What's the closest number to zero that you can think of? It's that

But you specified biological sex, so essentially zero is the right answer.

It would seem to be that however small the risk might be it is not insignificant since the BBC recently highlighted cases of misdiagnosis and I find on looking for them that there is an american standard on the subject.

There are a number of genetic causes of intersex individuals, some of which render the physical attributes of the individual to be discordant with their underlying genetics (e.g. AIS resulting in XY individuals with undescended testes and a vagina, or CAH resulting in XX individuals with masculine traits). I imagine that these conditions - typically with frequencies of one in thens of thousands might contribute to discrepancies in the designation of biological sex at birth.

Thank you for that knowledgable amplification.
