Could you name specific cultures where that is true?

Oh, my goodness ~ MOST of Europe until quite recent times. Africa ~ in most places ~ and throughout vast areas of Asia.

It's a common standard ~ show you can produce heirs FIRST then we'll talk.

The Church of the First Born (to the degree you can think of it as a "culture" rather than a "religion") right here in America still does this. I think the problem is "in-determinant infertility".
