Genetics

Continuum

Brain Structure

Differentiation

Fetal Development

Fetal hormones, drugs, chemicals, or environmental toxins drive sexual differentiation.

Brain Biology

Gender identity and sexual orientation are set in the biology of the brain structure during fetal development. Neither is a choice. 

Research is ongoing.
