We tested the kin selection hypothesis of male homosexuality using questionnaire data in a community sample of homosexual and heterosexual men. Homosexual men were no more likely than heterosexual men to channel resources toward family members. Indeed, heterosexual men tended to give more financial resources to siblings than homosexual men. Furthermore, homosexual men were somewhat more estranged from family members, especially from fathers and oldest siblings.
