> Your trick is ignoring the stronger argument which is it's very likely that a trans woman will get pregnant after a uterus transplant at some point during our lifetime.
Harvesting the uterus of a woman and hosting it inside a man does not make him a member of a female sex.
Even if a womb was lab-grown somehow, rather than poached, it's highly unlikely his body would be compatible with pregnancy. And there would be massive ethical concerns in performing this experiment, given that this is an attempt to artificially create and grow a new human life in a body fundamentally unsuited to this task.
