The favorite in the women's 800m at the world track championships will run under suspicion that she's actually a man.

After bursting onto the scene with the world's fastest time three weeks ago at a junior meet, South Africa's Caster Semenya, 18, has been dogged by gender-swapping accusations. She will undergo complex gender testing (it's not as easy as you'd think) after her race tonight, but the results won't be available for a few weeks. Semenya had the fastest qualifying time of the eight competitors. 

South African officials have acknowledged the controversy, but are standing by Semenya. Molatelo Malehopo, general manager of Athletics South Africa, told UK's Daily Mail:

"She is a female. We are completely sure about that and we wouldn't have entered her into the female competition if we had any doubts.

We have not been absent-minded, we are very sure of her gender. We are aware of the claims that have been made but our aim at the moment is to prepare Caster for the race this evening."

It's nothing new for a great female athlete to be accused of being a man. Babe Didrikson, perhaps the greatest sportswoman of all-time, was constantly being hounded by such slurs. And it's also not unheard of for a man to compete as a woman. 

But despite the breathless reports from British and Australian newspapers, there doesn't seem to be any concrete evidence that Semenya is actually a man other than the fact that she runs really fast, has a defined physique and doesn't have the most feminine of features. 

It's interesting that the speculation immediately turned to gender rather than steroids, as the latter would be a more logical way to cheat. Normally when athletes lower their personal bests by wide margins, the talk immediately turns toward doping. Not in this case.

And if Semenya was actually a man, wouldn't he/she try to do more to look like a woman? I mean, I've seen Tootsie. Dustin Hoffman didn't go into that TV studio with a buzz cut and form-fitting pants. He put on a dress, teased the hair and wore nail polish and makeup. He sold it. If Semenya was trying to switch genders, wouldn't there be some more effort to glam it up?

The whole thing is pretty insulting and I feel bad for the 18-year old that is getting dragged through this. Maybe she's a he. If that's proven, then I'll be first in line to criticize. But right now there's nothing to suggest that there's anything nefarious going on other than the jealous whispers of competitors.

Update: If there were whispers before, they'll likely turn to shouts now. Caster Semenya thoroughly dominated the field in the 800m final tonight in Berlin, hitting the tape a full 25 meters ahead of the field.

While the other runners were laboring in the backstretch, Semenya looked like she was out for a Sunday jog. Her 1:55.46 was the fastest winning time at the world championships since 1993.

And not that this means anything either way, but when Semenya raised her arms in triumph after the race it was clear that she doesn't shave her armpits. To go back to the Tootsie comparison, if Semenya is actually a man, she/he isn't trying very hard to mask it.

The IAAF insists that the gender testing of Semenya is a "medical issue" not one of foul play.
