Decided not to be a parent isn’t just a woman’s personal choice. Plenty of men have decided fatherhood is not for them either, like Jon Hamm.
“I’d be a terrible father! I see my friends who have children and I’m like, ‘Dude, how are you even upright, much less here at work at 6 a.m.?’” he said in 2012.
