Hormones and Homosexuality

Excerpt

There has been a recent resurgence of interest in the investigation of endocrine factors that are associated with human sexual behavior. The competitive protein-binding and radioimmunoassay methods for precise measurement of hormone levels provide a significant advance in accuracy beyond that of previous methods.

Unless sufficient amounts of androgens are present during critical stages of fetal (or neonatal) development, differentiation will always occur as a female, regardless of genetic programming.
