There is no conclusive evidence that sex
change operations improve the lives of transsexuals, with many people
remaining severely distressed and even suicidal after the operation,
according to a medical review conducted exclusively for Guardian Weekend
tomorrow.The review of more than
100 international medical studies of post-operative transsexuals by the
University of Birmingham's aggressive research intelligence facility (Arif)
found no robust scientific evidence that gender reassignment surgery is
clinically effective.
The Guardian asked Arif to conduct the
review after speaking to several people who regret changing gender or
believe that the medical care they received failed to prepare them for
their new lives. They explain why they are unhappy with their sex change
and how they cope with the consequences in the Weekend magazine tomorrow
(July 31).
Chris Hyde, the director of Arif, said:
"There is a huge uncertainty over whether changing someone's sex is a
good or a bad thing. While no doubt great care is taken to ensure that
appropriate patients undergo gender reassignment, there's still a large
number of people who have the surgery but remain traumatised - often to
the point of committing suicide."
Arif, which advises the NHS in the West
Midlands about the evidence base of healthcare treatments, found that
most of the medical research on gender reassignment was poorly designed,
which skewed the results to suggest that sex change operations are
beneficial.
Its review warns that the results of
many gender reassignment studies are unsound because researchers lost
track of more than half of the participants. For example, in a five-year
study of 727 post-operative transsexuals published last year, 495 people
dropped out for unknown reasons. Dr Hyde said the high drop out rate
could reflect high levels of dissatisfaction or even suicide among
post-operative transsexuals. He called for the causes of their deaths to
be tracked to provide more evidence.
Dr Hyde said: "The bottom line is that
although it's clear that some people do well with gender reassignment
surgery, the available research does little to reassure about how many
patients do badly and, if so, how badly."
There are around 5,000 post-operative
transsexuals in the UK, according to the transgender pressure group
Press for Change (PFC). It is estimated that up to 400 sex changes will
be performed this year on the NHS and privately. Each operation costs
the NHS around £3,000, while private patients pay upwards of £8,000 for
surgery.
Christine Burns, of PFC, said the
campaign group's research suggested that the vast majority of
transsexual people enjoyed much happier lives following surgery.
Ms Burns added that the greatest flaws
in medical literature about gender reassignment were in those studies
unsympathetic to transsexual people. For example, one study was based on
a survey of seven transsexual prostitutes interviewed in one gay bar in
Chicago.
She said: "The fact that research is
badly constructed isn't a poor reflection on transpeople, but on the
people we should be able to trust for our care. If they "lose" half the
patients they ought to be able to track the question is why? As we've
repeatedly pointed out ourselves there is really no difficulty in
getting transpeople to come forward and cooperate in research that is
properly constructed and conceived with people's true well-being in
mind."
Research from the US and Holland
suggests that up to a fifth of patients regret changing sex. A 1998
review by the Research and Development Directorate of the NHS Executive
found attempted suicide rates of up to 18% noted in some medical studies
of gender reassignment.
Andrew McCulloch, chief executive of
the Mental Health Foundation, has written to the mental health minister,
Rosie Winterton, requesting a "thorough assessment" of the long-term
effects of sex change operations. He wants the National Institute for
Clinical Excellence, which decides what treatments should be available
on the NHS, to draw up guidelines on gender reassignment.
Transgender psychiatrists, who assess
whether patients should change sex, agree that more scientific research
is needed. But Kevan Wylie, chairman of the Royal College of
Psychiatrists' working party on gender identity disorders, said that all
of his patients' lives have drastically improved following gender
reassignment surgery.
Dr Wylie added that it was difficult to
conduct research on the outcome of gender reassignment, or to compare
its effects with alternative treatments, because transsexualism was such
a "rare experience". Urological surgeon James Bellringer, who has
performed more than 200 sex changes over the past four years, claimed
that trying to carry out research that involves studying a control group
of transsexual patients who were denied hormones and surgery would be
unethical.
Mr Bellringer, who works at the main
NHS gender identity clinic at Charing Cross hospital in west London,
said: "I don't think that any research that denied transsexual patients
treatment would get past an ethics committee. There's no other treatment
that works. You either have an operation or suffer a miserable life. A
fifth of those who don't get treatment commit suicide."
