Gender symbol

A gender symbol is a pictogram or glyph used to represent sex and gender, for example in biology and medicine, in genealogy, or in the sociological fields of gender politics, LGBT subculture and identity politics.

In his books Mantissa Plantarum (1767) and Mantissa Plantarum Altera (1771), Carl Linnaeus regularly used the planetary symbols of Mars, Venus and Mercury – ♂, ♀, ☿ – for male, female and hermaphroditic (perfect) flowers, respectively.^[1] Botanists now use ⚥ for the last.^[2]

In genealogy, including kinship in anthropology and pedigrees in animal husbandry, the geometric shapes △ or □ are used for male and ○ for female. These are also used on public toilets in some countries.

The modern international pictograms used to indicate male and female public toilets, 🚹︎ and 🚺︎, became widely used in the 1960s and 1970s. They are sometimes abstracted to ▽ for male and △ for female.^[3]

The three standard sex symbols in biology are male ♂, female ♀ and hermaphroditic ⚥; originally the symbol for Mercury, ☿, was used for the last. These symbols were first used by Carl Linnaeus in 1751 to denote whether flowers were male (stamens only), female (pistil only) or perfect flowers with both pistils and stamens.^[1] (Most flowering and conifer plant species are hermaphroditic and either bear flowers/cones that themselves are hermaphroditic, or bear both male and female flowers/cones on the same plant.) These symbols are now ubiquitous in biology and medicine to indicate the sex of an individual, for example of a patient.^[4][a]

Kinship charts use a triangle △ for male and circle ○ for female.^[6] Pedigree charts published in scientific papers use an earlier anthropological convention of a square □ for male and a circle ○ for female.^[7]

Before a shape distinction was adopted, all individuals had been represented by a circle in Morgan's 1871 System of Consanguinity and Affinity of Human Family, where gender is encoded in the abbreviations for the kin relation (e.g. M for 'mother' and F for 'father').^[8] W. H. R. Rivers distinguished gender in the words of the language being recorded by writing male kinship terms in all capitals and female kinship terms with normal capitalization. That convention was quite influential for a time, and his convention of prioritizing male kin by placing them to the left and females to the right continues to this day though there have been exceptions, such as Margaret Mead, who placed females to the left.^[9]

In linguistics, a 'grammatical gender' system is a specific form of a noun class system, where nouns are assigned to gender categories that are often not related to the real-world qualities of the entities denoted by those nouns. In languages with grammatical gender, most or all nouns inherently carry one value of the grammatical category called gender, typically 'masculine', 'feminine', and 'neuter'. In addition to U+2642 ♂ MALE SIGN and U+2640 ♀ FEMALE SIGN, Unicode encodes a symbol for the neuter gender, U+26B2 ⚲ NEUTER.

The modern gender symbols used for public toilets, 🚹︎ for male and 🚺︎ for female, are pictograms created for the British Rail system in the mid-1960s.^[10] Before that, local usage had been more variable. For example, schoolhouse outhouses in the 19th-century United States had ventilation holes in their doors that were shaped like a starburst Sun ✴ or like a crescent Moon ☾, respectively, to indicate whether the toilet was for use by boys or girls.^[11] The British Rail pictograms – often color-coded blue and red^{[citation needed]} – are now the norm for marking public toilets in much of the world, with the female symbol distinguished by a triangular skirt or dress, and in early years (and sometimes still) the male symbol stylized like a tuxedo.^[3]

These symbols are abstracted to varying degrees in different countries – for example, the circle-and-triangle variants (male) and (female) commonly found on portable toilets, sometimes abstracted further to a triangle △ (representing a skirt or dress) for female and an inverted triangle ▽ (representing a broad-shouldered tuxedo) for male in Lithuania.^[3]

In elementary schools, the pictograms may be of children rather than of adults, with the girl distinguished by her hair. In themed locations, such as bars and tourist attractions, a thematic image or figurine of a man and woman or boy and girl may be used.^{[citation needed]}

In Poland, an inverted triangle ▽ is used for male while a circle ○ is used for female.^[3]

In mainland China, silhouettes of heads in profile may be used as gender pictograms,^{[citation needed]} generally alongside the Chinese characters for male (男) and female (女).^[12]

Some contemporary designs for restroom signage in public spaces are shifting away from symbols that demonstrate gender as binary as a way to be more inclusive.^[13][14]

Since the 1970s, variations of gender symbols have been used to express sexual orientation and gender politics. Two interlocking male symbols (⚣) are used to represent gay men while two interlocking female symbols (⚢) are often used to represent lesbians.^[15] Two female and two male symbols interlocked represent bisexuality, while an interlocked female and male symbol (⚤) represents heterosexuality.^[16]

The combined male-female symbol (⚥) is used to represent androgyne people;^[17] when additionally combined with the female (♀) and male (♂) symbols (⚧) it indicates gender inclusivity,^{[citation needed]} though it is also used as a transgender symbol.^[18][19][17] The male-with-stroke symbol (⚦) is used for transgender people.^[17]

The Mercury symbol (☿) and combined female/male symbol (⚥) have both been used to represent intersex people.^[20][16] A featureless circle (⚪︎), neuter symbol (⚲), and the alchemical symbol (🜬) are used to represent both asexuality and non-binary people.^[21][16]

Since the 2000s, numerous variants of gender symbols have been introduced in the context of LGBT culture and politics.^[16] Some of these symbols have been adopted into Unicode (in the Miscellaneous Symbols block) beginning with version 4.1 in 2005.
