What makes some young men stay and not abandon their child?

My parents have been married for nearly 24 years now. They tied the knot 4 months before I was born.

However, my father was just 20 when he got my then 19 year-old mother pregnant. That's sweet that he didn't bail out on her nor place all the responsibility on her. He went through with a proposal and then marriage.

Just like there are cowards that bail out, what makes some young men do the opposite; staying and not abandoning their child? We all know oxytocin is the chemical during and after pregnancy for us, to bond with our babies. How does it work in men? What makes some like my father (even when they're young guys) want to bond with the woman and child?
