I would now like to talk about intersexuality. Most people will probably think of confused genitalia when they hear the word intersex. However, I think that the broadest definition of intersexuality is when any part of a persons body does not match the gender of other parts of their body. I therefore believe that transgenderism (where the brain is a different gender to the rest of the body) is a form of intersexuality.
There are brains of females and brains of males, but there are no female or male brains, in the sense that our brains are intrinsically sexed, and that there is a distinct category "cerebral/encephalic sex".
See:
Lise Eliot: You donβt have a male or female brain β the more brains scientists study, the weaker the evidence for sex differences
"Intersexuality" is an umbrella term for
disorders of sex development (DSDs) defined as
"congenital conditions in which development of chromosomal, gonadal, or anatomical sex is atypical." There is no mentioning of a "cerebral/encephalic sex"βnot even any implicit mentioning, because the anatomy referred to in "anatomical sex" doesn't include brain anatomy!
See:
Consensus statement on management of intersex disorders
The term "intersexuality" is misleading, because it wrongly suggests that all intersexuals are
neither female nor male, or
both female and male. Actually,
given the biological definition of sex in terms of gametes/gonades, the only intersexuals who are not classifiable as
either female or male are the very few ones
lacking both ovaries (ovarian tissue) and testicles (testicular tissue), and the very few ones
having both ovaries (ovarian tissue) and testicles (testicular tissue). These people are a tiny minority among the tiny minority of intersexuals.
An intersexual female or male can be transsexual or "transgender". For example, a male person with some form of DSD can desire to be a woman. However,
nearly all transsexual persons have no form of DSD, and thus aren't intersexual.
Transsexuality isn't a form of intersexuality, since this would mean that having some form of DSD is a necessary condition of being transsexualβwhich it is not!
