A father throwing away his sons effectively throws away his competition for young females to take as wives. Because women are considered prime property in the Fundamentalist Polygamist religions, and as the pool of eligible women shrinks, polygamist men look for younger and younger wives to fulfill their needs. Some men marry girls who are little more than children, or at least make contracts with a young girl s father for marriage at a later date. The usual age of marriage for polygamist girls, is between twelve and fourteen. By the time a girl is twelve or even younger in a polygamist culture, older males have already noticed her and are vying and negotiating for her hand in marriage with whichever prophet leads their church.
