ABSTRACT
Number of older brothers (or "fraternal" birth order) predicts a homosexual orientation in men but not in women. In this paper, I review recent research on the fraternal birth order effect. For example, I present a recent study using two national probability samples that indicates that number of older brothers increases homosexual attraction but not homosexual behaviour/experience in men. In addition, I present a study using Canadian data indicating that fraternal birth order may interact with height to predict sexual orientation in men such that a homosexual orientation is most likely to occur in men who have a high number of older brothers and a shorter stature. Results of these and other recent studies are discussed in relation to biological and psychosocial theories of the fraternal birth order effect.
