PWHN/People Who Have Neither, IWHV/Individuals Who Have Neither, or PHN/People Having Neither (formerly PON/People of Neither and ION/Individuals of Neither), is a term for anyone who has neither a penis or vagina, regardless of gender.
It includes individuals who were born neither with a penis or a vagina and individuals who have had sex reassignment surgery and have neither a penis or a vagina. The term includes some intersex individuals, transneutral individuals who have have sex reassignment surgery (to a neutral sex), and some transsex/altersex men and women.
This term is made to combat the ideology that having a penis is what makes one a man and having a vagina is what makes one a woman, and is made promote gender-neutral language and terms. The term was also made for more simplicity in describing genitalia in medical situations, such as sex education, as saying "intersex" would leave out many altersex and trans individuals.
The term was coined by Cryptocrew on March 13, 2021 in order to help relieve dysphoria and discomfort in many genderqueer individuals. The alternate wordings of PWHN and PHN were created by Wiki user foreigntoolmaker on September 30th since some people were uncomfortable with PON. Weniviere, the coiner of the term, did not realize that the original wording "people/individuals of neither" sounded uncomfortable, due to English not being her first language, and has since acknowledged this grammatical mistake and embraces "PWHN/IWHN" as the main term.
