R. Blanchard et Af. Bogaert, Birth order in homosexual versus heterosexual sex offenders against children, pubescents, and adults, ARCH SEX BE, 27(6), 1998, pp. 595-603
Homosexual men erotically attracted to physically mature partners typically
have more older brothers than comparable heterosexual men. We investigated
whether late fraternal birth positions also occur in homosexuals attracted
to children or pubescents. Probands were 710 sex offenders from Gebhard et
al.'s (1965) study of sexual offending. Homosexual offenders against adult
s and pubescents had later fraternal birth positions than heterosexual offe
nders against adults and pubescents, respectively; there was no difference
between the homosexual and heterosexual offenders against children. Results
provide some evidence that homosexuality in men attracted to immature male
s is etiologically related to homosexuality in men attracted to mature male
s.
