Intersex is a term for those born with physical sex characteristics that cannot be traditionally classified as wolffian (male) or müllerian (female). Variations may appear in a individual’s chromosomes, hormones, genitalia, gonads, secondary sex characteristics, or some combination of these things.
Intersex does not describe a specific body type but rather is an umbrella term for a broad range of variations/traits. Some intersex individuals may closely resemble one of the binary sexes, while others are closer to in between. An intersex individual may have characteristics of both the wolffian and müllerian sexes, characteristics that fall somewhere in-between wolffian and müllerian, and/or characteristics that don't fall into either.
Intersex is included in the LGBT+ community, though not all intersex individuals consider themself to be LGBT+ on the basis on being intersex. This is largely a personal choice based on how one's status as intersex has (or hasn't) affected their experiences.
 
The Intersex Pride Flag was created by Morgan Carpenter in 2013. Yellow and purple were chosen for the design as alternatives to the strongly-gendered colours of blue and pink. The purple circle in the middle symbolizes "wholeness and completeness" as well as "the right to be who and how we want to be."
