I've been quoted at, sampled etc this morning... sadly by people who don't / can't / won't understand the science and keep repeating the same simplistic inaccuracies.
She is biologically a man... No, she really isn't, please take some time to read www.isna.org/faq/what_is_intersex
But in short, these are the reasons your statement that Semenya is a man are too simplistic and miss the point!
46, XX INTERSEX: The person has the chromosomes of a woman, the ovaries of a woman, but external (outside) genitals that appear male.
So, has a willy, but is female...
46, XY INTERSEX: The person has the chromosomes of a man, but the external genitals are incompletely formed, ambiguous, or clearly female.
May not have a willy, may have labia, but is a man.
TRUE GONADAL INTERSEX: The person must have both ovarian and testicular tissue. The person may have XX chromosomes, XY chromosomes, or both. The external genitals may be ambiguous or may appear to be female or male. This condition used to be called true hermaphroditism.
May have both, or neither, genitals, so....
COMPLEX OR UNDETERMINED INTERSEX DISORDERS OF SEXUAL DEVELOPMENT: Many chromosome configurations other than simple 46, XX or 46, XY can result in disorders of sex development - both cases have an extra sex chromosome, either an X or a Y. These disorders do not result in a condition where there is discrepancy between internal and external genitalia. However, there may be problems with sex hormone levels, overall sexual development, and altered numbers of sex chromosomes.
Looks like, walks and talks like... but has internal issues, may not be wholly either, or....
