There seems to be two issues here.
- Should she be allowed to compete with ordinary females? Note: I said ordinary (the most neutral term I know), rather than normal, which seems a bit more biased. I think the answer to this question is no, but the issue seems a bit muddy at best. Would we allow a female competitor to take testosterone or other steroids to enhance her physical abilities? As of now, the answer to this question is no because it is viewed as giving an unfair advantage. Hence it would seem that we should disqualify a female with high levels of testosterone due to an unusual biochemisty.
This issue is a bit muddy because we would not disqualify a male who happened to have an unusually high level of testosterone due to his having an unusual body chemisty. We do not disqualify either male or female athletes due to having some advantage bestowed on them by their genetic heritage. It would be a nightmare if we tried to have many levels of competition based on body chemistry, although we readily accept boxing & wrestling competitons with divisons based on body weight.
- Should she be required to make a choice & be forced to have the appropriate surgery & other medical procedures to make her body chemisty & anatomy more closely approximate one sex or the other? The answer to this question cannot be other than no. It would be outrageous to force surgery or other medical procedures on a rational adult who wanted to live as is.
Interesting enough, one of my college friends recently died because he refused to take the advice of his cardiologist. He decided he would rather die or have a heart attack than give up tennis & other strenuous activities he loved. Jackie Onassis decided to stop taking Chemo-therapy because she decided that a shorter life without the side effects of the therapy was preferable to a longer life with the bad side effects.
