Two years ago , at the 2009 World Championships , South African runner Caster Semenya bring home the bacon the gold medal in the women ’s 800 - meter race . Her festivity did n’t last long , however .
Citing Semenya ’s meteorological climb in the world standing , the rivalry ’s innkeeper , the International Association of Athletics Federations ( IAAF ) , had test her for performance - raise drugs in the weeks leading up to the backup . Controversially , it also subject her to a sex verification trial before the race — private information that was then publicly leaked just hours before her final race .

The outcome of the test were never let out and , in the end , she was allowed to run and , later , to keep her gold decoration .
This weekend , as Semenya defends her title at the 2011 IAAF World Championships in Daegu , Korea , Life ’s Little Mysteriesasks : How does the IAAF define sexuality , and does it line up with scientific discipline ?
The short resolution : not even science intelligibly determine it .
According to Anne Fausto - Sterling , a prof of biological science and sex at Brown University , there are multiple layers to sexual urge , include venereal , chromosomal and hormonal . While the layers for the legal age of the population align with the categories that we consider male and distaff , 1 to 2 percent are not so easily described .
" There is no one right definition , " bestow Fausto - Sterling . " You have to expect at it developmentally and you have to understand that there are multiple layer to sex and sexual urge determination . We do n’t normally see those multiple layers because they normally have given sort of the same substance to the body . But there are cases where some layers get one content and others get another message . "
Name the layer
Here are some basics . Usually , a male has a penis and nut . Chromosomally , he is XY , and hormonally he make more androgens , including testosterone . female , on the other hand , typically have a vagina , uterus and ovary , have XX chromosome and produce more estrogen .
But , there are a number of conditions where the element are jumble . weigh Swyer syndrome , for example , in which a person who expect distaff on the outside has XY chromosomes and no officiate ovary or testes . Or , innate adrenal hyperplasia , which can push the adrenal gland to produce such eminent levels of androgens as to make a person with XX chromosomes and ovary appear , from the outside , male .
And this is where scientist , and the IAAF , hunt down into trouble : Which marker — external appearance , chromosomes or internal secretion levels — check a person ’s sex ?
Scientists and doctors have tried to thread the virile / distaff line for centuries , say Alice Dreger , professor of clinical medical humanities and bioethics at Northwestern University ’s Feinberg School of Medicine , move from genital identification to chromosomal examination , and more recently to hormonal testing . But , because the layers are so complicated , each test at last fail : " It go down aside all the fourth dimension because as soon as you come up with a definition that seems fulfil , you rule someone who does n’t fit that definition . Nature is too complicated for just two categories to be based on biology . " [ What If There Were More Than Two Sexes ? ]
gender in fun
One reason why the IAAF scrutinizes sex is because eminent levels of androgens could give distaff athletes an edge , for example by helping work up stronger brawniness or fast chemical reaction times . ( Indeed , androgen - boosting drug are often the root word of fail performance - raise drug tests . )
So , how does the governing body define sex activity ? Not very well , it turns out . The IAAF does n’t require a gender psychometric test ( which they call gender testing , a misnomer becausegender and gender are not interchangeable terms ) . But , according to the IAAF Policy on Gender Verification , if an athlete ’s sex activity is challenged — for instance , by another competitor — they must undergo a barrage of psychometric test by a medical squad incorporate of a " gynecologist , endocrinologist , psychologist , intimate medicine specialist and expert on gender / transgender issues . "
The IAAF is also working to lay out up novel rules concerning innate hyperandrogenism in female , also make out as high-pitched grade of androgens . These rules are expected to be hammered out in the come months .
Despite the broad control board and potential new regulation , Dreger said there are inconsistencies in the IAAF ’s policy . woman with androgen - producing tumors , for deterrent example , are allowed to compete in woman ’s events despite the fact that they have elevated grade of the endocrine .
And , why single out hormones in char at all : human who have higher - than - average level of androgens , for instance , are not disqualified from competing against other men , she suppose . Other biologic advantage — superlative , for example — do not unfit athletes from competition , Dreger added . Why should internal secretion levels ?
irrespective of how the IAAF defines sexual practice , though , Dreger said it should come up with clearer policy so that jock know what they ’re catch into before they sign up to vie .
" Without a clear policy , masses are entering into a system that ’s an ' I know it when I see it ' kind of policy , and they ’re going to get caught over and over again in this problem where they are come out of the closet as sexually anomalous . And it can really ruin your life when that materialise because of the attitudes that people have . "
