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, but research suggests that it is by a combination of genetic, hormonal, and environmental influences, with biological factors involving a complex interplay of genetic factors and the early uterine environment. Biological factors which may be related to the development of a heterosexual, homosexual, bisexual or asexual orientation include genes, prenatal hormones, and brain structure.
