I'm pretty sure the sex of the intersex is determined by which genitalia work eg someone can be born with both testicles and a womb but the testicles may not work properly so they may remove the testicles and form a vagina for the child. Obviously every intersex case is unique to the individual but unfortunately rn no biological male can carry children, I hope one day that can change so guys can also go through childbirth like women.

Yeah you are right but intersex people doesn't have any biological sex.
As they grow up over time, they gain their own identity with the help of a psychologist. They can be pansexual, heterosexual,gay,lesbian etc. ...
Current medicine cannot determine the "real sex" of babies. So despite having XY chromosomes, most people born with androgen insensitivity syndrome live their lives as women, so chromosomes alone cannot determine a person's gender.
In other words, it can measure how big the clitoris is, but it cannot judge how big or wide it should be. This is a social determination.
So, with current technology, we cannot determine whether a person is a "man" or a "woman". (▰˘◡˘▰)
In a comment I saw something like "is it possible for a man to have a womb or give birth?" (idk which was it) ╮( ̄▽ ̄)╭
Yes it is really possible thing to a "man" having a womb. Actually we can't say person "man" or "woman". You guys know LBGTI. The I is for intersexual people. Intersexual people may have bodily and hormonal features of both a man and a woman. Intersexual people are not trans or hermaphrodites. (⊙..^..⊙ )
In fact, you may even know an intersexual person. 1.7% of the world's population is intersexual. I don't know exactly if a "man" can give birth, but he can have a womb and also testicles. ( ̄∇ ̄")
Anyway, that was all I just wanted to inform my friends. As a matter of fact, I have just learned. I was really surprised when I first found out. (sorry for my bad grammar and english) (≧∀≦) (づ ̄ ³ ̄)づ
