Intersex refers to those of us born with physical sex characteristics that are not considered typical for male or female.
Who is considered intersex is a matter of debate, but some estimates are that around 1.7% of the population has some sort of “difference of sex development” (DSD), which include atypical differences or combinations of chromosomes, gonads or genitals. It is very likely that you know someone with a DSD or intersex variation, who may need your support.
As society wrestles with all types of questions relating to sex and gender, an understanding of sex development including intersex is crucial in addressing these questions with nuance and care.
