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.

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.

This study investigates correlates of the post-partum sex taboo. Empirical analysis identifies several predictors, from extensive agriculture to localized kin groups. The authors suggest that the taboo imposes a burden on women and unmarried or monogamous young men, and it is best maintained in a community in which elders are in firm control and married women are considered outsiders due to village exogamy.

This article examines reasons for the variation in sexual foreplay practices cross-culturally. Results suggest that exclusive mother-child sleeping arrangements is significantly associated with the presence of foreplay.

This article uses factor analysis to identify the key variables underlying the many cross-cultural associations reported by Textor (1967). Twelve factors are identified.

This article seeks to examine the distribution and frequency of bride-theft. Tylor's (1889) findings between various forms of marriage by capture and certain other social instituions are confirmed.

This article examines two hypotheses concerning the length of the post-partum sex taboo. Analysis suggests that both animal husbandry (with consumption of domestic animals’ milk) and monogamy (which restricts men’s options for sexual partners) are inversely associated with the length of the post-partum sex taboo.

This study investigates theories of male initiation ceremonies. The author examines a hypothesis related to child-rearing variables (sleeping arrangements and post-partum taboo) and rejects it based on empirical analysis. An alternative hypothesis related to male solidarity is offered.

This paper suggests that polygyny may be best explained by uneven sex ratios, particularly an excess of women while men are engaged in warfare. The author also considers Whiting’s 1964 theory that used post-partum sex taboos to explain polygyny. These two theories are tested cross-culturally and results suggest that polygyny is a response to an unbalanced sex ratio in favor of women.

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.
