The purpose of this article is to examine circumcision and segregation of males at puberty. It is suggested that when the son has insufficient contact with his father due to the separation caused by polygynous relationships, the son may develop a feminine personality. The significance of this is compared with the significance of a close mother-son relationship.

This article examines the relationship between polygynous living quarter arrangements and the presence or absence of circumcision and segregation of males at puberty. The amount of contact between the father and son is also examined as a factor.

This article explores the interrelated roles of male parental investment (males' infant/child care and resource provisioning) and male-male competition (variation in male status) on the degree of monogamy or polygyny in a society. Marlowe argues that Degree of parental investment affects females' interest in resource-shopping versus gene-shopping. Also discussed is the idea that male-male competition affects males' inclination toward harem-defense or coercive polygyny. Particular attention is paid to variation in parental investment and male stratification across subsistence types.

This article examines the "sexual conflict" hypothesis which predicts that male genital mutilation should be associated with polygyny and a reduction in the frequency of extramarital sex. Male genital mutilation (MGM) rituals should be highly public and facilitate access to social benefits. Support for these assumptions is provided.

The significance of the son's insufficient contact with his father during infancy in regard to circumcision and segregation is examined. This article suggests that it is not the long postpartum sexual taboo but the separation of each co-wife that is instrumental in bringing about circumcision and segregation. Expands on Kitahara 1974.
