Biology and sexual orientation : ウィキペディア英語版 | Biology and sexual orientation
The relationship between biology and sexual orientation is a subject of research. A simple and singular determinant for sexual orientation has not been conclusively demonstrated; various studies point to different, even conflicting positions, but scientists hypothesize that a combination of genetic, hormonal, and social factors determine sexual orientation. Biological theories for explaining the causes of sexual orientation are more popular,〔 and biological factors may involve a complex interplay of genetic factors and the early uterine environment.〔(【引用サイトリンク】title=Submission to the Church of England’s Listening Exercise on Human Sexuality )〕 These factors, which may be related to the development of a heterosexual, homosexual, bisexual or asexual orientation, include genes, prenatal hormones, and brain structure. ==Empirical studies==
