Definitions

 * A gender identity where a person experiences a blending of genders, or feels that their identity is in between genders. Usually, but not always, people who identify as androgyne feel that their identity is a blending of male and female, or somewhere between those two genders. Androgyne people may or may not choose to present androgynously. - Ezgender Google Docs, 2020

Controversy
Androgyne originally was used as a word to describe intersex people, which has brought some people to conclude the word should be for intersex use only.

Flags
The most common androgyne pride flag was created by Tumblr user saveferris in 2014 through the blog pridearchive. The pink represents femininity, blue represents masculinity, and purple represents the mixing of the two.

The second most common androgyne flag was created by an unknown Tumblr user (possibly houisa or pride-flags-for-us) around 2015. The red symbolises woman, the blue symbolises man, the purple is a mix of them both, the yellow symbolizes being nonbinary, and the grey symbolizes neutrality.

Other
The most common androgyne symbol is a combination of the mars (man) and venus (woman) symbols. It's creator is unknown but it's thought to have originated in the 1990s. The symbol is usually vertical (⚨), but can also be written diagonally (⚦) or horizontally (⚩).

An alternate symbol is the Necker's Cube, an ambigious shape that Raphael Carter proposed using as a symbol for androgynes in 1996 because it is "either concave or convex depending on how you look at it".

Usage
According to the Nonbinary Wikia, 9.3% of people described themselves as androgyne in their last Gender Census.
