Prizing a male child, although seemingly an old fashioned notion, is still widespread.... This strong desire for boys in the family translates into a difference in fathering. Studies show that men play with boy babies more than girl babies and in general are more involved with their families if they have at least one son. Marriages, on average, last longer if there is a son. Even divorced fathers tend to see their sons more than their daughters (at least until adolescence).
