Age difference between parents influences parity and number of sons

ConclusionsAge difference between partners is important for reproductive success (with younger wives having higher reproductive potential) and is also related to number of sons. Older husbands might provide more resources for the family, thus facilitating production of well‐nourished male offspring. Future research should evaluate not only number of children but also their biological condition, health, and lifetime achievements in relation to the age difference between their parents.
