Pseudohermaphroditism is an outdated[1] term for when an individual's gonads were mismatched with their internal reproductive system and/or external genitalia.
The term was contrasted with "true hermaphroditism" (now known as ovotesticular syndrome), a condition describing an individual with both female and male reproductive gonadal tissues.
Between 8 and 12 weeks, human male fetuses become externally distinct as androgens enlarge the phallus and produce a penis with a urethra and scrotum.
Persistent Müllerian duct syndrome was considered a form of pseudohermaphroditism, developed through Müllerian-inhibiting factor defects.
[16][17] Klebs had included the term as a synonym for the earlier coined, "spurious hermaphroditism" (which he referred to as Schein-Zwitter in German).
[23][30] Additionally, intersex activists have noted that: "The qualifiers 'pseudo' and 'true' are even more harmful [than hermaphrodite on its own], because they imply a sort of authenticity, or lack of same, that carry powerful emotional baggage".
