Imagine that one day for whatever reason, athletic competitions, et cetera, you take a medical test that you expect will confirm what you know and have deeply felt since birth. You were raised as female, you have no doubts about your gender identity, and your body and your reflection in the mirror confirm that.
Now imagine how you would feel if the results of that gender test aren't quite what you expected.

Then her chromosome test came back. Because she had "one chromosome too many," she was a man*.
She was stripped of her world record, her Olympic medal and barred from international competition.
A year later it was Erika Schinegger's turn. In 1966 she'd become the World Cup skiing champion and subsequently a national shero in that skiing mad country.

Turns out Erika was chromosomally male due to an intersex condition. That condition was missed at birth and she was raised as a girl. After discovering this information, Erika transitioned to become Erik, competed on the men's skiing tour for a few years, married in 1975 and now runs a ski school.

She failed it after discovering she had androgen insensitivity syndrome (AIS) and was a woman with 46XY chromosomes.
The failed test had devastating and humiliating consequences in Patino's life. Not only was she barred from competing for several years, she lost an athletic scholarship, watched her boyfriends walk out of her life and ultimately, the chance to compete in the 1992 Olympics being hosted in her country.

Patino retired from athletics, picked up her PhD and is now an university professor.
Santhi Soundarajan was an up and coming runner who held the Indian national record in the 3000m steeplechase and was the 800m silver medalist at the 2005 Asian championships.
Her world as she knew it came to an end after she repeated her silver medal winning performance at the 2006 Asian Games in Doha, Bahrain. She underwent a gender test and failed it.

So as South Africa's Caster Semenya and the world awaits the results of the gender test, it is with this backdrop of negative history what her potential fate will be if it comes back with a negative result. At the same time, it also lets her know that there is life after a adverse gender test.
But it points out once again that in humans, there is a extremely fine line hormonally that separates male from female.
It's past time we recognize that.
