The man does have a choice and responsibility in this decision. He can put on a condom, every time! Don’t take for granted that the woman is telling the truth about using birth control.
The male can affect whether the baby will have his DNA, but not whether a woman who wants a baby is going to get pregnant. Especially for low IQ, low social-status young women, getting pregnant out-of-wedlock is socially acceptable or even advantageous, and economically very advantageous. That's the problem. Politicians demagoguery about "deadbeat dads" is a diversion from the problem, ie part of the problem.
