Very unwilling to engage in a discussion with mehmet regarding this issue.
But for everyone else who may be interested, biological sex is not as clear cut as most people would think.
What determines sex comes down to genetics (your X and Y chromosomes), and hormones during development. So many things can go wrong. There are XO, XX, XY XXY, XXX, XYY etc. Then there are receptors and glands that may malfunction and the hormones don't achieve their effect, leading to different developmental routes. And sometimes only at puberty do parents/the person themselves find out that their biological sex is less clear cut than they thought. At this point they sometimes go through hormone therapy to keep their bodies looking like a certain sex to fit in with their gender identities (what they believe themselves to be). Quoting completely from memory I think the rate of occurrence is around 1 in 500-600 (keeping in mind that this number only calculates those detected at birth). You can find info about this in any embryology textbook. These problems are not apparent until puberty, so their gender is determined by the way they were raised. There are also cases where it is obvious at childbirth, and parents, like Psykhronic mentioned, often opt to surgically "correct" then into either male or female genitals. I think a lot of parents do this because they worry their child won't be able to grow up happy without a gender identity.
It's not easy for people with ambiguous biological sex to be in this society that likes to force people into black or white. It's even harder when they grew up with a strong gender identity only to find that they belong to the opposite sex when they're fourteen. All this is unnecessary, "they"'re not all that different from "us". Some can go their entire life without even knowing their chromosomes aren't XX or XY but something else.
