Just on this whole transgender athlete thing ...
My son has Klinefelter syndrome - also known as XXY Syndrome.
For those unaware, it means he is born with an extra X chromosome.
This means his body will naturally produce less testosterone through puberty, and his body's fat distribution will be more feminine (ie: more in the hips, and chest, and he will have narrower shoulders).
There is also a high chance that he may be naturally sterile.
When he's older, we will talk to him to see if he wants to have testosterone therapy (totally his choice, if he doesn't want it, it won't change the person he is).
Perhaps the Algerian fighter has Turned Syndrome?
I do think that the idea needs to be examined, though - we don't want to be in a position whereby the Algerian fighter is punished for having a genetic advantage, but we also don't want to be in a position where someone gets seriously hurt due to the genetic advantage.
It's a complex issue.
