The point is that the uterine transplants into men (trans women) ship is sailing whether you like it or not.
Studies have been and are being done discussing the feasibility by addressing all the physiological barriers (hormones, blood supply, lingamentous support, immuno-suppression, assisted childbirth, etc) one by one. The conclusions of these studies is that these barriers are most probably surmountable. They’re conducting animal experiments right now on this, so obviously it’s already been cleared in terms of the participating nations’ bio-ethics boards that the potential benefit to humans outweighs the suffering of the animals.
The bio-ethics of uterine transplants specifically for men/trans women have also been discussed since 2014 when it first seemed a remote possibility. This discussion is now trending towards a majority view that broadly supports it in terms of reproductive justice with the assertion that donors can be sourced ethically.
That’s the current state of things. Saying it’s not possible, it’s not ethical. Well you’re probably wrong on the first count and on the second, now is the time to speak up because the tide is taking that ship in the direction of saying it would be unethical to deny interior transplants for transwomen.
