"Can I learn to drive?"
"No, you're not old enough"
"But my friend is already driving and he's 12"
"OK, when you turn 12 you can too."
In that case only thing I can suggest is to pass a law to assess the eligibility and maturity of people if they want to have children and issue a permit if they are suitable to have and raise children and otherwise they cannot have children.
As they say, you can't fix stupid.
