This article reviews psychological, sociobiological, and cultural materialist theories on male homosexuality. The author tests hypotheses focusing on parent-child relations, the gender of childhood companions, and residence patterns. Only the gender of childhood companions was significantly associated with homosexuality.

This article draws on psychoanalytic theory and a previous study by Whiting (1964) to test the relationship between parent-child sleeping arrangements, particularly the implied social distance of fathers, and the presence of circumcision for males. Circumcision is assumed to be a social correction for mother-oriented personality in sons.

The present research inquires into the effects, if any, that male status and power have on extramarital sex, parental investment, and polygyny.

There was no support for an association between male extramarital sex and parental investment.

A variety of operational hypotheses are supported for both male and female initiation ceremonies.
