Yes, but she's a male (xy chromosome) who doesn't respond properly to male androgen, so developed as a woman, albeit she is only partially insensitive, so developed partly male.
Well she didn't really develop as a woman she just didn't properly develop a male penis and her balls didn't drop and so has been identified as a woman pretty much since birth...
Semenya seems to have partial androgen insensitivity, so has developed, to some extent, some secondary female characteristics like breasts and hips, but has also developed some secondary male characteristics, like a deep voice and muscle mass. She gets some benefit from testosterone, but not as much as a man would.
What is that based on?
The below is from that runners forum related to the article posted - Serena is a female who has had some rather silly conspiracy theory like accusations of being male in the past and some defenders of Caster seem to be under the impression that she's suffering from the same criticism and is just a strong African woman etc...
I don't see the hips or breasts you're referring to though on Caster, Serena on the other hand, a biological woman, clearly does have them.
