Okay, so there are male people, female people and intersex people.
It gets a bit odd because the plural of ‘intersex’ is still ‘intersex’. So it works out like this…
Works: A new scholarship is available to females.
WTF No!: A new scholarship is available to intersexes.
Works (I guess): A new scholarship is available to intersex.
Best: A new scholarship is available to female students.
Best: A new scholarship is available to intersex students.
Nouns objectify us whereas adjectives describe us. Objectification can often ‘other’ us when intersex people just want to live our daily lives just like anyone else.
Also never use the ‘-ual’ suffix. It drives me nuts to hear ‘intersexual’ because the ‘-ual’ suffix describes orientations, not people. People can be homosexual or heterosexual but ‘intersexual’ is not an orientation. The study of intersex people is just that, and not the study of ‘intersexuals.’
Then again, intersex can be a topic. If you’re doing research on how AIS bodies differ from CAH bodies, you could write, “I am researching intersex.” That’s really no different than writing, “I am researching chromosomes,” or, “I am researching genetics,” and is fine.
I hope this helps?
