Yes—many people, researchers, and major medical and social science organizations distinguish gender from biological sex, though there is ongoing debate about how separate the two concepts are and how they should be understood.

• Biological sex generally refers to physical characteristics such as chromosomes, reproductive anatomy, hormones, and other biological traits. Most people are classified as male or female at birth, though some people are intersex and do not fit typical definitions of either sex.

• Gender generally refers to social, cultural, psychological, and personal aspects of being a man, woman, both, neither, or another gender identity. It includes gender roles, expectations, and how individuals understand themselves.

Those who support the distinction argue that biological traits and personal/social identity are not always the same thing, making separate concepts useful.

Others argue that gender is fundamentally rooted in biological sex and that separating the two too strongly can create confusion or obscure important biological realities.

As a practical matter, treating gender and biological sex as related but distinct concepts is the dominant approach in contemporary medicine, psychology, and much of the social sciences. However, there remains significant public, philosophical, and political disagreement about the implications of that distinction.
