The word “make” does a lot of heavy lifting when it comes to pregnancy. A word like “nurture” might fit better. Once the sperm and egg combine, it starts doing its own thing, the mother’s body just provides resources for it to continue growing and a safe place to do so for the first 9 months give or take.
So the way to make human egg cells would be to either be conceived as a female and have everything go well enough to grow those eggs, or probably some other methods involving introducing various chemicals to unspecialized cells to trick them into behaving as if that was happening.







Yeah, I was talking about the magic of science or extreme coincidences.
Ultimately (having read your other reply), I don’t think biological definitions are useful when it comes to social things like gender. It’s just trying to change the argument into an easier one. “What is normal?” vs “what is possible?” or “what is ok?”.
