> Unless the procedure has changed dramatically, it requires a functional vagina. Neovaginas are qualified but I would not expect most male-identified people to opt for vaginoplasty.

First, male-identified people can be born biological female. It's an identity.

Second, the procedure doesn't exist for biological males to begin with right now, neovagina or not. A neovagina is physiologically not a biological female vagina to begin with anyway so I wouldn't help at all with the gestation. Birth can be done via C-Section.

You'll be surprised to learn that neovaginas are also possessed by cis women. Trans men requiring vaginoplasty and receiving a uterine transplant are the nichest possible edge case, your "gotcha" is pure distraction.

Trans women will receive the modern* uterine transplant operation, this I can state with certainty. Birth is done via C-section as a requirement of the UTx operation, the vagina is required for discharge. I haven't been able to pay attention to the operation for a few years, but it is clear that you are operating from uninformed conjecture.

*The first uterine transplant was performed on a trans woman in Germany in 1930, Lili Elbe. This pioneering surgery lead to her death, as transplantation medicine was not adequately developed at that point in time.
