After reading this -
"So Semenya has a genetic advantage, by virtue of A) having a Y-chromosome and testes, and B) being unable to use that T and/or one of its derivatives enough to have developed fully male.
In that regard, if you approached it from the other direction, you could, relatively accurately, say that Semenya has a disadvantage compared to other males with XY and testosterone, because unlike them she cannot fully use T (and/or a derivative – depends on the exact condition)."

I'm inclined to suggest that the "fairest" option is to allow her to compete in the Paralympics as a male.
