Nonsense argument. Let's unpack it:
Males have given birth naturally through the birth canal.
Before the discovery of chromosomes, we figured out the sex of a baby based on what genitals it was born with.
In this case, that of Swyers Syndrome, babies look unambiguously female. Their external sex is female, they also have a vagina, a functional uterus and fallopian tubes.
Problems arise in puberty, because what they don't have are sex glands (aka gonads aka ovaries or testes). They have what's called streak or fibrous scar tissue instead.
Because their bodies cannot produce sex hormones, these girls do not go through puberty at all. So, if we leave it to nature, nothing would happen at all.
But we don't leave it to nature, doctors prescribe these girls female sex hormones to allow their female reproductive organs and their secondary characteristics to develop. They go through puberty and start menstruating.
As they don't produce their own eggs, again, no pregnancy happens "naturally". But assisted fertility clinics can help these women to get pregnant. Their womb is fully functional and they can carry a baby to term. Vaginal birth may be difficult, however. Hence the c-section in this case.
This very rare DSD is actually a good example to explain why we don't determine sex based on sex chromosomes alone (which we've only been able to do for a fraction of human history in any case).
Today we look at
-chromosomes
-gonads
-sex organs and genitals
We don't look at a baby born with female genitals, raise her as female and then call her male when puberty doesn't set in. Besides, by nature, such a child has even fewer male attributes than female ones:
No male genitals
No male gonads
No male secondary characteristics
No male reproductive system
Yes, she has a y-chromosome. And she has:
Female genitals
Female reproductive organs
With hormone therapy, she also develops
Female secondary sex characteristics
Oger may choose to ignore the fact that in ambiguous cases sex is determined on the basis of several attributes. Or that using someone with a complex medical condition for a gotcha that doesn't even get us is low.
But the word "naturally" is spectacularly ill chosen here.
And most importantly, it continues to be the case that no male human has ever been pregnant and given birth. Whether naturally or otherwise.
