"Intersex" is a term that refers to variations in sex characteristics including chromosomes, gonads, sex hormones, or genitals that don't fit the standard binary definition of "male" or "female". It most commonly refers to individuals with ambiguous genitalia. However, in a medical context, it can also refer to conditions such as androgen insensitivity syndrome, XX male syndrome, and certain hormonal disorders like polycystic ovarian syndrome.
Intersex characters are frequently depicted as androgynous, either in a Dude Looks Like a Lady, Lady Looks Like a Dude, Pretty Boy, Bishōnen, or Bifauxnen manner. They are frequently uncomfortable about their bodies in a manner similar to gender dysphoria. Their intersex status often leads to a lot of internalized angst or angst that can be brought upon them by others. Intersex characters are also frequently depicted as villains, leading to Unfortunate Implications.
Historically, intersex people have been referred to as hermaphrodites, however the two are not the same and it is considered offensive to refer to intersex individuals as such. Some intersex people identify as transgender, especially if they're non-binary or if they were raised as one gender growing up but don't identify with it; however, not all intersex people are trans. Despite this, being intersex is often pinned under the LGBTQ umbrella, in part because they often face the same (or very similar) forms of discrimination, bigotry, and ignorance.
