Similarly, researchers from University of California, Berkeley, found that “girls who live in homes without a biological father physically mature sooner than those who live with their biological father.” Their relationships with their fathers can literally prevent them from getting pregnant. The paper suggests that this may be because unrelated men in the home “give off pheromones that set off the girls’ biological clocks.” Unfortunately, in some cultures and previous generations, many fathers didn’t show their children affection. Their role was simply to provide for their family. When I was growing up, I sometimes wished for more affection from my father. Though I don’t blame him for my bad choices, I think that I sometimes stayed in unhealthy relationships because I really longed for attention.
