If it was done because some selfish woman wanted a “pet baby” without a husband or man around, it’s wrong. If it was done to help an infertile hetro couple, then when the time came, explain it to the teen.
I’m not sure I would tell the child in either case, unless their was a medical reason to do so.
With us humans who your parents are is less a matter of your genetics than your raising. As a species we have less diversity than a group of chimpanzees.(Our genetic parents could almost be anyone)
What we learn/observe from those who raise us dominates who and what we are as individuals relative to the rest of the world.
Neither scenario is acceptable, the “selfish” woman or the couple being “helped”. No one has any business playing God like this, regardless of their rationale.
