[1] Surya Monro states that the term is used to "indicate a person born with sex characteristics that are seen as typically male or female at birth, therefore not medicalized as intersex".
[4] Bödeker has written that she coined the term in the spring of 1999,[5] stating in English translation: Just as dialectically one could not be heterosexual if there were no homosexuals, just as one could not be cissexual if there were no transsexuals, so neither could one be endosex if there were not intersex people.
[2][9] The National Academies of Sciences, Engineering, and Medicine reported in 2020 that "some advocates and providers are increasingly using the term endosex to describe people whose reproductive or secondary sex characteristics align with medical binaries.
Brömdal and others state that sexuality education curricula privilege endosex bodies and experiences, promoting feelings of shame and secrecy in intersex students.
[16] In a media interview, a support group organizer states that intersex people undergo unnecessary medical examinations that would be prohibited on endosex women.
