I've wondered about the possibility of transplanting not just the womb, but the rest as well. I know nothing of medical science, so in my mind it's tissue, and why can't it work if it's a match for someone like a kidney or liver or heart? I know the reproductive organs do much more than these others. I've also wondered about the whole stem cell thing. What if one day a full set of reproductive organs could be grown from a person's own cells?
In any case, I think if nothing else, this is a step in the right direction.
