Sex refers to a natural or biological feature. Gender refers to cultural or learned significance of sex.
According to Medilexicon's medical dictionary:
Sex is "The biologic character or quality that distinguishes male and female from one another as expressed by analysis of the person's gonadal, morphologic (internal and external), chromosomal, and hormonal characteristics."The word gender comes from Middle English gendre, which came from Old French, which in turn came from the Latin word genus, meaning "kind," "type," or "sort."
Gender is "The category to which an individual is assigned by self or others, on the basis of sex."
The word sex probably comes from Middle English, meaning "section" or "divide." In Latin, the word sex means the number "six."
