For those who say: Doctor's should follow the oath and 'do no harm'. I doubt the physician intentionally thought 'let me screw this kid up', but hey, you're entitled to your opinion.
Second, who says the couple is not looking for money? That's always a possibility. Sometimes it is even absurd what people sue for. Many say they weren't informed of ALL the potential complications...Jesus Christ, first of all, there is no way to prove they were not informed of ALL.
Ok, let's say, in this case they are right. Now the kid is showing so called 'male behavior'. What if the kid is a lesbian?????? (I'm sure the 'understanding and loving' parents won't consider that because, in the end, it won't bring them money). So I dare the couple to sue and ask for a benefit for the kid only (and not monetary), education, health insurance, something that will benefit the kid. Ah, now THAT they won't likely do...why? Because again, there's no money in that.
I do agree, however, with maybe waiting some time and letting the kid decide when he is older. Now that will take some years, and that same kid will have to endure abuse and mockery while in the showers in school and potentially end up making a big mistake. So it is a very delicate and fine line we walk on here.
Think of this: the same child was going to be adopted. I believe the state and potentially the physician had good intentions when they thought: this kid is going to be adopted, and by leaving his sex indeterminate we lower his chances (and chances are low as it is).
