This chapter in The Plasticity of Sex highlights a shift in understanding core gender identity—from being shaped solely by social and familial factors to a more complex interplay of genetic, hormonal, and neuroanatomic influences. It emphasizes that the sexually dimorphic brain serves as a key anatomical foundation for psychosexual development, shaped by genes and hormones during prenatal and pubertal stages. The authors call for further research to unravel how these biological and psychosocial factors interact to form gender identity.
