Intersex, in humans and other animals, describes variations in sex characteristics including chromosomes, gonads, or genitals "that do not fit typical binary notions of male or female bodies". Such variations may involve genital ambiguity, and combinations of chromosomal genotype and sexual phenotype other than XY-male and XX-female. Intersex people were previously referred to as hermaphrodites, but the term has fallen out of favor as it is considered to be misleading and stigmatizing.
