The term sex primarily refers to the biological and physiological characteristics that define organisms as male or female, encompassing aspects like chromosomes (typically XX for female and XY for male in humans), hormones, gonads (ovaries or testes), and anatomy (internal and external genitalia and secondary sex characteristics). Biologically, sex is fundamental to reproduction, often involving the combination of genetic material from two individuals. In a broader social context, the term is sometimes used to denote sexual activity or sexual intercourse.
