably lesbian
1976 – Treating psychiatrist relates
woes to Money
1978 – Money published in journal
“Now prepubertal in age, the girl has…a feminine
gender identity and role, distinctly different from that of her brother.”
[picture]
Milton (Mickey) Diamond
1965 – published
in The Quarterly Review of Biology evidence from biology,
psychology, psychiatry, anthropology
and endocrinology to argue that gender
identity is hardwired into the brain virtually from conception
yearly ad in the American Psychiatric Society Journal
“Will whoever is treating the twins please report.”
1991 contacted Sigmundson

then in private practice
Reiner treated young patients born with
irregular genitals
- often
constructing female external genitals for males with no penis or a micropenis

raised as a girl
tended to socialize with boys
as she got older she recognized her erotic orientation
was towards females

1993 – She founded the Intersex Society of North America (ISNA),
a peer-support, activist and advocacy group

contemporary model
the interactional model
human infants possess a complex and yet to be fully
understood biological substrate that predisposes them
to interact with their social environment in either a
masculine or feminine mode
life experiences
shape the way we think about ourselves - not only as masculine or
feminine
but in all aspects of how we relate to those around us
both biology and experience are important in the
development of gender identity
transsexual = a person whose gender identity
is opposite to his or her biological sex
transgendered - individuals whose
appearance and behaviors
do not conform to societal gender roles
gender dysphoria = a feeling of being trapped in a body
of the wrong sex.
the nature and cause of transsexualism
are not known
a male-to-female transsexual usually wants to be
desired
as a woman by a heterosexual man
psychotherapy, without accompanying biological alterations,
has generally been reported to be unsuccessful
in helping transsexuals adjust to their bodies
to qualify for a sex-change procedure
live for one year or more as the other sex
while undergoing hormone therapy
before taking the final, drastic step of surgery
cosmetically
male-to-female sex-change surgery
is usually more effective than
female-to-male sex-change surgery
most transsexuals are happy with their surgery
and would do it again if they could go back in time

1530 Spanish Explorer Cabeza de Vaca
saw male Native Americans in Florida dressing &
working as women
other explorers saw similar phenomena throughout North
America
cultural anthropologists have documented this “third gender”
status
in at least 120 North American tribes
[picture of third gender person]
“A berdache
was one who was defined by
spirituality, androgyny, women’s work and male/male homosexual relationships.
The berdache
could adopt the clothing of women, associate and be involved with women,
do the work normally associated with women, marry a man
and
take part in many spiritual ceremonies of the tribe.
Female
versions of the role also occurred,
but are less well documented…
A Native American Perspective on the
Theory of Gender Continuum by DRK
http://hermaphrodite.arriba.net/twospirit.htm
What’s the problem with ‘Berdache’?
“While ‘berdache’
is in common use among white gays, Native Americans find the term offensive
as it comes ultimately from the Arabic where it means
roughly, ‘male prostitute’.
We do not appreciate having our sacred
people referred to in this way.
The consensus of opinion is that ‘berdache’ should not be used and the tribal name should be
used when known.”

men as “sexperts”
men as teachers
responsible for success of encounter
impact – continued
women as controllers, men as movers
women controlling men’s “lust”
preserving “honor”
women as “sexual challenges”
