Caster Semenya's sex in doubt

By now, most of you will be aware that South Africa's 800m sensation, Caster Semenya, has been reported as a potential disqualification from tonight's 800m final in Berlin, on the grounds that the IAAF had conducted tests on her to establish her sex, and that she might be male (I must clarify this - it's not an issue of male vs female, but of "entirely female", since she may possess secondary male characteristics as a result of some condition, reported as hermaphroditism).

This latest report (unconfirmed, I might add, at least with respects to the DQ - apparently the testing was done) is the climax of rumors that have been doing the rounds ever since the 18-year set the world's fastest time of 1:56.72 in a low key meeting in Mauritius recently.
