Just to agree with
@Mariposa Electrique and the fact fact my main reply said there's a chimera mostly XY woman who got pregnant and even produce her own eggs. And I also know many cases of XY gonadal dysgenesis that can be pregnant with donated eggs. Swyer is NOT androgen insensitivity. When the mutation of SRY gene happened, you got almost all of the female reproductive system just that the ovary isn't properly formed.
In the article about 'Women's without womb' getting pregnant. It's likely a misdiagnosis after XY karotype.. or perhaps that person mutation isn't just Androgen Insensitivity but also SRY or gonadal development related.. and in fact they would have a womb. The misdiagnosis is made into a title generate a clickbait...
If the mutation is Androgen Insensitivity alone they would NOT have a womb.
