I read about this recently while I was looking into methods of conception for trans people. A donor is one possibility but I also read that having one's own uterus grown from their cells in a lab is also going to be possible somewhere down the road. I'm assuming that in those cases the uterus would not have to be removed since it would be created using the patient's own cells.
Because they're also looking into ways of allowing two people of the same birth assignment conceive a child together, including a method of creating egg cells from AMAB bone marrow, it'll probably be possible before long for trans women to carry their own biological children formed from their own eggs.
I have heard from a few trans women who were dysphoric about creating children with their sperm. Not everyone is like this but I think for the people who do feel this way technology is definitely heading in the right direction and before long trans women will be able to reap all the benefits of motherhood.
I also heard somewhere that the trans uterine transplant is predicted to happen sometime before 2020.
