Es geht im Fall Caster Semenya (hier vor dem Start eines eines Geschlechts, sondern um den großen Unterschied zwischen Frau und Mann.
The case was brought to CAS by Semenya, as she argued discrimination linked to a decision preventing some women, including herself, from competing in some female events.
This ruling is flawed. Semenya underwent medical testing in : at the time she was told it was a doping test. The results are confidential, but it has been widely reported that she does have an intersex condition.
These do not descend from the abdomen but do produce testosterone. However the receptors for testosterone are abnormal, with the result that the individual develops as female with a vagina, but no ovaries or uterus.
Circulating testosterone may have no biological effect in the case of complete androgen insensitivity syndrome AIS , or some effect in partial AIS.
Sex refers to biology, and gender refers to social role or self-identification. In sport, the definition of male and female used to be based solely on sex.
Sex determination was abandoned in the s in favour of gender. From the Sydney Olympics forwards, there were no tests of gender other than self-identification.
She is legally female, was from birth raised as female and identifies as a female. So, on the current definition, Semenya is a female.
Indeed, there has been no question of her gender. Sex determination itself is not simple, with chromosomal, gonadal presence of ovaries or testes , or secondary sex characteristics physical all possible definitions that would include or exclude different groups.
Geneticist Jenny Graves explains. This reverts back to the old biological categories. But Semenya is a female by the rules used by the International Association of Athletics Federations IAAF — so she should be allowed to compete to the best of her potential in her category.
An alternative is to retreat to the old sex-based definition based on the presence of a Y chromosome. But that carries its own questions on definitions, and also comes at great political and individual cost.
It would imply that Semenya is a male with a disorder of sexual development. But the CAS decision does not cover all forms of hyperandrogenism.
It only refers to women who have XY chromosomes, such as partial androgen insensitivity syndrome AIS. It does not cover a condition called congenital adrenal hyperplasia , which can cause elevated levels of testosterone in women with XX chromosomes.
The significant problem in partial AIS is that although testosterone is elevated in the blood, the receptors for testosterone do not respond to the hormone in the usual way.
That is why these individuals have typical external female physical characteristics. While the testosterone may have some impact on how the body works, it is impossible to quantify how much effect it is having.
The study on which the current decision is based contains only correlations and is flawed in several ways, with a call for its retraction on scientific grounds.
It is a single study, conducted by the IAAF and the full data have not been released for independent replication. Her body has grown up in the presence of a certain level of testosterone of uncertain function.
Our bodies are complex, and still poorly understood. A change of this kind may lead to unexpected results.
Some of these reductions in functions may be unjust. No one has given a complete description of the role of testosterone in someone like Semenya, nor how much it ought to be reduced to achieve a supposedly fair outcome.
The comparisons are only with XX chromosome women, who have a very different physiology and normal functioning testosterone receptors.
The science around testosterone in intersex conditions is poorly understood, let alone as it applies to individuals. This is a level chosen for convenience, not a level that will negate any perceived advantage, but go no further.
Yet Semenya is asked to cobble her natural potential as a female competitor. She must take risky biological interventions to reduce her performance.
Other women with disorders resulting in higher than expected levels of testosterone, such as congenital adrenal hyperplasia, are not required to reduce their biological advantage.
