Wow, this is an interesting thread. I only read the first couple of pages, so sorry if this has already been mentioned, but from the last few posts it doesn't seem so.
This, or some of it, will be done much sooner than 50 years. I read a year or two ago that, in Sweden, they successfully transplanted a uterus into a cis woman who didn't have hers (I forgot if she had had it removed or if she was born without it). She did give birth to a healthy child and was considering having another baby before having the uterus removed. The plan was to remove it after she was done having children so she wouldn't have to be taking medicine to prevent rejection of the uterus for life. That was probably not the only case, and apparently there was one case in the US too.
It's only a matter of time before they do it with trans women, specially in a country like Sweden. Of course, it wouldn't be with out eggs, but that's also a matter of time.
I read that, separate from the above, there's research being done about removing the nucleus from an egg and replace it with the nucleus from a sperm. I read it longer ago, but I think the first experiments were successful, but I don't remember if they were using human cells yet. If they were they didn't implant the embryos at that time yet, we would have heard more about it, but they're getting there.
Sure, it's not the whole uterus, tubes and ovaries transplant, it will take more medical involvement, but it will bring us really close.
I'm moving to Sweden next year, and I'll do everything I can to find out what they are doing now and get involved, I'd get a uterus transplant once I have a partner and we're ready to have children.
