Biological Studies
Biological studies have documented differences between male homosexuals and heterosexuals in their exposure to prenatal hormones (Levay 1994; Reinisch et al. 1991), brain structures (LeVay 1994), genetic markers (Hamer et al. 1993), and possibly other characteristics such as fingerprint patterns (see Downtown 1995 with regard to a University of Western Ontario study), possibly related to testosterone exposure (Jamison, et al. 1993). In addition, effeminate boys (who have a strong tendency to become adult homosexuals) are judged more attractive than other boys (Zucker, et al. 1993) which corresponds to Green's (1987) finding that parents of effeminate boys rated these as more "beautiful" babies than their other children.
