In simple terms, intersex is a description of a person’s biological sex when their physical characteristics don’t fit standard definitions of male or female.
These are individuals who, for example, might have both ovaries and a penis, or testicles and breasts, etc. There can also be significant hormonal imbalances, where the sex chromosomes (X and Y) don’t follow the “typical” patterns of XX (female) or XY (male).
It is estimated that being born intersex is about as common as being born with red hair!
Intersex is not the same as hermaphrodite, a term that refers to having fully functional male and female reproductive organs — something not possible in mammals, including humans.
Naturally intersex bodies are usually healthy. Intersex people may sometimes require hormone treatment, but often this is due to previous medical interventions made by doctors.
