Some intersex people have genitals or internal sex organs that fall outside the male/female categories — such as a person with both ovarian and testicular tissues. Other intersex people have combinations of chromosomes that are different than XY ( usually associated with male) and XX (usually associated with female), like XXY. And some people are born with external genitals that fall into the typical male/female categories, but their internal organs or hormones don’t.

"If a person’s genitals look different from what doctors and nurses expect when they’re born, someone might be identified as intersex from birth. Other times, someone might not know they’re intersex until later in life, like when they go through puberty. Sometimes a person can live their whole life without ever discovering that they’re intersex.
