Gender symbol - wikipedia Gender symbol A gender symbol is a pictogram or glyph used to represent either biological sex or sociological gender ( a terminological distinction originating in 1950s sociology ) in either biology, medicine, genealogy or selective breeding, or in sociology, gender politics, LGBT subculture and identity politics. Pictograms used to indicate male and female public toilets became widely used beginning in the 1960s. The shape of the Mars symbol has been likened to an iron - tipped spear ( i.e. a weapon mainly used by men ) and shape of the Venus symbol to a bronze mirror or a distaff ( associated with women in the past ).

They were first used to denote the effective sex of plants ( i.e. sex of individual in a given crossbreed, since most plants are hermaphroditic ) by Carl Linnaeus in 1751. They are still used in scientific publications to indicate the sex of an individual, for example of a patient. Pedigree charts published in scientific papers now more commonly use a square for male and a circle for female. Mars symbol ( U + 2642 ♂ ). The symbol for a male organism or man. Venus symbol ( U + 2640 ♀ ). The symbol for a female organism or woman. Square symbol ( U + 25A1 ). The symbol for a male family member in a pedigree chart. A triangle is also often used. Circle symbol ( U + 25CB ○ ). The symbol for a female family member in a pedigree chart. From the symbol of Mercury ( U + 263F ☿ ). This symbol is used to indicate a virgin female ( for example, in genetic analysis ). Also used in botany to indicate flower with both male and female reproductive organs. ☿ can also be used as a unisex symbol since intersex Hermaphroditus was a child of Hermes and Aphrodite ( Mercury and Venus ).

The first instance of this was the use of two interlocking male symbols to represent male homosexuality. Since the 2000s, numerous such variants have been introduced in the context of LGBT culture and politics. Some of these symbols have been adopted into Unicode ( in the Miscellaneous Symbols block ) beginning with version 4.1 ( 2005 ) : Main article : LGBT symbols § Gender symbols Unicode name hex dec Meaning INTERLOCKED FEMALE AND MALE SIGN ⚤ U + 26A4 & # 9892 ; Heterosexuality MALE AND FEMALE SIGN ⚥ U + 26A5 & # 9893 ; Male and Female DOUBLED MALE SIGN ⚣ U + 26A3 & # 9891 ; Male homosexuality DOUBLED FEMALE SIGN ⚢ U + 26A2 & # 9890 ; Female homosexuality MALE WITH STROKE SIGN ⚦ U + 26A6 & # 9894 ; Transgender MALE WITH STROKE AND MALE AND FEMALE SIGN ⚧ U + 26A7 & # 9895 ; Transgender MEDIUM WHITE CIRCLE ⚪ U + 26AA & # 9898 ; Agender Pagan gender symbols Neo-pagan male symbol ( `` blade '' ) Neo-pagan female symbol ( `` chalice '' ) The pagan symbols for male and female were popularized by Dan Brown in his novel, The Da Vinci Code.

(... ) In the 1970s, the British example was developed on a more comprehensive basis in the United States. In 1974, the US Department of Transportation commissioned the American Institute of Graphic Arts to create a set of pictograms to be used throughout public transport networks whether road, rail, air or sea.
