The most important thing to remember about Gender and Sex is that Sex ≠ Gender. Sex is what is biologically assigned to you at birth, this can be Male, Female or Intersex. Do not confuse intersex with transgender or gender identity! Intersex is a medical condition in which the person has both male and female chromosomes. This person may have both male and female genitalia, male genitalia with female organs, or any other variation that prevents them from being distinctly male or female.
