In the 1970s, American psychologists defined clear differences in the definition of gender vs. sex. The term “gender” was introduced in the 1970s to define characteristics and socially developed traits that were attributed to male and female patients. “Sex” was defined as the biological and genetic mechanisms that separate male and female patients, such as the chromosomes, genes, hormones and areas of cerebral development or other genetic-based physical attributes. Gender can be selected and modified. Sex is what one is born. The physical characteristics of sex can be modified, but this does not determine gender, which is the behavior, cultural and psychological traits of being a man or woman.
