delusional misidentification syndrome delusion of sexual transformation A extremely rare type of delusion, often linked to seizure or, occasionally, to schizophrenia, in which an individual believes that their body has spontaneously transformed into that of a different gender-related phenotype (for example, a person who identifies as male and has male genitalia believes that he has spontaneously grown breasts and a vagina and has lost his penis and testicles). Delusion of sexual transformation is entirely unconnected to a person being transgender. A transgender person almost always recognizes their current phenotype and seeks out treatment to change that phenotype; those experiencing sexual transformation delusions believe that their phenotype has already changed or is changing for any of various reasons related to the delusion. For instance, the 19th century German judge Daniel Schreber believed that "rays" from God physically and miraculously transformed him into a woman. ictal delusion of sexual transformation sex change delusion sexual transformation delusion delusion of sexual transformation A extremely rare type of delusion, often linked to seizure or, occasionally, to schizophrenia, in which an individual believes that their body has spontaneously transformed into that of a different gender-related phenotype (for example, a person who identifies as male and has male genitalia believes that he has spontaneously grown breasts and a vagina and has lost his penis and testicles).
