I do feel for these women - for if they self-identify as women I am happy to call them women - but I do not think they should necessarily be permitted to participate in women's professional sports.
Because, from a biological (not social) perspective, they may in fact be male.
WHY professional sports bodies played the politics game instead of consulting medical professionals, I cannot say. Why it is okay to use the appearance of someone's external genitalia to decide what sex they are? This criteria is not only antiquated, but flat out wrong.
Some medical definitions:
1) male pseudohermaphrodite - Generally speaking, someone who has a vulva and clitoris but also has testicles. This person is medically MALE. Caster Semenya is a male, medically speaking, not a female.
2) female pseudohermaphrodite - someone who has a penis and the appearance of a male externally but actually has ovaries.
3) True hermaphrodite - both ovaries and testicles are present.
All of these conditions fall under the term "intersex" and what someone looks like externally has a lot to do with what hormones were around during a certain period of gestation.
Hyperandrogenism means too much testosterone. There are several causes of hyperandrogenism. Internal testicles is one cause. Other causes include Cushings disease, adrenal gland tumors, and polycystic ovarian disease in women. These other types of hyperandrogenism, due to the fact that people with them are typically ill, are probably not performance enhancing.
Why can the IAAF not just use the biological definitions of sex and leave it at that? And if there is any questions (for example, a true hermaphrodite), make them compete with the men.
YES it sucks that now these people will be publicly submitted to a barrage of tests. YES it can be humiliating. But public scrutiny is a price you must pay for the privilege of competing on the international stage.
