The available literature shows only 14 cases of people with DSDs who had both ovarian and testicular tissue becoming pregnant. All of these individuals had a uterus, at least one functioning ovary and a vagina, otherwise pregnancy would not have been possible. All of these individuals were raised as women, including the only one with a predominantly male mosaic karyotype.
There are a few reasons for what that 2009 study found. First, in the western world, when an intersex person is born with both sets of genitalia, genital mutilation is traditionally performed on them as infants to remove their penis and scrotum sack. Why? because it’s safer than doing a full hysterectomy and vagina removal on a newborn. The baby is then raised as a girl. As a girl, she is socialised to desire childbearing and believes that is her reproductive role. But she has been denied from birth her identity as both man and woman, intersex. I don’t think this is a good thing. Nor is the socialisation that only girls can get pregnant when intersex people can and do too. It is a western tradition that is outdated and oppressive, because forces every human that can get pregnant into the box of woman.
Outside the circa 2009 western centric bubble, intersex people are not mutilated directly after birth but often raised as intersex, and then choose themselves whether to live as a man or woman. This minority is fortunately becoming more recognised now in 2021.
A quick google comes up with a few examples, raised as men who could become pregnant if they wanted to...
There is Krittapak Duangchai, raised as a man in Lampang province, Thailand who in 2012 wanted to ordain as a monk at his local temple, just like nearly all Thai Buddhist men do at some point during their lifetimes. But he was banned as he is a hermaphrodite. With both vagina/uterus/cervix/menstruates and functioning penis/scrotum.
There is Xxxora from Ealing, West London. Raised as a boy, Xxxora went through art school at Goldsmith's College living as a man but later switched to a female persona, although now refers to herself as nonbinary and rejects being described as either male or female - and wants the government to recognise Xxxora as both, with a legal addition to official gender categories.
