This SciShow video reviews data concerning differences in the brains of biological males and biological females. The writers are careful to mention that research on this topic does not account for transgender or intersex individuals, and that neuroscience research as a whole is heavily focused on studying the brains of male humans and animals. You may also wish to discuss with students about the definition of “biological sex” and how that definition has changed throughout history.

The age of the onset of puberty has also fallen for those assigned male at birth, from an average of age 11 to 10.5.”
