Male homosexuality and maternal immune responsivity to the Y-linked protein NLGN4Y

11 Dec 2017

Abstract excerpt

We conducted a direct test of an immunological explanation of the finding that gay men have a greater number of older brothers than do heterosexual men. This explanation posits that some mothers develop antibodies against a Y-linked protein important in male brain development, and that this effect becomes increasingly likely with each male gestation, altering brain structures underlying sexual orientation in...
