It is also possible that men (generally and traditionally) are wired or brought up to consider progeny in terms of expansion of bloodline, as for instance conquering in order to acquire and dominate.

We can notice for instance that practically all societies use the father's name as last name for identification, that is what is important to men. An exception of to that, that I am aware of is the matriarchal society of the Ashanti in Ghana, where the mother plays that role. The father may not know all his children, but the mother does as well as their fathers.

Generally and traditionally the women's approach is different, it is as rightfully noted more nurturing. After all nature has endowed them biologically for that.

That said both feel the connection to progeny with the ulterior subtle motivation of a future body, that has to be baked in regardless of gender or species. And, being a disinterested (useless) father does not negate the need for the next body. Understandably nurturing and reproduction are two very distinct characteristics.
