And some think you have to have both ovarian and testicular tissue to count as intersex. Some people live and die with intersex anatomy without anyone including themselves ever knowing. We work to build a world free of shame, secrecy, and unwanted genital surgeries for anyone born with what someone believes to be non-standard sexual anatomy. Humans decide whether a person with XXY chromosomes or XY chromosomes and androgen insensitivity will count as intersex. But in human cultures, sex categories get simplified into male, female, and sometimes intersex, in order to simplify social interactions, express what we know and feel, and maintain order. For example, a person might be born appearing to be female on the outside, but having mostly male-typical anatomy on the inside. Rather than trying to play a semantic game that never ends, we at ISNA take a pragmatic approach to the question of who counts as intersex. To better explain this, we can liken the sex spectrum to the color spectrum. In practice, different people have different answers to that question. Humans today, typically doctors decide how small a penis has to be, or how unusual a combination of parts has to be, before it counts as intersex. Home What is intersex? Or a person may be born with genitals that seem to be in-between the usual male and female types—for example, a girl may be born with a noticeably large clitoris, or lacking a vaginal opening, or a boy may be born with a notably small penis, or with a scrotum that is divided so that it has formed more like labia. In the same way, nature presents us with sex anatomy spectrums.
