what is the difference in definition between sex and gender
Sex = male and female. Gender = masculine and feminine. So in essence: Sex refers to biological differences; chromosomes, hormonal profiles, internal and external sex organs. Gender describes the characteristics that a society or culture delineates as masculine or feminine. So while your sex as male or female is a biological fact that is the same in any culture, what that sex means in terms of your gender role as a 'man' or a 'woman' in society can be quite different cross culturally. These 'gender roles' have an impact on the health of the individual.
