Biology and sexual orientation

Biology and sexual orientation is the subject of research into the role of biology in the development of human sexual orientation. No simple, single cause for sexual orientation has been conclusively demonstrated, and there is no scientific consensus as to whether the contributing factors are primarily biological or environmental. Many think both play complex roles. The American Academy of Pediatrics and the American Psychological Association have both stated that sexual orientation probably has multiple causes. Research has identified several biological factors which may be related to the development of a heterosexual, homosexual, or bisexual orientation. These include genes, prenatal hormones, and brain structure. Conclusive proof of a biological cause of sexual orientation would have significant political and cultural implications.
